The U.S.  economy grew at a healthy  pace for the first three  quarters of 1996,
confounding market analysts who predicted a significant  slowdown.  During 1995,
economic  weakness  prompted  the Federal  Reserve (the Fed) to make a series of
short-term  interest rate cuts,  culminating  in a  quarter-of-a-percent  cut in
January 1996.  This  expansionary  monetary policy helped speed the pace of U.S.
economic growth from an anemic 0.3% annual rate in the fourth quarter of 1995 to
2.0% in the first quarter of 1996. Growth expanded further to an impressive 4.7%
in the second quarter of the year (see the graph below).

[bar graph - data described below]

Stronger-than-expected  corporate earnings fueled increased  corporate expansion
and job  growth.  Nearly  two  million  new jobs were  created in the first nine
months  of the year,  sending  the U.S.  unemployment  rate to a  six-year  low.
Healthy  employment numbers and a strong performance by U.S. stocks led to fears
of inflationary  pressure and  expectations of an interest rate hike by the Fed.
As a result, U.S. bonds overall gave a lackluster performance.

But the expected surge in inflation  failed to  materialize.  For the first nine
months of the year,  inflation,  as measured by the consumer  price index (CPI),
grew at an annualized rate of 3.2%,  compared to the 2.5% inflation rate for all
of 1995 (the lowest  annual rate since 1986).  Because of this  apparent lack of
inflationary pressure, the Fed held interest rates steady through September.

But the economic  picture remains  uncertain.  The economy grew at a 2.2% annual
rate in the third  quarter,  and recent  economic  data seem to suggest that the
economy may be slowing. Market participants are no longer sure that the Fed will
raise  interest  rates this year, and some even contend that the Fed's next move
may be toward  lower  rates.  On the other hand,  signs of wage  inflation  have
surfaced in recent  employment  reports.  In spite of higher  interest rates for
most of this  year,  the  housing  market  has  remained  robust,  and  consumer
confidence  is high,  indicating  that the U.S.  consumer  may  still  have some
spending power.  Given the present state of economic  uncertainty,  it is likely
that  shifting  expectations  of Fed  interest  rate  policy may have more of an
impact on U.S.  financial  markets in the coming  months than any actual move by
the Fed.

                                 MARKET SUMMARY
                             MORTGAGE PASS-THROUGHS
             by the Benham Mortgage-Backed Securities Portfolio Team

NOTE: We suggest that you review the Investment  Fundamentals and U.S.  Economic
Review sections before you read this section.  Terms marked with an asterisk (*)

Interest rate shifts  continued to have an impact on the performance of mortgage
pass-throughs*  during the six-month  period ended September 30, 1996.  Interest
rates did not move in a  continuous  direction  over the period;  instead,  they
fluctuated in waves,  primarily moving when the national employment reports were
released (see page 1). Despite these short-term  gyrations,  interest rates were
relatively well behaved overall.  As a result,  the period was a fairly good one
for mortgage-backed securities investors.

In the relatively stable interest rate  environment,  the higher yields of ARMs*
and GNMAs* enabled them to outperform comparable Treasury securities. The Lehman
Brothers  ARM  Index  had a total  return  of 3.03%  for the  six-month  period,
outpacing  the 2.72% total  return of the Salomon  Brothers  One- to  Three-Year
Treasury  Index.  The Salomon  Brothers  30-Year GNMA Index posted a 2.74% total
return, compared to a 2.16% return for the Salomon Brothers Three- to Seven-Year
Treasury Index.

After  mortgage  rates rose back above 8% in February and March,  the prepayment
wave that hampered the returns of  mortgage-backed  securities early in the year
dwindled  rapidly  (see the  graph  on page 3).  By May,  prepayment  fears  had
diminished,  and mortgage refinancing activity had returned to more historically
normal  levels.  While  prepayment  activity  was fairly  light over the period,
homeowners  appear to be more fully  apprised than ever about their  refinancing
options.  An  example  of this was the surge in new ARMs that were  issued  this
year.  Over  30% of new  mortgages  issued  so far in 1996  have  been  ARMs,  a
significant  increase from 1995 levels.  As interest  rates shifted early in the
period,  the  difference  between ARM rates and  30-year  fixed  mortgage  rates
increased  to around 200 basis  points.*  We  believe  that this  prompted  many
homeowners to choose adjustable rate mortgages over more

traditional  fixed-rate  mortgages.   While  the  increase  in  adjustable  rate
mortgages should have no effect on refinancing activity in the near-term, it may
play a role three to five years from now.

