DEAR SHAREHOLDER:
 
This report relates to the operations of the JNL Series Trust for the year ended
December 31, 1998. The following Money Manager  commentaries,  graphs and tables
provide you with  information  regarding  each  Series'  performance  during the
period.
 
                                  JNL AGGRESSIVE GROWTH SERIES
                                  JANUS CAPITAL CORPORATION
          [JANUS LOGO]            WARREN B. LAMMERT
 
OBJECTIVE:
 
JNL Aggressive Growth Series seeks as its investment  objective long-term growth
of  capital  by  investing  primarily  in common  stocks of issuers of any size,
including  larger,  well-established  companies  and  smaller,  emerging  growth
companies.
 
MONEY MANAGER COMMENTARY:
 
Despite dramatic volatility in 1998, global equity markets moved higher.  Stocks
began the year with a broad-based rally buoyed by strong corporate  earnings and
a resilient domestic economy.  In late spring,  the rally narrowed  dramatically
with small- and mid-sized  companies  falling behind their larger  counterparts.
Then, in mid-summer,  stocks began a precipitous  decline after Russia defaulted
on its debt. As liquidity dried up, the world's financial system teetered on the
edge of collapse as several  highly  leveraged  hedge funds sold  securities  to
cover their losses.  In response,  the Federal  Reserve  lowered  interest rates
three times in the fall. This Fed action sufficiently restored investor appetite
for  risk  and  stocks  rallied  for  the  remainder  of the  year in  spite  of
substantial political turmoil in the United States.
 
Turning to the Series, we outperformed our benchmark,  the S&P 500 Index, due to
our  focus  on  growth  stocks  in the  technology,  pharmaceutical,  and  cable
industries,  as well as individual names with compelling growth stories.  In the
technology  sector, we benefited from substantial gains in our  Internet-related
companies.  Pioneering online retailer  Amazon.com  enjoyed a tremendous run-up,
reflecting the rapid expansion of its franchise to cover an increasingly diverse
product line.  Another winner was Cisco Systems,  the leading network  equipment
supplier,  and a  prime  beneficiary  of  the  growth  of the  Internet.  On the
downside,  our position in Parametric  Technology  was  disappointing  after its
earnings fell short of our expectations. We sold the position at a loss.
 
Looking  forward,  despite low interest rates and an absence of inflation,  more
companies are expected to see their earnings come under pressure.  Additionally,
economic  uncertainty  abroad and political  instability at home are expected to
contribute to market volatility. However, this potential uncertainty could cater
to our  strength  as  stockpickers  as we  will  continue  to seek  out  growing
businesses in dynamic industries.

                                  JANUS CAPITAL CORPORATION
          [JANUS LOGO]            JAMES P. GOFF
 
OBJECTIVE:
 
JNL  Capital  Growth  Series  is a  non-diversified  Series  that  seeks  as its
investment  objective long-term growth of capital by emphasizing  investments in
common  stocks  of  medium-sized  companies.  Although  the  Series  expects  to
emphasize such securities, it may also invest in smaller or larger companies.
 
MONEY MANAGER COMMENTARY:
 
In a year marked by heightened  volatility,  equity markets posted mixed results
in 1998.  During  the  first  four  months,  equities  advanced,  driven by mild
inflation and strong corporate profits. Then, in the late summer and early fall,
stocks endured a precipitous  sell-off after concern  mounted over the viability
of  selected  emerging  market  economies.  With  the  world  on the  verge of a
financial  meltdown,  the Federal  Reserve  intervened  by  lowering  short-term
interest rates three times.  This increased  liquidity spurred stocks higher for
the remainder of the year in spite of severe political turmoil.
 
Turning to the Series,  we are pleased to report that we outpaced our benchmark,
the S&P MidCap 400 Index, reflecting strong gains by our technology,  media, and
pharmaceutical positions.  Among our technology holdings,  Vitesse Semiconductor
soared on robust  demand in the  voice and data  communications  market  for its
high-speed,  high-frequency chips. In the media arena, billboard company Outdoor
Systems shook off recession fears to rebound solidly. Consolidation continued to
drive revenue  growth in the radio and outdoor media  sectors,  making  earnings
less vulnerable to advertising budgets and the economy.
 
In the  pharmaceutical  industry,  our position in Sepracor was a standout.  The
company reformulates and patents  single-isomer  versions of existing drugs in a
procedure  that  eliminates  many of the drugs'  negative side  effects.  On the
downside,  we were  disappointed  with the  performance  of  Paychex,  a payroll
processing  company,  which  declined on concerns  over a potential  slowdown in
employment growth.
 
Looking ahead, we believe that this market is playing  directly to our strengths
of strong research and the ability to identify all-weather growth companies.  As
many large capitalization companies see their profit margins erode, the key will
be to own those  companies that can meet or exceed Wall Street's  estimates.  In
this  environment,  we believe  small and  midcap  companies  continue  to offer
significant opportunities.

          [JANUS LOGO]            HELEN YOUNG HAYES
 
OBJECTIVE:
 
JNL Global Equities Series seeks as its investment objective long-term growth of
capital by investing  primarily in common stocks of foreign and domestic issuers
of any  size.  This  Series  normally  invests  in  issuers  from at least  five
different countries including the United States.
 
MONEY MANAGER COMMENTARY:
 
Extreme   volatility  gripped  the  global  equity  markets  in  1998.  After  a
substantial  run-up during the first six months of the year,  stocks took a turn
for the worse following Russia's announcement that it could not service its debt
and that it would be forced to devalue its currency.  In response to the Russian
meltdown,  investors  indiscriminately  sold securities with any degree of risk.
The selling was  compounded  by several  hedge funds,  which were forced to sell
securities when several arbitrage techniques that they had employed backfired on
them. With liquidity nearly absent,  central banks from around the world lowered
interest rates through year-end. With liquidity restored,  investors returned to
riskier securities,  including stocks.  Consequently,  equities moved higher for
the  remainder of the year,  with  selected U.S.  technology  stocks  exhibiting
particular strength.
 
The Series  outperformed  its  benchmark,  the MSCI World  Index,  due to strong
performance from a number of telecommunications  and technology  companies.  For
instance,  our position in Nokia, the Finnish cellular phone company,  enjoyed a
wonderful  year as it  continued  to take  market  share  in a  growing  market.
Mannesmann,  the  German  conglomerate,  also had a strong  year as the  company
continued to transform itself into a telecommunications  company.  Additionally,
the company is finding the European  competitive  landscape,  which has recently
been deregulated,  to be very receptive to its strategies.  On the downside, our
European  financial  holdings,  such as UBS, were sold-off  dramatically  in the
summer after  investors  speculated  about the  magnitude  of their  proprietary
losses in Russia.
 
Looking ahead,  with worldwide  commodity prices currently at depressed  levels,
inflationary  pressures remain benign,  which is keeping a lid on interest rates
around the world.  This bodes well for equity  markets in the U.S.  and  Europe.
However,  the  uncertain  economic  outlook  for  Japan  has  led  us to  keep a
relatively  light weighting in Asian stocks.  We will continue to concentrate on
companies  that can grow  their  earnings  regardless  of the  broader  economic
environment.

                                  JAMES G. REILLY
  [ALLIANCE CAPITAL LOGO]         SYED HASNAIN
 
OBJECTIVE:
 
JNL/Alliance Growth Series seeks as its investment objective long-term growth of
capital by investing  primarily in common stocks or securities with common stock
characteristics which demonstrate the potential for appreciation.
 
MONEY MANAGER COMMENTARY:
 
We are pleased to report that over the period  February 28, 1998 to December 31,
1998,  the portfolio  returned  32.80%.  The S&P 500 rose 18.61% and the Russell
1000 rose 25.3% over the same  period.  The  Series'  outperformance  versus the
indices was driven by strong stock selection within our investment  process and,
especially  in the third  quarter,  our  decision to increase  holdings in a few
stocks that had been over-sold despite intact fundamentals.
 
Strong  performing  sectors for the year were technology and retailing where the
portfolio is  overweight  versus the S&P 500. Key  technology  holdings  include
Cisco Systems +152% for the year, Dell +255%,  Nokia +254%, and Microsoft +117%.
Discount  retailers produced excellent same store sales and therefore Home Depot
+109%,  Dayton Hudson +56%,  Kohl's +76% and Wal-Mart +108% all performed  well.
Pharmaceutical stocks were also exceptional  performers,  showing strong revenue
growth and promising new drug pipelines.  Significant positions included Bristol
Myers Squibb,  which was up 41% for the year, Pfizer +67%, Schering Plough +81%,
and Warner  Lambert  +77%.  The  overweight  position in  financial  stocks hurt
performance.  Several of these holdings have  outperformed  the market including
American  International  Group,  Federal Home Loan Mortgage Corporation and MBNA
Corporation and continue to be substantial  holdings in the portfolio.  However,
we have reduced  positions  in certain  money center banks and brokers as we are
less confident in their ability to generate consistent earnings growth.
 
Our  investment  approach is to hold fairly  concentrated  positions  in our top
twenty-five  holdings.  We research  these  companies  thoroughly and then trade
around  a  core  position  taking  advantage  of  market  and  individual  stock
volatility.  Stock  selection  accounts for  two-thirds  of the  outperformance,
intra-period  trading  around  core  positions  accounts  for  one-third  of the
outperformance.
 
The portfolio  remains  weighted toward industry  dominant  companies in rapidly
growing sectors of the economy.  The lack of pricing power for many corporations
forces a renewed focus on volume  growth and expense  control.  The  technology,
retailing,  and pharmaceutical  stocks within the portfolio have demonstrated an
ability  to grow  earnings  in excess of the market as a whole  despite  minimal
pricing  power.  The  financial  stocks  remaining  in the  portfolio  have also
demonstrated   consistent  earnings  power  and  will  likely  help  dampen  the
volatility of the portfolio.
 
We believe  that 1999 will be another  year of moderate  growth for the U.S. and
Europe  with  subdued  inflation.  Thus,  1999  may be  similar  to 1998 in many
respects.  Interest rates should remain low under a vigilant Federal Reserve and
European  Central Bank. The Southeast  Asian crisis appears to be bottoming with
painful  progress  in Korea and  Thailand.  China's  ability  to avoid  currency
devaluation  in 1998  is  evidence  of some  strength  in its  economy.  Japan's
restructuring of its banking system also appears to be moving forward.  Although
the potential for a mid-year correction in the stock market related to Year 2000
computer  problems is a  possibility,  we believe any  correction  will be short
lived.  We remain  concerned about Russian  instability  and Brazil's  financial
crisis but would expect the world community to provide sufficient  assistance to
avoid a dramatic  spillover impact elsewhere.  With low interest rates around 5%
as modest  competition  for capital and with the aging  populations in developed
nations increasing savings, U.S. equities should benefit from continued domestic
and  international  fund flows.  Under this  environment,  large company  growth
stocks should likely outperform again.

[FRED ALGER MANAGEMENT LOGO]      DAVID D. ALGER
 
OBJECTIVE:
 
JNL/Alger  Growth Series seeks as its  investment  objective  long-term  capital
appreciation by investing in a diversified, actively managed portfolio of equity
securities,  primarily  of  companies  with total  market  capitalization  of $1
billion or greater.
 
MONEY MANAGER COMMENTARY:
 
1998 proved a turbulent and  challenging  year for  investors in the U.S.  stock
market.  During the first half of the year,  stocks  that had been  undeservedly
oversold in the wake of the Asian crisis rebounded  nicely.  Inflation  remained
subdued and the Federal  Reserve left interest rates  unchanged.  The post-Asian
crisis earnings season came and went with some predictable casualties,  but most
companies  got through it unscathed.  Moreover,  after a year where value stocks
significantly  outperformed  growth  stocks,  investors  returned  to  the  more
aggressive  discipline.  By mid-July,  most major market indices were trading at
record levels.
 
Amid incidents of  international  economic  instability  and domestic  political
controversy,  the market  sold off  dramatically  in August.  Specifically,  the
Russian  economy  collapsed and the state of Japan's  banking  system  worsened.
Economic  activity was slowed by a credit crunch,  as spreads between  corporate
and treasury bonds widened.  As measured by the S&P 500 Index,  the historically
placid month of August proved to be the worst month since  October of 1987.  The
markets  recovered  during  September in anticipation of relief from the Federal
Reserve,  yet sold off sharply  toward the end of the month  following  what was
perceived to be a disappointing  reduction of the Federal Funds Rate by 25 basis
points.
 
As October  progressed,  stocks  gained a boost from a rare  intra-meeting  rate
reduction by the Fed. The technology sector  stabilized as Intel,  Microsoft and
Apple all reported better than expected quarterly earnings.  A rally prompted by
additional relief from the Fed in November  highlighted a strong fourth quarter,
which anchored another lucrative,  albeit  challenging,  year for the U.S. stock
market.
 
For the year ended  December  31, 1998,  the Series'  total return was 45.66% as
compared  to 28.58% for the S&P 500.  During  this  volatile  period,  investors
favored  larger,  more  predictable  stocks.  In  particular,  the Series' heavy
exposure to  healthcare,  retailing  and  technology  stocks  enabled it to post
strong returns.
 
In  conclusion,  1999 should be a wonderful  year for the  American  economy and
American  investors.  While we believe there are going to be problems around the
world,  overall we expect the stock market to continue to chug along.  Moreover,
while corporate profit growths should be subdued this year,  growth in America's
more  dynamic  sectors  should  once again be  spectacular,  and we expect  that
high-quality growth companies, which have the ability to generate high levels of
earnings, will once again be rewarded by investors.

                                  EAGLE ASSET MANAGEMENT, INC.
[EAGLE ASSET MANAGEMENT LOGO]     TEAM MANAGEMENT
 
OBJECTIVE:
 
JNL/Eagle Core Equity Series seeks as its investment objective long-term capital
appreciation  and,  secondarily,  current  income by  investing  primarily  in a
diversified  portfolio of common stocks which is believed to offer above-average
potential for long-term  growth.  To achieve this,  the  sub-adviser  uses three
different  investment   strategies  each  with  its  own  independently  managed
portfolio.   The  Series'  assets  are  allocated  40  percent  to  the  "Growth
Portfolio",  40 percent to the "Value  Portfolio"  and 20 percent to the "Income
Portfolio".  The Growth Portfolio  emphasizes  securities of blue chip companies
with growing earnings that are industry leaders and have market  capitalizations
in excess of $5 billion. The Value Portfolio emphasizes  securities of companies
with market  capitalizations  in excess of $1 billion  and that are  financially
sound but whose stock trades at a discount to its estimated intrinsic value. The
Income Portfolio emphasizes securities of companies with market  capitalizations
in excess of $1 billion that provide a stable or rising income stream.
 
MONEY MANAGER COMMENTARY:
 
During the global market  turmoil  stemming from Asia that prevailed for much of
1998,  U.S.  equity  markets  continued to be driven by investor  preference for
liquidity,  size, quality, and earnings growth at any price.  Consequently,  the
larger indices offer a misleading indication of overall market performance.  For
example,  though  the  S&P  500,  which  was  heavily  influenced  by  expensive
technology and drug issues,  was up 28.58% for the year, the median stock in the
index was up only 3.5%. The continued bull market in the second half of the year
was sparked in part by the Federal  Reserve's  three interest rate cuts totaling
0.75%.  The  additional  monetary  liquidity,  with the money supply  posting an
increase of 15.3%  year-over-year,  contributed to the continued market surge in
the face of sustained pressure on corporate earnings.
 
