The fixed-income  markets faced a steady headwind  throughout most of the fiscal
year. Initially,  that headwind came in the form of robust U.S. economic growth,
rising long-term interest rates and inflation fears,  creating an environment in
which investors favored stocks over bonds.

Later on, the winds  shifted  slightly,  although not to the benefit of the bond
market.  Continued  above-trend growth in the U.S.,  improving global economies,
tight labor markets and price increases in commodities stirred up concerns about
rising   inflation.   In  turn,  the  U.S.  Federal  Reserve  reacted  with  two
quarter-point  increases in short-term  interest  rates,  which pushed most bond
prices lower, particularly those of longer-dated, rate-sensitive securities such
as Treasuries.

However,  because  high-yield  corporate  securities  pay  a  wide  spread  over
Treasuries,   they  were  able  to  withstand  the  pressure  of  rising  rates.
Nonetheless, this area of the market faced various other challenges. At midyear,
an urgency to meet  corporate  financing  needs ahead of  potential  Y2K-related
market disruptions created a flood of new high-yield  issuance.  Meanwhile,  Y2K
concerns  somewhat  suppressed demand for these bonds as investors reduced their
high-yield   inventories   and  carried  higher  cash  balances  into  year-end.
Individual security selection consequently became more crucial than ever, and we
narrowed  our focus to only the  highest-quality,  most  liquid  securities  the
market had to offer.

This strategy also served us well in the investment-grade  sector. While many of
these bonds reacted with some volatility to the changes in monetary policy,  our
success in identifying  companies with higher-rated debt that are enjoying rapid
earnings growth aided the performance of several of our funds.  Furthermore,  as
the spread, or difference in yield,  between corporates and Treasuries  widened,
so did the buying opportunity for investment-grade  corporates.  To that end, we
put our  company-by-company  research approach to work and uncovered a number of
opportunities  we believe  offer  tremendous  value yet to be  recognized by the
market.

Recently,  signs  that U.S.  economic  growth may be  moderating  have led us to
conclude that the overall bond market should soon return to more normal  levels.
However,  I remind you that in good and bad economies  alike,  great  investment
opportunities still exist. Finding those opportunities is what we're all about.

In  closing,  I'd like to comment on one of several  steps we're  taking  toward
positioning  Janus for  success  well  into the  future.  On  January  1,  2000,
portfolio  manager Jim Craig will become full-time chief investment  officer and
director of research,  overseeing  the ongoing  strengthening  of our collective
security-selection  process.  In his expanded  role,  Jim will focus intently on
analyst training and mentoring while continuing to monitor investment management
decisions  across every fund we manage.  I'm very excited about this advancement
now that every Janus shareholder will more directly benefit from Jim's extensive
experience and talent.

Thank you for your continued confidence and investment with Janus.

portfolio manager

Janus Flexible  Income Fund returned 1.75% for the fiscal year ended October 31,
1999,  compared with (0.66%) for the Lehman Brothers  Government/Corporate  Bond
Index.(1)

It's been a challenging 12 months for  fixed-income  markets,  especially  given
that the Federal Reserve not only cut short-term interest rates at the beginning
of the year,  but also  raised  them twice  toward the end of it.  However,  the
Fund's  flexible  investment  approach  enabled us to respond to these  changing
market conditions, delivering positive results by year-end.

Overall,  we played our cards more  carefully  during the  period,  raising  the
Fund's  cash  position  and  taking  steps to lower  its  sensitivity  to rising
interest  rates.  Because  Treasury  bonds are most  vulnerable to interest rate
pressures,  we reduced our weighting in this area by more than half, to 9.5%. At
the same time, we increased our weighting in  investment-grade  corporate  debt,
focusing on bonds with  intermediate  maturities.  We also  upgraded  the credit
quality of our  investment-grade  holdings,  adding  positions in  well-financed
companies such as Wal-Mart, IBM and Ford Motor Company.

As far as the high-yield market goes, we maintained a conservative  approach due
to the  fact  that  bonds  in this  area  were  dealing  with  uncertainty  over
Y2K-related  market liquidity fears and competition from high-flying  technology
stocks.  This strategy proved successful,  and we were rewarded for our focus on
large,  well-financed  issuers  that  were  able  to  withstand  broader  market
pressures.

Additionally, we used the market's volatility to add select high-yield positions
in companies we felt were  underappreciated  by the market. In identifying these
credits,  we benefited  from our own hands-on  research as well as from insights
shared by our equity research team. Two newer positions that  contributed to our
performance  were  PSINet and Qwest  Communications.  Internet  provider  PSINet
continues to gain new  corporate  clients with its reliable,  low-cost  service.
Meanwhile,   long-distance   carrier  Qwest  just   completed  its   18,500-mile
state-of-the-art  fiber-optic  network  and  continues  to grow its revenue at a
rapid  pace,   supported  by  high  demand  for  its  Internet  connections  and
fiber-optic  services.  Our Qwest bonds also benefited from the company's recent
acquisition of US West, a former Baby Bell company and a higher-rated credit.

We were also pleased  with the  performance  of several of our pay-TV  holdings,
including  Charter   Communications,   Galaxy,  RCN  and  Pegasus  Media.  These
high-yield  bonds were less  volatile  and more  liquid  during the year as they
benefited from stable cash flows, the increasing penetration of premium services
such as  pay-per-view  and  digital  cable,  as well as  growing  telephony  and
Internet  auxiliary  revenues.  RCN was also aided by a large equity  investment
made by Microsoft cofounder Paul Allen's Vulcan Ventures.