Interest rates began to fall toward the end of October,  leaving the outlook for
mortgage-backed  securities  uncertain.  For now, moderating economic growth has
caused  optimism that the Federal Reserve will leave  short-term  interest rates
unchanged.

PLEASE NOTE:  Yields and total returns are based on historical Fund  performance
and do not guarantee  future results.  The Fund's share price,  yields and total
returns will vary, so that shares, when redeemed, may be worth more or less than
their original cost.

                             PERFORMANCE DEFINITIONS
Net Asset Value (NAV) Range  indicates the Fund's share price movements over the
stated period and can be used to gauge the stability of the Fund's share price.

Yields are a way of showing the rate of income the Fund earns on its investments
as a  percentage  of its  share  price.  The  30-Day  SEC Yield  represents  net
investment  income  earned by the Fund  over a 30-day  period,  expressed  as an
annualized  percentage  rate based on the Fund's  share  price at the end of the
30-day  period.  The SEC yield  should be  regarded as an estimate of the Fund's
rate of  investment  income,  and it may not  equal  the  Fund's  actual  income
distribution  rate, the income paid to a  shareholder's  account,  or the income
reported in the Fund's financial statements.

Total Return figures show the overall  dollar or percentage  change in the value
of a  hypothetical  investment  in the Fund and  assume  that all of the  Fund's
distributions  are  reinvested.  Average  Annual Total  Returns  illustrate  the
annually compounded returns that would have produced the Fund's cumulative total
returns if the Fund's  performance  had been  constant  over the entire  period.
Average annual total returns smooth out variations in a fund's return;  they are
not the same as year-by-year  results.  For fiscal  year-by-year  total returns,
please refer to the Fund's "Financial Highlights" on page 20.

                              MANAGEMENT DISCUSSION

Q:       How did the Fund perform?

A:       The Fund  continued to perform well in comparison  with its peers.  For
         the year ended  September 30, 1996,  the Fund's total return was 5.74%,
         compared to the 4.31%  average  total  return for its peers in Lipper's
         "Adjustable  Rate Mortgage Funds" category (see the Lipper  Performance
         Comparison  on page 5).  While the  Fund's  total  return was 143 basis
         points* higher than the category  average return,  the poor performance
         of a few ARM funds continued to depress the category's results. Perhaps
         a better  indication of the Funds performance was its ranking of 23 out
         of 53 funds  based on total  return.  The Fund  also  managed  a strong
         performance  over the six months ended  September  30, 1996,  posting a
         3.00% return.

Q:       Why did the Fund perform well against its peers?

A:       The Fund's relatively  conservative  positioning  compared with many of
         the funds in its Lipper category was the primary reason.  Our main goal
         is to provide  investors  with a high degree of price  stability.  This
         strategy is intended to help the Fund generate  returns  primarily from
         yield rather than from price appreciation.

Q:       How did you position the Fund to accomplish this goal?

A:       We  concentrated  on ARMs* with  relatively  high coupon  rates,  which
         helped  keep the Fund's  duration*  short in  comparison  with its peer
         group  throughout the period.  Many of these  high-yielding  securities
         also have fairly high lifetime caps (for further information concerning
         lifetime  caps,  see  the  explanation  of   Adjustable-Rate   Mortgage
         Pass-Throughs  on page 14), which makes them less  susceptible to price
         volatility  when  interest  rates  increase.  This  positioning  helped
         significantly  during the rising interest rate environment in the first
         half of 1996.

                              MANAGEMENT DISCUSSION
                       (Continued from the previous page)

Q:       According  to the  composition-by-security-type  chart  on page 6,  the
         amount  of ARMs  held in the Fund  increased  dramatically,  while  the
         amount of CMOs* decreased. Why the change?

A:       During the first quarter of 1996,  short-term CMOs worked very well for
         the Fund by insulating  it from price  volatility.  However,  the price
         difference between securities that reset monthly (like the Fund's CMOs)
         as opposed to yearly  increased  significantly  in May. This  situation
         caused ARMs that reset yearly to become more  attractively  valued than
         CMOs.  Therefore,  we decreased our CMO holdings from 36% to 13% during
         the six-month period.