For 1998, the Series  increased 16.54% compared to a 28.58% increase for the S&P
500. On an individual  basis,  the Growth  Portfolio  gained  37.36%,  the Value
Portfolio  gained 1.25% and the Income  Portfolio  gained  8.78%.  The flight to
quality caused by the global  financial  market turmoil,  made it a particularly
difficult year for value and equity income investing, but the combination of the
three Portfolios  helped to moderate much of the market  volatility  experienced
throughout the year.
 
The Growth Portfolio was positively  impacted by  overweightings  in technology,
pharmaceuticals  and medical  devices and financial  services.  During 1998, the
technology  sector  benefited  from the ongoing  need for  domestic  and foreign
companies to invest in technology in order to remain  competitive  in the global
market  place.  Pharmaceutical  and  medical  device  companies  benefited  from
increasing  prescription  volumes,  new  products and aging  demographics.  U.S.
financial  institutions  benefited  from a  healthy  domestic  economy  and  are
beginning to capitalize on strategic investment  opportunities in other parts of
the world that have emerged as a result of the recent financial turmoil in those
regions.
 
The Value  Portfolio was cautiously  positioned for much of the year. The stocks
in  this  Portfolio  tended  to be  larger,  less  cyclical,  quality,  domestic
companies. The Portfolio's retail, telephone and financial service holdings were
generally  positive   performers,   whereas  the  energy  and  tobacco  holdings
negatively impacted performance.
 
The Income  Portfolio also tended to be  defensively  positioned for much of the
year.  Positive  contributions  in 1998  came  from  the  healthcare,  financial
services  and  pharmaceutical  sectors,  and,  as one  would  expect in a rising
market,  REITS and electric  utilities  tended to lag the overall market thereby
negatively impacting performance.
 
The U.S.  economy is doing  reasonably  well heading into 1999 although there is
evidence of a modest  slowdown as we cannot remain immune  forever to the global
economic  turmoil.  A  moderating  economy  and  benign  inflation   environment
typically  lead to declining  interest  rates.  We believe this  environment  is
likely to benefit all categories of U.S. equities.  There is, however, likely to
be significant  volatility  until  investors can better assess the impact of the
Asian and Latin American problems on U.S. corporate earnings.

OBJECTIVE:
 
JNL/Eagle  SmallCap  Equity  Series  seeks  long-term  capital  appreciation  by
investing primarily in equity securities of smaller companies which are believed
to offer potential for rapid growth.
 
MONEY MANAGER COMMENTARY:
 
Small cap stocks  started  1998  strong,  with the Russell  2000 posting a first
quarter  gain of 10.1%.  However,  fears  over  weakness  in the  Asian  economy
dominated  much of the  negative  sentiment  that  began to build in the  second
quarter when the Russell 2000 dropped 4.7%.
 
The  bottom  then  fell out of the small cap  market  in the  third  quarter  as
investor preference for highly liquid, large cap stocks caused a sharp reduction
in all  market  segments  other  than  large  cap U.S.  growth  stocks  and U.S.
Treasuries.  During the third  quarter  alone,  the Russell 2000 dropped  20.2%,
making it one of only three  quarters in the  preceding  two decades with a drop
exceeding 20%.
 
The downward trend that began in the second quarter and accelerated in the third
quarter  reached  bottom on October 8th when the Russell  2000 was off 36.9% for
the year. By the end of the year, however,  the Russell 2000 had rebounded 36.0%
from the trough, posting a positive 16.3% gain for the fourth quarter and ending
1998 down only 2.55%.
 
For 1998,  the Series was up 1.18%,  compared to a 2.55% decline for the Russell
2000. The Federal Reserve Board's  reductions in interest rates during the third
and fourth quarters  provided the Series with a catalyst to reinvigorate many of
its holdings that had been oversold during the summer and early fall. The Series
was up 22.67%  for the  fourth  quarter,  led  higher by the  sharp  rebound  in
technology and medical  device/pharmaceutical  companies.  In addition,  insider
buying and corporate share  repurchases by many small cap companies  helped fuel
the late recovery.
 
During the first half of the year, the retail sector continued to thrive. At the
same time,  we also began to reduce the Series  exposure to the energy sector as
we expected energy demand to decrease due to the global economic slowdown.
 
During the difficult summer months,  technology,  financial  services and energy
were the most negatively  impacted sectors.  As the Asian crisis  continued,  we
began to further reduce the Series exposure to certain cyclical  businesses with
significant  Asian  exposure.  During  this  volatile  period,  the  Series  was
positioned defensively,  with a focus on domestic companies with strong business
fundamentals  that we believed  would be able to  withstand  the extreme  market
fluctuations.
 
We also began to take advantage of the  opportunity to buy  fundamentally  solid
companies whose valuations we believed had reached irrationally low levels. As a
result,  several of the  purchases  made  during the second and third  quarters,
particularly in the technology and healthcare sectors,  performed extremely well
toward the latter half of the year. In addition, several long-term holdings also
started moving upwards as investors  began focusing on the earnings  strength of
their relative valuations.
 
Morgan  Stanley  Equity  Research  noted  that 1998 was the  worst  year for the
Russell 2000 Index in terms of relative performance since its inception 20 years
ago.  For the  year,  the  Russell  2000  trailed  the S&P 500 by more than 30%.
History  shows that periods of  substantial  outperformance  by small cap stocks
tend to follow periods of significant relative  underperformance.  If this trend
holds  true to form,  the small cap  market  may be about to enter a  protracted
period  when it will  outperform  the large cap market.  With  global  financial
concerns  abating,  investor  confidence  increasing  and  small  cap  stocks at
historically low valuations,  we believe that 1999 may be the year for small cap
stocks.

                                  MARKETS SERIES
                                  J.P. MORGAN INVESTMENT MANAGEMENT INC.
      [J.P. MORGAN LOGO]          TEAM MANAGEMENT
 
OBJECTIVE:
 
JNL/JPM  International  &  Emerging  Markets  Series  seeks  as  its  investment
objective  to provide  high total  return by  investing in a portfolio of equity
securities of foreign  companies in developed and, to lesser extent,  developing
markets.
 
MONEY MANAGER COMMENTARY:
 
Since the Series'  inception  date, the Series'  returned  -1.24%.  The MSCI All
Country World (ex U.S.) Index returned 2.11%.
 
The developed  international equity markets achieved a very credible return over
the course of 1998,  despite a very  difficult  period during the summer months.
European  equity markets,  in particular,  started the year in a strong fashion,
reflecting  the continued  optimism  over the  prospects for corporate  profits.
During the summer  months,  global market  turmoil spread from Asia to Russia to
Latin America,  calling into question the near-term earnings estimates in equity
markets,  both  developed and emerging  around the world.  Continental  European
markets  suffered much of the pain, as investor  sentiment waned.  However,  the
global market turmoil of the third quarter  turned to global market  euphoria in
the fourth quarter as markets everywhere rallied strongly. Stocks were helped by
moves to ease monetary  policy in the U.S. and Europe,  with the Federal Reserve
cutting the overnight rate twice during the quarter,  and towards year-end,  the
European Central Bank  orchestrating a coordinated rate cut. While many continue
to worry about a slowing global economy,  the quick responses from central banks
and the  overreaction  to  negative  news  during the summer  provided  room for
pleasing equity returns.
 
In contrast to Europe,  the  Japanese  market fell over the year,  although  the
strength of the Yen in the final quarter  resulted in a positive  return in U.S.
dollars.
 
Our country  allocation  decisions were a positive influence over the period. In
particular,  underweighting Japan and the UK proved to be a positive decision as
did an overweight  position in  Continental  Europe.  The primary reason for the
Series'  underperformance  was in stock selection,  particularly in the European
countries. Within Europe, the markets have been very focused, rewarding "growth"
companies,  emphasizing  the very  largest,  but not  necessarily  fundamentally
better value companies.
 
After a strong fourth  quarter,  international  equity markets once again appear
overvalued.   We  maintain  overweight  positions  in  Europe  and  continue  to
underweight  Japan. We continue to favor  Australia and New Zealand.  We hold an
underweight  position  in Latin  America,  especially  in Brazil,  and a neutral
position in the Asian emerging markets.

                                        JNL/PIMCO TOTAL RETURN BOND SERIES
                                        PACIFIC INVESTMENT MANAGEMENT COMPANY
[PACIFIC INVESTMENT MANAGEMENT LOGO]    WILLIAM H. GROSS
 
OBJECTIVE:
 
JNL/PIMCO Total Return Bond Series seeks as its investment  objective to realize
maximum  total  return,  consistent  with  preservation  of capital  and prudent
investment  management  through  investment in a diversified  portfolio of fixed
income securities of varying  maturities.  The average  portfolio  duration will
normally vary within a three- to six-year time frame based on the  sub-adviser's
forecast for interest rates.
 
MONEY MANAGER COMMENTARY:
 
Extreme  volatility  in financial  markets  worldwide  made 1998 one of the most
difficult  years in recent  memory  for fixed  income  managers.  Still,  market
participants able to shift nimbly among all fixed income sectors delivered solid
returns.
 
Following  Russia's  devaluation  in  August,  concern  about  further  currency
devaluations  and weak  Asian  economies  made  investors  wary of taking  risk.
Heightened caution substantially  reduced liquidity in most bond markets.  Yield
premiums  required for holding  non-Treasury  bonds doubled for some  securities
between mid-summer and October as investors fled to safe assets.
 
During the fourth quarter,  50 basis points of interest rate cuts by the Federal
Reserve,  together  with easing by other central  banks,  calmed the markets and
restored  liquidity.  As confidence  returned,  Treasuries lost some appeal as a
safe haven.  Investors shifted money to other bond market sectors and to stocks,
which surged to record highs.  Yield premiums on corporate and emerging  markets
debt narrowed, though they remained well above levels seen earlier in the year.
 
Hopes of  additional  rate cuts in the near term  faded  late in the year in the
face of a strong U.S. economy, reducing demand for Treasuries and driving yields
up 10 to 30 basis  points.  Intermediate  rates  rose most and the  yield  curve
flattened,  as the difference in yield between  two-year and 30-year  maturities
narrowed by 14 basis points.
 
Looking ahead, the Series will:
 
- -    Target portfolio  duration at approximately 0.25 years above it's benchmark
     to capture gains from falling interest rates
 
- -    Emphasize  short/intermediate  maturity  securities which should benefit as
     these rates decline more than long rates
 
- -    Maintain a cautious  approach to risk given continued  market  uncertainty,
     with sector weightings near current levels
 
- -    Underweight  investment-grade  corporates while risks of renewed  financial
     market turmoil persist.

                                  PUTNAM INVESTMENT MANAGEMENT, INC.
[PUTNAM INVESTMENTS LOGO]         C. BETH COTNER
 
OBJECTIVE:
 
JNL/Putnam Growth Series seeks as its investment  objective  long-term growth of
capital.  Since  income  is  not  an  objective,  any  income  generated  by the
investment of this Series'  assets will be incidental to its  objectives.  It is
intended  that  this  Series  will  invest  primarily  in the  common  stocks of
companies believed to have the opportunity for capital growth.
 
MONEY MANAGER COMMENTARY:
 
For much of 1998,  U.S.  equities  performed  extremely  well,  although in late
summer, the market took a decided dip as investors grew skittish about continued
financial and economic  turmoil among  developing  nations.  Stocks recovered as
fall wore on, closing out their fourth  consecutive  year of sparkling  returns.
Large-capitalization  stocks continued to outpace small- and mid-cap stocks, and
companies   whose   operations   were  primarily   domestic  fared  better  than
manufacturers  and  exporters  with links to Asia.  In addition,  growth  stocks
outperformed their value counterparts.
 
The Series  fared well  during the first half of 1998,  benefiting  from  strong
performance in large-cap  technology  stocks. In the tumultuous third quarter of
1998,  the Series lagged the benchmark as holdings in the finance sector dragged
down returns. By fourth quarter,  however,  the Series handily  outperformed the
index due in large part to overweight  exposure to the surging  technology area,
the quarter's  top-performing  sector.  Strong stock  selection  among  consumer
stocks in the fourth quarter was also a major contributor to performance.
 
Overweighting three of the year's  top-performing  sectors,  technology,  health
care and consumer cyclicals, aided returns throughout the period. In technology,
the focus was on software and PC companies,  while in health care,  the emphasis
was on major pharmaceuticals.  In consumer cyclicals, significant positions were
held in major retailers, which were particularly robust in the fourth quarter.
 
Looking  ahead,  the market will likely  remain  volatile,  given the  unsettled
nature  of the  global  economy,  yet the U.S.  continues  to  benefit  from low
inflation and recent  declines in interest  rates.  This unique  environment may
serve as the foundation  for domestic  stability,  helping to maintain  investor
confidence and nurture  growth.  In this  environment,  we are  maintaining  our
disciplined  approach  to stock  selection,  which we  believe  will  result  in
superior  returns  over  time.  The  Series  remains  overweighted  in  consumer
cyclicals  (primarily retail) and in selected  technology and health-care areas.
Sectors  in which  earnings  growth is less  evident  and in which the Series is
underweighted include energy, basic industry, and utilities.

                                  PUTNAM INVESTMENT MANAGEMENT, INC.
[PUTNAM INVESTMENTS LOGO]         ANTHONY I. KREISEL
 
OBJECTIVE:
 
JNL/Putnam Value Equity Series seeks as its investment objective capital growth,
with income as a secondary  objective  by investing  primarily in common  stocks
which the sub-adviser  believes to be undervalued  relative to underlying  asset
value or earnings potential at the time of purchase.
 
MONEY MANAGER COMMENTARY:
 
Throughout  1998,   though  large-cap   stocks   outperformed   their  small-cap
counterparts,   growth  equities  overshadowed  value.  Growth  equities,  which
dominate the S&P 500, have been in favor over the past four years,  a preference
that has made it difficult for value  portfolios to outperform  the Index.  As a
result, the Series  underperformed the S&P 500 Index for the year ended December
31, 1998.
 
The  Series did  benefit  from  market  weighting  in two of the  top-performing
sectors,  utilities and consumer cyclicals.  Strong stock selection in the other
two  (growth-oriented)   top  performers,   technology  and  health  care,  also
contributed to results.
 
The average technology holding in the Series returned over 53% for the year. The
top  contributors  to total  return  for the  year  included  Texas  Instruments
(+90.1%),  IBM (+76.7%),  Intel Corp. (+68.8%),  and Xerox (+59.9%). The Series'
health-care   stocks  rose  42%;  stocks  that   contributed   significantly  to
performance  included  Pharmacia  &  Upjohn  (+54.6%),  American  Home  Products
(+47.2%), and Bristol-Myers Squibb (+41.4%).
 
