Throughout  the first half of the fiscal  year,  low  interest  rates and benign
inflation  continued to fuel economic  expansion both in the U.S. and in Europe,
creating  a  healthy  environment  for  corporate  fundamentals.  As  production
capacity surged and  unemployment  dropped,  equities in these markets  advanced
considerably, with many reaching all-time highs.

Asia,  however,  was  an  altogether  different  story.  Fears  surrounding  the
Continent's  economic  malaise  subsided early in the period but resurfaced when
Japan slipped into a recession at midyear.  Nonetheless, the Japanese government
continued  to react  somewhat  impassively  toward  getting its economy  back on
track,  raising concerns about corporate  profits,  which then heightened global
volatility.

In August, other developing economies began to "catch" the Asian flu. Russia was
one of the first to be affected,  and its  financial  breakdown  created fear of
further  turmoil  in  Brazil,  Argentina  and  other  emerging  markets.  Stocks
worldwide  declined  sharply on these  negative  developments,  regardless  of a
company's size or strength.

Leading these  downturns  were  financial  services  companies  with exposure to
developing countries.  This created somewhat of a liquidity shortage in the U.S.
banking  system and, as large parts of the credit  markets  began to dry up, the
likelihood of a credit crunch  increased.  While the tightness in credit markets
became  severe,  it was relieved by the strong action of the Federal  Reserve to
reduce interest rates. When the Fed unexpectedly cut rates a second time, people
believed Fed Chairman Alan  Greenspan was willing to do whatever it took to ease
credit problems.

Meanwhile,  the domestic  economy  remained  relatively  favorable with consumer
spending strong, housing investments proceeding at a healthy clip, and virtually
no sign of inflation. In fact, near the end of the period, the U.S. stock market
regained some of its lost ground, and the earlier flight to the highest-quality,
most liquid investments became less pronounced.

Looking  ahead,  I believe the  eight-year  growth spurt our economy has enjoyed
will slow in tandem with  economies  worldwide.  But, as our portfolio  managers
will tell you in their  letters,  even in a slow-growth  environment,  there are
always  companies  out  there  that  can  perform  well.  Finding  them  is  the
challenging part.  Although my outlook for corporate  earnings is generally less
positive, I'm confident our time-tested  stock-picking approach will continue to
lead us to dominant  franchise leaders that can grow their earnings,  regardless
of economic movements.

In  conclusion,  I'd like to thank you again for your  continued  investment  in
Janus funds.

/s/ Tom

James P. Craig
portfolio manager

Janus Fund finished the 12-month period ended October 31, 1998, with a return of
15.12%  compared  to  the  S&P  500  Index,   which  gained  22.01%.(1)  Despite
underperforming  its index,  the Fund earned a first-quartile  ranking,  placing
44th  out of  240  capital  appreciation  funds  tracked  by  Lipper  Analytical
Services, Inc., a mutual fund rating company.(2)

During the first six months of the year, low interest  rates,  benign  inflation
and  steady  corporate  earnings  propelled  the stock  market  to new  heights.
Throughout  this  period,  I continued to increase the Fund's focus on companies
with  sustainable  earnings  growth,  believing  the  days  of easy  gains  from
excessive  P/E-multiple  expansion were  numbered.  As it turned out, those days
ended during the latter part of the period when fallout from the Asian  economic
crisis  began to spread  globally.  The  markets  retreated  following  downward
revisions in earnings estimates for companies with exposure to emerging markets.

In addition,  the collapse of Russia's economy and Brazil's  subsequent currency
slide  heightened  concerns for countries  dependent on foreign  capital.  These
events also created panic in the markets as investors began to  indiscriminately
sell stocks based on the fear that emerging market  breakdowns  would ultimately
drag the U.S. into a recession.

However,  I  stayed  focused  through  this  nervousness  and  stuck to my guns,
investing only in strong franchises I believe can grow earnings across a variety
of economic  conditions.  In fact,  stock  sell-offs  sparked by global concerns
actually presented some great buying opportunities. As a result, I increased our
positions in companies that are somewhat less sensitive to economic  events,  as
well as high-growth industries undergoing dynamic changes, including technology,
pharmaceutical and cable companies.

Throughout  most of the period,  steady PC sales and explosive  Internet  growth
drove  selected  technology  stocks,  with  Dell  Computer,  Cisco  Systems  and
Microsoft posting solid gains for the Fund. We remain optimistic about prospects
for  these  companies  based on  their  solid  business  models,  rapid  product
development  and high  earnings  growth -  characteristics  that  have  thus far
enabled them to successfully manage the effects of economic turmoil.

The Fund's  pharmaceutical  stocks also held up well. Several of these companies
benefited from breakthroughs in drug therapies.  Sales for Viagra, Pfizer's male
impotence  treatment,  were brisk upon its  introduction.  And  Warner-Lambert's
Lipitor,  a  cholesterol-lowering  drug, and Rezulin,  a treatment for diabetes,
both gained considerable market share throughout the year.

After a  relatively  flat  first  half,  our  cable  stocks  rallied  on news of
Tele-Communications,  Inc.'s  (TCI's)  acquisition  by AT&T.  This merger helped
validate our theory about the cable  industry:  that new,  value-added  services
such as  telephony,  data and  video-on-demand  (all  offered  through  existing
operating platforms) will generate significant addi-

(1)  All returns include reinvested dividends.

(2)  A capital appreciation fund is defined as one that "aims at maximum capital
     appreciation,  frequently  by  means  of 100% or more  portfolio  turnover,
     leveraging,  purchasing unregistered  securities,  purchasing options, etc.
     The fund may take large cash positions." As of October 31, 1998, Janus Fund
     ranked 28/96 of capital  appreciation  funds for the 5-year period and 5/55
     for the 10-year  period.  The ranking is based on total  return,  including
     reinvestment of dividends and capital gains for the stated period.

tional  cash  flow,  which can be used to  enhance  shareholder  value for these
companies.  I believe our  positions in TCI,  Time Warner,  Comcast and MediaOne
Group all stand to benefit.

Of course, the Fund was not without disappointments. Oil prices collapsed during
the first half of the year,  and I  liquidated  our holdings in the oil services
industry at cost.  Our financial  services  stocks were also bruised,  primarily
because  of loans and hedge  fund  investments  in  struggling  emerging  market
economies.  These included  BankAmerica  and UBS, both of which were  eliminated
from the Fund at a loss.

Another  stock that took an especially  hard hit was  Parametric  Technology,  a
software  developer in  computer-aided  design and  manufacturing.  Parametric's
earnings fell short of estimates as  management  lost sight of its core business
during the  introduction of a new product.  We ended up liquidating the position
at a loss.

Looking  ahead,  I don't believe a recession is in our immediate  future.  I do,
however,  anticipate a slowdown in economic  growth.  The  combination of slower
growth and moderate  inflation should keep long-term interest rates low. In this
less exuberant environment, I believe companies that can meet or exceed earnings
estimates will be rewarded.  These are precisely the type of companies I plan to
stay focused on.

Thank you for investing in Janus Fund.

Janus | Balanced Fund

[PHOTO]
Blaine P. Rollins
portfolio manager

For the fiscal year ended October 31, 1998,  Janus Balanced Fund returned 15.48%
while the  Standard & Poor's  500 Index  gained  22.01% and the Lehman  Brothers
Government/Corporate Bond Index gained 10.28%.(1) I'm pleased to report that the
Fund placed 35th out of 395 balanced funds (top 9%) ranked by Lipper  Analytical
Services, Inc., a mutual fund rating company.(2)

While  the past  year has been a  difficult  one for many  investors,  the Janus
research  team has  excelled at  uncovering  the best  investment  opportunities
available for the Fund. Without the team's tireless efforts, including countless
hours and  miles on the road  researching  our  companies  - their  managements,
competitors, suppliers and customers - the gains we've achieved simply would not
have been possible.

