                                                               February 5, 1999

Dear Contract Owner:

   J. & W. Seligman & Co. Incorporated, as Manager of Seligman Portfolios, Inc.
(the "Fund"), is pleased to provide the enclosed audited financial statements
and accompanying information for the year ended December 31, 1998.

   In 1998, for the eighth  straight year,  the US economy  expanded,  with real
domestic  growth of 3.9%.  Once again,  large-cap  US stocks  responded  to this
favorable  environment with strong  performance.  The market, as measured by the
Standard & Poor's 500 Composite  Stock Price Index (S&P 500), rose 28.58% -- the
first time in history that this widely watched index returned more than 20% for
four years in a row.

   Although  1998  will  certainly  be  recorded  as  another  stellar  year for
equities,  the market gave  investors a bumpy ride along the way. In fact,  such
wide market swings haven't been seen since 1987. A number of factors contributed
to this  volatility -- some domestic,  many  international.  The global economic
background in 1998 was one of steadily deteriorating conditions as the financial
crisis,  originally  limited to a few Asian countries,  spread  throughout other
regions.  The global  turmoil  continued  when Russia  defaulted on its debt and
devalued its  currency,  and investors  everywhere  feared that Brazil and other
Latin American countries would follow.

   In addition  to high  volatility,  last  year's  market was notable for being
extremely narrow,  with the exceptional  performances of a few stocks distorting
the  total  picture.  In  fact,  197  stocks,  representing  39% of the S&P 500,
actually lost market value during the last 12 months. Investment results between
market caps were also more widely dispersed than usual. The disparity was almost
unprecedented.  For  example,  the  large-capitalization-dominated  S&P 500 rose
28.58%, while the Russell 2000 Index of  smaller-capitalization  stocks actually
declined 2.55%.

   International  markets  began the year with  generally  strong  performances,
fueled by expectations of lower inflation and falling interest rates.  Beginning
in mid-July,  however, the combination of the Russian debt default,  speculative
attacks against emerging market currencies,  and a worse-than-expected  economic
impact from Asia on the rest of the world led to sharp market corrections. Then,
in October,  markets  recovered as interest  rates were cut in many parts of the
world and a coordinated  program of support for the world's financial system was
implemented.

   Fixed-income markets posted strong returns for the year but, as in the equity
markets,  some segments performed notably better than others. US Treasury bonds,
in particular,  benefitted  from a confluence of events that drove prices higher
and yields to 30-year lows. US government-backed  bonds, which carry the highest
credit quality,  were in great demand as the global financial turmoil produced a
"flight to quality"  around the world.  Further  boosting the US government bond
market was the Federal Reserve Board's lowering of the federal-funds rate, and a
federal budget surplus which caused the overall supply of bonds to decrease.

   In 1999,  we believe  gross  domestic  product (GDP) should slow to about 2.5
percent.  We expect a  challenging  financial  market  environment  with ongoing
economic  uncertainties  and  continued  high  volatility.  Nonetheless,  we see
moderately  positive  returns  for the  year  in  line  with  our  lower  growth
projections.  In addition,  low  inflation,  falling or stable  interest  rates,
improving  prospects in Asia,  and a Federal  Reserve  leading the fight against
global recession  should all provide support for US markets.  We expect that the
equity market,  which began to show signs of broadening in the fourth quarter of
1998,  will  continue to broaden in 1999.  If this trend  continues,  small- and
mid-cap stocks should begin to benefit from the favorable equity  environment to
a greater extent.

   Thank you for your  continued  support of Seligman  Portfolios,  Inc. We look
forward to continuing to serve your investment needs in 1999.

                                            Respectfully,

                                            /S/ William C. Morris

   Global financial turmoil  throughout 1998 had investors  throughout the world
pursuing the perceived  safety of the highest  credit  quality  securities -- US
Treasury  bonds.  At the same  time,  the  Federal  Reserve  Board  lowered  the
federal-funds  rate while a federal  budget surplus caused the overall supply of
bonds to decrease, as the government needed less paper to finance spending. This
combination  of factors  drove US  Treasury  yields to 30-year  lows,  which was
positive for the Portfolio.  The long bond began the year with a yield of 5.92%,
and fell to a low of 4.70% before moving back up to close the year at 5.09%.