Consolidation  in the  supermarket  industry worked in our favor when two of our
larger positions, Fred Meyer and Star Markets, were acquired by companies with

higher credit ratings,  effectively  upgrading the quality of our holdings.  Our
supermarket  holdings offer us strong U.S.-based cash flows and generous yields,
and  they  are  guided  by  managers  who know  the  importance  of  maintaining
investment-grade ratings.

Moderating  our  returns was  sluggish  performance  by our reduced  position in
Treasury bonds, which, under the weight of rising interest rates,  suffered from
declining  prices  and  increasing  yields.  In  fact,  year-over-year,  30-year
Treasury bond yields rose nearly 1%. Another  disappointment  was our high-yield
position  in  Tokheim,  a  manufacturer  of gas pumps.  The  company's  revenues
declined  when  several  global oil  companies  delayed  their orders to Tokheim
following internal consolidation issues at the company, and we consequently sold
the position.

Looking ahead, we're encouraged by recent signs of a moderation in U.S. economic
growth.  While we're  confident that the pressure on  fixed-income  markets will
ease once interest rates stabilize,  we also believe this challenging market can
work in our  favor,  providing  us with  opportunities  to put our cash to work.
Consequently,  we'll remain on the lookout for credits that offer solid interest
income as well as the potential for stable or appreciating prices.

In  closing,  we'd  like to thank  you for your  continued  investment  in Janus
Flexible Income Fund.

6  Janus Income Funds / October 31, 1999
<PAGE>

                                                         Janus | High-Yield Fund

                                                                         [PHOTO]
                                                                 Sandy Rufenacht
                                                               portfolio manager

For the fiscal year ended  October 31,  1999,  Janus  High-Yield  Fund  returned
6.34%,  outperforming  the 4.34%  gain by our  benchmark,  the  Lehman  Brothers
High-Yield Bond Index. (1)

This past year has been a challenging one for bond  investors.  The situation in
the emerging markets remains  uncertain,  stock prices have been turbulent,  and
renewed  inflation  fears  have put  interest  rates  back on an  upward  track.
Uncertainty  also remains over how investors will respond to the approaching Y2K
transition.  Nonetheless,  because  high-yield  bonds  pay a  wide  spread  over
Treasury bond rates, they were able to withstand the pressure of rising interest
rates and outperformed the rest of the fixed-income universe.

However, some worrisome trends surfaced. For example, default rates edged higher
throughout  the year,  although they remained low by historical  standards.  The
market was also  flooded with new supply as  corporations  rushed to bring their
bond  issues  to  market  in an effort  to meet  their  financing  needs  before
year-end.  At the same time,  liquidity was a problem as investors began selling
their bond  inventory to boost their cash  holdings.  With this  combination  of
oversupply and shrinking demand,  prices slumped and differences  between yields
widened.

Against  this  backdrop,  we decided  to take some chips off the table  while we
waited for  interest  rates to  stabilize,  the stock  market to settle down and
Y2K-related market uncertainty to pass.

Consequently,  we raised the Fund's cash  position  and shifted more assets into
higher-grade corporate debt. Unfortunately,  this strategy somewhat hindered our
results.  Higher-quality,  lower-yielding bonds are typically more vulnerable to
rising  interest rates,  and our increased  weighting in this area of the market
detracted  from our  performance.  Even so,  because  our first  priority  is to
safeguard  our  investors'  assets,  especially  in a turbulent  market,  we are
confident we made the right decision.

Another  measure we took to insulate the Fund while meeting current income needs
was to raise our weighting in  yield-to-call  bonds. An example is our long-time
position in Price  Communications,  a cellular telephone service provider in the
Southeast.  The company is  improving  its cash flow,  which leads us to believe
there is a good chance it will  refinance its debt and call in these bonds.  The
market  apparently  agrees,  and the bonds trade very close to their call price.
Until they are retired, however, we will continue to clip a nice coupon payment,
confident these bonds will maintain their value.

We were  also  pleased  with the  performance  of Isle of  Capri,  a  casino  in
Blackhawk,  Colorado. The management of the casino is using cash flow in all the
right ways - reinvesting in the business and paying down debt. Recently, Isle of
Capri  purchased  Lady Luck Casino,  another  holding in the Fund and one of our
strongest  performers  this year. Isle of Capri has announced it will retire the
Lady Luck high-yield debt at par, benefiting our position.

Our new  position  in  Exodus  Communications  also  contributed  to the  Fund's
performance.  Exodus provides corporations with secure facilities where they can
house their corporate Web servers.  The company has been adding new customers at
a rapid rate and saw revenues  quadruple in the third quarter.  This  investment
allows us to  participate  in the growth of networking  and  e-commerce  without
subjecting the Fund to the volatility of pure Internet investments.

While we were satisfied with our overall results,  we were disappointed with the
performance  of Hard Rock Hotel in Las Vegas.  The bonds  traded  lower  after a
recent hotel  expansion  temporarily  hurt casino  traffic and gaming  revenues.
Although we were  concerned  with this misstep,  we were confident the expansion
would ultimately bring more revenue to the casino.  Our confidence was bolstered
when Hard  Rock's  owner  invested  $28  million of his own money in the form of
preferred  stock.  We held on to the position  and are pleased by early  figures
that show the business is back on track.

Going forward,  we will continue to look for  opportunities to put our cash back
to  work,   concentrating  on  high-quality,   yield-to-call   bonds  issued  by
well-managed companies with solid U.S.-based cash flows. As always, we will rely
on our own hands-on  research and intensive  analysis to seek out  opportunities
others might have missed.