Overweighting  the more cyclically  oriented basic  industrial,  transportation,
energy, and financial services hindered performance  throughout the year. Money-
center banks underperformed,  with Citigroup and BankAmerica declining 17.8% and
32%, respectively. Specialty chemicals and oil also lagged.
 
Looking  ahead,  while we  anticipate  ongoing  volatility,  we believe that the
Series is well  positioned  to capture the long-term  appreciation  potential of
undervalued but  fundamentally  sound large-cap value companies.  We continue to
emphasize  companies with domestic exposure and minimal Asian earnings exposure,
which is illustrated by our overweight position in utilities and financial.
 
We are emphasizing  companies with  high-quality  earnings  growth,  including a
number of technology companies providing  value-added  increases in productivity
and health-care  companies  demonstrating  earnings growth from new products. We
are also  focused on  companies  benefiting  from merger  activity  and on those
exposed to the U.S. consumer.

                                  STANDARD & POOR'S INVESTMENT ADVISORY
                                  SERVICES, INC.
[STANDARD & POOR'S LOGO]          DAVID M. BLITZER, JOSHUA M. HARARI
 
OBJECTIVE:
 
JNL/S&P  Conservative Growth Series I seeks as its investment  objective capital
growth and current  income.  This Series  pursues its  investment  objective  by
investing  in a  diversified  group of  Series  of the JNL  Series  Trust.  This
investment   concept  is  referred  to  as  a  "fund  of  funds."  Under  normal
circumstances, this Series allocates between 55% and 65% of its assets to Series
that invest  primarily  in equity  securities,  30% to 40% to Series that invest
primarily  in fixed  income  securities,  and 0% to 10% to  Series  that  invest
primarily in money market funds.
 
MONEY MANAGER COMMENTARY:
 
The  Series  commenced  operations  on April 9,  1998 and  returned  4.70%  from
inception  to year-end  1998,  compared  with 2.77% for its  benchmark,  the S&P
Micropal Asset Allocation USA Income Funds Sector Index.
 
The Series'  initial  investment mix included  allocations of 15% each to the T.
Rowe Price/JNL  Mid-Cap Growth Series and the JNL/Eagle Core Equity Series,  10%
each to the JNL/Putnam  Growth Series and JNL/Putnam  Value Equity Series and 5%
each to the JNL Global  Equities  Series and the T. Rowe Price/ JNL  Established
Growth  Series.  The fixed income  portion was allocated as follows:  20% to the
Salomon  Brothers/JNL  Global Bond Series, 15% to the PPM America/JNL High Yield
Bond Series, and 5% to the PPM America/JNL Money Market Series.  This allocation
reflected the long-term  focus of this  investment  program,  but also took into
account the near-term concern about excessive valuations of domestic equities by
allocating  a total of 25% to global  equity and debt  securities.  The domestic
equity allocation reflected a focus on value by allocating to Series that invest
in sectors that had lagged early in 1998, such as mid-cap and value stocks.
 
During the third  quarter,  our concern  shifted  from  overvaluation  of growth
stocks  to worry  that  the U.S.  economy  would  slow  down.  We  adjusted  the
allocation  to reduce  exposure  to  value-oriented  Series that often have high
exposures  to  cyclical,   economically   sensitive  stocks  and  increased  the
allocation  to Series  that focus on growth  stocks that are less  sensitive  to
economic  fluctuations.  The new  allocation  included 15% each to the JNL/Eagle
Core Equity Series and JNL/Putnam Value Equity Series, 10% each to the JNL/Alger
Growth  Series  and  the  JNL  Global  Equities  Series,  and 5% each to the JNL
Aggressive  Growth Series and the T. Rowe Price/JNL  Mid-Cap Growth Series.  The
fixed income  portion of the  portfolio  was  allocated  as follows:  15% to the
Salomon  Brothers/JNL  Global Bond Series,  10% each to the PPM America/JNL High
Yield Bond Series and the Salomon  Brothers/JNL  U.S.  Government & Quality Bond
Series, and 5% to the PPM America/ JNL Money Market Series.
 
The new allocation  positioned the portfolio to participate in the strong market
rally  that began in October as the  Federal  Reserve  aggressively  implemented
three  consecutive  interest rate cuts. The rate cuts allayed  investor fears of
recession. Yet, the rally in the equity markets has benefited growth stocks to a
greater degree than value plays.  Thus, our reliance on equity Series that focus
on growth stocks has proven sound. We remain  confident that over the long term,
a portfolio consistently weighted towards equities will provide superior returns
and help investors meet their financial objectives. We are alert to the elements
of speculative  excess that crop up from time to time and are prepared to adjust
the investment mix to protect the portfolio when deemed necessary.

OBJECTIVE:
 
JNL/S&P  Moderate  Growth  Series I seeks as its  investment  objective  capital
growth and current  income.  This Series  pursues its  investment  objective  by
investing  in a  diversified  group of  Series  of the JNL  Series  Trust.  This
investment   concept  is  referred  to  as  a  "fund  of  funds."  Under  normal
circumstances, this Series allocates between 70% and 80% of its assets to Series
that invest primarily in equity  securities and 20% to 30% to Series that invest
primarily in fixed income securities.
 
MONEY MANAGER COMMENTARY:
 
The  Series  commenced  operations  on April 8,  1998 and  returned  6.30%  from
inception  to year-end  1998,  compared  with 5.45% for its  benchmark,  the S&P
Micropal Asset Allocation USA Balanced Funds Sector Index.
 
The Series'  initial  investment mix included  allocations of 20% to the T. Rowe
Price/JNL  Mid-Cap Growth  Series,  15% each to the JNL/Eagle Core Equity Series
and the JNL/Putnam Growth Series, 10% each to the JNL/Putnam Value Equity Series
and the JNL Global Equities Series, and 5% to the T. Rowe Price/JNL  Established
Growth  Series.  The fixed  income  portion  was  allocated  20% to the  Salomon
Brothers/ JNL Global Bond Series and 5% to the PPM  America/JNL  High Yield Bond
Series.  This  allocation  reflected  the  long-term  focus  of this  investment
program,  but also took into  account  the  near-term  concern  about  excessive
valuations  of domestic  equities by  allocating a total of 30% to global equity
and debt securities.  The domestic equity allocation  reflected a focus on value
by  allocating  to series that invest in sectors  that had lagged  early in 1998
such as mid-cap and value stocks.
 
During the third  quarter,  our concern  shifted  from  overvaluation  of growth
stocks  to worry  that  the U.S.  economy  would  slow  down.  We  adjusted  the
allocation to reduce  exposure to  value-oriented  Series that often have higher
exposures  to  cyclical,   economically   sensitive  stocks  and  increased  the
allocation  to Series  that focus on growth  stocks that are less  sensitive  to
economic  fluctuations.  The new  allocation  included 15% each to the JNL/Eagle
Core Equity Series,  JNL/Putnam  Value Equity Series and the JNL Global Equities
Series,  and 10% each to the JNL/Alger Growth Series,  the JNL Aggressive Growth
Series and the T. Rowe Price/JNL Mid-Cap Growth Series. The fixed income portion
of the  portfolio  was  allocated  as follows:  10% to the Salomon  Brothers/JNL
Global Bond Series,  10% to the PPM America/JNL High Yield Bond Series and 5% to
the Salomon Brothers/JNL U.S. Government & Quality Bond Series.
 
The new allocation  positioned the portfolio to participate in the strong market
rally  that began in October as the  Federal  Reserve  aggressively  implemented
three  consecutive  interest rate cuts. The rate cuts allayed  investor fears of
recession. Yet, the rally in the equity markets has benefited growth stocks to a
greater degree than value plays.  Thus, our reliance on equity Series that focus
on growth stocks has proven sound. We remain  confident that over the long term,
a portfolio consistently weighted towards equities will provide superior returns
and help investors meet their financial objectives. We are alert to the elements
of speculative  excess that crop up from time to time and are prepared to adjust
the investment mix to protect the portfolio when deemed necessary.

OBJECTIVE:
 
JNL/S&P  Aggressive  Growth Series I seeks as its investment  objective  capital
growth.  This  Series  pursues  its  investment  objective  by  investing  in  a
diversified group of Series of the JNL Series Trust. This investment  concept is
referred  to as a "fund of  funds."  Under  normal  circumstances,  this  Series
allocates  between 85% and 95% of its assets to Series that invest  primarily in
equity  securities and 5% to 15% to Series that invest primarily in fixed income
securities.
 
MONEY MANAGER COMMENTARY:
 
The  Series  commenced  operations  on April 8,  1998 and  returned  8.80%  from
inception  to year-end  1998,  compared  with 5.45% for its  benchmark,  the S&P
Micropal Asset Allocation USA Balanced Funds Sector Index.
 
The Series'  initial  investment mix included  allocations of 25% to the T. Rowe
Price/JNL Mid-Cap Growth Series, 20% to the JNL/Putnam Growth Series, 15% to the
JNL/Putnam Value Equity Series, 10% each to the JNL/Eagle Core Equity Series and
the JNL Global Equities Series,  and 5% each to the JNL/ Alger Growth Series and
the JNL Aggressive Growth Series.  The 10% allocated to fixed income investments
was invested in the Salomon  Brothers/JNL  Global Bond Series.  This  allocation
reflected the long-term focus of this  investment  program on equity Series that
emphasize  growth.  But, it also took into account the  near-term  concern about
excessive valuations of domestic equities by allocating a total of 20% to global
equity and debt  securities  and 40% to Series that  invest in sectors  that had
lagged early in 1998, such as mid-cap and value stocks.
 
During the third  quarter,  our concern  shifted  from  overvaluation  of growth
stocks  to worry  that  the U.S.  economy  would  slow  down.  We  adjusted  the
allocation to reduce  exposure to  value-oriented  Series that often have higher
exposures  to  cyclical,   economically   sensitive  stocks  and  increased  the
allocation  to Series  that focus on growth  stocks that are less  sensitive  to

Mid-Cap Growth Series,  and 5% to the JNL/Eagle  SmallCap Equity Series. The 10%
allocated to fixed income Series went into the Salomon  Brothers/JNL Global Bond
Series.

                                  STANDARD & POOR'S INVESTMENT ADVISORY
                                  SERVICES, INC.
[STANDARD & POOR'S LOGO]          DAVID M. BLITZER, JOSHUA M. HARARI
 
OBJECTIVE:
 
JNL/S&P  Very  Aggressive  Growth  Series  I seeks as its  investment  objective
capital growth. Under normal  circumstances,  this Series pursues its investment
objective by investing  100% of its assets in a  diversified  group of Series of
the JNL Series Trust that invest primarily in equity securities. This investment
concept is referred to as a "fund of funds."
 
MONEY MANAGER COMMENTARY:
 
The  Series  commenced  operations  on April 1, 1998 and  returned  11.90%  from
inception  to year-end  1998,  compared  with 5.40% for its  benchmark,  the S&P
Micropal Asset Allocation USA Balanced Funds Sector Index.
 
The Series'  initial  investment  mix  included  allocations  of 25% each to the
JNL/Putnam  Growth Series and the JNL/ Eagle Core Equity Series,  20% to the JNL
Aggressive  Growth Series,  15% to the T. Rowe Price/JNL  Mid-Cap Growth Series,
and 5% each to the JNL/Alger  Growth  Series,  T. Rowe  Price/JNL  International
Equity  Investment  Series and the JNL Global Equities  Series.  This allocation
reflected the long-term focus of this  investment  program on equity Series that
emphasize growth.  Allocations to Series that invest in global equity securities
and Series that invest in sectors that had lagged early in 1998 such as mid-cap,
small-cap and value stocks accounted for 25% of the allocation.
 
During the third  quarter,  our concern  shifted  from  overvaluation  of growth
stocks  to worry  that  the U.S.  economy  would  slow  down.  We  adjusted  the
allocation to reduce  exposure to  value-oriented  Series that often have higher
exposures  to  cyclical,   economically   sensitive  stocks  and  increased  the
allocation  to Series  that focus on growth  stocks that are less  sensitive  to
economic  fluctuations.  The new  allocation  included 25% each to the JNL/Alger
Growth  Series and the JNL Global  Equities  Series,  20% to the JNL  Aggressive
Growth  Series,  10%  each  to the  JNL/Eagle  SmallCap  Equity  Series  and the
JNL/Eagle  Core  Equity  Series,  and 5% each to the T. Rowe  Price/JNL  Mid-Cap
Growth Series and the JNL/Putnam Growth Series.
 
The new allocation  positioned the portfolio to participate in the strong market
rally  that began in October as the  Federal  Reserve  aggressively  implemented
three  consecutive  interest rate cuts. The rate cuts allayed  investor fears of
recession. Yet, the rally in the equity markets has benefited growth stocks to a
greater degree than value plays.  Thus, our reliance on equity Series that focus
on growth stocks has proven sound. We remain  confident that over the long term,
a portfolio consistently weighted towards equities will provide superior returns
and help investors meet their financial objectives. We are alert to the elements
of speculative  excess that crop up from time to time and are prepared to adjust
the investment mix to protect the portfolio when deemed necessary.

                                  SERVICES, INC.
[STANDARD & POOR'S LOGO]          DAVID M. BLITZER, JOSHUA M. HARARI
 
OBJECTIVE:
 
JNL/S&P Equity Growth Series I seeks as its investment objective capital growth.
Under normal  circumstances,  this Series  pursues its  investment  objective by
investing 100% of its assets in a diversified  group of Series of the JNL Series
Trust that primarily  invest in equity  securities.  This investment  concept is
referred to as a "fund of funds."
 
MONEY MANAGER COMMENTARY:
 
The  Series  commenced  operations  on April 13,  1998 and  returned  6.40% from
inception  to year-end  1998,  compared  with 5.45% for its  benchmark,  the S&P
Micropal Asset Allocation USA Balanced Funds Sector Index.
 
The Series' initial investment mix included allocations of 40% to the JNL/Putnam
Value Equity Series, 15% to the T. Rowe Price/JNL Established Growth Series, 10%
each to the T. Rowe  Price/JNL  Mid-Cap Growth  Series,  the  JNL/Putnam  Growth
Series, the JNL/Eagle Core Equity Series and the JNL Global Equities Series, and
5% to the  JNL/Eagle  SmallCap  Equity  Series.  This  allocation  reflected the
long-term  focus of this  investment  program on equity  Series  that  emphasize
growth.  But, it also took into account the near-term  concern  about  excessive
valuations of domestic  equities by allocating  10% to global equity  securities
and 55% to Series that invest in sectors that had lagged early in 1998,  such as
mid-cap, small-cap and value stocks.
 
During the third  quarter,  our concern  shifted  from  overvaluation  of growth
stocks  to worry  that  the U.S.  economy  would  slow  down.  We  adjusted  the
allocation to reduce  exposure to  value-oriented  Series that often have higher
exposures  to  cyclical,   economically   sensitive  stocks  and  increased  the
allocation  to Series  that focus on growth  stocks that are less  sensitive  to
economic  fluctuations.  The new  allocation  included 25% to the JNL/Eagle Core
Equity  Series,  20% each to the JNL Global  Equities  Series and the  JNL/Alger
Growth Series,  15% to the JNL Aggressive Growth Series,  and 10% each to the T.
Rowe Price/JNL Mid-Cap Growth Series and the JNL/Eagle SmallCap Equity Series.
 