Despite increased market volatility and a slowing economy late in the period, my
investment  strategy remained focused.  The Fund, as always, is constructed on a
bottom-up  basis,  security by  security,  and  includes  equities,  convertible
stocks,  as well as fixed-income  instruments of the best companies we can find.
Characteristics  we look for in our companies  include top-line  growth,  strong
earnings growth potential,  improving returns on capital, growing free cash flow
generation, and managements that reinvest their cash back into their companies.

Looking back, we had many successes  during the year,  particularly  among cable
companies.  Janus'  exceptional  work in this area allowed us to get in early on
some great ones,  such as Time Warner  (via the Houston  Industries  convertible
preferred stock), Comcast, Tele-Communications,  Inc. and MediaOne Group. It has
become  clearer  during the past year that the  value-added  revenue  streams of
digital cable,  cable  telephony and cable Internet modem services are likely to
accelerate the free cash flow generation of these  companies.  As a result,  our
common  stocks and  convertible  stocks in this area have become big winners for
the Fund.

We were also able to find investments in smaller, privately held cable operators
through high-yield fixed-income  investments.  Not only can the rising cash flow
streams of these operators help them repay debt more quickly, but the increasing
values of all cable assets should also enable them to access the equity  markets
and become investment grade rated sooner than expected.

When many companies in the S&P 500 Index began to confront earnings difficulties
and  investors  focused  only on those  with  the  strongest  earnings  streams,
pharmaceutical  stocks benefited.  Our investments in Warner-Lambert  and Pfizer
performed extremely well (up 66% and 53%, respectively, for the year) as several
of their high-profile  treatments took center stage and drove earnings growth to
among the highest in the industry.

My pick for CEO of the year,  John Chambers,  continued to lead Cisco Systems on
its torrid pace of  developing  the best hardware for the  networking  industry.
Under Mr. Chambers' leadership,  Cisco grew its revenues 31% and earnings 33% in
the 12 months ended July 31, 1998. The news should only get better as the voice,
video and data markets  continue to converge,  boosting demand for the equipment
necessary to carry out these functions.

(1)  All returns include reinvested dividends.

(2)  A balanced fund is defined by Lipper as "a fund whose primary  objective is
     to conserve  principal by  maintaining at all times a balanced fund of both
     stocks and bonds. Typically the stock/bond ratio ranges around 60%/40%." As
     of October  31,  1998,  Janus  Balanced  Fund  ranked  9/150 for the 5-year
     period.  Lipper's ranking is based on total return,  including reinvestment
     of dividends and capital gains for the stated period.

Past performance does not guarantee future results.

On the traditional  fixed-income side, a concentrated  weighting in intermediate
maturity U.S. Treasury and corporate bonds also helped our performance. The Fund
benefited from the fall in the U.S.  Treasury 10-year yield,  which dropped from
5.8% to 4.6%.  With low  growth  in world  economies,  nonexistent  inflationary
pressures and the U.S. government now running the budget at a surplus,  interest
rates could head lower, further lifting the prices of our 7-10 year bonds.

Amid the  successes,  there were also  disappointments.  Our  financial  stocks,
namely  Household  International  and  BankAmerica,  were hurt by credit  issues
related to economic  pressures  in  emerging  markets.  Earnings  at  Parametric
Technology fell short of expectations  when a new product  introduction  shifted
management's  attention  away from its core business.  And despite  threats of a
global economic slowdown late in the period which punished our holdings in Royal
Caribbean Cruises and Carnival Corporation,  business fundamentals appear firmly
in place for both.  Increasingly  affordable  cruise vacations  continue to take
share from land-based  vacations.  As newer,  more profitable ships are added to
their fleets, we look for these companies' margins,  returns on capital and cash
flow generation to improve.

I could go on,  but I'll sum it all up by saying  1998 was a great year for many
of our companies, and I expect many others to exceed our own high projections in
1999.

Thank you for your continued investment in Janus Balanced 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 | Enterprise Fund

{PHOTO]
James P. Goff
portfolio manager

For the fiscal year ended  October 31,  1998,  Janus  Enterprise  Fund  returned
11.79%  compared  to a 6.71% gain  posted by its  benchmark,  the S&P MidCap 400
Index.(1)  These gains placed the Fund 14th out of 302 mid-cap  funds tracked by
Lipper  Analytical  Services,  Inc., a mutual fund rating company,  earning it a
top-quartile ranking.(2)

During the period,  small- and mid-cap stocks continued to linger in the shadows
of their larger  counterparts.  The liquidity and  perceived  safety  offered by
large caps averted investors' attention from the fact that earnings growth among
smaller  companies has, in recent  quarters,  outpaced that of the larger names.
However, investors' enthusiasm for all stocks was curbed late in the period as a
result of a slowdown in worldwide  economic  growth  caused by the spread of the
"Asian  Contagion."  Effects from Asia's economic breakdown not only found their
way into Russia and Brazil, but were also felt throughout Europe and the U.S.

This global turmoil substantially  compressed earnings growth for U.S. companies
of all shapes and sizes, particularly those with exposure to emerging economies.
Even so, my objective has always been to find companies that can write their own
script,  where the economy and competitors are mere background  noise. I believe
we've been  successful  on this  front.  As  corporate  profits  across  America
weakened,  the earnings  growth among our companies grew an average of 30%. That
said, we're particularly excited about opportunities in education and technology
- - areas that aided the Fund's performance.

A rise in compensation  for college  graduates  versus high school graduates has
driven an increase in demand for college degrees among working adults,  which in
turn  boosted  the  earnings  growth of several  of our  education  stocks.  One
standout was Apollo  Group,  which offers  accredited  degree  programs to adult
students  through  subsidiaries  such as the  University  of Phoenix.  I believe
Apollo is uniquely  positioned to gain from these positive trends,  which should
continue to contribute to its strong earnings growth potential.

Turning  to our  technology  holdings,  several  of our  positions  weathered  a
negative  environment,   especially  in  the  semiconductor  industry.   Vitesse
Semiconductor, the Fund's largest holding, appreciated thanks to the substantial
increase in demand from the  telecommunications  and data  communications  areas
that continue to be propelled by Internet  traffic  growth  (currently  doubling
every 100 days). We were also impressed with results posted by Veritas Software,
one of the Fund's newer technology positions and another beneficiary of Internet
growth.  This  company  designs  software  to  help  manage  and  store  data (a
flourishing business, considering the amount of data currently being generated).
In fact,  more data have been  stored in 1998 than in the  previous  five  years
combined. Going forward, I believe Veritas should prosper as the demand for data
storage continues its dramatic rise.

The Fund's performance was also influenced by its substantial weighting in media
stocks, which

(1)  Both returns include reinvested dividends.

(2)  A mid-cap  fund is  defined  by Lipper  as "a fund  that by  prospectus  or
     portfolio   practice   invests   primarily   in   companies   with   market
     capitalizations  less  than $5  billion  at the  time of  purchase."  As of
     October  31,  1998,  Janus  Enterprise  Fund  ranked  31/101 for the 5-year
     period.  The ranking is based on total return,  including  reinvestment  of
     dividends and capital gains for the stated period.

produced  strong results in the first half before being  somewhat  restrained by
concerns of a potential economic recession late in the period.  However, more so
than a strong  economy,  our companies are driven by the  consolidation  of this
industry,  which  benefits their  revenues and expenses.  Therefore,  my outlook
remains   positive   for  our   positions   in   Chancellor   Media,   Univision
Communications, Jacor Communications, and Heftel Broadcasting.

In an attempt  to make the Fund more  recession  proof,  we  liquidated  several
disappointing  cyclical  or  economically  sensitive  growth  stocks,  including
Fastenal,  Littlefuse  and  Barnett.  And despite  impressive  earnings  growth,
Healthcare  Financial  Partners,  a  financing  company for  healthcare  service
providers,  declined on negative perceptions  surrounding most financial-related
companies. Nonetheless, we remain impressed with its solid business fundamentals
and have, in fact, increased our position in the stock.