   During  the year,  as the spread  between  Treasuries  and agency  securities
widened, we increased the Portfolio's  exposure to agencies to pursue additional
yield.  As the year  progressed,  we reduced  our  exposure  to  mortgage-backed
securities,  selling higher-coupon  securities as concerns over prepayments in a
falling-interest-rate   environment  made  other  areas  more  attractive.  This
strategy was successful; however, even our reduced exposure placed a slight drag
on performance  in the third quarter as the flight to Treasuries  hurt all other
types of bonds.

   Going  forward,  we may  shorten the  Portfolio's  duration as the rewards of
maintaining a longer duration become less compelling.  The Portfolio's  duration
is  currently  about  6.4  years,  which is  slightly  longer  than  that of our
benchmark,  the Lehman  Brothers  Government  Bond  Index.  In the coming  year,
ongoing  global  problems  and the  continuing  disappearance  of the US  budget
deficit should  combine to keep supply low and demand high, a positive  scenario
for the  Portfolio.  In  addition,  we will  continue to seek  opportunities  in
non-Treasury securities to enhance the Portfolio's yield and total return.

   Last year's economic  environment of subdued  inflation,  low interest rates,
and strong consumer demand pro vided a favorable backdrop for mid-capitalization
(between $1 billion and $10 billion in market  value)  growth  stocks.  However,
ongoing  concerns  regarding  global  financial  problems  produced a "flight to
quality"  that favored  larger-cap  stocks.  This bias hurt the  performance  of
small- and mid-cap stocks,  despite their attractive  fundamentals.  However, in
the  fourth  quarter,  the market  began to broaden to include a wider  range of
market caps -- a favorable development for the Portfolio.

SELIGMAN CAPITAL PORTFOLIO (continued)

   Technology,  telecommunication, and consumer-cyclical companies had a year of
strong  earnings,  which  translated  into solid returns for the  Portfolio.  In
technology, anything Internet-related performed extremely well. While we did not
own any pure-play Internet companies -- due to their astronomical valuations and
lack of earnings -- we  nonetheless  benefited from the Internet boom as many of
our  technology   holdings  are  involved  in  building  and   maintaining   the
infrastructure of the Internet.

   The Portfolio's  exposure to industrial  companies hurt overall  performance.
Global  deflation  in  commodity  prices,  along  with  fallout  from the  Asian
Financial  crisis,  negatively  impacted  this  sector.  Although  none  of  our
industrial holdings had direct exposure to Asia, many of their customers did and
thus were hurt indirectly.

   Going into 1999, conditions appear positive for the Portfolio. Valuations for
many  quality  mid-cap  stocks  are  attractive,   especially  relative  to  the
larger-cap  stocks whose prices were driven up during last year's  narrow market
run-up.  If the market  continues  to broaden -- a trend that we began to see in
the fourth  quarter of 1998 -- the mid-cap  stocks held by the  Portfolio  would
benefit. In addition, we believe that, like last year, companies that can either
meet or surpass earnings  estimates will be rewarded,  while companies that fall
short will be punished  severely.  This is another  positive for the  Portfolio,
which looks for companies with the potential for positive earnings surprises. As
1999  begins,  we  believe  that the  areas  of  broadcasting  and  advertising,
telecommunications,  and  specialty  retailers  have  good  prospects  for  such
earnings  surprises.  Finally, we see the biggest risks to the US market in 1999
coming from abroad.  The Portfolio,  however,  should be largely  insulated from
this  because the mid-cap  companies  in the  Portfolio  are domestic in nature,
relying little on international markets for earnings growth.

   In 1998,  the US  economy  expanded  for the  eighth  consecutive  year.  Low
inflation,  continued  corporate  earnings  growth,  and a benign  interest rate
environment combined to propel US stocks higher -- especially the largest,  most
liquid names,  as investors tried to insulate  themselves from global  financial
turmoil. The Portfolio,  which generally invests in large-cap stocks,  benefited
from this year-long trend.

   The  Portfolio   remains  broadly   diversified  among  industry  groups  and
individual holdings; however, we have reduced our number of holdings to focus on
companies  with  stable  earnings  and  dividend  growth,  which are  selling at
reasonable  valuations relative to their industries.  This approach was positive
for the  Portfolio  during  last  summer's  market  downturn  since it led us to
underweight many excessively valued large-capitalization  stocks, which were hit
the hardest during that difficult environment.