The new allocation  positioned the portfolio to participate in the strong market
rally  that began in October as the  Federal  Reserve  aggressively  implemented
three  consecutive  interest rate cuts. The rate cuts allayed  investor fears of
recession. Yet, the rally in the equity markets has benefited growth stocks to a
greater degree than value plays.  Thus, our reliance on equity Series that focus
on growth stocks has proven sound. We remain  confident that over the long term,
a portfolio consistently weighted towards equities will provide superior returns
and help investors meet their financial objectives. We are alert to the elements
of speculative  excess that crop up from time to time and are prepared to adjust
the investment mix to protect the portfolio when deemed necessary.

OBJECTIVE:
 
JNL/S&P  Equity  Aggressive  Growth Series I seeks as its  investment  objective
capital growth. Under normal  circumstances,  this Series pursues its investment
objective by investing  100% of its assets in a  diversified  group of Series of
the JNL Series Trust that primarily invest in equity securities. This investment
concept is referred to as a "fund of funds."
 
MONEY MANAGER COMMENTARY:
 
The  Series  commenced  operations  on April 15,  1998 and  returned  7.50% from
inception  to year-end  1998,  compared  with 6.11% for its  benchmark,  the S&P
Micropal Asset Allocation USA Balanced Funds Sector Index.
 
The Series'  initial  investment  mix  included  allocations  of 25% each to the
JNL/Putnam Growth Series and the T. Rowe Price/JNL Mid-Cap Growth Series, 20% to
the JNL/Eagle Core Equity Series,  10% to the JNL Aggressive Growth Series,  and
5% each to the JNL/Eagle SmallCap Equity Series, T. Rowe Price/JNL International
Equity  Investment  Series,  the JNL Global  Equities  Series and the JNL/Putnam
Value Equity  Series.  This  allocation  reflected the  long-term  focus of this
investment program on equity Series that emphasize growth. Allocations to global
equity  securities  and Series that invest in sectors  that had lagged  early in
1998 such as  mid-cap,  small-cap  and  value  stocks  accounted  for 40% of the
allocation.
 
During the third  quarter,  our concern  shifted  from  overvaluation  of growth
stocks  to worry  that  the U.S.  economy  would  slow  down.  We  adjusted  the
allocation to reduce  exposure to  value-oriented  Series that often have higher
exposures  to  cyclical,   economically   sensitive  stocks  and  increased  the
allocation  to Series  that focus on growth  stocks that are less  sensitive  to
economic  fluctuations.  The new allocation included 25% to the JNL/Alger Growth
Series, 20% each to the JNL Global Equities Series and the JNL/Eagle Core Equity
Series,  15% to the JNL Aggressive Growth Series,  10% to the JNL/Eagle SmallCap
Equity Series and 5% each to the T. Rowe Price/JNL Mid-Cap Growth Series and the
JNL/ Putnam Growth Series.
 
The new allocation  positioned the portfolio to participate in the strong market
rally  that began in October as the  Federal  Reserve  aggressively  implemented
three  consecutive  interest rate cuts. The rate cuts allayed  investor fears of
recession. Yet, the rally in the equity markets has benefited growth stocks to a
greater degree than value plays.  Thus, our reliance on equity Series that focus
on growth stocks has proven sound. We remain  confident that over the long-term,
a portfolio consistently weighted towards equities will provide superior returns
and help investors meet their financial objectives. We are alert to the elements
of speculative  excess that crop up from time to time and are prepared to adjust
the investment mix to protect the portfolio when deemed necessary.

OBJECTIVE:
 
JNL/S&P  Conservative Growth Series II seeks as its investment objective capital
growth and current  income.  This Series  pursues its  investment  objective  by
investing  in a  diversified  group of  Series  of the JNL  Series  Trust.  This
investment   concept  is  referred  to  as  a  "fund  of  funds."  Under  normal
circumstances,  this Series allocates between 60% to 70% of its assets to Series
that invest primarily in equity  securities and 30% to 40% to Series that invest
in fixed income securities.
 
MONEY MANAGER COMMENTARY:
 
The Series  commenced  operations  on April 13,  1998 and  returned  -4.60% from
inception  to year-end  1998,  compared  with 2.77% for its  benchmark,  the S&P
Micropal Asset Allocation USA Income Funds Sector Index.
 
The Series'  initial  investment mix included  allocations of 25% to the Goldman
Sachs/JNL  Growth & Income  Series,  20% to the  Salomon  Brothers/JNL  Balanced
Series,  and 5% each to the JNL/Putnam  Growth Series,  Lazard/JNL Mid Cap Value
Series, JNL Global Equities Series and JNL/Putnam Value Equity Series. The fixed
income portion was allocated 20% to the Salomon Brothers/JNL Global Bond Series,
10%  to  the  JNL/PIMCO  Total  Return  Bond  Series,  and  5%  to  the  Salomon
Brothers/JNL  High Yield Bond Series.  This  allocation  reflected the long-term
focus of this  investment  program,  but also took into  account  the  near-term
concern about excessive  valuations of domestic equities by making extensive use
of equity Series that focus on value as opposed to growth.
 
During the third  quarter,  our concern  shifted  from  overvaluation  of growth
stocks  to worry  that  the U.S.  economy  would  slow  down.  We  adjusted  the
allocation to reduce  exposure to  value-oriented  Series that often have higher
exposures  to  cyclical,   economically   sensitive  stocks  and  increased  the
allocation  to Series  that focus on growth  stocks that are less  sensitive  to
economic fluctuations.  The new allocation included 20% to the Goldman Sachs/JNL
Growth & Income  Series,  15% each to the  JNL/Alliance  Growth  Series  and the
Salomon  Brothers/ JNL Balanced  Series,  10% to the JNL Global Equities Series,
and 5% each to the JNL Aggressive Growth Series and the Lazard/JNL Mid Cap Value
Series. The fixed income portion of the portfolio was allocated as follows:  15%
to the JNL/ PIMCO Total  Return  Bond  Series,  10% to the Salomon  Brothers/JNL
Global Bond Series, and 5% to the Salomon Brothers/ JNL High Yield Bond Series.
 
The  effort to  maintain a  long-term  focus  resulted  in  setbacks  as a broad
pullback in the equity markets took hold in August.  However, by staying true to
the long-term objectives of this Series and with the increased focus on the more
aggressive  equity Series  available,  the portfolio quickly began to recover as
the market rallied in October.  While the overall  performance from inception to
the end of 1998 lagged the Series' benchmark,  the portfolio remained positioned
to continue to benefit from future market  advances.  We remain  confident  that
over the long term, a portfolio  consistently  weighted  towards  equities  will
provide superior returns and help investors meet their financial objectives.  We
are alert to the elements of  speculative  excess that crop up from time to time
and are  prepared to adjust the  investment  mix to protect the  portfolio  when
deemed necessary.

                                  STANDARD & POOR'S INVESTMENT ADVISORY
                                  SERVICES, INC.
[STANDARD & POORS LOGO]           DAVID M. BLITZER, JOSHUA M. HARARI
 
OBJECTIVE:
 
JNL/S&P  Moderate  Growth Series II seeks as its  investment  objective  capital
growth and current  income.  This Series  pursues its  investment  objective  by
investing  in a  diversified  group of  Series  of the JNL  Series  Trust.  This
investment   concept  is  referred  to  as  a  "fund  of  funds."  Under  normal
circumstances, this Series allocates between 70% and 80% of its assets to Series
that invest primarily in equity  securities and 20% to 30% to Series that invest
in fixed income securities.
 
MONEY MANAGER COMMENTARY:
 
The  Series  commenced  operations  on April 13,  1998 and  returned  2.20% from
inception  to year-end  1998,  compared  with 5.45% for its  benchmark,  the S&P
Micropal Asset Allocation USA Balanced Funds Sector Index.
 
The Series'  initial  investment mix included  allocations of 20% to the Goldman
Sachs/JNL Growth & Income Series, 15% each to the Salomon Brothers/JNL  Balanced
Series,  and the Lazard/JNL Mid Cap Value Series,  10% to the JNL/Putnam  Growth
Series,  and 5% each to the  JNL/Alliance  Growth Series,  the T. Rowe Price/JNL
Mid-Cap  Growth Series,  and the JNL Global  Equities  Series.  The fixed income
portion was allocated 15% to the Salomon Brothers/JNL Global Bond Series and 10%
to the Salomon  Brothers/JNL High Yield Bond Series.  This allocation  reflected
the long-term focus of this investment  program,  but also took into account the
near-term  concern about  excessive  valuations  of domestic  equities by making
extensive use of equity Series that focus on value as opposed to growth.
 
During the third  quarter,  our concern  shifted  from  overvaluation  of growth
stocks  to worry  that  the U.S.  economy  would  slow  down.  We  adjusted  the
allocation to reduce  exposure to  value-oriented  Series that often have higher
exposures  to  cyclical,   economically   sensitive  stocks  and  increased  the
allocation  to Series  that focus on growth  stocks that are less  sensitive  to
economic  fluctuations.  The new  allocation  included  20% each to the  Goldman
Sachs/JNL Growth & Income Series and the Salomon  Brothers/JNL  Balanced Series,
15% to the JNL/Alliance Growth Series, and 10% each to the JNL Aggressive Growth
Series, JNL Global Equities Series and the Lazard/ JNL Mid Cap Value Series. The
fixed income  portion of the  portfolio  was  allocated 5% each to the JNL/PIMCO
Total Return Bond Series,  the Salomon  Brothers/JNL  Global Bond Series and the
Salomon Brothers/JNL High Yield Bond Series.
 
The  effort to  maintain a  long-term  focus  resulted  in  setbacks  as a broad
pullback in the equity markets took hold in August.  However, by staying true to
the long-term objectives of this Series and with the increased focus on the more
aggressive  equity Series  available,  the portfolio quickly began to recover as
the market rallied in October.  While the overall  performance from inception to
the end of 1998 lagged the Series' benchmark,  the portfolio remained positioned
to continue to benefit from future market  advances.  We remain  confident  that
over the long term, a portfolio  consistently  weighted  towards  equities  will
provide superior returns and help investors meet their financial objectives.  We
are alert to the elements of  speculative  excess that crop up from time to time
and are  prepared to adjust the  investment  mix to protect the  portfolio  when
deemed necessary.

OBJECTIVE:
 
JNL/S&P  Aggressive  Growth Series II seeks as its investment  objective capital
growth.  This  Series  pursues  its  investment  objective  by  investing  in  a
diversified group of Series of the JNL Series Trust. This investment  concept is
referred  to as a "fund of  funds."  Under  normal  circumstances,  this  Series
allocates  between 85% and 95% of its assets to Series that invest  primarily in
equity  securities  and  5% to  15%  to  Series  that  invest  in  fixed  income
securities.
 
MONEY MANAGER COMMENTARY:
 
The  Series  commenced  operations  on April 13,  1998 and  returned  0.50% from
inception  to year-end  1998,  compared  with 5.45% for its  benchmark,  the S&P
Micropal Asset Allocation USA Balanced Funds Sector Index.
 
The Series' initial investment mix included allocations of 25% to the Lazard/JNL
Mid Cap Value Series,  20% to the Goldman Sachs/JNL Growth & Income Series,  10%
each to the Salomon Brothers/JNL  Balanced Series,  JNL/Putnam Growth Series and
the JNL Global Equities Series,  and 5% each to the JNL/ Alliance Growth Series,
the T. Rowe Price/JNL Mid-Cap Growth Series,  and the Lazard/JNL Small Cap Value
Series.  The  fixed  income  portion  was  allocated  5%  each  to  the  Salomon
Brothers/JNL Global Bond Series and to the Salomon  Brothers/JNL High Yield Bond
Series.  This  allocation  reflected  the  long-term  focus  of this  investment
program,  but also took into  account  the  near-term  concern  about  excessive
valuations  of domestic  equities by making  extensive use of equity Series that
focus on value as opposed to growth.
 
During the third  quarter,  our concern  shifted  from  overvaluation  of growth
stocks  to worry  that  the U.S.  economy  would  slow  down.  We  adjusted  the
allocation to reduce  exposure to  value-oriented  Series that often have higher
exposures  to  cyclical,   economically   sensitive  stocks  and  increased  the
allocation  to Series  that focus on growth  stocks that are less  sensitive  to
economic fluctuations.  The new allocation included 20% each to the JNL/Alliance
Growth  Series and the  Goldman  Sachs/ JNL Growth & Income  Series,  15% to the
Lazard/JNL Mid Cap Value Series,  10% each to the JNL Aggressive  Growth Series,
the Lazard/JNL  Small Cap Value Series,  the JNL Global  Equities Series and the
Salomon  Brothers/JNL  Balanced  Series.  The 5%  fixed  income  portion  of the
portfolio was allocated to the Salomon Brothers/JNL Global Bond Series.
 
The  effort to  maintain a  long-term  focus  resulted  in  setbacks  as a broad
pullback in the equity markets took hold in August.  However, by staying true to
the long-term objectives of this Series and with the increased focus on the more
aggressive  equity Series  available,  the portfolio quickly began to recover as
the market rallied in October.  While the overall  performance from inception to
the end of 1998 lagged the Series' benchmark,  the portfolio remained positioned
to continue to benefit from future market  advances.  We remain  confident  that
over the long term, a portfolio  consistently  weighted  towards  equities  will
provide superior returns and help investors meet their financial objectives.  We
are alert to the elements of  speculative  excess that crop up from time to time
and are  prepared to adjust the  investment  mix to protect the  portfolio  when
deemed necessary.

                                  STANDARD & POOR'S INVESTMENT ADVISORY
                                  SERVICES, INC.
[STANDARD AND POORS LOGO]         DAVID M. BLITZER, JOSHUA M. HARARI
 
OBJECTIVE:
 
JNL/S&P  Equity  Growth  Series  II seeks as its  investment  objective  capital
growth. Under normal circumstances, this Series pursues its investment objective
by  investing  100% of its  assets in a  diversified  group of Series of the JNL
Series Trust that primarily invest in equity securities. This investment concept
is referred to as a "fund of funds."
 
MONEY MANAGER COMMENTARY:
 
The  Series  commenced  operations  on April 13,  1998 and  returned  0.40% from
inception  to year-end  1998,  compared  with 5.45% for its  benchmark,  the S&P
Micropal Asset Allocation USA Balanced Funds Sector Index.
 
The Series'  initial  investment  mix  included  allocations  of 25% each to the
Lazard/JNL  Mid Cap  Value  Series  and the  Goldman  Sachs/JNL  Growth & Income
Series,  15% each to the  JNL/Putnam  Growth  Series  and the  JNL/Putnam  Value
Series,  10% to the JNL Global Equities Series,  and 5% each to the JNL/Alliance
Growth  Series  and the  Lazard/  JNL Small Cap Value  Series.  This  allocation
reflected the long-term  focus of this  investment  program,  but also took into
account the near-term concern about excessive valuations of domestic equities by
making extensive use of equity Series that focus on value as opposed to growth.
 