Despite the volatility that recently rocked the financial  markets, I remind you
that interest  rates and earnings are what  ultimately  drive stock prices.  The
good news for stocks is that interest rates are low and trending lower. Even so,
it's critical  that we continue to uncover  names we believe can triumph  during
good times and bad.  As always,  we're  confident  our  dedication  and  intense
research will lead us to these companies.

Thank you for your investment in Janus Enterprise Fund.

12  Janus Equity Funds / October 31, 1998

For the fiscal year ended  October 31, 1998,  Janus Equity  Income Fund returned
19.21%,  while  the  Standard  & Poor's  500  Index  gained  22.01%.(1)  Despite
underperforming  its  benchmark,  the Fund  achieved  top-quartile  performance,
ranking  10th out of 214  equity  income  funds  tracked  by  Lipper  Analytical
Services, Inc., a mutual fund rating company.(2)

While this has been a difficult year for many  investors,  our research team has
excelled at  uncovering  some of the best  investment  opportunities  out there.
Without the team's tireless efforts,  including spending a great deal of time on
the road researching  companies (their managements,  competitors,  suppliers and
customers), the gains we achieved would not have been possible.

While the  market's  volatility  and  economic  backdrop  has  changed in recent
months,  my  strategy  for  running  the  Fund has not.  I am still  focused  on
achieving the highest  returns  possible with  below-average  volatility,  while
investing  61% of the  portfolio  in  income-producing  securities.  The Fund is
constructed  on a  bottom-up  basis,  security by  security.  It is my intent to
assemble a portfolio  of the best  companies I can find that have the  following
attributes:  top-line growth,  strong earnings  potential,  improving returns on
capital,  growing free cash flow, and managements  that reinvest their cash back
into their companies.

Looking  back  on  our  successes  during  the  year,  we see  many  highlights,
particularly in the cable industry. Janus' exceptional work on cable enabled the
Fund to  invest  early  in  companies  such  as Time  Warner  (via  the  Houston
Industries convertible preferred stock), Comcast, Tele-Communications, Inc., and
MediaOne Group.  Since investing in these companies,  it has become clearer that
new value-added  services including digital cable,  telephony and Internet modem
services will likely accelerate their free cash flow.

Among my favorite cable stocks is Time Warner, a company that  encapsulates many
of the attributes we look for in an ideal investment. To summarize Time Warner's
story in three  quick  terms:  cable,  content  and cash flow.  Not only is this
company   positioned  to  benefit  from  rising  cable  valuations,   but,  more
importantly, from the increasing number of media distribution outlets and demand
for superior  programming  content.  Few companies have either a better existing
library or lineup of current  artists and creators  than Time  Warner.  With its
cable and content  hitting the  fundamentals,  Time Warner  should begin to gush
free cash flow over the next three  years,  which it will likely use to increase
shareholder value by paying down debt and repurchasing stock.

Another highlight was Dell Computer, which continued to exceed all expectations,
posting a 227% gain for the  12-month  period.  Its  direct  model  business  of
desktop,  laptop and server  manufacturing  has quickly set the standard for all
manufacturing industries.  Because it manufactures and ships its products within
hours of taking orders over the Internet, phone or fax, Dell has very little raw
material  or  finished  inventory  needs and thus  produces  returns  on capital
significantly  above its  competitors.  In fact, for the last quarter  reported,
Dell  produced  a return of $2.17 for every  dollar of  invested  capital.  This
incredible  return on invested  capital  has allowed it to generate  substantial
free cash flow and repurchase  nearly 1.5% of its shares  outstanding in each of
the last two quarters.

(1)  Both returns include reinvested dividends.

(2)  An  equity  income  fund  is  defined  by  Lipper  as "a fund  which  seeks
     relatively  high current income and growth of income through  investing 60%
     or more of its portfolio in equities."  Lipper's  ranking is based on total
     return,  including  reinvestment  of  dividends  and capital  gains for the
     stated period.

Past performance does not guarantee future results.

Another  area  that did well for the Fund was  pharmaceuticals.  Beyond  posting
solid gains  during the period,  our  convertible  bond  position in Alza should
continue  to  appreciate  following  the  release of  Ditropan,  its new urinary
incontinence  drug.  Ditropan has proven extremely  effective in clinical trials
and will likely benefit from the growing acceptance of incontinence drugs.

Unfortunately,  not all of our stocks met our  expectations.  Some of the Fund's
media  positions  were  bruised  by  fears  of a  possible  economic  recession,
including  Univision  Communications,  a Spanish TV  broadcasting  company,  and
Heftel Broadcasting, a Spanish-language radio broadcaster. Hispanic advertising,
however, is growing at twice the rate of all ad spending. Therefore, our outlook
for  these  companies  remains  positive,  and we  continue  to hold on to their
stocks.

Our cruise ship  companies,  Royal Caribbean  Cruises and Carnival  Corporation,
also  declined on fears  related to economic  turbulence.  Even so, the business
fundamentals for both companies remain strong.  Going forward,  we look for them
to benefit from the  increasing  popularity  of  cruise-based  vacations,  which
continue to take share away from land-based vacations as a result of the greater
affordability  and higher customer  satisfaction.  Furthermore,  the addition of
newer,  more-profitable ships to these companies' fleets should improve margins,
returns on capital and cash flow generation.

While 1998 was a great year for many of our  companies,  I expect many others to
exceed our own high projections in 1999. As always, your continued investment in
Janus Equity Income Fund is greatly appreciated.

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.

portfolio manager

Your fund  performed  well this past fiscal year,  gaining 16.73% for the period
ended  October 31, 1998.  This placed it 175th out of 726, or in the top 24%, of
all growth and income  funds  tracked by Lipper  Analytical  Services,  Inc.,  a
mutual  fund  rating  company.(2)  While we were  able to  achieve  top-quartile
performance  relative  to our  competitors,  we lagged the return of the S&P 500
Index of 22.01%.(1)

Substantial volatility has marked global capital markets this past year. The S&P
500  Index  moved  30% from its lows to  highs.  So how does  this  impact  your
investment?   Such  volatility   creates  a  very  attractive   environment  for
fundamentally  driven investors like Janus. This is a stock-picker's  market. We
are able to take  advantage  of this  volatility  and  invest  in  well-managed,
high-return  businesses  selling  at  attractive  prices.  We  are  looking  for
companies with significant  growth  opportunities in the next few years that are
not fully appreciated by the market. This strategy emulates Wayne Gretzky's, who
said, "Go to where the puck is going to be, not to where it is."

We  selectively  added to many of our  positions,  especially  in the  cable and
pharmaceutical   areas.   Our   positions  in  Time  Warner,   Comcast  and  Cox
Communications  all posted  exceptional  gains during the year. Let me reiterate
our two main reasons why we maintain our cable investments: network upgrades are
nearing completion, meaning substantial increases in free cash flow, and, at the
same time, new services are garnering  additional revenue.  During recent visits
to  several  cable  firms,  I was able to test these new  value-added  services:
digital tiers,  enhanced video,  faster Internet access,  cheaper phone service,
all  channeled  into the  household  through  a single  cable  wire.  We  remain
optimistic about the prospects for cable, as corporate leaders such as Microsoft
and AT&T continue to invest in the industry.

Strong product  pipelines,  high returns on capital and declining interest rates
have  also  lead our  pharmaceutical  stocks  to  outperform.  Pfizer  remains a
standout in this group as it is the  marketing  partner of choice in the sector.
We believe the stock can continue to gain ground on optimism  surrounding  a new
arthritis drug known as Celebrex,  which it co-markets with Monsanto;  this drug
has  higher  efficacy  and lower  side  effects  than  other  current  arthritis
treatments.  We have maintained our position in Warner-Lambert,  another stellar
performer, and have built new positions in Merck & Co. and Pharmacia & Upjohn.