         We replaced the Fund's CMOs with ARMs, increasing our holdings from 60%
         on March 31 to 80% by  September  30. By  purchasing  ARMs with  yearly
         resets,  we were able to pick up extra yield for the Fund while  adding
         very little  share-price  volatility.  As an added  precaution  against
         unwanted   volatility,    we   also   purchased   premium*   "seasoned"
         ARMs--securities backed by mortgages that are five to six years old and
         are therefore  less likely to be refinanced  than more recently  issued
         ARMs.  As a result,  premium  seasoned ARMs  typically  have less price
         motion either up or down when interest rates fluctuate.

Q:       Is this why you  increased  the  amount  of ARMs  that are reset on the
         one-year T-bill while decreasing the amount of ARMs that reset based on
         COFI* (see the ARM reset schedule on page 6)?

A:       Yes. As the probability that the Federal Reserve might raise short-term
         interest rates  increased (see page 1), we decreased the amount of COFI
         ARMs by 15%. We sold these securities  because ARMs that reset based on
         COFI have limited  liquidity  and perform  poorly in a rising  interest
         rate  environment.  We replaced  these COFI  securities  with ARMs that
         reset against the one-year T-bill, increasing these holdings by 20%.

Q:       What are your plans for the Fund over the next six months?

A:       We will likely  maintain the Fund's  defensive  posture  going  forward
         unless the outlook for mortgage-backed securities and interest rates in
         general  changes   dramatically.   Moderating  economic  growth  caused
         interest  rates  to  trend  lower  during  October,  but our  focus  on
         share-price  stability  means that we commonly  retain a rather bearish
         outlook on the economic  environment to reduce capital losses. In doing
         so, we are often able to avoid  unpleasant  surprises  when the outlook
         for bonds  suddenly  shifts  directions.  However,  if the bond  market
         continues to rally, we may extend the Fund's duration slightly.

returns will vary, so that shares, when redeemed, may be worth more or less than
their original cost.

                             PERFORMANCE DEFINITIONS
Net Asset Value (NAV) Range  indicates the Fund's share price movements over the
stated period and can be used to gauge the stability of the Fund's share price.

Yields are a way of showing the rate of income the Fund earns on its investments
as a  percentage  of its  share  price.  The  30-Day  SEC Yield  represents  net
investment  income  earned by the Fund  over a 30-day  period,  expressed  as an
annualized  percentage  rate based on the Fund's  share  price at the end of the
30-day  period.  The SEC yield  should be  regarded as an estimate of the Fund's
rate of  investment  income,  and it may not  equal  the  Fund's  actual  income
distribution  rate, the income paid to a  shareholder's  account,  or the income
reported in the Fund's financial statements.

Total Return figures show the overall  dollar or percentage  change in the value
of a  hypothetical  investment  in the Fund and  assume  that all of the  Fund's
distributions  are  reinvested.  Average  Annual Total  Returns  illustrate  the
annually compounded returns that would have produced the Fund's cumulative total
returns if the Fund's  performance  had been  constant  over the entire  period.
Average annual total returns smooth out variations in a fund's return;  they are
not the same as year-by-year  results.  For fiscal  year-by-year  total returns,
please refer to the Fund's "Financial Highlights" on page 21.

Salomon Brothers,  Inc. 30-Year GNMA Index, over the past 10 years. Although the
investment  characteristics  of the index are similar to those of the Fund,  the
securities  owned by the Fund and those  composing  the  index are  likely to be
different,  and securities that the Fund and the index have in common are likely
to have different  weightings in the  respective  portfolios.  Investors  cannot
invest directly in the index.

PLEASE NOTE: The line  representing  the Fund's total return includes  operating
expenses (such as transaction  costs and management  fees) that reduce  returns,

                                GNMA INCOME FUND
                              MANAGEMENT DISCUSSION
                with Casey Colton and Dave Schroeder, Co-Managers

NOTE:  The terms  marked  with an  asterisk  (*) are  defined in the  Investment
Fundamentals section (pages 14-18).

Q:       How did the Fund perform?