During the third  quarter,  our concern  shifted  from  overvaluation  of growth
stocks  to worry  that  the U.S.  economy  would  slow  down.  We  adjusted  the
allocation to reduce  exposure to  value-oriented  Series that often have higher
exposures  to  cyclical,   economically   sensitive  stocks  and  increased  the
allocation  to Series  that focus on growth  stocks that are less  sensitive  to
economic fluctuations.  The new allocation included 20% each to the JNL/Alliance
Growth Series,  the Lazard/JNL Mid Cap Value Series and the JNL Global  Equities
Series,  15% each to the JNL Aggressive  Growth Series and the Goldman Sachs/JNL
Growth & Income Series, and 10% to the Lazard/JNL Small Cap Value Series.
 
The  effort to  maintain a  long-term  focus  resulted  in  setbacks  as a broad
pullback in the equity markets took hold in August.  However, by staying true to
the long-term objectives of this Series and with the increased focus on the more
aggressive  equity Series  available,  the portfolio quickly began to recover as
the market rallied in October.  While the overall  performance from inception to
the end of 1998 lagged the Series' benchmark,  the portfolio remained positioned
to continue to benefit from future market  advances.  We remain  confident  that
over the long term, a portfolio  consistently  weighted  towards  equities  will
provide superior returns and help investors meet their financial objectives.  We
are alert to the elements of  speculative  excess that crop up from time to time
and are  prepared to adjust the  investment  mix to protect the  portfolio  when
deemed necessary.

                                  STANDARD & POOR'S INVESTMENT ADVISORY
                                  SERVICES, INC.
[STANDARD AND POORS LOGO]         DAVID M. BLITZER, JOSHUA M. HARARI
 
OBJECTIVE:
 
JNL/S&P Equity  Aggressive  Growth Series II seeks as its  investment  objective
capital growth. Under normal  circumstances,  this Series pursues its investment
objective by investing  100% of its assets in a  diversified  group of Series of
the JNL Series Trust that primarily invest in equity securities. This investment
concept is referred to as a "fund of funds."
 
MONEY MANAGER COMMENTARY:
 
The  Series  commenced  operations  on April 13,  1998 and  returned  3.60% from
inception  to year-end  1998,  compared  with 5.45% for its  benchmark,  the S&P
Micropal Asset Allocation USA Balanced Funds Sector Index.
 
The Series'  initial  investment  mix  included  allocations  of 25% each to the
Lazard/JNL  Mid Cap  Value  Series  and the  Goldman  Sachs/JNL  Growth & Income
Series,  15% each to the  JNL/Alliance  Growth Series and the JNL/ Putnam Growth
Series,  10% to the JNL  Global  Equities  Series,  and 5%  each to the T.  Rowe
Price/JNL Mid-Cap Growth Series and the Lazard/JNL Small Cap Value Series.  This
allocation  reflected the long-term focus of this investment  program,  but also
took into account the near-term  concern about excessive  valuations of domestic
equities by making extensive use of equity Series that focus on value as opposed
to growth.
 
During the third  quarter,  our concern  shifted  from  overvaluation  of growth
stocks  to worry  that  the U.S.  economy  would  slow  down.  We  adjusted  the
allocation to reduce  exposure to  value-oriented  Series that often have higher
exposures  to  cyclical,   economically   sensitive  stocks  and  increased  the
allocation  to Series  that focus on growth  stocks that are less  sensitive  to
economic  fluctuations.  The new  allocation  included  25% to the  JNL/Alliance
Growth  Series,  20% each to the  Lazard/  JNL Mid Cap Value  Series and the JNL
Global Equities Series, 15% to the JNL Aggressive Growth Series, and 10% each to
the Goldman  Sachs/JNL Growth & Income Series and the Lazard/JNL Small Cap Value
Series.
 
The  effort to  maintain a  long-term  focus  resulted  in  setbacks  as a broad
pullback in the equity markets took hold in August.  However, by staying true to
the long-term objectives of this Series and with the increased focus on the more
aggressive  equity Series  available,  the portfolio quickly began to recover as
the market rallied in October.  While the overall  performance from inception to
the end of 1998 lagged the Series' benchmark,  the portfolio remained positioned
to continue to benefit from future market  advances.  We remain  confident  that
over the long-term,  a portfolio  consistently  weighted  towards  equities will
provide superior returns and help investors meet their financial objectives.  We
are alert to the elements of  speculative  excess that crop up from time to time
and are  prepared to adjust the  investment  mix to protect the  portfolio  when
deemed necessary.

                                  GOLDMAN SACHS ASSET MANAGEMENT
                                  GREG GIGLIOTTI, THOMAS S. PRICE,
[GOLDMAN SACHS LOGO]              LAWRENCE S. SIBLEY, KARMA WILSON
 
OBJECTIVE:
 
Goldman  Sachs/JNL  Growth & Income  Series  seeks as its  investment  objective
long-term  growth of capital and growth of income through  investments in equity
securities  that  are  considered  to  have  favorable   prospects  for  capital
appreciation and/or dividend paying ability.
 
MONEY MANAGER COMMENTARY:
 
The year's positive momentum was inspired largely by the Federal Reserve Board's
successive  rate cuts,  which  eased the credit  crunch in capital  markets  and
relieved  concerns about global  financial  conditions.  Notably,  gains for the
entire year were  attributable  to a narrow segment of the market;  the top five
stocks in the S&P 500 Index ("Index")  created 24% of the total return,  and the
top fifty stocks  accounted  for 82% of the total return.  Furthermore,  the top
decile generated  approximately 70% of the 1998 total return and mega-cap growth
stocks  led the  pack.  The  final  results:  the  Index  closed  the year up an
impressive 28.58%,  significantly  outperforming smaller  capitalization indices
such as the  Russell  Midcap  Index,  which was up only  10.1% for the same time
period.
 
Investors  also favored growth versus value  investing  during most of the year,
with the S&P 500/BARRA  Growth Index  posting a 42.1% return at year-end  versus
the S&P  500/BARRA  Value  Index,  which  returned  only 13.8% for the same time
period.
 
The Series  employs a  value-oriented  strategy that seeks  long-term  growth of
capital. This strategy,  combined with our bias for  mid-capitalization  stocks,
detracted  from   performance   during  the  year.   However,   performance  was
attributable,  to a greater extent, to stocks we did not own.  Specifically,  we
lost ground relative to the Index based on lack of participation in the enormous
gains of blue-chip  computer  software  companies (the majority of their returns
ranged from 20%-60% for the quarter),  multi-national consumer product companies
(returns  ranged  between  14%-58%) and mega-cap  pharmaceutical  companies  and
electronic media stocks (except for two stocks, returns ranged between 17%-95%).
 
During the year, we increased  the number of holdings in the  portfolio  from 34
holdings  in May  to 88  holdings  at  year-end.  By  broadening  the  portfolio
exposures,  we  diminished  the  size  and  number  of  industry  bets  and  the
concentration  of the  largest  holdings.  We  focused  our new  investments  in
large-cap  segments of the market (>$5 billion) and raised the median market cap
of the portfolio from $9 billion in May to $16 billion at year-end.
 
Since inception,  the Series returned -9.31%,  underperforming the S&P 500 Index
return of 18.61% during the same time period.  The Series  currently  sells at a
significant  discount  relative  to  the  Index,  and  we  anticipate  that  our
discounted valuation  investments should re-attract capital and drive returns to
more  traditional  levels.  We  believe  that the steps we have taken to improve
diversification will provide returns more in line with the Index going forward.
 
In all environments,  we perform rigorous,  firsthand research into stocks which
trade  at a  discount  to  the  market  and  their  peers  due to  obscurity  or
uncertainty.  We aim to exploit anomalies by investigating  what is undiscovered
or  misunderstood  by the  marketplace.  We firmly believe that our disciplined,
value-based  approach  has  the  potential  to  deliver  strong  returns  to the
long-term investor.

                                  LAZARD/JNL SMALL CAP VALUE SERIES
                                  LAZARD ASSET MANAGEMENT
                                  HERBERT W. GULLQUIST
  [LAZARD ASSET MANAGEMENT LOGO]  EILEEN ALEXANDERSON
 
OBJECTIVE:
 
Lazard/JNL Small Cap Value Series is a non-diversified  Series that seeks as its
investment  objective  capital  appreciation  by  investing  primarily in equity
securities of companies  with market  capitalizations  under $1 billion that are
believed by the sub-adviser to be inexpensively priced relative to the return on
total capital or equity.
 
MONEY MANAGER COMMENTARY:
 
Although  the  Russell  2000  Index  lost  ground in 1998,  small  caps  rallied
impressively  over the  fourth  quarter  -- up over 30%  since the  October  8th
trough,  with a 16.4% gain in the fourth quarter.  Historically  low valuations,
declining  interest rates,  sanguine  earnings  expectations,  and positive flow
funds  have set the  stage for the  current  small cap  rally.  Although  larger
capitalization  equities still capture the bulk of investor  attention and money
flows,  strong  earnings  expectations  for  small cap  companies  have been the
catalyst  for  attracting  new money into the asset class.  Consumer  confidence
remained robust in December,  a sign that household  spending,  and by extension
overall  economic  growth,  should  remain  strong in early 1999.  And, with the
exception of energy,  all sectors of the market generated  positive returns over
the fourth quarter,  with technology and healthcare  producing the best absolute
gains.
 
Despite the  current  healthy  environment,  the  collective  faith of small cap
investors was severely  challenged  during 1998. The Russell 2000 Index was down
2.55% for the year,  a drop that was  especially  notable  when  compared to the
large cap stocks, as measured by the S&P 500, which was up 28.58%. As the larger
stocks once again asserted their dominance  throughout 1998, small cap investors
were able to take comfort in some of the merger and acquisition activity, as the
deep discounts that some small cap stocks are selling at has begun to be noticed
by strategic  buyers.  In fact, many of the stocks in the Series  benefited from
such  takeovers.  Amidst the rapid shifts in the market during 1998,  the Series
benefited from strong stock  selection in the  telecommunications  and utilities
sectors,  and was  hurt by weak  stock  selections  in the  technology,  health,
finance, and consumer services sectors.
 
During the last quarter,  technology stocks,  including Electronics for Imaging,
Lattice  Semiconductor,  and VLSI  Technology,  were  among our best  performing
stocks.  Electronics for Imaging,  which develops products and technologies that
enable  digital  color  printing over  computer  networks,  profited from robust
corporate demand, while semiconductor companies, including Lattice Semiconductor
and VLSI Technology,  profited from strong  PC-related and wireless end markets,
as well as from overall low inventory  levels.  Economically  sensitive  stocks,
like Omniquip  International  and Belden Inc.,  outperformed over the quarter as
fears of global recession subsided.  Meanwhile,  consumer  discretionary  stocks
were among both our best and worst  performers  over the  quarter.  First Brands
Corp., a consumer goods company (GLAD bags, Handiwipes,  cat litter),  benefited
from strong  domestic  sales,  a favorable  sales mix, and more  normalized  raw
material  prices.  The company's  results were also driven by performance of its
acquirer, Clorox. Wet Seal and Talbots reported  better-than-expected results as
sales  levels   returned  to  normal  when  the  weather   normalized  and  good
merchandising paid off. Cole National  Corporation,  however, a specialty retail
service  company  operating in both optical and gift  businesses,  suffered from
challenges at Pearle Vision,  one of the company's  optical  retail  operations.
Pearle's  results have fallen short of expectations  due, in part, to aggressive
store growth by competitors and changes in government reimbursement. Many of our
energy stocks,  including Tuboscope Inc. and Vintage Petroleum,  were victims of
plunging oil prices, which now hover at 12-year lows.
 
1998's  turbulence  brought  many  higher-priced  stocks  down to our  valuation
levels.  As well,  amidst  continuing  volatility,  heightened  competition will
likely  forge many new,  interesting  unions,  making the  selection  of choice,
undervalued  small cap companies a savvy investment  decision.  Looking forward,
1999 promises plenty of volatility, but with it, many opportunities.

                                  LAZARD/JNL MID CAP VALUE SERIES
                                  LAZARD ASSET MANAGEMENT
                                  HERBERT W. GULLQUIST
  [LAZARD ASSET MANAGEMENT LOGO]  EILEEN ALEXANDERSON
 
OBJECTIVE:
 
Lazard/JNL  Mid Cap Value Series is a  non-diversified  Series that seeks as its
investment  objective  capital  appreciation  by  investing  primarily in equity
securities of companies  with market  capitalizations  in the range of companies
represented  in  the  Russell  Midcap  Index  that  the  sub-adviser   considers
inexpensively priced relative to the return on total capital or equity.
 
MONEY MANAGER COMMENTARY:
 
After a volatile third quarter,  mid cap indices  rallied in the fourth quarter,
with the S&P Mid Cap Index  outperforming both the S&P 500 Index and the Russell
2000  Index of small cap  companies.  The  market's  momentum  was fueled by the
Federal  Reserve's  three  interest-rate  cuts,  signs that the Asian  financial
crisis may be turning a corner,  surging merger and  acquisition  activity,  the
resilience of the U.S.  economy,  and a rally among technology  stocks.  Markets
seemed impervious to the bombing of Iraq, the impeachment of President  Clinton,
and numerous profit warnings. Consumer confidence remained robust in December, a
sign that household spending,  and by extension overall economic growth,  should
remain strong in early 1999.  With the  exception of energy,  all sectors of the
mid cap  market  generated  positive  returns  over  the  fourth  quarter,  with
technology producing the best absolute gains.
 
Despite the current healthy environment, mid cap stocks proved to be a less than
stellar asset class in 1998,  with the Russell  Midcap Index being up 10.10% for
the year,  especially when compared to large cap stocks,  as measured by the S&P
500 Index, which was up 28.58%. In the fourth quarter,  the Russell Midcap Index
rebounded 18.44%,  with a real divergence  between value and growth that was due
largely to the mania for anything remotely connected to the Internet. Amidst the
rapid shifts in the market during 1998,  the Series  benefited from strong stock
selection   in   the   consumer   durables,    producer    manufacturing,    and
telecommunications  sectors,  and  was  hurt  by weak  stock  selections  in the
consumer discretionary, health, technology, and process sectors.
 
Technology  stocks,  including  Altera Corp.,  Advanced Micro  Devices,  and NCR
Corp.,  benefited from strong  consumer and corporate  demand and were among our
best  performing   stocks,   especially   over  the  fourth  quarter.   Consumer
discretionary stocks, including TJX Companies (T.J. Maxx and Marshalls), Circuit
City,  and Saks  Inc.,  also  outperformed  in the wake of  better-than-expected
Christmas sales trends.  Financial  companies were among both our best and worst
performing  stocks.  Ambac  Financial,  Waddell  & Reed,  and  Heller  Financial
benefited  from  lower  interest  rates  and a sense  of  greater  international
stability.  American  Bankers  Insurance  Group  and  Union  Planters,  however,
underperformed over the quarter.  Several of our energy holdings,  including R&B
Falcon, Noble Affiliates,  and Cooper Cameron, were victims of oil prices, which
now hover at 12-year  lows.  Some of our utility  holdings,  including  Illinova
Corp. and Nipsco Industries, also underperformed as the market rallied.
 