In closing, I'd like to thank you for investing in Janus High-Yield Fund.

Past  performance  does not  guarantee  future  results.  Investment  return and
principal value will fluctuate so that shares, when redeemed,  may be worth more
or less than their original cost. All returns reflect reinvested dividends.  The
Fund's portfolio may differ  significantly from the securities in the Index. The
Index is  unmanaged  and  therefore  does  not  reflect  the  cost of  portfolio
management or trading.

has been the  financial  recovery  in Asia.  This time  last  year,  when  these
economies appeared to be in a downward spiral, many foreign investors sought the
safe haven of U.S.  Treasury bonds. The resulting inflow of capital drove prices
higher and kept  interest  rates low.  But as markets in the Far East started to
recover  earlier  this year,  foreign  investors  pulled  their  money from U.S.
Treasuries  and went in search of higher yields abroad.  Consequently,  the U.S.
Treasury  market slumped,  and the 30-year  Treasury bond rate started to climb,
yielding 6.16% at fiscal year-end.

Renewed  inflation  fears also added to the pressure on interest  rates, as U.S.
economic growth  remained  strong and tight labor markets  continued to drive up
wage costs.  Responding  to the threat of an  overheating  economy,  the Federal
Reserve raised  short-term  interest rates twice this summer.  Policymakers also
signaled that at least one more rate hike was likely by year-end unless signs of
a slowing economy became apparent.

Overall,  the volatility in fund flows and uncertainty  over interest rates kept
fixed-income  markets  under  pressure this year.  In this  investment  climate,
maintaining  safety of  principal  was our number  one  concern.  That said,  we
concentrated  on higher-rated  issues while keeping the Fund's average  duration
close to that of its index.  Unfortunately,  these more  liquid,  higher-quality
bonds became sensitive to rising interest rates and lost ground,  thus hindering
our performance.

We also  saw  weakness  in the  healthcare  and  hospital  bond  market  and are
vigilantly  monitoring  our  positions  in Boulder  Hospital  Revenue and Denver
Health Services.  Healthcare bonds in general have struggled recently because of
industry-wide concerns over government regulation and insurance  reimbursements.
Fortunately,  our  exposure to this area of the  tax-exempt  market was limited.
Because we know our credits well,  though,  we're confident they will provide us
with solid  long-term  performance,  regardless  of what  happens in the broader
healthcare market.

The Fund's relative  performance was enhanced by our holdings in  higher-coupon,
lower-rated  bonds,  which were less sensitive to rising interest rates. Most of
these credits are  concentrated  in the Rocky  Mountain  region,  allowing us to
visit them regularly and employ the hands-on  research for which Janus is known.
Within this area, we identified  several  opportunities we believe are currently
undervalued by the market and offer us the potential for price  appreciation  as
well as higher-coupon payments.

One position that worked well for us was Douglas County  Nebraska Zoo.  Revenues
and cash flow at the zoo have been very strong,  supported by  attendance at its
new world-class  feline exhibit.  Consequently,  we think there is a good chance
the zoo will call these bonds in the near future. In the meantime, these credits
continue to trade in a narrow range around their call price, providing

welcome stability in a choppy market as well as generous interest payments.

We also maintained our exposure to Colorado  double-tax-exempt bonds, which make
up about a third of total Fund assets.  This strategy  allows us to tap into the
state's  strong  economy and ensures a steady  supply of  attractive  investment
opportunities  as  well  as  liquidity  when  shifting  our  positions   becomes
necessary.

One success in this category was our position in Blackhawk gaming bonds. Casinos
in the town of Blackhawk account for 80% of all gaming revenues in Colorado, and
their share is growing.  In fact, casino revenues in Blackhawk are increasing at
a  double-digit  rate during a time when revenues in the national  gaming market
are slowing.  We also like this position because we can drive up to Blackhawk in
an  afternoon,  check on the  traffic  at the  casinos  and  spot any  potential
problems.

At this writing,  Asian economies look stronger, and the U.S. economy is showing
few signs of  slowing,  leading us to  believe  interest  rates may move  higher
before  they  stabilize.  In  this  climate,  we  will  concentrate  on  finding
high-quality bonds with higher-than-current-market  coupons that will enable the
Fund to better absorb any future interest rate increases.

In closing,  I would like to thank you for your  continued  investment  in Janus
Federal Tax-Exempt Fund.

Janus | Short-Term Bond Fund

[PHOTO]
Sandy Rufenacht
portfolio manager

For the 12-month  period  ended  October 31, 1999,  Janus  Short-Term  Bond Fund
returned   2.82%,   while  its   benchmark,   the  Lehman   Brothers   1-3  Year
Government/Corporate Bond Index, gained 3.20%. (1)

As Tom Bailey points out in his letter, the past year has been a challenging one
for  fixed-income  markets.  Long-term  interest rates were rising,  the Federal
Reserve took a more  aggressive  stance to slow the economy,  and  international
economic recoveries remained fragile.

In this volatile environment, we were aided by our flexible investment approach,
which helped us respond quickly to changing market dynamics.  We kept the Fund's
average  maturity  in line with its  benchmark  to balance the threat of Federal
Reserve  rate hikes  against  the  prospect  of  increased  year-end  demand for
high-quality,  short-term  paper.  We also  remained  selective in our choice of
investments,  focusing on issuers with sound business plans, solid domestic cash
flows and  limited  exposure  to  international  markets.  Consequently,  stable
investment-grade  names such as  Wal-Mart  and Ford  continued  to be  prominent
holdings.