Technology  was another  sector that  performed  well for us this past year.  In
fast-moving  sectors  like  technology,  I focus  on  excellent  management  and
competitive  position.  Industry  leaders  Dell  Computer,  Microsoft  and Cisco
Systems continued to out-execute competitors and generate substantial wealth for
shareholders.  I also added a sizable investment in America Online, an extremely
attractive franchise with a huge subscriber base and attractive business model.

We did have some  disappointments  toward the end of the year. Monsanto declined
in value after calling off its merger with American  Home  Products.  Management
also failed to meet earnings  targets.  I look for long-term value, but also for
companies  to  deliver  decent  results  in the near  term.  Even  Alice,  after
listening to the Queen lecture her about "jam

(1)  Both returns include reinvested dividends.

(2)  Lipper  Analytical  Services,  Inc. defines a growth and income fund as one
     that "combines a growth of earnings  orientation and an income  requirement
     for level and/or rising  dividends."  As of October 31, 1998,  Janus Growth
     and Income Fund ranked 23/296 for the 5-year  period.  The ranking is based
     on total return,  including reinvestment of dividends and capital gains for
     the stated period.

Past performance does not guarantee future results.

tomorrow," finally retorted "It must come sometimes to jam today."  Accordingly,
I substantially reduced our holding.

Some of our  financial  services  picks  declined in sympathy with global market
weakness.  I trimmed  positions,  but  believe  these  stocks can  recover  with
increased  earnings and capital  management next year. Fears of a recession also
caused  Porsche's  stock  to drop  substantially,  although  its  earnings  beat
expectations. Porsche continues to improve its manufacturing processes, enjoying
huge demand and a brand-name franchise.

The performances of our cable,  pharmaceutical and technology stocks demonstrate
that  Mae  West was  right  when she  said,  "Too  much of a good  thing  can be
wonderful."  While  these  dynamic  industries  make  up a  large  part  of  the
portfolio,  we're still  committed  to  mitigating  volalility.  Accordingly,  I
flattened  the position  sizes of many  holdings and  increased the weighting of
convertible preferred stocks that offer higher yields and downside protection.

Global  political  and  economic  turmoil  has  created  uncertainty,  but  also
opportunity.  Our  goals  going  forward  remain  top-quartile  performance  and
Index-beating  returns  with  lower  volatility.  Even so, I take no  solace  in
meeting only half of these goals this past year. However, I remain excited about
many of the great  companies  we've  uncovered.  The  research  team at Janus is
energized to continue to do what we do best:  intensive  fundamental research to
find great growth investments.

Thank you for your continued investment in Janus Growth and Income 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.

Janus | Mercury Fund

[PHOTO]
Warren B. Lammert
portfolio manager

I'm pleased to report that Janus  Mercury Fund gained  24.75%  during the fiscal
year ended October 31, 1998,  outpacing its benchmark,  the S&P 500 Index, which
appreciated  22.01%.(1) As a result of these  impressive  gains, the Fund ranked
8th out of 240 capital appreciation funds tracked by Lipper Analytical Services,
Inc., a leading mutual fund rating company.(2) This ranking placed Janus Mercury
Fund among  Lipper's  top-quartile  performers  for the  12-month  period  ended
October 31, 1998.

For most of the year, a  low-interest-rate,  inflation-free  backdrop  bolstered
both the U.S.  economy and the stock market.  However,  many stocks  experienced
sharp  setbacks  late in the period,  as fallout from the Asian  crisis  created
difficult  global economic head winds.  Most notably,  this fallout included the
Russian credit collapse and potential currency devaluations in Latin America.

Although fears relating to the  deterioration of emerging  economies  produced a
lot  of  noise  in  domestic  and  international  markets,  Janus  Mercury  Fund
prevailed.  Its  performance  was aided by strategic  adjustments  geared toward
portfolio consolidation. We reduced the number of positions in the Fund from 100
as of October 31, 1997,  to 57 as of October 31, 1998. We also  intensified  our
focus on businesses  we view as being less  sensitive to economic  weakness.  In
response to disappointing fundamental developments,  we sold several significant
European  holdings,  including Philips  Electronics,  Volkswagen and Electrolux.
Accordingly,  our European  weighting has declined to 6.4% from its previous 23%
on October 31, 1997.  Among the areas that  contributed  most to our performance
were cable, pharmaceuticals and selected technology stocks.

Our strongest cable stocks included MediaOne Group, Time Warner, Comcast and Cox
Communications  - all of which continue to drive the evolution of this industry.
In the very early stages of this evolution, we began a rigorous analysis of each
company,  visiting with their  managements,  scrutinizing  the  financials,  and
evaluating new value-added  services  currently  being  introduced to customers,
such as telephony  and data  services.  In doing so, we came to  understand  the
revenue  potential  of these new  services  much sooner than Wall Street did. We
continue  to  closely   monitor   progress  at  these  companies  and  expect  a
simultaneous decrease in capital spending and increase in free cash flow as they
near network upgrade completions.

Our life sciences positions also gained steadily as investors continued to favor
these stocks for their perceived  economic immunity and visible earnings growth.
Pfizer,  Warner-Lambert  and Pharmacia & Upjohn's stocks were all invigorated by
successful  product  launches.  We also added a new  position in IMS  Health,  a
company that compiles and sells  prescription  drug-use  data to  pharmaceutical
companies  to help them gain  insight  into  competitive  industry  trends.  The
increasing flow of successful new drug therapies emerging from the research labs
of the  pharmaceutical  industry has been  instrumental in boosting IMS Health's
revenue.

(1)  Both returns include reinvested dividends.

(2)  A capital  appreciation  fund is  defined  by  Lipper as one that  "aims at
     maximum capital appreciation, frequently by means of 100% or more portfolio
     turnover,  leveraging,   purchasing  unregistered  securities,   purchasing
     options,  etc. The fund may take large cash  positions."  As of October 31,
     1998, Janus Mercury Fund ranked 4/96 of capital  appreciation funds for the
     5-year  period.  Lipper's  ranking  is  based on  total  return,  including
     reinvestment of dividends and capital gains for the stated period.

Past performance does not guarantee future results.

Our technology  weighting also performed  well, led by Dell Computer,  Microsoft
and Cisco Systems.  New product cycles at these  companies  should advance their
stocks even further;  however,  I'm  concerned  that the strong  secular  forces
currently bolstering these companies' prospects may be threatened by the growing
possibility of an economic slowdown. With that said, we continue to monitor this
situation closely.

Not all of our  ideas,  however,  contributed  to the Fund's  impressive  gains.
Several of our financial services companies dragged on the Fund's performance as
a result of either real or perceived  loan  exposure to emerging  economies.  We
have reduced the Fund's weighting in this industry. We were also disappointed in
Parametric Technology's performance.  The company suffered from a sharp slowdown
in the domestic sales of its computer-aided  engineering software.  Parametric's
problems included increased competition from lower-priced competitors and a loss
of focus by management. We subsequently sold this position at a loss.

Going forward,  although I believe market volatility will probably continue, I'm
convinced  much  of it has  already  been  factored  in to  stock  prices.  But,
attractive  prices should continue to present  themselves  (even for some of the
very strong franchises), and when they do, we'll take advantage of them.

In closing,  I'd like to thank you for your continued  confidence and investment
in Janus Mercury Fund.

Claire Young
portfolio manager

Janus  Olympus  Fund gained  23.10% for our fiscal year ended  October 31, 1998.
During  the same  period,  the S&P 500  Index  gained  22.01%.(1)  The Fund also
achieved  a  top-quartile  ranking  for the  period,  placing it 12th out of 240
capital appreciation funds tracked by Lipper Analytical Services, Inc., a mutual
fund rating company.(2)

During fiscal 1998, there were two distinct periods in the market.  In the first
half,  the market  shrugged off the Asian currency  turmoil and posted  steadily
improving  returns.  U.S.  companies with steady earnings streams benefited from
strong  investor  demand.  In the second half,  the market  initially  continued
upward,  but many valuation  measures were approaching  uncharted  levels.  When
Russia missed certain debt repayment schedules,  investors revisited their fears
of the far-reaching, long-lasting impact of the Asian crisis. They chose to move
their money from stocks into the safe,  liquid U.S. 30-year Treasury bond. After
two successive  rate cuts by the Fed, which  restored  investors'  confidence in
stocks, the market rebounded.