1998's  turbulence  brought  many  higher-prices  stocks  down to our  valuation
levels.  As well,  amidst  continuing  volatility,  heightened  competition will
likely  forge many new,  interesting  unions,  making the  selection  of choice,
undervalued mid cap companies a savvy investment decision. Looking forward, 1999
promises plenty of volatility, but with it, many opportunities.

[PPM AMERICA LOGO]                TEAM MANAGEMENT
 
OBJECTIVE:
 
PPM  America/JNL  Balanced Series seeks as its investment  objective  reasonable
income,  long-term  capital growth and  preservation of capital.  It is intended
that this Series will invest in common stocks and fixed income securities,  with
emphasis on income-producing  securities which appear to have some potential for
capital enhancement.
 
MONEY MANAGER COMMENTARY:
 
Despite a dip in the third  quarter,  the U.S.  equity market  produced  another
extremely  strong return in 1998.  The stock market was driven  primarily by the
"Nifty 50" segment of the market;  i.e. by stocks of very large  companies  with
extremely high  valuations.  The U.S.  fixed income market also posted  positive
returns as interest rates fell during the year. The overall  decline in interest
rates was  driven by  short-term  interest  rate  reductions  engineered  by the
Federal Reserve and a flight to quality due to the deepening  economic crisis in
the emerging markets.
 
The  valuation of the broad market has become very  expensive as a result of the
extremely  strong market  returns over the last few years (the Standard & Poor's
500 Stock Index  produced its fourth  consecutive  20+% annual  return in 1998.)
There are also increasing  signs of speculative  excess in the stock market.  We
use value-oriented strategies in managing the Series. As a result of the overall
market's unattractive level, we have maintained a fairly even allocation between
equity and fixed income securities.
 
The  stock  selection  philosophy  that  guides  the  management  of the  equity
component  of the Series is  value-oriented.  Therefore,  even within an overall
market of stretched valuation,  we remain committed to identifying  attractively
priced sectors and  securities.  The equity portion of the Series' assets have a
lower-than-market  price/  earnings ratio  (compared to the S&P 500 Index) and a
higher-than-market  dividend  yield.  The equity  component is  overweighted  in
stocks of telecommunications, retail/apparel, financial, auto and transportation
companies.  It is  significantly  underweighted  in stocks  of  health  care and
technology  companies.  The fixed income portion of the Series is managed with a
duration-neutral,  relative value framework.  With an interest rate risk profile
similar to the overall bond market,  the fixed income  portion of the Series was
overweighted  (at  year-end)  in  U.S.  Government  securities  and  high  yield
corporate bonds and underweighted in investment grade corporate bonds.
 
The Series produced a return of 10.06% for 1998. This compares to 28.58% for the
S&P 500 Index and 8.69% for the Lehman Brothers Aggregate Bond Index.

                                  PPM AMERICA, INC.
[PPM AMERICA LOGO]                TEAM MANAGEMENT
 
OBJECTIVE:
 
PPM America/JNL High Yield Bond Series seeks as its investment  objective a high
level  of  current  income;  its  secondary   investment  objective  is  capital
appreciation  by  investing  in  fixed  income  securities,   with  emphasis  on
higher-yielding, higher-risk, lower-rated or unrated corporate bonds.
 
MONEY MANAGER COMMENTARY:
 
The U.S. high yield market, as measured by the Lehman Brothers High Yield Index,
returned  1.87%  in  1998,  a  performance   which  lagged  all  other  domestic
fixed-income   classes  and  broke  its  two-year   string  of   outperformance.
Higher-grade tiers of the bond market  outperformed,  reversing previous trends,
as interest  rates fell around 100 basis  points  across the yield  curve.  High
yield  outperformed  in the period  through  July as stable  interest  rates,  a
healthy economy, low default rates, and strong investor demand carried over from
1997. In August, however, the deepening economic crises in Asia and Russia began
to pose a realistic risk of global recession.  The market fell 5.52% that month,
its  worst  loss  since  September  1990,  amid a flight  to  quality  which was
compounded  by selling from some mutual  funds and hedge  funds.  A recovery was
sparked in September  when the Federal  Reserve began to cut interest  rates and
the G-7  funded a loan  package to help  stabilize  emerging  markets.  In fact,
November's gain of 5.15% was one of the index's best performances  ever, but not
enough to offset the summer's  losses.  Despite the turmoil,  however,  the high
yield market continued to grow at a rapid rate in 1998. New issue volume reached
record levels for the second year in a row as the principal  amount of new bonds
issued jumped 18.7% to $141 billion.
 
Our  approach to managing  the Series is based on  relative  value.  We focus on
purchasing  individual  securities  which are  attractively  priced and have the
potential to outperform the benchmark, within the context of industry weightings
which are derived  from the same  factors.  In 1998,  this  approach  lead to an
approximately  neutral  weighting  of  double-B  versus  single-B  credits,  but
security and industry  selection were generally  defensive,  particularly in the
third quarter.
 
The Series finished 1998 with a total return of 3.84%,  outperforming the Lehman
Brothers  High Yield Index by 197 basis points.  The Lipper High Yield  Universe
lost  0.44% and the  Morningstar  High Yield  Index  lost 0.42% in 1998,  so the
Series  also   strongly   outperformed   them  by  428  and  426  basis  points,
respectively.  The Series' performance  advantage was primarily  attributable to
security selection as well as favorable industry and asset-class allocations.
 
We expect the high yield market to perform closer to historical averages in 1999
since the fundamental  underpinnings of a growing  economy,  low interest rates,
and low default rates appear to remain in place.  The Lehman Brothers High Yield
Index has returned an annual average 13.05% over the last 15 years.  Major risks
include the  possibility of a recession,  although the U.S.  economy looks quite
strong  at  the  moment,  and  further  effects  from  economic  crises  abroad.
Additionally,   single-B  and  lower-rated   credits  (including  unrated)  have
accounted  for more than 2/3 of new issue flow for three  years in a row.  While
the highest  returns often come from the lower quality  tiers,  this mix is also
changing the market's risk profile and will undoubtedly have an impact on future
performance.

[SALOMON BROTHERS ASSET MANAGEMENT LOGO]
                                           SALOMON BROTHERS/JNL BALANCED SERIES 
                                           SALOMON BROTHERS ASSET MANAGEMENT INC
                                           GEORGE WILLIAMSON
                                  
OBJECTIVE:
 
Salomon  Brothers/JNL  Balanced  Series  seeks to  obtain  above-average  income
(compared to a portfolio entirely invested in equity securities). As a secondary
objective,  the Series seeks to take  advantage of  opportunities  for growth of
capital and income. The Series seeks to achieve its objectives primarily through
investments  in a broad  variety of  securities,  including  equity  securities,
fixed-income securities and short-term obligations.
 
MONEY MANAGER COMMENTARY:
 
The Series  returned  5.91% since  inception,  versus 13.01% for the 50% Salomon
Smith   Barney   Broad   Investment   Grade  Bond   Index/50%   S&P  500  Index.
Underperformance  of the Series for the period was  attributed  to its continued
conservative equity allocation and value style. In an environment  characterized
by extremely momentum driven markets, we perform less than the market due to our
value style.
 
The equity market finished its fourth  consecutive  year of returns in excess of
20%  with  the S&P  500  returning  28.58%.  Investors  experienced  significant
volatility  during the year as the S&P 500 increased more than 20% through early
July,  only to fall back into  negative  territory in the  beginning of October.
Worldwide  political  and economic  turmoil  resulted in a loss of confidence by
U.S.  equity  investors  late  in the  summer.  The  collapse  of the  financial
structure in Russia,  although not totally unexpected,  coupled with the ongoing
crisis in Asia,  caused a number of financial  institutions to take charge offs,
and led to a "flight to quality" that exposed a number of over  leveraged  hedge
funds financial difficulties.
 
By early Fall,  the Federal  Reserve came to the market's  rescue by cutting the
federal funds rate and discount  rate. As the stock and credit  markets  rallied
after the Federal  Reserve rate cut, the need for the safety of  Treasuries  was
reduced.  Spread  sectors  of the market  such as  mortgage  backed  securities,
corporate  bonds and  asset  backed  securities  all did  better as the  overall
reduction in the global risk premium led to an  improving  disposition  in those
markets.  Two additional interest rate reductions  increased investor confidence
and provided  liquidity to fuel the market's strong fourth quarter  performance.
Large-cap  growth stocks were the only stocks that really drove  performance for
the year 1998. We anticipate security markets will be more subdued in 1999.
 
In  the  equity  portion  of  our  portfolio,  we  maintained  our  strategy  to
significantly  overweight those companies where we had the greatest  conviction,
i.e. position and  concentration.  We kept our overweight stance in the consumer
and  financial  sectors  with such new  additions  as  PepsiCo,  Avon  Products,
BankAmerica,  and Pharmacia & Upjohn. We were positioned  conservatively for the
year, to give  investors  the upside  potential  through the Series  exposure to
equities while limiting downside risk.
 
We expect value stocks to receive  better  valuation in the current year as well
as better  performance.  We  believe  the  portfolio  is in a good  position  to
withstand  further market  declines if any are experienced and to participate in
market appreciation.
 
After seven years of  uninterrupted  growth,  the U.S. economy faces a period of
slowing  expansion and  threatened  instability.  Although key areas of economic
activity remain buoyant, gradual slowing remains a likely scenario for 1999. The
Federal   Reserve   will   probably   condition   further   easing  on   renewed
intensification  of  financial  stress of  evidence  that demand  pressures  are
receding.
 
We expect  interest rates to generally move lower in the first few months of the
year,  followed by a gradual rise through the end of 1999.  With the expectation
of further Federal Reserve  easing,  we look for the yield curve to steepen.  As
such,  long-term  bonds may  stabilize  in a range  centered on 5% as  long-term
inflation expectations fall.

OBJECTIVE:
 
Salomon Brothers/JNL Global Bond Series seeks as its investment objective a high
level of current income. As a secondary objective,  the Series will seek capital
appreciation.  The Series  seeks to achieve its  objectives  by  investing  in a
globally  diverse  portfolio  of fixed  income  investments  and by  giving  the
sub-adviser broad discretion to deploy the Series' assets among certain segments
of the fixed income market that the sub-adviser believes will best contribute to
achievement of the Series' investment objectives.
 
MONEY MANAGER COMMENTARY:
 
The Series returned 2.46% for 1998 versus 5.15% for the Lipper Variable Products
Global  Income  Funds  category  and 8.72% for the Salomon  Smith  Barney  Broad
Investment Grade Bond Index.  Underperformance  of the Series was largely due to
its  exposure to high yield and  emerging  markets  debt  during the  unexpected
credit crisis in the summer of 1998.
 
For  bonds,  1998 was a  mixture  of good and bad  news.  The good news was that
interest  rates  fell  approximately  1% across  the  yield  curve.  Though  low
inflation did contribute to lower bond yields,  exogenous factors such as equity
market  fears,  default  fears and  expectations  of spreading  global  economic
weakness gave investors sufficient reasons to seek only the safety and liquidity
of the Treasury  sector.  The bad news came for any bond that wasn't a Treasury,
as yield spreads across all sectors of the domestic bond universe widened toward
unexplainable  and  unsustainable  levels.  High yield bonds and emerging market
debt suffered through their worst performances in years. This was largely due to
the global spread rout.
 
Early in 1998,  domestic  demand  readings  in the U.S.  remained  exceptionally
healthy,  benefitting from low interest rates, generation-low unemployment rates
and sky-high consumer  confidence.  Lower quality high yield bonds outperformed,
so the Series reaped the profits and upgraded  into  relatively  higher  quality
bonds. The Series  maintained a neutral duration relative to the Lehman Brothers
Aggregate  Bond  Index  and  added  to  its  overweighting  in  mortgage  backed
securities.  Discount  coupon  mortgages  and  seasoned  pass-through  mortgages
continued to be selected as they  offered a more  attractive  convexity  profile
than higher coupon securities.
 
The Series  maintained it's  weightings in the high yield sector  throughout the
second quarter, as credit fundamentals remained favorable.  We continued to seek
opportunities  to upgrade credit quality and moved to a more defensive  position
within the sector.  In the emerging markets sector of the portfolio,  we lowered
our  exposure  to Russia  and added  Bulgaria  and Peru.  Mexico  and  Argentina
continued to be core holdings as their fundamentals remained strong.
 
During the third quarter,  heightened global market volatility caused the Series
to commit to a more  defensive  stance in its high  yield  sector  and lower its
allocations  to the emerging  markets debt sector.  We continued to decrease the
Series'  exposure to Russia and increase its position in Argentina and Mexico as
fundamentals appeared more favorable. The Series continued to favor discount and
coupon  mortgage  backed  securities  in the  investment  grade  portion  of the
portfolio.
 
During the fourth  quarter,  high yield and emerging  debt markets  snapped back
strongly when it became  apparent to investors that the financial  market crisis
was stabilizing.  Bold steps taken by the Federal Reserve in lowering short-term
interest rates and restoring  liquidity in the markets began to put investors at
ease.  We  maintained  our stance in the high yield  sector of the  portfolio as
credit  spreads  had room to  improve  and  interest  rates  slashed by 75 basis
points.  We increased our  allocations in the emerging  markets debt sector from
15% to 20% as the  markets  have  recovered  some 20% since  their lows in early
September.
 
Investor  optimism and recent  economic  data  suggest that the U.S.  economy is
sailing into the new year.  As booming  sectors  moderate  and  external  growth
continues to fade, the current expansion will slow  perceptibly.  The optimistic
view assumes that the rest of the world holds together.  Outside the U.S., where
the  main  threat  to  domestic   stability   first  emerged,   conditions  have
deteriorated since the Federal Reserve's last rate cut. This backdrop leaves the
Federal  Reserve  in a  watchful  state,  despite  the  complacency  of  today's
marketplace  and strong  fourth-quarter  GDP growth.  Near-term job and economic
growth probably will remain fairly buoyant, given the boost from lower commodity
prices,  warm  weather and the fresh rise in the equity  market.  However,  with
inflation pressures in remission,  the Federal Reserve will have ample leeway to
renew its rescue efforts in 1999 if necessary.
 
We remain  optimistic about the high yield market, as interest rates are low and
credit spreads have room to improve. While there will be bumps along the way, we
expect emerging debt to outperform the U.S. investment grade market in 1999.

                                     SALOMON BROTHERS ASSET MANAGEMENT INC
                                     PETER J. WILBY
 
OBJECTIVE:
 
Salomon Brothers/JNL High Yield Bond Series seeks to maximize current income. As
a secondary objective,  the Series seeks capital appreciation.  The Series seeks
to achieve its objectives by investing  primarily in a diversified  portfolio of
high  yield  fixed-income  securities  that offer a yield  above that  generally
available  on debt  securities  in the four  highest  rating  categories  of the
recognized rating services.
 
MONEY MANAGER COMMENTARY:
 
The Series  returned  1.32% since its  inception,  versus  0.63% for the Salomon
Smith Barney High Yield Market Index.
 