Additionally,  we benefited  from the credit  improvement  of select telecom and
media bonds in the investment-grade  area, which offset the downward pressure on
the broader fixed-income market. Standouts included telecommunications giant MCI
WorldCom and cable service provider Cox Communications.

Our  holdings  in  high-yielding  corporate  securities  also  aided the  Fund's
performance.  The wider spreads,  or difference in yields,  on these instruments
provided a cushion against rising  interest  rates,  while their higher interest
payments  bolstered  our  total  income.   These  positions  were  primarily  in
yield-to-call  bonds,  which trade close to their call price  because  investors
anticipate  they will be retired  in the near  future.  While  they have  little
potential for price  appreciation,  these bonds offer a low-risk investment that
also pays a healthy coupon.

For  example,  Host  Marriott  Travel  Plaza,  a former  subsidiary  of Marriott
Corporation that operates food and drink concessions at travel and entertainment
venues,  was a yield-to-call  position that worked in our favor. The company was
recently  purchased by Autogrill,  part of Italy's  Bennetton  group,  which has
announced  plans to pay off the  bonds  earlier  than  anticipated.  Until  this
happens,  we will  continue  to  clip a  generous  coupon.  Nextel,  a  wireless
telecommunications provider, is another name that we expect to be retired early.
These bonds were underwritten with multiple  restrictions that the company would
like to be free of going  forward.  We expect  that they  will be  retired  at a
premium in the near future.

HEALTHSOUTH is another  position worth  mentioning.  This bond was upgraded from
high-yield  to  investment-grade  status  during  the  period,  which  helped it
continue a long run of success for us.

However,  it  recently  declined  along with the rest of the  healthcare  sector
because of uncertainty over insurance  reimbursements  and changes in government
regulations.   While  we  believe   this   well-capitalized   company  has  been
misunderstood by the market, we felt the volatility associated with these issues
was too risky for our investors, so we elected to liquidate our position.

Looking ahead, we believe the threat of additional  interest rate increases will
keep the short-term bond market on edge. In this  environment,  we will approach
the markets with a conservative posture, continuing to focus on safeguarding the
underlying   value  of  the  Fund's  assets  while  investing  in  higher-coupon
securities to meet current income needs.  Our strategy will also involve keeping
the  Fund's  duration  close  to  that of our  benchmark  until  interest  rates
stabilize.

In  closing,  I'd  like to  thank  you for your  continued  investment  in Janus
Short-Term Bond Fund.

Past  performance  does not  guarantee  future  results.  Investment  return and
principal value will fluctuate so that shares, when redeemed,  may be worth more
or less than their original cost. All returns reflect reinvested dividends.  The
Fund's portfolio may differ  significantly from the securities in the Index. The
Index is  unmanaged  and  therefore  does  not  reflect  the  cost of  portfolio

Janus Government
Money Market Fund

For the fiscal year ended October 31, 1999,  Janus Money Market Fund ranked 74th
out of 332 funds in the U.S. Money Market Category as tracked by Lipper, Inc., a
leading mutual fund rating company.(1) Janus Government Money Market Fund ranked
30th out of 122 funds in the U.S.  Government  Money Market  category during the
same  period,(2) and Janus  Tax-Exempt  Money Market Fund ranked 15th out of 132
funds in the U.S. Tax-Exempt Money Market category. (3)

With the global economic  situation  stabilizing,  the major factor  influencing
money  markets  this year was the threat of higher U.S.  interest  rates.  While
consumer price  increases have remained  muted,  there are some worrisome  signs
that higher inflation could be on the horizon. For example,  tight labor markets
have put upward pressure on wage costs,  and the dollar's  weakness  relative to
the Japanese yen has made some imported goods more expensive.  Furthermore, with
prices of oil and other raw materials  rising,  some  producers may be forced to
pass along  higher  costs to their  retail  customers.  These  concerns  led the
Federal Reserve Board to shift away from its stimulative policy stance of a year
ago,  when  it  cut  overnight  interest  rates  three  times,  embarking  on an
aggressive campaign to temper economic growth and head off inflation.
Consequently,  the central bank raised interest rates twice this summer and left
open the prospect of additional rate hikes going forward.

While short-term money markets were relatively calm during the first half of the
year,  uncertainty  over the timing and severity of additional Fed interest rate
increases  has recently  kept markets on edge.  Currently,  yields in short-term
money  markets  reflect a widely held view that central bank  policymakers  will
raise  rates  another 25 basis  points in  November.  But the risk is that rates
could move even  higher if the Fed does not see  concrete  signs the  economy is
slowing.

The  approaching  Y2K  transition  is also  adding to money  market  volatility.
Typically,  we  anticipate a temporary  spike in interest  rates at the end of a
calendar year. That's because corporations and individuals temporarily rearrange
their  assets to suit  different  investor  needs.  This  year,  however,  these
year-end  dislocations  are  expected  to be even  greater  because of  investor
uncertainty  over the widely discussed  millennium date change.  We believe this
Y2K effect will be  short-lived,  without any  significant  or lasting affect on
financial markets. The Federal Reserve has also assured investors it will supply
whatever  liquidity is  necessary  to keep market  functions as normal as can be
expected at the end of any year.