   During the year, we increased our exposure to technology, and by year-end the
industry  represented  15% of the  Portfolio.  The group  rallied  in the fourth
quarter,   allowing  these   holdings  to  contribute   positively  to  absolute
performance;  however,  relative to the S&P 500 we lost some  ground,  since our
weighting was slightly less than the 17% weighting of the Index.  In addition to
our technology holdings, the Portfolio benefited from our telecommunications and
health care holdings.

   The  weakest  area of the  Portfolio  were  cyclical  stocks.  While  we were
generally  underweight in these issues, they did negatively impact results.  Our
energy stocks also adversely  affected our returns.  Weak demand from Asia, warm
weather in the US, and an overall free-fall in commodity prices around the world
all  contributed to the poor showing of energy stocks in 1998. And while many of
our energy  holdings  did better  than the  sector as a whole,  they  lagged the
overall market in 1998.

   We believe that the  fundamentals  of the US economy  remain  strong and will
provide a  supportive  environment  for  equities  in 1999.  However,  we remain
cautious of the high valuations on many of the largest stocks and fear that much
of this has been driven by liquidity factors,  not fundamentals.  Therefore,  we
will look for companies with attractive valuations that more fully reflect their
future  prospects,  and  where we  believe  there  is a  catalyst  for  earnings
acceleration going forward.

   As  was  the  case  in  the  broader  market,   large-cap  technology  stocks
outperformed  their small- and mid-cap  counterparts in 1998. As segments of the
technology industry have matured, larger companies have frequently gained market
share and dis proportionate  profitability as purchasing power, incumbency,  and
customer  preference  for fewer  vendors have  continued to rise in  importance.
These  trends were  pronounced  in the  personal  computer  and data  networking
segments,  where a few large com panies have  prospered to the  exclusion of all
others.  Further aiding the performance of large-cap  technology stocks has been
the  ongoing  popularity  of the stocks of the S&P 500 and S&P 500 Index  funds.
Finally,  the  disappointing   performance  of  large  consumer  and  industrial
companies,  which  have  suffered  profit  shortfalls  from the  Asian and South
American currency crises, has caused large-company fund managers to shift assets
into big technology  companies  that continue to meet Wall Street  expectations.
The end result of these trends has been a snowballing of valuations,  as already
expensive  stocks  attain  ever-higher  absolute  and  relative  valuations.  In
addition to large-cap  technology  companies,  Internet companies also performed
well.  However,  the Portfolio  generally avoided pure-play Internet  companies,
given their high  valuations,  often  negative cash flow,  and typically  cloudy
profitability outlooks.

   The Portfolio's  holdings in media stocks  negatively  affected  performance.
Although  fundamentals were favorable throughout the year and our media holdings
performed    reasonably    well,   they    underperformed    relative   to   the
largest-capitalization  technology stocks. The weakest area of the Portfolio was
the semiconductor-related  sector, which went through a serious recession in the
wake of the Asian financial  crisis.  However,  this sector's  fundamentals have
recently begun to improve. The top-performing area of the Portfolio was computer
hardware and  peripherals,  which was positively  affected by Year 2000 testing,
increased  demand  for  data  storage,  and  market-share  consolidation  in the
computer industry.

   In the  large-capitalization  area we remain  underweighted  relative  to the
technology  indices,  although  we do  own  significant  positions  in  industry
leaders. The Portfolio also holds many  mid-capitalization  technology companies
with excellent fundamentals that have gone unappreciated by the market. In 1999,
we believe that we will find attractive  opportunities in radio broadcasting and
cable television,  semiconductor and semiconductor  capital equipment companies,
integrated  circuit  design  software  companies,   mechanical  design  software
companies, and entertainment software companies.

   The past year was a difficult  one for  small-company  stocks.  The  greatest
influence  on  both  the  Portfolio  and the  small-cap  market  was an  ongoing
reduction  in  expectations  for  corporate   earnings   throughout  1998.  When
conditions are positive,  investors are generally willing to pay big premiums to
own the faster rate of earnings growth that small-cap  stocks  typically  enjoy.
However, when there is earnings uncertainty (as was the case in 1998), investors
avoid smaller companies,  regardless of their attractive relative valuations and
long-term growth prospects.