The U.S. high yield bond market experienced a volatile year in 1998, compared to
recent  years.  Weakened  global  economies  and  financial  markets  negatively
affected the high yield market for both fundamental reasons as well as technical
market  reasons.  The market  started out  respectably  but  experienced a sharp
downward  correction  of 6.8% (as  reported by Salomon  Smith  Barney High Yield
Index) in August as global assets,  triggered by Russia's debt crisis,  affected
all markets globally.
 
The first seven months of the year in the high yield market  returned  5.99% and
were characterized by relative calm in both underlying credit quality and market
conditions.  Market default statistics were consistent with 1997 at historically
low levels,  characterizing  reasonable  credit quality for broad sectors of the
market.  Simultaneously,  the market was starting to  experience  a  significant
weakening in operating results and credit quality from companies most vulnerable
to the global economic slowdown emanating from the Asian economic crisis. Driven
by global  overcapacity  and slackened  demand,  commodity prices worldwide were
tumbling,  severely affecting  companies in the energy and oil services sectors,
paper and forest products, steel and other metals and chemicals.
 
The first part of the year was also driven by strong technical market conditions
in high yield. A large  financing  calendar -- 691 new issues for the year for a
total of $138.9 billion -- was  comfortably  absorbed by the mutual fund inflows
asset  allocations  to high  yield by  institutional  investors  and  structured
finance  investments.  Credit spreads,  or the yield premium above U.S. treasury
bonds which the high yield market pays,  gradually  widened as treasury  markets
rallied.
 
In August,  extreme volatility hit the world's financial markets,  including the
U.S.  high  yield  bond  market.  Precipitated  by the  inability  of  Russia to
refinance its local treasury  bills, a global "flight to quality"  ensued,  with
investors in a panic  exiting  riskier  asset  classes and buying U.S.  treasury
bonds. The U.S. equity market,  U.S. high yield, U.S. investment grade corporate
and mortgage bonds, and most notably emerging market bonds,  declined materially
in price.  This  "flight to  quality"  was  magnified  by forced  selling out on
leveraged  investment  vehicles,  commonly known as "hedge funds",  which had to
sell these investments to meet margin calls on borrowings.
 
By October,  things had calmed down  somewhat,  and the U.S.  high yield  market
returned 3.50% for the fourth quarter as sell pressure abated and credit spreads
declined.  After two very slow,  almost  dormant  months for  financing,  better
quality  companies were able to re-enter the market for financing,  although the
previously restored commodity cyclical companies still faced difficulty.

                                    QUALITY BOND SERIES
                                  SALOMON BROTHERS ASSET MANAGEMENT INC
                                  ROGER LAVAN
 
OBJECTIVE:
 
Salomon  Brothers/JNL  U.S.  Government  &  Quality  Bond  Series  seeks  as its
investment  objective a high level of current income, by investing  primarily in
debt obligations and mortgage-backed securities issued or guaranteed by the U.S.
Government, its agencies or instrumentalities  including collateralized mortgage
obligations  backed by such securities.  The Series may also invest a portion of
its assets in investment-grade bonds.
 
MONEY MANAGER COMMENTARY:
 
The Series returned 9.40% for 1998, placing it 1st out of 33 funds in its Lipper
category. The Series outperformance resulted from its shift into longer duration
bonds and a sizable allocation to Treasuries.
 
In January,  we believed  Asia's economic woes would slow economic growth in the
U.S. and push inflation  lower.  This would enable interest rates, in particular
long-term  rates,  to move modestly lower,  pushing bond prices higher.  To take
advantage  of our  expectations  for lower  interest  rates and a flatter  yield
curve,  we moved the Series into a slightly  long  duration  barbelled  position
while overweighting discount mortgage securities.
 
We held this position until  mid-August  when it became apparent that the global
economy  would slow down more than thought  previously  and the Federal  Reserve
would ease  monetary  policy.  We  strategically  reduced  the  Series'  barbell
position  by  swapping  long  maturity  Treasuries  and  mortgages  into  5-year
Treasuries. The 5-year area of the Treasury curve often performs best just prior
to a Federal easing cycle and this time was no exception.  To maintain duration,
we sold mortgage securities trading above par and bought discount pass-throughs.
 
During the fourth  quarter,  it became  apparent  to  investors  that the global
market crisis that began in mid-1997 had stabilized. A 75 basis point cut of the
Federal  funds rate by the Federal  Reserve  restored  investor  confidence  and
liquidity  in  the  markets.  The  main  strategy  change  in the  Series  was a
reallocation to mortgage pass-throughs from Treasuries.
 
After seven years of  uninterrupted  growth,  the U.S. economy faces a period of
slowing  expansion and  threatened  instability.  Although key areas of economic
activity remain buoyant, gradual slowing remains a likely scenario for 1999. The
Federal   Reserve   will   probably   condition   further   easing  on   renewed
intensification  of  financial  stress of  evidence  that demand  pressures  are
receding.
 
We expect  interest rates to generally move lower in the first few months of the
year,  followed by a gradual rise through the end of 1999.  With the expectation
of further Federal Reserve  easing,  we look for the yield curve to steepen.  As
such,  long-term  bonds may  stabilize  in a range  centered on 5% as  long-term
inflation expectations fall.

                                  T. ROWE PRICE ASSOCIATES, INC.
[T. ROWE PRICE LOGO]              ROBERT W. SMITH
 
OBJECTIVE:
 
T. Rowe Price/JNL  Established  Growth Series seeks as its investment  objective
long-term  growth of capital and increasing  dividend income through  investment
primarily in common stocks of well-established growth companies.
 
MONEY MANAGER COMMENTARY:
 
The Series  return of 27.78%  outperformed  the Lipper VA Growth Fund  Average's
return of 24.94%,  but slightly trailed the S&P 500 Index's return of 28.58% for
the year ended December 31, 1998. The narrowness of the S&P 500 Index  continued
as most of the performance came from the top 50 blue chip stocks.  This was also
true for the Series as the smaller companies in the portfolio  continued to lag.
International holdings also continued to underperform slightly.
 
Over the last six months many  negative  developments  attempted to stand in the
way of the bull  market and the robust U.S.  economy.  Russia  defaulted  on its
loans,  causing panic in emerging  markets and a looming credit crunch both here
and abroad.  Before much damage  could be  inflicted  on the U.S.  economy,  the
Federal Reserve Bank stepped in by lowering rates in the U.S. several times, and
the IMF put a package  together  to  stabilize  Latin  America.  This calmed the
market and restored consumer  confidence.  While the manufacturing sector slowed
noticeably,  other  elements of the economy  remained  relatively  strong.  This
calming effort, combined with the public's insatiable appetite for stocks, drove
the market up sharply at year-end, surpassing highs reached in July.
 
Several  of our  large  holdings  did  quite  well.  America  Online,  which was
purchased early in the year,  performed  exceedingly well.  Network  Associates,
EMC, Microsoft,  MCI WorldCom,  and Intel also added nicely to returns. In other
sectors,  the  Series  was helped by our large  positions  in Federal  Home Loan
Mortgage  Corp.,  Safeway,  Home  Depot,  Philip  Morris,  and  Danaher.  On the
international  side,  ACE Ltd.,  Wolters  Kluwer,  and  Hutchison  Whampoa  were
positive contributors.
 
Many of our financial stocks detracted from performance.  Trading activities and
poor foreign  loans  affected  Citigroup,  and general  soft markets  negatively
affected our insurance holdings. As usual, a few earnings disappointments,  like
Parametric  Technology and United  HealthCare,  also impacted  returns.  In most
cases we held or added to these positions.
 
The U.S.  stock market has continued to advance  despite many efforts to slow it
down. The Federal Reserve Bank continues to masterfully steer the economic ship,
and U.S. companies continue to be world leaders and shareholder  focused. On the
negative  side,  valuations  are extreme,  industrial  America is troubled,  and
consumers  continue to spend and not save.  In  addition,  economies  around the
world  appear to remain  volatile.  While the market was  rewarded  with  strong
returns in 1998, earnings and cash flow at companies showed little growth.
 
Over time,  stocks  cannot  continue  to move  upward at a faster  rate than the
underlying  cash flow.  This could  produce  lower stock  market  returns in the
period ahead.  We do,  however,  feel  confident that the companies that make up
your  portfolio  will  continue  to grow to their "true  value"  faster than the
overall market.

                                  ROWE PRICE-FLEMING INTERNATIONAL, INC.
[T. ROWE PRICE LOGO]              ADVISORY COMMITTEE
 
OBJECTIVE:
 
T. Rowe Price/JNL International Equity Investment Series seeks as its investment
objective  long-term growth of capital through  investments  primarily in common
stocks of established, non-U.S. companies.
 
MONEY MANAGER COMMENTARY:
 
For the  year,  the MSCI  E.A.FE.  benchmark  was up  20.33%,  helped  by dollar
weakness that contributed  about one-third of the gain.  Europe, up 29%, was the
strongest  international region in 1998, while Latin America,  down 35%, was the
weakest.  Latin America suffered the savage sell-off that afflicted the Far East
last  year  as  "Asian  contagion",  exacerbated  by  the  Russian  default  and
devaluation,  induced a loss of  confidence  in  Brazil  and the  region.  Japan
managed a modest  increase of 5% in U.S.  dollar terms,  but the rest of the Far
East, excluding Australia, declined 5%. In 1998, the dollar fell 13% against the
yen, 7% against major European currencies, and 1% against pound sterling.
 
For 1998, the 14.43% return of the Series underperformed the MSCI E.A.FE. Index.
Country allocation relative to the benchmark was negative over the year. For the
year,  underweighting  Japan, in particular,  and Asia to a lesser extent, added
value.  However,  these  gains  were  offset  largely by our  position  in Latin
America, with smaller negatives from overweighting Norway and underweighting the
buoyant Finnish and German markets.  For the year, stock selection was positive,
with  holdings  in the  Netherlands,  Belgium,  France,  and Japan  particularly
successful.
 
During the fourth quarter,  we selectively  reduced holdings in Europe,  such as
French  retailer  Pinault  Printemps,   which  performed  strongly  and  may  be
vulnerable to weaker demand.  Deutsche Telekom was reduced;  we bought new issue
Swisscom  and added to Spanish  Telefonica,  which offer better value and growth
prospects.  The  European  savings  market is  expanding  rapidly so we added to
insurers  including  Italian company INA. In Japan we bought mobile telecoms new
issue,  DoCoMo,  spun off by its parent NTT.  In Hong Kong we reduced  Hong Kong
Telecom and added China Telecom  which  operates in a less  competitive,  higher
growth environment.
 
At the end of 1998, the Series was slightly underweighted in the UK and slightly
overweighted in Continental  Europe.  Japan and the Pacific region also remained
underweighted.
 
Looking  forward,  we see  international  economies  growing  more  slowly.  Our
cautious  stance in the  Pacific  and Japan will help shield the Series from the
pain that those markets must go through before they can emerge as  fundamentally
healthy investment  centers.  The Series emphasis on businesses,  which have the
management,  products,  and sound finances to support sustainable growth, should
prove appropriate as cyclical business face a tougher environment.
 
Corporate  activity  and  restructuring  in Europe are  expected  to continue as
Economic and Monetary Union (EMU),  deregulation,  and a weaker economy coincide
in the year  ahead.  The extent of  corporate  consolidation  in Europe lags the
U.S., and thus there is further scope for industry concentration. Our enthusiasm
for  Continental  Europe  remains high, as we continue to find  businesses  with
sustainable  growth  prospects,  managed  to  maximize  returns,  at  reasonable
valuations.
 
The  Japanese  government's  long  overdue  action  in  the  fourth  quarter  is
encouraging.  We remain underweighted,  though, because at the stock level there
are relatively few companies focused on shareholder  value,  willing to take the
tough  actions  that  may be  required  in  the  recessionary  and  deflationary
environment of Japan at present.
 
In the rest of the Far East,  the bottom of the  crisis  may be at hand,  but we
believe that valuations bear little relationship to the underlying merits of the
stocks.  We  retain  our  belief  that  Latin  America  offers  attractions  and
opportunity.  The key remains avoiding a disorderly  devaluation in Brazil.  Our
view is that this is possible, and the Series holdings will, in time, be able to
achieve valuations closer to those of international sector peers.
 
Our outlook for currencies  favors the new euro currency over the dollar and the
yen, although we do not anticipate major moves in the year ahead.
 
Confidence  has clearly  returned to global stock  markets  after the  difficult
third quarter.  Looking ahead, we believe that this renewed confidence,  coupled
with healthy if unspectacular economic growth in Europe and signs that we are at
least  closer to the  bottom in Asia will lead to  reasonable  performance  from
international equity markets in 1999.

[T. ROWE PRICE LOGO]              INVESTMENT ADVISORY COMMITTEE

OBJECTIVE:
 
T. Rowe  Price/JNL  Mid-Cap  Growth  Series  seeks as its  investment  objective
long-term  growth of  capital by  investing  primarily  in the  common  stock of
companies with medium-sized market capitalizations ("mid-cap") and the potential
for above average growth.
 
MONEY MANAGER COMMENTARY:
 
Despite increased market  volatility  during the year,  investors enjoyed strong
gains again in 1998 as the S&P 500 soared 28.58%, its fourth consecutive year of
returns in excess of 20%.  Although  mid-cap stocks still lagged their large-cap
peers,  the S&P Mid-Cap 400 Index rebounded after a decline of 30% from its high
in April to finish  the year with a 19.11%  gain.  In June,  we warned  that the
historically  high  valuations of U.S.  stocks could increase the volatility and
risk  in  the  market.  Indeed,  increasing  instability  in  emerging  markets,
political  turmoil in major markets such as the U.S.,  Japan,  and Germany,  and
indications  of ebbing U.S.  economic  growth  generated  sharp  declines in all
sectors of the market and contributed to a brief credit crunch.  However,  three
interest rate cuts by the Federal  Reserve  within a two-month  period this fall
seem to have allayed investor fears, and revived the aging bull market.
 
The Series outperformed two passive benchmarks, the S&P MidCap 400 Index and the
Russell Midcap Growth Index, for the year, though it lagged slightly in the last
quarter.  The Series easily beat the Lipper Mid Cap Fund Index for both periods.
Throughout the year, the Internet sector waylaid many  institutional  investors,
including us. America  Online,  for example,  began 1998 as a $10 billion market
capitalization  company,  double the upper  threshold  of what we consider to be
mid-cap  but  still in the S&P  Mid-Cap  400  Index.  As the stock  rose  almost
sevenfold during the year, it contributed approximately 7% of the index's 19.11%
gain for 1998, vastly exceeding the contribution of any other stock,  ever, to a
major U.S. stock index.
 
Following the trend of recent quarters,  some of our best performers were in the
health care and technology  sectors.  Top  contributors for the quarter included
Gilead  Sciences,  a leading  developer of antiviral  products,  whose new drugs
treating influenza and HIV are showing promising results;  and Analog Devices, a
leading  supplier of  integrated  chips,  whose stock rose strongly as investors
perceived that industry  fundamentals were improving.  The top performer for the
year was Biogen,  which  continues  to  experience  strong sales of its multiple
sclerosis treatment drug, Avonex.
 