Nonetheless,  we have added to our cash  holdings to help  cushion the Fund from
any unusual  volatility.  The year-end turbulence is expected to be most evident
in the taxable money markets,  which are more sensitive to the threat of Federal
Reserve  policy  changes.  The  impact  will  likely be less  pronounced  in the
tax-exempt  money  market,   which  should   experience  more  typical  year-end
volatility.

We also believe these Y2K-related market dislocations will create  opportunities
to add yield for our  shareholders.  For  example,  we are already  seeing money
market securities with mid-January maturities paying substantially higher yields
than money market  instruments with mid-December  maturities.  The difference in
yields is much wider than we typically see, even at year-end.  Consequently,  we
have  extended  the  maturity  of some  of our  short-term  investments  to take
advantage of this.

Looking ahead,  we are confident that our higher cash position will help cushion
performance  from  the  risk of  higher  interest  rates,  while  giving  us the
flexibility to respond to changing market conditions.

In closing,  we'd like to thank you for your continued investment in Janus Money

Repurchase  Agreements  held  by a  fund  are  fully  collateralized,  and  such
collateral  is in the  possession  of the fund's  custodian.  The  collateral is
evaluated  daily to ensure its market value exceeds the current  market value of
the repurchase  agreements,  including accrued interest. In the event of default
on the  obligation  to  repurchase,  the fund has the  right  to  liquidate  the
collateral  and apply the proceeds in  satisfaction  of the  obligation.  In the
event of default or bankruptcy by the other party to the agreement,  realization
and/or  retention  of the  collateral  or  proceeds  may  be  subject  to  legal
proceedings.

                                                 Notes to | Financial Statements

The following  section  describes the  organization  and significant  accounting
policies of the Funds and provides more detailed information about the schedules
and tables that appear  throughout this report.  In addition,  the Notes explain
how the Funds  operate and the methods used in  preparing  and  presenting  this
report.

1.   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     Janus  Investment  Fund (the  "Trust") is registered  under the  Investment
     Company  Act of 1940 (the  "1940  Act") as a no-load,  open-end  management
     investment  company.  Four series of shares (the "Bond Funds")  included in
     this report  invest  primarily in  income-producing  securities,  and three
     series  of  shares  (the  "Money  Market  Funds")  invest   exclusively  in
     high-quality  money  market  instruments.  Each of the Money  Market  Funds
     offers three classes of shares.

     "Investor Shares" are available to the general public,  and  "Institutional
     Shares" are available only to investors that meet certain  minimum  account
     sizes.  "Service  Shares" are available  through banks and other  financial
     institutions.

     The following policies have been consistently followed by the Funds and are
     in  conformity  with  accounting   principles  generally  accepted  in  the
     investment company industry.

     INVESTMENT VALUATION
     Securities  are  valued at the  closing  price for  securities  traded on a
     principal  exchange  (U.S. or foreign) and on the NASDAQ  National  Market.
     Securities  traded on  over-the-counter  markets and listed  securities for
     which no sales are  reported  are  valued at the latest bid price (or yield
     equivalent  thereof)  obtained from one or more dealers making a market for
     such  securities or by a pricing service  approved by the Funds'  Trustees.
     Short-term  investments  maturing within 60 days for the Bond Funds and all
     money market  securities  in the Money Market Funds are valued at amortized
     cost, which approximates market value.  Foreign securities are converted to
     U.S.  dollars  using  exchange  rates at the  close  of the New York  Stock
     Exchange. When market quotations are not readily available,  securities are
     valued at fair value as determined in good faith by the Funds' Trustees.

     INVESTMENT TRANSACTIONS AND INVESTMENT INCOME
     Investment transactions are accounted for as of the date purchased or sold.
     Dividend income is recorded on the ex-dividend date. Certain dividends from
     foreign securities will be recorded as soon as the Trust is informed of the
     dividend if such  information  is obtained  subsequent  to the  ex-dividend
     date.  Interest  income is  recorded  on the  accrual  basis  and  includes
     amortization of discounts and premiums.  Gains and losses are determined on
     the identified cost basis,  which is the same basis used for federal income
     tax purposes.

     FORWARD TRANSACTIONS AND FUTURES CONTRACTS
     The Bond Funds may enter into forward currency contracts in order to reduce
     their  exposure  to  changes in foreign  currency  exchange  rates on their
     foreign  portfolio  holdings  and to lock in the U.S.  dollar  cost of firm
     purchase  and  sale  commitments  for  securities  denominated  in  foreign
     currencies. A forward currency contract is a commitment to purchase or sell
     a foreign  currency at a future date at a negotiated rate. The gain or loss
     arising from the  difference  between the U.S.  dollar cost of the original
     contract and the value of the foreign currency in U.S. dollars upon closing
     of such  contract  is  included  in net  realized  gain or loss on  foreign
     currency transactions.

     Forward currency  contracts held by the Funds are fully  collateralized  by
     other  securities,  which  are  denoted  in the  accompanying  Schedule  of
     Investments.  Such collateral is in the possession of the Fund's custodian.
     The  collateral  is  evaluated  daily to ensure its market  value equals or
     exceeds the current  market  value of the  corresponding  forward  currency
     contracts.

     Currency gain and loss are also calculated on payables and receivables that
     are  denominated in foreign  currencies.  The payables and  receivables are
     generally related to security transactions and income.

     Futures  contracts are marked to market daily,  and the variation margin is
     recorded  as an  unrealized  gain or loss.  When a contract  is  closed,  a
     realized  gain or loss is  recorded  equal to the  difference  between  the
     opening and closing  value of the  contract.  Generally,  open  forward and
     futures  contracts are marked to market for federal  income tax purposes at
     fiscal year-end.