A:       The Fund managed a strong performance in comparison with its peers. For
         the year ended  September 30, 1996,  the Fund's total return was 5.06%,
         compared to the 4.45%  average  total  return for its peers in Lipper's
         "GNMA Funds" category.  Based on this total return,  the Fund placed in
         the top 25% of its  category.  For the six months ended  September  30,
         1996, the Fund posted a 2.45% return.

         The Fund's  longer-term  performance has been even stronger compared to
         its peers. For example,  the Fund's average annual total return for the
         three-year  period,  in which the Fund  finished  in the top 20% of its
         category.  (See  the  Lipper  Performance  Comparison  on  page  10 for
         comparisons of the Fund's one-,  three-,  five- and 10-year  returns to
         the returns of the Fund's peer group average.)

Q:       Why did the Fund perform well relative to its peers?

A:       The Fund's relatively  conservative  positioning  compared with many of
         the funds in its Lipper category was the primary reason.  Our main goal
         is to  provide  investors  with  a  fund  that  offers  relative  price
         stability  and  competitive  yields.  This strategy is intended to help
         generate  relatively  predictable returns without interest rate bets or
         unpleasant surprises.

Q:       The  Fund's  duration*  remained  fairly  close to its  benchmark  (the
         Salomon  Brothers  30-Year GNMA Index)  throughout the period.  Is this
         typical?

A:       Yes.  Our goal is to stay within a tight range  around the  duration of
         the Fund's  benchmark.  As a result,  the Fund's  duration never varied
         more than 5% from the duration of its benchmark  throughout the period.
         This was a slightly  shorter  position  than most of the Fund's  peers,
         many of which started the period slightly long but gradually moved to a
         duration  position  more  closely  aligned with the index by the end of
         September.   Our  disciplined  approach  helped  the  Fund  provide  an
         index-like   return,   representing   the  mainstream   performance  of
         mortgage-backed securities.

                              MANAGEMENT DISCUSSION
                       (Continued from the previous page)

Q:       Did you make any adjustments to the Fund's  Treasury  holdings over the
         last six months?

A:       Yes.  At the  start  of the  six-month  period,  most  of the  Treasury
         securities  we  held  in  the  Fund's  portfolio  were  STRIPS.*  These
         securities  perform  well when the yield curve* is moving from steep to
         flat,  while  mortgage-backed  securities  perform  best when the yield
         curve is moving from flat to steep. Including some STRIPS in the Fund's
         portfolio allowed us to enhance the Fund's total return as the shape of
         the yield curve changed in anticipation of possible Fed policy changes.

         Once interest rates  stabilized,  we sold the STRIPS in favor of three-
         and 10-year  Treasury  notes.  We purchased  these  securities  to help
         maintain the Fund's  duration when interest rates began moving lower in
         early September.  In a declining  interest rate  environment,  Treasury
         notes hold their durations,  while mortgage-backed  securities shorten,
         providing smaller incremental returns for each drop in interest rates.

Q:       What are your plans for the Fund over the next six months?

A:       Although  interest rates have trended lower recently because of the low
         inflation  outlook,  there is still  some  uncertainty  concerning  the
         strength  of the  economy  and the  longer-term  direction  of interest
         rates. As a result, we will likely maintain the Fund's neutral position
         going forward unless the outlook for mortgage-backed securities changes
         dramatically.  If the bond market continues to rally, we may add to the
         Fund's  holdings  of  Treasury  notes to offset the erosion of duration
         that  mortgage-backed  securities  typically  experience  when interest
         rates  decline.  In addition,  we will continue to manage the Fund with
         the intent of providing competitive long-term returns.

                             INVESTMENT FUNDAMENTALS
                             MORTGAGE PASS-THROUGHS

Most mortgage-backed securities (which represent ownership interests in pools of
mortgage loans) are structured as pass-throughs.  Pass-throughs are created when
a group of  mortgages  is pooled to back a  security.  The  monthly  payments of
principal  and interest on the  mortgages in the pool are  collected by the bank
that  securitized  the  mortgages and "passed  through" to investors.  While the
payments of principal  and interest  are  considered  secure (many are backed by
government  agencies that guarantee  interest and principal  payments whether or
not borrowers make their  scheduled  mortgage  payments),  the cash flow is less
certain than in other fixed-income  investments.  If a homeowner sells the house
or refinances and pays off the mortgage early, this prepayment is distributed to
investors on a pro rata basis, reducing future interest payments.