I am pleased with the Fund's performance,  especially during the volatile second
half.  I believe  our focus on  companies  in  dynamic  growth  industries  with
superior product offerings and shareholder-driven management teams was rewarded.
The   fundamentals  of  our  investments   shone  during  a  year  fraught  with
disappointing results from many companies.

The exploding  corporate and consumer  utilization of the Internet provided many
attractive  investment  opportunities  for us this past year.  On the  corporate
side,  many  companies are  deploying  intranets as  communication  tools and as
access-to-information  repositories for employees,  customers and suppliers.  By
embracing  this new  technology,  they are finding ways to cut  development  and
delivery times,  eliminate errors and  redundancies,  and share information more
easily.

Cisco Systems, the market leader in computer networking technology, provides the
"plumbing" for these intranets.  Cisco is also a leading  proponent of using the
Internet to run its own  business,  as it receives $20 million per day in orders
and provides much of its customer  service over the Internet.  Veritas  Software
creates end-to-end storage management  solutions to control the data that reside
on computer systems.  As more and more information is stored and accessed on the
Internet,  Veritas is one of the key  vendors  helping  corporations  manage the
growth and reliability of their network data.

On the consumer side, people are using the Internet as an entertainment  medium,
information  resource  and  communication  tool.  America  Online is the leading
Internet  and  online  service  provider,  with 13  million  subscribers.  It is
becoming a key  destination  for  content  and  services,  as well as  marketing
dollars from corporations interested in reaching consumers through the Internet.

After  years of  monopoly  status,  the  U.S.  and  European  telecommunications
industries  are  undergoing  structural  changes.  Technology  is  allowing  new
entrants to quickly enter markets with competitive pricing, and new applications
are driving traffic growth. Colt Telecom Group is an alternative local telephone
company operating in 11 European cities. By providing  superior quality and high
customer service at competitive  prices,  the company is winning large customers
away from incumbent operators. WorldCom, a leading provider of services

(1)  Both returns include reinvested dividends.

(2)  A capital  appreciation  fund is  defined  by  Lipper as one that  "aims at
     maximum capital appreciation, frequently by means of 100% or more portfolio
     turnover,  leveraging,   purchasing  unregistered  securities,   purchasing
     options,  etc. The fund may take large cash positions." Lipper's ranking is
     based on total  return,  including  reinvestment  of dividends  and capital
     gains for the stated period.

population  ages and managed care companies focus on  pharmaceutical  use rather
than alternative  procedures to treat disease. A number of leading  prescription
drugs  continued to demonstrate  strong sales growth.  Warner-Lambert's  Lipitor
gained market share in the  cholesterol-lowering  arena. Pfizer's Viagra was the
fastest  prescription  drug  launch  in  history.   Schering-Plough's   Claritin
continues to benefit from weak competition and increased consumer awareness from
a successful marketing campaign.

I sold our oil services  companies on fears of weak oil demand  because of lower
Asian  consumption.  I also  sold  BankAmerica  Corporation  as  banks  began to
quantify their exposure to emerging markets' debt losses.

Looking  ahead,  the Fed's  recent  moves  have  demonstrated  the  government's
commitment to supporting the U.S.  economy,  which should bolster  confidence of
consumers  and  businesses.  Many  companies  have analyzed the magnitude of the
slowdown in other  economies and are taking steps to minimize the impact.  While
we may still see some  volatility in the months ahead,  I believe the underlying
fundamentals for our holdings remain intact and will be rewarded over time.

Thank you for your continued investment in Janus Olympus 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.

Janus | Overseas Fund (closed to new investors)

Despite a strong performance for the first nine months of the fiscal year, Janus
Overseas  Fund turned in a  disappointing  performance  for the 12 months  ended
October 31, 1998. The Fund returned  3.55%,  versus the MSCI EAFE Index's return
of 9.65%.(1)

The year was  characterized  by generally  buoyant  equity markets for the first
nine months, fueled by lower interest rates and positive earnings reports coming
primarily out of the U.S. and Western  Europe.  The Japanese and Asian economies
and stock  markets  were soft,  as we had  expected.  However,  in July,  global
markets began to capsize,  precipitated by the Russian currency  devaluation and
subsequent  debt  crisis.   The  Russian   situation  had  unexpectedly   severe
repercussions on all financial markets,  exacerbated by the highly leveraged and
precarious  Russian  positions held by some hedge funds. Many hedge funds had to
liquidate large positions,  putting tremendous pressure on the dollar, corporate
bonds and equity markets in general.  Other emerging markets sold off in tandem.
These  events,  coupled  with  political  and economic  uncertainties  in Japan,
Germany and the U.S.,  led to almost  unprecedented  volatility in the financial
markets.

The sell-off in financial markets was felt most sharply in Europe, which had the
largest gains  year-to-date.  The German DAX Index  illustrates this point: from
July to October, the DAX dropped 38% and, despite a 30% rally off the bottom, is
still down 24% from its high. The volatility in Europe had a large impact on the
Fund,  which  has more  than  two-thirds  of its  holdings  in the  region.  Our
relatively low weighting in Japan also hurt the performance versus the MSCI EAFE
Index,  as the Japanese  market proved more  resilient  than  Europe's.  Despite
hitting a 12-year  low  during  the  fourth  quarter,  the  Nikkei  average  has
underperformed  dramatically  for years and simply  did not have large  gains to
give up.

Our two  biggest  disappointments  were our  positions  in UBS,  the large Swiss
banking and  financial  services  conglomerate,  and Alcatel,  a French  telecom
equipment  vendor.  UBS got hit by the Russian debt crisis and had to write down
not only its loans to Russia,  but also its  exposure to hedge funds and Russian
bonds.  The stock suffered  additionally  from the general sell-off that hit all
financial stocks.  Alcatel, on the other hand, reported very disappointing order
trends in its public telephone business.  Weaker global economic growth also put
pressure  on  its  revenue  and  profit  outlook.  As  a  result,  our  earnings
expectations for both UBS and Alcatel were cut dramatically, and we reduced both
positions at a loss.

Other European  financial  stocks held by the Fund,  such as Deutsche Bank, Bank
Austria  and the  Italian  banks,  were also hit  during the  financial  crisis.
Holdings in these  positions were either sold or reduced as the potential  risks
to earnings from Russia,  hedge funds and poor market conditions  outweighed the
potential upside.  However,  we opted to hold other European  financial services
stocks given their underlying fundamentals and inexpensive valuations.

Additional  stocks  that sold off during the fourth  quarter  were  either  very
rapidly growing companies, such as Colt Telecom Group in the UK, or economically

30  Janus Equity Funds / October 31, 1998
<PAGE>

stocks with strong earnings  potential but a small current earnings base. In the
case of cyclical or economically  sensitive  businesses,  investors have already
priced a global  recession into many of these stocks.  Both categories of stocks
have rebounded (with some back at all-time  highs),  but cyclicals  remain below
recent levels as well as historical valuation measures.

Despite the disappointments in the fourth quarter, the Fund had many outstanding
stocks during the year. Among these were:  Wolters Kluwer, a Dutch publisher and
long-time  holding in the Fund;  Nokia, the Finnish telecom  equipment  company;
Rentokil  Initial,  a UK  support  services  company;  Cap  Gemini,  the  French
information technology company; and Capita Group, a UK outsourcing company. Also
notable were  Securitas,  the Swedish  security  firm, and Assa Abloy, a Swedish
lock manufacturer,  both of which we have mentioned before.  Compass Group, a UK
catering company and a relatively new holding,  was another winner.  On average,
these stocks were up more than 50%, and several more than doubled.