     Foreign-denominated  assets and forward currency contracts may involve more
     risks than domestic  transactions,  including currency risk,  political and
     economic risk,  regulatory  risk and market risk.  Risks may arise from the
     potential  inability of a counterparty to meet the terms  of a contract and
     from unanticipated movements in the value of foreign currencies relative to
     the U.S. dollar.

     The Bond  Funds  may  enter  into  "futures  contracts"  and  "options"  on
     securities,  financial indexes,  foreign currencies,  forward contracts and
     interest rate swaps and swap-related products. The Bond Funds intend to use
     such  derivative  instruments  primarily  to hedge or protect  from adverse
     movements in securities  prices,  currency rates or interest rates. The use
     of futures  contracts and options may involve risks such as the possibility
     of  illiquid  markets or  imperfect  correlation  between  the value of the
     contracts and the underlying securities, or that the counterparty will fail
     to perform its obligations.

     Swap  Spread  Lock  Agreements  are  marked  to  market  daily  based  upon
     quotations  from  market  makers and the  change,  if any,  is  recorded as
     unrealized gains or

                                       Janus Income Funds / October 31, 1999  43

Notes to | Financial Statements (continued)

     losses in the Statements of  Operations.  An amount of cash or other liquid
     assets having an aggregate net asset value at least equal to the unrealized
     gains or losses will be  maintained  in a segregated  account by the Funds'
     custodian.   Janus  Capital  will  monitor  the   creditworthiness  of  all
     counterparties  on an  ongoing  basis.  If there is a default  by the other
     party to such a transaction, a Fund will have contractual remedies pursuant
     to the agreements related to the transaction.

     ADDITIONAL INVESTMENT RISK
     Janus  High-Yield  Fund and Janus  Flexible  Income Fund may be invested in
     lower-rated  debt  securities that have a higher risk of default or loss of
     value because of changes in the economy or in their respective industry.

     DIVIDEND DISTRIBUTIONS AND EXPENSES
     Dividends are declared daily and distributed monthly.  Each Bond Fund bears
     expenses  incurred  specifically  on its  behalf  as well as a  portion  of
     general expenses.

     FEDERAL INCOME TAXES
     The Funds  intend to  distribute  to  shareholders  all taxable  investment
     income and realized  gains and otherwise  comply with the Internal  Revenue
     Code applicable to regulated investment  companies.  Of the ordinary income
     distributions  declared for the year ended October 31, 1999,  97% and 100%,
     respectively,  were  exempt from  federal  income  taxes for Janus  Federal
     Tax-Exempt Fund and Janus Tax-Exempt Money Market Fund.

     ESTIMATES
     The  preparation  of financial  statements  in  conformity  with  generally
     accepted  accounting  principles  requires management to make estimates and
     assumptions  that affect the reported  amount of assets and liabilities and
     disclosure  of  contingent  assets  and  liabilities  at  the  date  of the
     financial statements and the reported amounts of income and expenses during
     the reporting period. Actual results could differ from those estimates.

2.   INVESTMENT ADVISORY AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES

     The advisory agreements with the Bond Funds describe the fee that the Funds
     must pay. Each of the Bond Funds are subject to the following schedule:

                             Average
                             Daily Net            Annual Rate     Expense Limit

- --------------------------------------------------------------------------------
*    Janus  Capital will waive  certain fees and expenses to the extent that net
     expenses exceed the stated limits.

     Each of the Money Market Funds pays Janus Capital .20% of average daily net
     assets as an investment  advisory  fee.  Janus Capital has agreed to reduce
     its  advisory  fee for each of the Janus  Money  Market  Funds to .10%.  In
     addition, each class of shares of each Money Market Fund pays Janus Capital
     an  administrative  fee. This fee is .50%,  .15%, and .40% of average daily
     net assets for the  Investor  Shares,  Institutional  Shares,  and  Service
     Shares, respectively. Janus Capital has agreed to reduce the administrative
     fee to .05%  and  .30% on the  Institutional  Shares  and  Service  Shares,
     respectively.  All other expenses of the Money Market Funds except Trustees
     fees and  expenses,  audit  fees and  interest  expenses  are paid by Janus
     Capital.

     Janus Service Corporation  ("Janus Service"),  a wholly owned subsidiary of
     Janus  Capital,  receives  an annual fee of 0.16% of average net assets per
     fund plus $4.00 per  shareholder  account  from each Bond Fund for transfer
     agent services plus reimbursement of certain out-of-pocket expenses.

     Officers  and  certain  trustees  of the  Funds  are also  officers  and/or
     directors of Janus Capital;  however, they receive no compensation from the
     Funds.

     DST Systems,  Inc. (DST), an affiliate of Janus Capital through a degree of
     common  ownership,  provides fund  accounting  and  shareholder  accounting
     systems to the Funds through Janus Capital and Janus Service.  Fees paid to
     DST for the period ended October 31, 1999, are noted below.

3.   FEDERAL INCOME TAX

     The Funds  have  elected  to treat  gains and  losses on  forward  currency
     contracts as capital  gains and losses.  Other foreign  currency  gains and
     losses on debt  instruments  are  treated as  ordinary  income for  federal
     income tax purposes pursuant to Section 988 of the Internal Revenue Code.