The vast  majority of mortgage  pass-throughs  are issued or  guaranteed by U.S.
government-sponsored enterprises (GSEs), including the Federal National Mortgage
Association (FNMA or Fannie Mae), the Federal Home Loan Mortgage Corp. (FHLMC or
Freddie Mac) and the Government  National  Mortgage  Association (GNMA or Ginnie
Mae). GSEs are financing  entities created by Congress for two purposes:  (1) to
allow banks to sell and securitize their loans without concerns about liquidity,
and (2) to ensure that certain  groups of borrowers,  such as  homeowners,  have
sufficient funds to borrow at affordable rates.

Adjustable-Rate Mortgage (ARM) Pass-Throughs

An ARM is a pass-through backed by a pool of adjustable-rate  mortgages.  Unlike
traditional  bonds or  fixed-rate  pass-throughs  (such  as  GNMAs),  ARMs  have
interest  rates that reset  periodically  based on an  underlying  interest rate
index (such as a bank interest  rate).  If market  interest rates rise, then ARM
interest rates also eventually rise, limiting the price fluctuation of ARMs.

However, there is always a lag between market interest rate changes and ARM rate
resets. ARMs reset monthly, quarterly, semiannually or annually based on a money
market or bank interest rate index, such as:

CMT (Constant Maturity Treasury) Index--based on the average yield of a range of
Treasury securities with various fixed maturities.

COFI  (Cost  of Funds  Index)--reflects  the cost of  funds  for  savings  banks
(typically published by the 11th District Federal Home Loan Bank).

LIBOR  (London  Interbank  Offered  Rate)--the  interest  rate at which the most
creditworthy international banks make large loans to one another.

In addition to the lag factor,  ARM rate resets may also be  restrained  by caps
(interest  rate  maximums) and floors  (interest  rate  minimums) that limit the
extent of ARM rate changes.  ARMs can have periodic caps and floors and lifetime
caps and floors. A periodic cap or floor limits how much an ARM's interest rate

                                       14

                       (Continued from the previous page)

can reset in a relatively short time, such as six months or a year. For example,
some ARMs have  periodic  caps of 1% per year,  which means that their  interest
rates can't reset by more than 1% per year,  no matter how high market  interest
rates rise. By contrast,  a lifetime cap limits how high an ARM's  interest rate
can rise in its entire lifetime.  When an ARM reaches its cap because of rapidly
rising interest rates (known as "capping out"), it mimics a fixed-rate security,
and its price becomes less stable.

GNMA Pass-Throughs

A GNMA is a pass-through issued by the Government National Mortgage Association,
a U.S.  government  agency.  Unlike  an  ARM,  a GNMA  is  backed  by a pool  of
fixed-rate mortgages.  A GNMA is also backed by the full faith and credit of the
U.S.  government as to the timely payment of interest and principal.  This means
GNMA  investors  will  receive  their share of interest and  principal  payments
whether or not borrowers make their scheduled mortgage payments. GNMAs typically
have higher yields than U.S. Treasury securities.

Collateralized Mortgage Obligations (CMOs)

A collateralized  mortgage  obligation  (CMO) is a generic mortgage  derivative.
Mortgage  derivatives are usually  securities  created  (derived) from a pool of
mortgages  or mortgage  pass-throughs.  Whereas a  pass-through  is an ownership
interest in a complete  mortgage  pool, a derivative is typically an interest in
just one part of a pool.

Typically, each CMO is a set of two or more classes of securities with different
yields,  maturities and cash flow patterns.  The purpose of a CMO is to take the
cash  flow  from a  mortgage  pool and  reallocate  it in ways  that  appeal  to
different types of investors.  For example,  an interest-only (IO) security is a
CMO that  provides an ownership  interest in just the interest  payments  from a
mortgage pool. The ability to restructure cash flows makes it possible to create
CMOs that are less risky than  traditional  securities  as well as CMOs that are
more risky than  traditional  securities.  CMO risk also  depends on the issuer.
While CMO collateral is typically  issued by GNMA, FNMA or FHLMC, the CMO itself
may be issued by a private party,  such as a brokerage firm, that is not covered
by government guarantees.