Looking  ahead,  we believe the worst of the  volatility is behind us and remain
positive  on the  outlook  for global  interest  rates.  Despite an  anticipated
softening  in economic  growth  rates,  we still  expect  modest  growth for the
upcoming  year.  Stock price  valuations  in foreign  markets  have come down to
levels we haven't seen for quite a while. In addition,  positive  secular trends
in Europe (such as increased focus on profitability  and shareholder  value) are
continuing.  Given these factors, we are cautiously  optimistic about the equity
markets and look forward to  continuing  to find good  investment  opportunities
overseas. Thank you for your continued confidence.

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.

These last few months have seen tremendous  levels of volatility in the markets.
While I was not surprised to see a correction of many stock  valuations  that in
my mind were  overextended,  I was surprised by the magnitude of the  correction
and the indiscriminate nature of the selling that accompanied it. For the fiscal
year ended October 31, 1998,  the Fund returned  8.49%,  while the S&P 500 Index
returned 22.01%,  the NASDAQ  Composite Index returned  11.16%,  and the Russell
2000 Index  returned  (11.84%).(1)  I am certainly not pleased or satisfied with
our results, however, I am very confident in the outlook for the companies we've
selected.

In light of the  severity  of the  global  market  volatility,  I want to take a
moment to discuss my views on the  turmoil  and how it  affected  my  investment
decisions.  It is easy to forget that any market  requires buyers and sellers to
stay in  equilibrium.  An excess of one or the other  creates an  imbalance  and
causes prices to rise or fall, often dramatically. More importantly, price moves
don't  necessarily  have  to be  based  on  intrinsic  value,  but can be due to
perception and psychology.

The series of events that  culminated in the correction in September came like a
cry of "Fire!"  in a movie  theater.  The  ensuing  stampede  to the exit was as
irrational as I have seen.  High-quality  stocks were dropping with seemingly no
bottom  because there simply were no buyers.  Valuation  became  irrelevant  and
liquidity  became  paramount.  In other words,  the most important  question for
buyers and sellers  wasn't "What is this stock worth?";  instead,  it was "Can I
sell this stock if I need to?" Cytec  Industries,  one of my favorite  specialty
chemical  companies,  declined from $54 to $15 in a period of four weeks. At its
bottom,  it was selling for six and  one-half  times free cash flow,  in my mind
equivalent  to a new  Porsche  selling for  $5,000.  Federal-Mogul,  the largest
position in the Fund,  declined from $72 to $33 at its lowest point.  This stock
also sold for about six and one-half times free cash flow.

While it was certainly frustrating to watch what the correction was doing to the
wealth of my shareholders,  from a different  perspective,  it was a very unique
opportunity  to reload the Fund with great  companies at  reasonable  prices.  I
doubled my position in Cytec at an average  cost of roughly  $18. It is now $24,
and I expect  this stock to  continue  to perform  well.  I was able to buy more
Federal-Mogul at $33, a price not seen since early 1997. The stock is now $54. I
also purchased a substantial amount of Bally Total Fitness and Chancellor Media.
Bally,  which I purchased in the low teens after the stock fell from $37, is now
$19, and Chancellor, which I purchased in the low $20s, is now $38.

Cable  companies,  a  significant  weighting  in the  Fund,  are  also  among my
favorites.  The stocks have been excellent  performers over the past year, and I
believe this will continue to be the case in the future.  My original  thesis on
these companies was that, as current capital  spending  budgets decline over the
next couple of years, a substantial amount of free cash flow

will be generated.  This is still the case.  Now,  however,  it is also becoming
clear  that even more cash flow  will be  generated  from new  services  such as
voice,  data and digital cable. As investors come to better  understand  this, I
believe these stocks will continue to outperform.

One  can  look  at a  correction  in  different  ways.  It can be  viewed  as an
opportunity  to sell, or it can be viewed as an  opportunity  to buy.  Those who
viewed it as an  opportunity  to sell were doing so without  regard to valuation
and often sold their stocks at substantial  discounts to their true worth. Those
who viewed it as an opportunity to buy were simply taking advantage of the state
of panic that had caused many to make irrational  decisions.  We viewed it as an
opportunity to buy.

I want to thank you for sticking with the Fund, even when things looked bleak. I
also want you to know that I have never  sold a share of the Fund and,  in fact,
took the recent  opportunity to add to my personal  holdings in the Fund.  There
will again be  occasions  when things  look bleak,  and the easy move will be to
sell.  I urge  to you not to take  the  easy  way  out.  If you are a  long-term
investor, the best time to invest is often when the consensus view would suggest
otherwise.  This  contradiction is precisely what creates the special situations
in which this fund invests. Thank you again for your support.

Scott W. Schoelzel
portfolio manager

It's truly been an extraordinary  year in many ways and I'd like to thank all of
you for your continued commitment and confidence.  For the 12-month period ended
October 31, 1998, Janus Twenty Fund  outperformed  the S&P 500 Index,  posting a
gain of 40.58%  compared to 22.01% for the Index.(1)  These  results  earned the
Fund a first-quartile  ranking,  placing it 2nd out of 240 capital  appreciation
funds  tracked  by  Lipper  Analytical  Services,  Inc.,  a mutual  fund  rating
company.(2)

One principle of the Fund is to invest in companies that simply provide more and
more of the goods and services you and I use in our everyday lives.  The pace of
innovation  of  products  and  services in the  telecommunications,  technology,
pharmaceuticals, financial services, retailing and media arenas has been nothing
short of phenomenal,  and at times it's difficult just to keep up. Nevertheless,
our research  analysts have done an extraordinary  job identifying and analyzing
the  opportunities  which  have  presented  themselves,  and no letter  would be
complete without acknowledging their outstanding work.

I genuinely believe the Internet will be the single most influential  phenomenon
affecting our lives over the next 10 years.  As Internet use infiltrates the way
we work,  learn,  and entertain  ourselves,  there should be an explosion of new
investment  opportunities.  We've chosen to invest in many  companies we believe
will  play a key  role in this  evolution.  That  said,  our  positions  in Dell
Computer,   Microsoft  and  America  Online  (AOL)  in  particular   have  added
significantly  to the performance of the Fund. For the year,  Microsoft's  stock
price advanced more than 60%, while Dell and AOL gained more than 220%.

Life sciences, and more particularly  pharmaceuticals,  is another area where we
continue to see a  proliferation  of  opportunities.  Our  positions  in Pfizer,
Warner-Lambert  and Eli Lilly all benefited  from the increased  acceptance of a
number of recently  launched drugs,  all which have proven to be very successful
in treating  everything  from elevated  cholesterol  levels to  osteoporosis  to
reducing the incidence of breast cancer.  Going forward,  we expect the pipeline
of  "blockbuster"  drugs to  accelerate  throughout  the  entire  life  sciences
industry.

Telecommunications  continues to offer great  potential as well.  Gains from our
relatively  new  position in Nokia,  a leader in the  cellular  phone  equipment
industry,  were driven by the increasing use of cellular phones both in the U.S.
and  around  the  world.  There  are  currently  about 250  million  subscribers
worldwide, and we expect an increase to more than 600 million in the next couple
of years.  We believe  Nokia is  well-positioned  to continue  to  maintain  its
leadership.

Despite the Fund's noteworthy returns,  there were stocks that fell short of our
expectations.  Our financial services positions,  once thought to be some of the
more  stable and  predictable  in the  portfolio,  proved to be some of the most
volatile.  The Asian economic crisis, Russian debt fiasco, hedge fund meltdowns,
and assimilation  difficulties with some of the  higher-profile  banking mergers
all  contributed to our loss of confidence.  We chose to liquidate our positions
in  both  Citigroup  and  BankAmerica,  but  will  continue  to  monitor  future
developments at

(1)  Both returns include reinvested dividends.