     Net  capital  loss  carryovers  noted  below as of October  31,  1999,  are
     available to offset future realized capital gains and thereby reduce future
     taxable gains  distributions.  These carryovers  expire between October 31,
     2002,  and October 31, 2007.  The  aggregate  cost of  investments  and the
     composition  of  unrealized  appreciation  and  depreciation  of investment
     securities  for federal  income tax  purposes as of October 31,  1999,  are
     listed  below.  The federal tax cost for the Money Market Funds is the same
     as listed in the Statement of Assets and Liabilities.

     Net investment  income  distributions  and capital gains  distributions are
     determined in accordance with income tax regulations, which may differ from
     generally  accepted  accounting  principles.  These  differences are due to
     differing  treatments  for items such as deferral  of wash  sales,  foreign
     currency transactions, net operating losses and capital loss carryforwards.
     Permanent items  identified in the period ended October 31, 1999, have been

Explanation of | Charts and Tables

1.   PERFORMANCE OVERVIEWS

     Performance  overview  graphs on the previous pages compare the performance
     of a $10,000 investment in each Fund (from inception) to one or more widely
     used market indexes through October 31, 1999.

     When comparing the  performance of a Fund with an index,  keep in mind that
     market indexes do not include brokerage  commissions that would be incurred
     if you purchased the individual  securities in the index.  They also do not
     include  taxes  payable on dividends  and  interest or  operating  expenses
     incurred if you maintained a portfolio invested in the index.

     Average annual total returns are also quoted for each Fund.  Average annual
     total return is  calculated  by taking the growth or decline in value of an
     investment over a period of time,  including  reinvestment of dividends and
     distributions,  then calculating the annual compounded percentage rate that
     would have  produced  the same result had the rate of growth been  constant
     throughout the period.

2.   SCHEDULES OF INVESTMENTS

     Following  the  performance  overview  section is each  Fund's  Schedule of
     Investments. This schedule reports the industry concentrations and types of
     securities  held in each Fund's  portfolio on the last day of the reporting
     period.  Securities  are usually  listed by type (common  stock,  corporate
     bonds, U.S. government  obligations,  etc.) and by industry  classification
     (banking, communications, insurance, etc.).

     The  market  value of each  security  is  quoted  as of the last day of the
     reporting period. The value of securities denominated in foreign currencies
     is converted into U.S. dollars.

2A.  FORWARD CURRENCY CONTRACTS

     A table listing forward currency  contracts follows each Fund's Schedule of
     Investments (if applicable).  Forward currency  contracts are agreements to
     deliver or receive a preset  amount of currency at a future  date.  Forward
     currency  contracts are used to hedge against foreign  currency risk in the
     Fund's long-term holdings.

     The table provides the name of the foreign currency, the settlement date of
     the contract, the amount of the contract, the value of the currency in U.S.
     dollars and the amount of unrealized gain or loss. The amount of unrealized
     gain or loss reflects the change in currency  exchange  rates from the time
     the contract was opened to the last day of the reporting period.

3.   STATEMENT OF OPERATIONS

     This  statement  details the Funds' income,  expenses,  gains and losses on
     securities and currency  transactions,  and appreciation or depreciation of
     current portfolio holdings.

     The first section in this statement,  entitled "Investment Income," reports
     the dividends earned from stocks  and interest earned from interest-bearing
     securities in the portfolio.

     The next section reports the expenses and expense  offsets  incurred by the
     Funds, including the advisory fee paid to the investment advisor,  transfer
     agent fees,  shareholder  servicing expenses,  and printing and postage for
     mailing statements, financial reports and prospectuses.

     The last section  lists the increase or decrease in the value of securities
     held in the  Funds'  portfolios.  Funds  realize a gain (or loss) when they
     sell their position in a particular security.  An unrealized gain (or loss)
     refers to the  change in net  appreciation  or  depreciation  of the Funds'
     portfolios during the period.  "Net Gain/(Loss) on Investments" is affected
     both by changes in the market value of portfolio  holdings and by gains (or
     losses) realized during the reporting period.

4.   STATEMENT OF ASSETS AND LIABILITIES

     This  statement is often  referred to as the "balance  sheet." It lists the
     assets  and  liabilities  of the  Funds on the  last  day of the  reporting
     period.

     The Funds'  assets  are  calculated  by adding the value of the  securities
     owned,  the  receivable  for  securities  sold  but  not yet  settled,  the
     receivable for dividends  declared but not yet received on stocks owned and
     the receivable  for Fund shares sold to investors but not yet settled.  The
     Funds'  liabilities  include payables for securities  purchased but not yet
     settled,  Fund shares  redeemed but not yet paid and expenses  owed but not
     yet paid.  Additionally,  there may be other assets and liabilities such as
     forward currency contracts.

     The last line of this  statement  reports  the Funds' net asset value (NAV)
     per share on the last day of the reporting period. The NAV is calculated by
     dividing the Funds' net assets (assets minus  liabilities) by the number of
     shares outstanding.

5.   STATEMENT OF CHANGES IN NET ASSETS

     This  statement  reports the  increase or decrease in the Funds' net assets
     during  the  reporting  period.  Changes  in  the  Funds'  net  assets  are
     attributable to investment operations, dividends, distributions and capital
     share transactions. This is important to investors because it shows exactly
     what caused the Funds' net asset size to change during the period.