The  most  deleterious  contributor  to the  Series'  performance  for  1998 was
Security Capital Group, a commercial real estate  investment  advisory  company;
commercial  property  stocks were pummeled this year,  and the company fell well
short of investors' earnings expectations.
 
During the fourth quarter, we added to our weighting in the consumer sector, and
also  modestly  increased  our  holdings  in  technology,  where  we  have  been
underweighted.
 
With the strong  fourth  quarter  rebound,  the stock market has returned to the
upper reaches of its historic  valuation  range,  but low interest rates provide
some support if earnings growth continues.  It remains to be seen,  however,  if
pressures from the global  economic  crisis begun in Thailand in 1997 have truly
abated.  Meanwhile,  the market's leadership remains with an increasingly narrow
group of large,  blue chip  companies.  While these  companies  have grown their
earnings  nicely in recent years,  they now trade at valuations that are well in
excess of small-  and  mid-cap  companies,  even  though  many of the latter are
expected to grow their earnings  significantly faster in the next few years with
less  international  risk. On a relative  basis,  small- and mid-cap  stocks are
trading at historically low levels.  We believe the Series is well positioned to
achieve  attractive  returns over the long run and should  benefit  particularly
when the mid-cap sector returns to favor among investors.

- --------------------------------------------------------------------------------

NOTE 2.  SIGNIFICANT ACCOUNTING POLICIES

     The following is a summary of significant  accounting  policies followed by
the Trust in the preparation of its financial statements.

     Use of Estimates -- The  preparation of financial  statements in conformity
with  generally  accepted  accounting  principles  requires  management  to make
estimates and assumptions. Actual results could differ from those estimates.

     Security  Valuation -- Bonds are valued on the basis of prices furnished by
pricing  services which determine prices for normal  institutional  size trading
units  of  bonds  or  based  on  quotations  provided  by  broker-dealers.  When
quotations  are not readily  available,  bonds are valued at fair  market  value
determined by procedures  approved by the Board of Trustees.  Stocks listed on a
national or foreign stock exchange are valued at the final sale price,  or final
bid price in absence of a sale. Stocks not listed on a national or foreign stock
exchange  are valued at the  closing bid price on the  over-the-counter  market.
Short-term securities maturing within 60 days of purchase, and all securities in
the PPM America/JNL  Money Market Series,  are valued at amortized  cost,  which
approximates  market value.  American  Depository  Receipts ("ADRs"),  which are
certificates representing shares of foreign securities deposited in domestic and
foreign banks, are traded and valued in U.S. dollars.

                                JNL SERIES TRUST
                  NOTES TO THE FINANCIAL STATEMENTS (continued)
- --------------------------------------------------------------------------------

      JNL/S&P   Conservative  Growth  I,  JNL/S&P  Moderate  Growth  I,  JNL/S&P
Aggressive  Growth I, JNL/S&P Very Aggressive Growth I, JNL/S&P Equity Growth I,
JNL/S&P  Equity  Aggressive  Growth I, JNL/S&P  Conservative  Growth II, JNL/S&P
Moderate Growth II, JNL/S&P Aggressive Growth II, JNL/S&P Very Aggressive Growth
II, JNL/S&P Equity Growth II and JNL/S&P Equity  Aggressive Growth II are valued
at the net asset value per share of each  Underlying  Fund  determined as of the
close of the New York Stock Exchange on the valuation date.

     Security  Transactions and Investment  Income -- Security  transactions are
recorded on the trade date. Dividend income is recorded on the ex-dividend date.
Interest income,  including level-yield  amortization of discounts and premiums,
is accrued  daily.  Realized  gains and losses are  determined  on the  specific
identification basis.

     Foreign  Currency  Translations -- The accounting  records of the Trust are
maintained  in  U.S.  dollars.   Investment  securities  and  other  assets  and
liabilities  de-nominated in a foreign currency are translated into U.S. dollars
using  exchange  rates in effect at the  close of the New York  Stock  Exchange.
Purchases  and sales of  investment  securities,  income  receipts,  and expense
payments are translated  into U.S.  dollars at the exchange rates  prevailing on
the respective dates of such transactions.

     Realized  gains and losses  arising from  selling  foreign  currencies  and
certain non-dollar  denominated fixed income  securities,  entering into forward
foreign currency exchange  contracts,  and accruing income or settling portfolio
purchases  and sales  denominated  in a foreign  currency  paid or received at a
later date are recorded as net realized  foreign currency related gains (losses)
and are  considered  ordinary  income for tax purposes.  Realized and unrealized
gains and losses on  investments  which result from changes in foreign  currency
exchange  rates  are  primarily  included  in net  realized  gains  (losses)  on
investments  and net  unrealized  appreciation  (depreciation)  on  investments,
respectively.

     Forward  Foreign  Currency  Exchange  Contracts  -- A Series may enter into
forward foreign currency exchange  contracts  ("contracts"),  generally to hedge
foreign  currency  exposure  between trade date and settlement  date on security
purchases  and sales ("spot  hedges") or to minimize  foreign  currency  risk on
portfolio securities  denominated in foreign currencies ("position hedges"). All
contracts   are  valued  at  the  for-ward   currency   exchange  rate  and  are
marked-to-market daily. When the contract is open, the change in market value is
recorded  as net  unrealized  appreciation  (depreciation)  on foreign  currency
related items. When the contract is closed,  the difference between the value of
the  contract  at the time it was opened and the value at the time it was closed
is recorded as net realized gain (loss) on foreign currency related items.

     The use of forward foreign currency  exchange  contracts does not eliminate
fluctuations in the underlying prices of the Series' portfolio  securities,  but
it does  establish a rate of exchange that can be achieved in the future.  These
forward  foreign  currency  contracts  involve  market  risk  in  excess  of the
unrealized  appreciation  (depreciation)  of forward foreign currency  contracts
reflected in the Statement of Assets and Liabilities.  Although  contracts limit
the risk of loss due to a decline in the value of the hedged currency, they also
limit any  potential  gain that might  result  should the value of the  currency
increase.  Additionally, the Series could be exposed to the risk of a previously
hedged position  becoming  unhedged if the  counterparties  to the contracts are
unable to meet the terms of the contracts.  See Note 7 for a listing of position
hedges as of December 31, 1998.

     When-Issued  and Delayed  Delivery  Transactions  -- A Series may  purchase
securities on a when-issued or delayed  delivery  basis.  On the trade date, the
Series record  purchases of  when-issued  securities  and reflects the values of
such  securities  in  determining  net asset  value in the same  manner as other
portfolio securities. Income is not accrued until settlement date.

     Unregistered  Securities -- A Series may own certain investment  securities
which are  unregistered  and thus  restricted to resale.  These  securities  are
valued by the  Series  after  giving  due  consideration  to  pertinent  factors
including  recent private sales,  market  conditions and the issuer's  financial
performance.  Where future  dispositions of the securities require  registration
under the  Securities  Act of 1933,  the Series have the right to include  their
securities in such registration generally without cost to the Series. The Series
have no right to  require  registration  of  unregistered  securities.  Illiquid
securities are limited to 15% (10% in the case of PPM  America/JNL  Money Market
Series and the JNL/Alger Growth Series) of the net assets of a Series.

                  NOTES TO THE FINANCIAL STATEMENTS (continued)
- --------------------------------------------------------------------------------

     Options  Transactions  -- A  Series  may  write  covered  call  options  on
portfolio securities.  Written options involve, to varying degrees, risk of loss
in  excess  of the  option  value  reflected  in the  Statement  of  Assets  and
Liabilities.  The risk in writing a covered  call  option is that the Series may
forego the opportunity of profit if the market price of the underlying  security
increases  and the  option is  exercised.  Option  contracts  are  valued at the
closing  prices on their  exchanges  and the Series will  realize a gain or loss
upon  expiration  or  closing  of the  option  transaction.  When an  option  is
exercised,  the  proceeds on sales for a written call option are adjusted by the
amount of premium received.

     Futures  Contracts -- A Series may utilize  futures  contracts to a limited
extent.  The risks  associated  with the use of futures  contracts  include  the
possibility that the value may not correlate with the change in the value of the
hedged  instruments.  In addition,  there is the risk that the Series may not be
able to enter into a closing  transaction  because of an illiquid market. . Upon
entering  into a futures  contract,  the Series is required to deposit  with the
broker an amount of cash or cash  equivalents  equal to a certain  percentage of
the contract amount.  This is known as the "initial  margin".  Futures contracts
are valued based upon their quoted daily settlement  prices.  The Series receive
from or pay to brokers an amount of cash equal to the daily  fluctuation  in the
value of the  contracts.  Such  receipts or  payments,  known as the  "variation
margin," are recorded by the Series as  unrealized  appreciation  (depreciation)
until the contracts are  terminated at which time realized  gains and losses are
recognized.  Futures  contracts  involve,  to varying  degrees,  risk of loss in
excess of the futures variation margin reflected in the Statements of Assets and
Liabilities.

     Short Positions -- A Series may sell securities short for hedging purposes.
For financial  statement  purposes,  an amount equal to the settlement amount is
included in the Statement of Assets and  Liabilities  as an asset and equivalent
liability.  The amount of the  liability  is  subsequently  marked-to-market  to
reflect the current  value of the short  position.  The Series is liable for any
dividends  payable on securities while those securities are in a short position.
As collateral for its short positions, the Series is required under the 1940 Act
to maintain  segregated  assets  consisting of cash, cash  equivalents or liquid
securities. These segregated assets are required to be adjusted daily to reflect
changes in the value of the securities sold short.

     Dollar Roll Transactions -- The Salomon  Broth-ers/JNL  Global Bond Series,
Salomon  Brothers/JNL  U.S.  Government  &  Quality  Bond  Series,  and  Salomon
Brothers/JNL  Balanced  Series  may enter into  dollar  roll  transactions  with
respect to mortgage securities in which the Series sells mortgage securities and
simultaneously  agrees to repurchase  similar  (same type,  coupon and maturity)
securities at a later date at an agreed upon price. The value of the dollar roll
transactions are reflected in the Series'  Statements of Assets and Liabilities.
During the period between the sale and repurchase,  the Series forgoes principal
and interest paid on the mortgage  securities sold. The Series is compensated by
the interest earned on the cash proceeds of the initial sale and from negotiated
fees paid by brokers  offered as an  inducement to the Series to "roll over" its
purchase  commitments.  These fees are  accrued  as income  over the life of the
dollar roll contract.  Dollar roll transactions involve the risk that the market
value of the  securities  sold by the Series may  decline  below the  repurchase
price of those similar  securities  which the Series is obligated to purchase or
that the return  earned by the Series with the proceeds of a dollar roll may not
exceed transaction costs.

     Repurchase  Agreements -- A Series may invest in repurchase  agreements.  A
repurchase  agreement  involves  the  purchase  of a security  by a Series and a
simultaneous agreement (generally by a bank or broker-dealer) to repurchase that
security  back from the  Series at a  specified  price and date or upon  demand.
Securities  pledged as  collateral  for  repurchase  agreements  are held by the
Series custodian bank until the maturity of the repurchase agreement. Procedures
for all repurchase agreements have been designed to assure that the daily market
value of the collateral is in excess of the repurchase agreement in the event of
default.

                  NOTES TO THE FINANCIAL STATEMENTS (continued)
- --------------------------------------------------------------------------------

     Reverse Repurchase  Agreements -- A Series may engage in reverse repurchase
agreements  to borrow  short term  funds.  The value of the  reverse  repurchase
agreements that the Series have committed to sell are reflected in the Statement
of Assets and  Liabilities.  The Series will  maintain  securities in segregated
accounts  with its  custodian  that at all times are in an amount equal to their
obligations  under  the  reverse  repurchase   agreements.   Reverse  repurchase
agreements involve the risks that the market value of the securities sold by the
Series may decline  below the  repurchase  price and, if the  proceeds  from the
reverse repurchase  agreement are invested in securities,  that the market value
of  the  securities  bought  may  decline  below  the  repurchase  price  of the
securities sold.

     Securities  Loaned -- The  Series has  entered  into a  securities  lending
arrangement  with the custodian.  Under the terms of the  agreement,  the Series
receives 65% of the annual net income from lending transactions. In exchange for
such fees,  the  custodian is  authorized  to loan  securities  on behalf of the
Series,  against  receipt of  collateral at least equal in value to the value of
the  securities  loaned.  Cash  collateral is invested by the custodian in money
market  instruments  approved by the  Manager.  The Series bears the risk of any
deficiency in the amount of collateral available for return to a borrower due to
a loss in an approved investment.

     Distributions To Shareholders -- The PPM  Amer-ica/JNL  Money Market Series
declares  dividends  daily and pays  dividends  monthly.  For all other  Series,
div-idends from net investment income are declared and paid annually, but may be
done more frequently to avoid excise tax.  Distributions of net realized capital
gains, if any, will be distributed at least annually.

     Federal  Income  Taxes  --  The  Trust's  policy  is  to  comply  with  the
requirements  of the Internal  Revenue Code  applicable to regulated  investment
companies and to distribute  income in amounts that will avoid federal income or
excise taxes for each Series.  The Trust  periodically  makes  reclassifications
among  certain  of its  capital  accounts  as a result  of the  recognition  and
char-acterization  of certain income and capital gain dist-ributions  determined
annually  in  accordance  with  federal  tax  regulations  which may differ from
generally accepted accounting principles.

NOTE 3.  INVESTMENT MANAGEMENT FEES AND TRANSACTIONS WITH AFFILIATES

     The Trust has an  investment  advisory  agreement  with JNFS  whereby  JNFS
provides  investment  management and transfer agency services.  Each Series pays
JNFS a fee, computed daily and payable monthly,  based on a specified percentage
of the average  daily net assets of each Series.  The following is a schedule of
the fees each Series is currently obligated to pay JNFS.

NOTE 6.  FOREIGN SECURITIES

     Investing  in  securities  of foreign  companies  and  foreign  governments
involves  special  risks  and  considerations  not  typically   associated  with
investing  in U.S.  companies  and the  U.S.  Government.  These  risks  include
revaluation   of   currencies   and  future   adverse   political  and  economic
developments.  Moreover,  securities  of  many  foreign  companies  and  foreign
governments  and their markets may be less liquid and their prices more volatile
than those of securities of comparable U.S. companies and the U.S. Government.

                        REPORT OF INDEPENDENT ACCOUNTANTS

- --------------------------------------------------------------------------------



To the Shareholders and Board of Trustees of JNL Series Trust

         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 each of the  thirty-six  Series
comprising  the JNL Series  Trust  (hereafter  referred  to as the  "Trust")  at
December 31, 1998, and the results of each of their operations,  changes in each
of their net assets and the financial  highlights for the periods indicated from
inception to December 31, 1998, in conformity with generally accepted accounting
principles.  These  financial  statements  and financial  highlights  (hereafter
referred to as "financial  statements")  are the  responsibility  of the Trust's
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 December 31, 1998,  by  correspondence  with the
custodian  and  brokers,  provide a reasonable  basis for the opinion  expressed
above.