(2)  A capital  appreciation  fund is  defined  by  Lipper as one that  "aims at
     maximum capital appreciation, frequently by means of 100% or more portfolio
     turnover,  leveraging,   purchasing  unregistered  securities,   purchasing
     options,  etc. The fund may take large cash  positions."  As of October 31,
     1998,  Janus Twenty Fund ranked 2/96 for the 5-year period,  and 1/55 funds
     for the 10-year  period.  This ranking is based on total return,  including
     reinvestment of dividends and capital gains for the stated period.

Past performance does not guarantee future results.

both  of  these  firms  as  well  as  the  entire  financial   services  sector.
Fortunately,  the disappointing returns posted by these stocks weren't enough to
meaningfully impact the Fund's overall performance.

Looking ahead,  I believe market  volatility is here to stay. The speed at which
information  is now being  disseminated,  combined with its sheer volume and the
impact it has on the world's financial  systems,  will almost guarantee that the
volatility  we have seen is only a precursor to future market  actions.  Despite
this increase in volatility,  I remain very bullish on the longer-term prospects
for financial assets,  particularly growth stocks. I would, however, urge you to
maintain realistic expectations going forward. The average return on stocks over
the past 30 years is around 11%, not 40%,  and some years even  produce  losses.
(Yes, it can actually happen!)

Finally,  managing  Janus  Twenty Fund is so much more than just a job to me. As
many of you know, 100% of my personal portfolio is invested in the Fund, side by
side with each of you. So next time the market  swoons,  rest  assured that your
portfolio manager knows firsthand what you are going through and is working hard
to navigate the  uncertainties  of the  marketplace  with your best interests in
mind.

Thank you for your continued investment in Janus Twenty 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.

While the small- and mid-cap  sectors of the market  continued to lag large caps
through  most of the fiscal year,  Janus  Venture  Fund  returned  1.07% for the
12-month period ended October 31, 1998, outperforming its benchmark, the Russell
2000 Index, which returned (11.84%) for the same period.(1)

Additionally,  the Fund's performance  exceeded that of many of its peers during
the period.  It ranked 21st out of 588  small-company  growth  funds  tracked by
Lipper Analytical Services, Inc., a mutual fund rating company, which placed the
Fund in the top quartile for the year.(2)

In our letter to you at midyear,  we mentioned our plans to restructure the Fund
by  reducing  the  number of  positions  and  adding  to those  where we saw the
strongest potential for growth. In effect, the Fund became more focused,  though
no less diverse, as the number of names dropped from 197 at the beginning of the
year to 94 at fiscal year-end.

These changes enabled us to get back to our stock-picking roots, so to speak, by
providing  even more time for on-site  visits  with  company  managements.  In a
market  intolerant  of  earnings   shortfalls   (particularly   among  small-cap
companies), this continues to be critical to our ongoing research.

Unfortunately,  despite  strong  earnings for many of our  companies,  liquidity
concerns  drove  small-cap  prices down a number of times  throughout  the year.
Nonetheless,  we  continued  to treat  these  pricing  inefficiencies  as buying
opportunities, selectively adding to our favorite positions.

Among those we increased during the year were Veritas Software Corporation,  TCA
Cable TV, Inc. and MedImmune,  Inc. Veritas,  a developer of data management and
storage  software,  will likely benefit from a data  explosion  created by rapid
Internet growth.  We expect TCA to increase its cash flow by offering  customers
new, value-added services,  including telephony,  data and video-on-demand.  And
our  optimism  for  MedImmune  is  based  on  continued  strong  sales  from its
respiratory infection treatments, as well as a full product pipeline.

Despite a difficult  environment for small  technology  stocks,  our holdings in
this  area  continued  to do  well.  Significant  gains  posted  by  Engineering
Animation (one of our largest positions) helped buoy the Fund's performance. The
company's  stock  appreciated  as a  result  of the  growing  popularity  of its
three-dimensional engineering software, particularly among car manufacturers who
benefit from reduced development time.

Another large technology  holding that posted impressive  returns was Wind River
Systems, Inc. Although the stock was flat throughout much of the year, it gained
late in the period  following news of an agreement  with Intel.  The deal grants
royalties  to Wind River for each  computer  chip Intel  sells  containing  Wind
River's embedded software system.

(1)  Both returns include reinvested dividends.

(2)  A  small-cap  fund is  defined by Lipper as "a fund that by  prospectus  or
     portfolio   practice   invests   primarily   in   companies   with   market
     capitalizations  less  than $1  billion  at the  time of  purchase."  As of
     October 31, 1998,  Janus  Venture Fund ranked  93/190 for the 5-year period
     and 21/65 for the 10-year  period.  The  ranking is based on total  return,
     including  reinvestment  of  dividends  and  capital  gains for the  stated
     period.

Past performance does not guarantee future results.

We were also pleased with  MiniMed,  Inc., a stock that gained from the movement
toward more intensive medical  management of diabetes.  The company has captured
nearly 90% of U.S. market share for insulin pumps and is currently  awaiting FDA
approval for its new glucose sensor.

Two stocks that fell short of our expectations  were Concentra  Managed Care and
Computer  Learning  Centers.  Although  Concentra's  financial  profile appeared
solid, we trimmed our position when lackluster  earnings growth caused the stock
to falter.  We also  liquidated our position in Computer  Learning  Centers at a
loss  following  the  stock's  decline  on news that an  inspection  by the U.S.
Department of Education faulted the company for inaccurate record keeping.

The recent  underperformance  of the small-cap sector,  coupled with the extreme
volatility  of the overall  market,  has  created  tremendous  opportunities  in
small-company   stocks.   We  are  working   hard  to  take   advantage  of  the
inefficiencies  we see and are hopeful for solid  returns over the course of the
year.

In closing,  we'd like to thank you for your continued support and investment in
Janus Venture Fund.

For the 12-month period ended October 31, 1998, Janus Worldwide Fund appreciated
11.40%  compared to the MSCI World  Index,  which  returned  15.26%.(1)  Despite
lagging its index, the Fund achieved a top-quartile ranking, placing 47th out of
211 global  funds  tracked by Lipper  Analytical  Services,  Inc., a mutual fund
rating company.(2)

The fiscal year was the most  volatile  12-month  period in recent  memory.  The
first three  quarters  reflected  generally  buoyant equity  markets,  fueled by
continued modest growth and low interest rates primarily in the U.S. and Europe.
Asian markets and  economies  were  relatively  weak in  comparison,  but helped
contribute to the general optimism  regarding  sustainable global growth and low
interest rates. While the unresolved banking crisis in Japan was troublesome, it
was viewed more as a regional problem.  However, the global equity markets began
to  stumble  in  July  when  Russia  devalued  its  currency  and   subsequently
restructured its debt  obligations.  This sent widespread  shocks throughout the
global financial  markets,  primarily  because of the highly  leveraged  Russian
positions held by hedge funds.  Forced liquidations of hedge funds pressured the
dollar, corporate bonds and the broad equity markets, while fears of losses were
particularly  pronounced  among  financial  stocks.  As a result,  global growth
forecasts were slashed.  Political concerns in Japan,  Germany and the U.S. also
contributed to the sell-off.  Hardest hit were the European  bourses,  which had
the largest gains to date.

In September and October,  the Federal Reserve intervened with two interest rate
cuts,  helping global markets rally.  Although the U.S.  market regained much of
its losses near the end of the period,  the international  markets remained well
below their summer highs.  Intraday  volatility  returned to more normal levels,
and market participants focused once again on fundamentals.

The Fund had a number of winners  and a few losers.  Two of our U.S.  technology
stocks,  Microsoft and Cisco Systems,  contributed  solid gains, and we added to
these positions on market declines.  Other strong U.S.  performers  included our
cable positions in Time Warner, Comcast and  Tele-Communications,  Inc., as well
as pharmaceutical  powerhouses like  Warner-Lambert  and  Bristol-Myers  Squibb.
European  information  technology  companies  were also  winners,  including Cap
Gemini,  Getronics and Atos.  Business  support  services in Europe  contributed
strongly to results,  with  Rentokil  Initial,  Securitas,  Hays PLC and Compass
Group all posting large gains.  Telecommunications  equipment maker Nokia turned
in an outstanding  performance,  benefiting from huge global demand for cellular
telephony.  Telecom service providers  MCI-WorldCom and Swisscom (a new holding)
were strong performers as well.