     The  first  section  summarizes  the  information  from  the  Statement  of
     Operations regarding changes in net assets because of the Funds' investment
     performance.  The Funds' net assets may also change as a result of dividend
     and capital gains  distributions to investors.  If investors  receive their
     dividends in cash, money is taken out of the Fund to pay the  distribution.
     If investors  reinvest their  dividends,  the Funds' net assets will not be
     affected.  If you compare  each Fund's "Net  Decrease  from  Dividends  and
     Distributions"  to the  "Reinvested  dividends and  distributions,"  you'll
     notice that  dividend  distributions  had little  effect on each Fund's net
     assets.  This is because the  majority of Janus  investors  reinvest  their
     distributions.

     The   reinvestment   of  dividends  is  included   under   "Capital   Share
     Transactions." "Capital Shares" refers to the money investors contribute to
     the Funds  through  purchases or withdraw via  redemptions.  The Fund's net
     assets will increase and decrease in value as investors purchase and redeem
     shares from the Fund.

     The section  entitled "Net Assets Consist of" breaks down the components of
     the Funds' net assets.  Because  Funds must  distribute  substantially  all
     earnings,  you'll  notice  that a  significant  portion  of net  assets  is
     shareholder capital.

6.   FINANCIAL HIGHLIGHTS

     This schedule provides a per-share  breakdown of the components that affect
     the Funds' net asset value (NAV) for  current and past  reporting  periods.
     Not only does this table  provide you with total  return,  it also  reports
     total  distributions,  asset size,  expense  ratios and portfolio  turnover
     rate.

     The  first  line in the  table  reflects  the  Funds'  NAV per share at the
     beginning  of the  reporting  period.  The next line reports the Funds' net
     investment income per share, which comprises  dividends and interest income
     earned on  securities  held by the Funds.  Following is the total of gains,
     realized and unrealized. Dividends and distributions are then subtracted to
     arrive at the NAV per share at the end of the period.

     Also  included are the Funds'  expense  ratios,  or the  percentage  of net
     assets that was used to cover operating expenses during the period. Expense
     ratios  vary  across  the  Funds  for a number of  reasons,  including  the
     differences  in management  fees,  average  shareholder  account size,  the
     frequency of dividend payments and the extent of foreign investments, which
     entail greater transaction costs.

     The Funds' expenses may be reduced through expense-reduction  arrangements.
     These  arrangements  include the use of brokerage  commissions,  uninvested
     cash  balances  earning  interest  or balance  credits.  The  Statement  of
     Operations  reflects total expenses  before any such offset,  the amount of
     offset and the net  expenses.  The expense  ratios  listed in the Financial
     Highlights  reflect  total  expenses  both prior to any expense  offset and
     after the offsets.

     The ratio of net investment  income summarizes the income earned divided by
     the average net assets of a Fund during the reporting period. Don't confuse
     this ratio with a Fund's yield.  The net  investment  income ratio is not a
     true  measure of a Fund's  yield  because it doesn't  take into account the
     dividends distributed to the Fund's investors.

     The next ratio is the portfolio  turnover  rate,  which measures the buying
     and  selling  activity  in the Funds'  portfolios.  Portfolio  turnover  is
     affected by market conditions, changes in the size of a fund, the nature of
     the Fund's investments and the investment style of the portfolio manager. A
     100% rate implies that an amount equal to the value of the entire portfolio
     is turned  over in a year;  a 50% rate  means  that an amount  equal to the
     value of half the portfolio is traded in a year; and a 200% rate means that
     an amount equal to the value of the portfolio is sold every six months.

To the Trustees and Shareholders of
Janus Investment Fund

In our opinion, the accompanying statements of assets and liabilities, including
the schedules of  investments,  and the related  statements of operations and of
changes  in net assets  and the  financial  highlights  present  fairly,  in all
material  respects,  the financial position of Janus Flexible Income Fund, Janus
High-Yield  Fund,  Janus Federal  Tax-Exempt  Fund,  Janus Short-Term Bond Fund,
Janus  Money  Market  Fund,  Janus  Government  Money  Market  Fund,  and  Janus
Tax-Exempt  Money Market Fund (seven of the  portfolios  constituting  the Janus
Investment Fund,  hereafter referred to as the "Funds") at October 31, 1999, and
the results of each of their  operations for the year then ended, the changes in
each of their net assets for each of the two years in the period  then ended and
the financial  highlights for each of the periods indicated,  in conformity with
generally  accepted  accounting  principles.   These  financial  statements  and
financial highlights  (hereafter referred to as "financial  statements") are the
responsibility  of the Funds'  management;  our  responsibility is to express an
opinion on these  financial  statements  based on our audits.  We conducted  our
audits of these  financial  statements in  accordance  with  generally  accepted
auditing  standards,  which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the  amounts  and  disclosures  in  the  financial  statements,   assessing  the
accounting  principles  used and significant  estimates made by management,  and
evaluating the overall  financial  statement  presentation.  We believe that our
audits,  which  included  confirmation  of  securities  at October  31,  1999 by
correspondence  with the custodians and brokers,  provide a reasonable basis for
the opinion expressed above.

Preparing  for  Year  2000 is a high  priority  for  Janus  Capital,  which  has
established a dedicated  group to address this issue.  Janus Capital has devoted
considerable  internal  resources and has engaged one of the foremost experts in
the field to help achieve Year 2000 readiness. Janus Capital does not anticipate
that Year  2000-related  issues  will have a material  impact on its  ability to
continue to provide the Funds with  service at current  levels;  however,  Janus
Capital  cannot make any  assurances  that the steps it has taken to ensure Year
2000 readiness will be successful.  In addition,  there can be no assurance that
Year 2000  issues  will not affect the  companies  in which the Funds  invest or
worldwide markets and economies.