The GNMA Fund is permitted to buy CMOs collateralized by GNMA pass-throughs, but
it does not own any  currently  and has no plans to do so. The ARM Fund owns CMO
floaters,   which  are  technically   derivatives  but  behave  very  much  like
traditional  securities.  Like  an  ARM,  the  interest  rate  on a CMO  floater
typically resets monthly to a specific interest rate index.

                       PORTFOLIO SENSITIVITY MEASUREMENTS

Duration

Duration  measures  the price  sensitivity  of a bond or bond fund to changes in
interest rates.  Specifically,  duration  represents the approximate  percentage
change in the price of a bond or bond fund if interest  rates move up or down by
100 basis points  (defined on page 18). For example,  as of September  30, 1996,
the ARM Fund's  duration  was one year,  while the GNMA Fund's  duration was 4.3
years. If interest rates were to fall by 100 basis points (e.g., from 7% to 6%),
the ARM Fund's share price would be expected to increase by 1.0%, while the GNMA
Fund's share price would increase by 4.3%. Conversely, if interest rates were to
rise by 100 basis points (e.g., from 7% to 8%), the ARM Fund's share price would
be expected to decline by 1.0%,  while the GNMA Fund's share price would decline
by 4.3%.

As this example illustrates, the longer the duration, the more bond or bond fund
prices  will move in response to interest  rate  changes.  Therefore,  portfolio
managers  generally lengthen durations when interest rates fall (to maximize the
effects of bond price increases) and shorten  durations when interest rates rise
(to  minimize  the  effects of bond price  declines),  taking  into  account the
investment objectives of the portfolio.

Average Maturity and Average Life

For most bond funds,  average  maturity is another  measurement  of the interest
rate  sensitivity of a bond  portfolio.  Average  maturity  measures the average
amount of time that will pass until the securities in the portfolio mature.  The
longer a  portfolio's  average  maturity,  the more  interest  rate exposure and
interest  rate  sensitivity  it has.  For example,  a portfolio  with a ten-year
average maturity has much more potential  exposure to interest rate changes than
a portfolio with a one-year average maturity.

Whereas  most bonds  return the entire  principal  at  maturity,  ARMs and GNMAs
provide  gradual  payments of principal  throughout  their  lives.  As a result,
comparing the average maturity of ARM and GNMA funds to other bond funds is like
comparing  apples to oranges.  A more accurate measure for ARM and GNMA funds is
the average life of a fund's portfolio. The average life includes only principal
payments and weights each payment  equally.  An ARM or GNMA fund with an average
life of ten years has approximately the same interest rate sensitivity as a bond
fund with an average maturity of ten years.

                             INVESTMENT FUNDAMENTALS
                                  RISK FACTORS

ARM and GNMA funds are essentially  high-yielding  short- and  intermediate-term
bond funds. They should not be placed in the same category as money market funds
or long-term  bond funds.  ARM and GNMA funds  typically  pay higher yields than
money  market  funds  because  they do not attempt to maintain a constant  share
price. They also typically pay higher yields than Treasury funds with comparable
maturities  because mortgage  pass-throughs  tend to underperform  when interest
rates rise or fall sharply.  Over time,  the higher yields on ARM and GNMA funds
tend to compensate investors for the following mortgage-related risks:

Prepayments--when   interest  rates  fall,   mortgage  rates  also  fall,  which
encourages homeowners to refinance (or "prepay") their mortgages to reduce their
monthly payments. Although prepayments are good for homeowners,  they're bad for
ARM and GNMA investors,  who purchase a pass-through expecting it to exist for a
certain number of years.  Prepayments  shorten the lives of mortgage  portfolios
and force ARM and GNMA investors to reinvest in  lower-yielding  mortgage pools.
Therefore,   when  prepayment  levels  climb,  mortgage  analysts  increase  the
prepayment  assumptions used to price pass-throughs.  As a result,  pass-through
durations shorten,  while Treasuries benefit from longer durations when interest
rates fall.

Duration  Extension--when  interest  rates rise sharply,  higher  interest rates
reduce prepayments, which is good, but the lower level of prepayments causes ARM
and GNMA durations to extend,  which is bad when rates are rising.  Pass-through
portfolios  become more  susceptible  to price  declines at a time when  greater
price stability would be desirable.  By contrast,  Treasury durations  generally
shorten when interest rates experience a large increase.