However,  European  financial  stocks,  which we had held  because of  declining
interest  rates and industry  consolidation,  were broadly hit by the  financial
crisis  mentioned  earlier.  Our  biggest  loser was UBS in  Switzerland,  which
suffered  from  exposure to both Russia and hedge  funds.  Despite the  positive
benefits from  cost-cutting  and an attractive  private  banking  business,  the
earnings potential of UBS was impaired by write-downs and market volatility.  We
significantly  reduced this position at a loss. Some smaller financial  holdings
were also hurt,  such as Deutsche Bank and Bank Austria,  and we liquidated  and
cut these positions, respectively. However, we

(1)  Both returns include reinvested dividends. Net dividends reinvested are the
     dividends that remain to be reinvested  after foreign tax obligations  have
     been met. Such obligations vary from country to country.

(2)  A global fund is defined by Lipper as one that "invests at least 25% of its
     portfolio in securities  traded  outside the United States and may own U.S.
     securities  as well." As of October  31,  1998,  Janus  Worldwide  Fund was
     ranked 3/66 for the 5-year  period.  This ranking is based on total return,
     including reinvested dividends and capital gains for the stated period.

maintained  our  holdings  in other  European  financials  based  upon  positive
fundamentals and low valuations, and added select names to the portfolio.

Stocks with economic  sensitivity  were hit during the sell-off by growing fears
of a global recession. Even companies that exceeded earnings expectations,  like
Renault, Porsche and Electrolux,  declined. Two of our holdings,  French telecom
equipment  manufacturer  Alcatel and Dutch consumer  electronics company Philips
Electronics,   experienced  earnings  shortfalls  because  of  weakening  global
economies. We cut these positions based upon our reduced earnings estimates.

Looking ahead, we foresee slower global  economic growth and favorable  interest
rates.  Japan's  economy is still  decelerating,  while its government  stumbles
toward a solution for the banking crisis and economic malaise.  Nonetheless,  we
are finding select  opportunities  here.  Asian economies have  stabilized,  but
equity valuations are expensive relative to earnings potential.

In Latin America, which is experiencing slower economic growth, we are currently
focusing on the telecom  sector.  While in the U.S.  and Europe,  we continue to
expect  modest  growth  coupled  with  measures  to  improve  profitability  and
shareholder value. The bulk of our holdings is concentrated here.

Recent market  volatility,  while  frustrating,  has created many new investment
opportunities.  By seeking out  companies  globally with strong  franchises  and
improving  fundamentals,  we hope to find good investment  returns over the long
term regardless of short-term market movements.

Thank you for your continued investment in Janus Worldwide Fund.

ECU - European Currency Unit

*Non-income-producing security

** A portion of this  security  has been  segregated  by the  custodian to cover
   segregation requirements on forward currency contracts.

+ Securities  are registered  pursuant  to Rule  144A  and may be  deemed  to be
  restricted for resale.

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.  Twelve  series of shares  ("Equity  Funds" or  "Funds")
   included in this report invest primarily in equity  securities.  Each Fund is
   diversified  as  defined  in the  1940  Act,  with  the  exception  of  Janus
   Enterprise,  Janus Olympus,  Janus Special Situations and Janus Twenty Funds,
   which are  nondiversified.  

   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 obtained from one or
   more  dealers  making a market for such  securities  or by a pricing  service
   approved by the Funds'  Trustees.  Short-term  securities  maturing within 60
   days 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 their 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 CURRENCY TRANSACTIONS AND FUTURES CONTRACTS
   The Funds 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  exchange  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 from 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 Funds'  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 resultant  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 (i.e., treated as realized and subject
   to distribution) 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 Funds may enter into "futures  contracts"  and  "options" on  securities,
   financial indexes and foreign currencies, forward contracts and interest rate
   swaps and  swap-related  products.  The 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.

Notes to | Financial Statements (continued)

   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.

   DIVIDEND DISTRIBUTIONS AND EXPENSES
   Dividends for Janus Balanced, Janus Equity Income and Janus Growth and Income
   Funds are declared and distributed quarterly,  and capital gains (if any) are
   distributed  annually.  The remaining nine Equity Funds generally declare and
   distribute  dividends  and capital gains (if any)  annually.  Each 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.

   For the fiscal year ended  October 31, 1998,  the  following  percentages  of
   fiscal year distributions were considered  long-term gains; Janus Fund - 73%,
   Janus Twenty Fund - 66%, Janus Venture Fund - 98%, and Janus  Enterprise Fund
   - 100%.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

   The advisory agreement with the Funds spells out the fees that the Funds must
   pay for the period ended  October 31, 1998.  Each of the Funds was subject to
   the following schedule:

                     Average Daily Net                Annual Rate  
   Fee Schedule      Assets of Fund                  Percentage (%)

   Equity Funds      First $300 Million                  .75
                     Next $200 Million                   .70
                     Over $500 Million                   .65
   ----------------------------------------------------------------

   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  (excluding Janus and Janus Venture
   Funds)  for  transfer   agent   services   plus   reimbursement   of  certain
   out-of-pocket expenses (primarily postage and telephone charges).

   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.  DST  Securities,  Inc., a wholly owned  subsidiary  of DST, is
   designated  as an  introductory  broker on  certain  portfolio  transactions.
   Brokerage  commissions paid to DST Securities,  Inc. serve to reduce transfer
   agent fees and expenses. Brokerage commissions paid, fees reduced and the net
   fees paid to DST for the year or period  ended  October 31,  1998,  are noted
   below.

3. FEDERAL INCOME TAX

   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, 1998,  have been
   reclassified among the components of net assets as follows:

   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, 1998 are available
   to off set future  realized  capital gains and thereby reduce further taxable
   gains distributions.  These carryovers expire October 31, 2006. The aggregate
   cost of  investments  and the  composition  of  unrealized  appreciation  and
   depreciation  of investment  securities for federal income tax purposes as of

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, 1998.

   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.

   Funds that invest in foreign securities also provide a summary of investments
   by country.  This summary reports the Fund's exposure to different  countries
   by providing the percentage of securities invested in each country.

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.

<PAGE>

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.

   Expense   ratios  prior  to  any  expense   offset  are  part  of  disclosure
   requirements  imposed  in  1996.  Years  prior  to 1995 do not  reflect  this
   information.

   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.

                                             Report of | Independent Accountants

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 Fund, Janus Balanced Fund,
Janus  Enterprise  Fund, Janus Equity Income Fund, Janus Growth and Income Fund,
Janus Mercury  Fund,  Janus Olympus Fund,  Janus  Overseas  Fund,  Janus Special
Situations Fund, Janus Twenty Fund, Janus Venture Fund, and Janus Worldwide Fund
(twelve of the portfolios  constituting  the Janus  Investment  Fund,  hereafter
referred to as the  "Funds") at October 31,  1998,  the results of each of their
operations for the year then ended,  the changes in each of their net assets 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,  1998 by
correspondence  with the custodian and brokers,  provide a reasonable  basis for
the opinion expressed above.

                                        Euro-Conversion | Discussion (unaudited)

On January 1, 1999, eleven European countries will convert to a common currency:
Austria,   Belgium,   Finland,  France,  Germany,  Ireland,  Italy,  Luxembourg,
Netherlands,  Portugal,  and Spain.  Investments  traded in the markets of these
countries will be  denominated  in the new currency,  referred to as the "Euro."
Conversion  to the Euro may present  certain risks to  investments  of the Funds
held in one of the currencies  that is being replaced.  Janus Capital,  however,
does not believe that the conversion  will have a material  impact on the Funds'
investments.

                                              Year 2000 | Discussion (unaudited)

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.