Yield Curve

The yield curve is a graphic representation of the relationship between risk and
return  for  fixed-income  securities.   Yield  curve  graphs  plot  lengthening
maturities  along the horizontal axis and rising yields along the vertical axis.
Most "normal"  yield curves start in the lower left corner of the graph and rise
to the upper right corner,  indicating that yields rise as maturities  lengthen.
This   upward   sloping   yield   curve   illustrates   a   normal   risk/return
relationship--more return (yield) for more risk (a longer maturity). Conversely,
a "flat" yield curve provides little or no extra return for taking on more risk.

Other Security Types

Fixed-Rates--mortgage pass-throughs backed by fixed-rate mortgages.

Repos--repurchase  agreements  backed by securities with government  guarantees.
These are very short-term securities used as cash equivalents.

Treasury Notes--intermediate-term Treasury securities.

Treasury  STRIPS--zero-coupon bonds issued by the U.S. Treasury. Unlike ordinary
Treasury securities,  which pay interest periodically,  zero-coupon bonds pay no
interest.  Instead,  these  securities  are issued at a deep  discount  and then
redeemed for their full face value at maturity.

Portfolio Statistics

Market Value--the market value of a fund's investments on a given date.

Number of Issues--the number of different securities issuances held by a fund on
a given date.

Average  Coupon--a  weighted  average of all  interest  coupons held in a fund's
portfolio.

Average  Maturity--a  weighted  average  of  all  bond  maturities  in a  fund's
portfolio (see also page 16).

Average  Life--a  weighted  average  of the  "life"  of each  bond  in a  fund's
portfolio (see also page 16).

Average Duration--a weighted average of all bond durations in a fund's portfolio
(see also page 16).

Investment Terms

Basis Points--a basis point equals one  one-hundredth  of a percentage point (or
0.01%). Therefore, 100 basis points equals one percentage point (or 1%).

Coupon--the stated interest rate of a security.

Premium and Discount Bonds

If a bond's  interest  coupon  is  higher  than  prevailing  rates,  the bond is
considered to be a premium bond. If the coupon is lower than  prevailing  rates,
the bond is considered to be a discount bond. Premium pass-throughs tend to have
more  price   stability  than  discount   pass-throughs--premium   pass-throughs
depreciate less when interest rates rise, but they appreciate less when interest
rates  fall.  Discount   pass-throughs   behave  more  like  long-term  Treasury
securities.

NOTES TO FINANCIAL STATEMENTS
September 30, 1996
(Unaudited)

(1)   ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Benham Government Income Trust (BGIT) is registered under the Investment Company
Act of 1940 as an open-end management  investment  company.  BGIT is composed of
six funds, including the Benham Adjustable Rate Government Securities Fund (ARM)
and Benham GNMA Income Fund (GNMA). The ARM Fund invests primarily in adjustable
rate mortgage  securities  issued or  guaranteed  by the U.S.  government or its
agencies   or   instrumentalities.   The  GNMA   Fund   invests   primarily   in
mortgage-backed GNMA certificates. The following significant accounting policies
are in accordance with accounting  policies generally accepted in the investment
company industries.

Security  Valuations--Securities  held by the Funds are valued at current market
value as provided by an independent  commercial pricing service. When valuations
are not readily available,  securities are valued at fair value as determined in
good faith by or under the direction of the Board of Trustees.

Security  Transactions--Security  transactions  are  accounted  for on the  date
purchased  or  sold.  Net  realized  gains  and  losses  are  determined  on the
identified cost basis, which is also used for federal income tax purposes.

Income  Tax  Status--It  is the  policy  of the  Funds  to  distribute  all  net
investment  income  and  net  realized  capital  gains  to  shareholders  and to
otherwise qualify as a regulated  investment company under the provisions of the
Internal  Revenue Code.  Accordingly,  no provision has been made for federal or
state taxes.

Distributions  to  Shareholders--Net  investment  income  dividends are declared
daily and distributed monthly. Net realized gains in excess of available capital
loss  carryovers  will be distributed  each December.  As of March 31, 1996, the
accumulated  net realized  capital loss  carryover  of  $69,205,630  for ARM and
$23,041,420  for GNMA  (expiring 2000 through 2004) may be used to offset future
taxable gains.

The character of distributions  made during the year from net investment  income
or net  realized  gains may differ  from  their  ultimate  characterization  for
federal income tax purposes due to differences in the  recognition of income and
expense items for financial statement and tax purposes.

                                       25

Use of  Estimates--The  preparation of financial  statements in conformity  with
generally accepted  accounting  principles requires management to make estimates
and assumptions  that affect the reported  amounts of assets and liabilities and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements and the reported  amounts of increase and decrease in net assets from
operations during the period. Actual results could differ from these estimates.

Forward  Commitments--The  Funds may  purchase  and sell  some  U.S.  government
securities on a firm commitment basis. Under these arrangements, the securities'
prices and  yields  are fixed on the date of the  commitment,  but  payment  and
delivery are scheduled  for a future date.  During this period,  securities  are
subject  to  market   fluctuations.   The  Funds  maintain  segregated  accounts
consisting of cash or high quality  securities  in an amount  sufficient to meet
the purchase price.

(2)   INVESTMENT ADVISORY FEES AND OTHER TRANSACTIONS WITH AFFILIATES

Benham  Management  Corporation  (BMC) is a wholly owned subsidiary of Twentieth
Century Companies,  Inc. (TCC). Each Fund pays BMC a monthly investment advisory
fee based on its pro rata  share of the  dollar  amount  derived  from  applying
BGIT's average daily net assets to the following annualized  investment advisory
fee schedule.

         .50% of the first $100 million
         .45% of the next $100 million
         .40% of the next $100 million
         .35% of the next $100 million
         .30% of the next $100 million
         .25% of the next $1 billion
         .24% of the next $1 billion
         .23% of the next $1 billion
         .22% of the next $1 billion
         .21% of the next $1 billion
         .20% of the next $1 billion
         .19% of net assets over $6.5 billion

BMC provides BGIT with all investment advice.  Twentieth Century Services,  Inc.
(TCS) pays all  compensation  of BGIT  officers and trustees who are officers or
directors  of  TCC  or  any of its  subsidiaries.  In  addition,  promotion  and
distribution expenses are paid by BMC.

BGIT has an  Administrative  Services and Transfer Agency  Agreement with TCS, a
wholly owned subsidiary of TCC. Under the agreement,  TCS provides substantially
all  administrative  and transfer agency services necessary to operate each Fund
of BGIT. Fees for these

                                       26

services  are based on  transaction  volume,  number of accounts and average net
assets of all funds in The Benham Group.  The agreement was formerly with Benham
Financial Services, Inc.

BGIT has an additional  agreement  with BMC pursuant to which BMC  established a
contractual  expense  guarantee  that  limits each  Fund's  expenses  (excluding
expenses such as brokerage  commissions,  taxes,  interest,  custodian  earnings
credits,  and  extraordinary  expenses)  to .60% (.65% prior to June 1, 1996) of
average daily net assets.  The agreement  provides that BMC may recover  amounts
(representing  expenses in excess of the Fund's expense guarantee rate) absorbed
during the 11 preceding  months if, and to the extent that, for any given month,
the Fund's expenses were less than the expense  guarantee rate in effect at that
time. The expense rate is subject to renewal in June 1997.

The  payables  to  affiliates  as of  September  30,  1996,  based on the  above
agreements were as follows:

                                                 ARM Fund        GNMA Fund

                                                 ========       ========

BGIT has a distribution agreement with Twentieth Century Securities, Inc., which

(5)   EXPENSE OFFSET ARRANGEMENTS

Each Fund's Statement of Operations  reflects custodian earnings credits.  These
amounts  are  used to  offset  the  custody  fees  payable  by the  Funds to the
custodian  bank.  The credits  are earned  when the Fund  maintains a balance of
uninvested cash at the custodian bank.  Beginning with the year ending March 31,
1996,  the ratios of expenses to average daily net assets shown in the Financial
Highlights   are   calculated   as  if  these   credits  had  not  been  earned.

* Certificates are subject to principal paydowns as a result of prepayments or refinancing of the underlying  mortgage  instruments.
As a result,  the  actual  life of a pool may be  substantially  less than the life of the  original  underlying  mortgages  and the
indicated maturity.
** Cost for federal income tax purposes is presented in Note 4 to the accompanying financial statements.
(1)The coupons on these securities reset frequently  (monthly or quarterly) and are not restricted by low periodic or lifetime caps,
so their price volatility is similar to Adjustable Rate Mortgage Securities.

See the accompanying notes to the financial statements.