   In 1998,  small-cap  stocks  were at a  disadvantage  on both the  supply and
demand side of the equation when judged against larger-cap stocks. From a supply
standpoint, the stock market was headed toward a record year in terms of initial
public  offering  (IPO)  activity,  until it cracked in  mid-summer.  New equity
supply tends to disadvantage  small-cap  investors,  because most new issues are
for smaller companies.  When an IPO successfully comes to market, fund managers,
in  general,  become net  sellers  of other  small-cap  holdings  to pay for the
purchase.  In  addition,  most of the money from  individuals  that  poured into
stocks this year was invested in the largest stocks. Even the tremendous inflows
of money from foreign  investors  completely  ignored  small caps, as the global
"flight  to  quality"  benefited  only the  best-known  American  companies.  To
small-cap investors,  the supply/demand  equation became a vicious circle. Money
flowing into large-cap funds  (particularly index funds), went into the market's
largest  stocks,   causing  their  prices  to  rise.  With  corporate   earnings
uncertainty,  few  investors  wanted to buy small caps, an asset class with less
liquidity and poor recent relative performance.

   One area of strength in the market that has traditionally benefited small-cap
growth  stocks was  technology.  Unfortunately,  the majority of the  technology
sector's gains in 1998 were limited to large technology  leaders and speculative
pure-play Internet companies. Due to the Portfolio's small-cap mandate, we could
not take advantage of opportunities in large-cap  technology  stocks. And due to
our  investment  approach,  which  focuses on  fundamentals,  we would not chase
over-priced Internet stocks.

   We believe that small-cap  growth stocks are at such  attractive  valuations,
compared to their long-term growth  prospects,  that 1999 could be the year they
return to favor.  Many of the large-cap market leaders of the past few years may
find their earnings  under  continued  pressure due to ongoing global  financial
problems.  Small-company  stocks  derive the  majority  of their  earnings  from
domestic  sources,  and  should  therefore  should  do well in spite  of  global
difficulties.

   During the first half of 1998,  world markets rose strongly by about 25%, led
by Continental  Europe and fueled by expectations of lower inflation and falling
interest  rates.  After  mid-July,  the combination of the Russian debt default,
speculative    attacks    against    emerging   market    currencies,    and   a
worse-than-expected  economic  impact  from Asia on the rest of the world led to
sharp market corrections.  Then, in October, markets recovered as interest rates
were cut in many parts of the world and a coordinated program of support for the
world's financial system was implemented.

   During the year, the Portfolio's  bias for stocks with higher earnings growth
and a preference for Continental  European markets were major positive  factors.
However,   Asian  and  other  emerging  market  investments   dampened  relative
performance even though we had  significantly  reduced exposure to these markets
during the year.

   The  Portfolio  remained  broadly  invested in our four major growth  themes.
During the year, we reduced exposure to the Productivity  theme while increasing
exposure to the more stable  Quality-of-Life  theme, with its emphasis on health
care stocks. Our exposure to the Consumption theme remained virtually unchanged,
but we shifted our  geographical  focus away from Asia and the emerging  markets
toward  Europe.  In  general,  within each  theme,  we shifted  the  Portfolio's
investments toward those with greater earnings reliability.

   Profit  growth around the world has become more scarce and  uncertain,  which
has increased market volatility everywhere. However, a global economic recession
accompanied by prolonged deflation is unlikely, as there is still room for lower
interest rates. Meanwhile, the world has an excess of industrial capacity. Until
demand rises sufficiently to meet it, pricing power will be scarce in industrial
goods  markets.   The  service  sector   businesses  in  which  the  Portfolio's
investments are  concentrated are likely to perform well in such an environment.
During  times of subdued  profit  advance,  high-quality  growth  stocks tend to
perform  well.  And when there is a high level of near-term  uncertainty,  it is
appropriate  to look at the secular trends which are most likely to drive wealth
creation.  Accordingly,  we will continue to use a thematic approach to identify
superior growth opportunities in which to invest.

   During 1998,  smaller US companies  generally posted dis appointing  returns,
lagging well behind their larger  counterparts.  In the UK, this  divergence was
less  pronounced  than in the  US,  but was  nevertheless  significant,  and the
environment  there  remains  difficult  for small  caps.  Smaller  companies  in
Continental  Europe,  with the notable exception of Norway,  generally performed
well,  though  still  lagging  large  caps.  The  economic  background  in Japan
continued to deteriorate  throughout  the year as the economy  appeared to be in
the grip of deflation,

a banking  crisis,  and policy  paralysis.  Despite  this  environment,  smaller
companies in Japan  returned  18.7% in US dollar terms,  14% ahead of the return
from large companies.  Japan was the only one to see outperformance from smaller
companies.  Smaller companies in Asia,  excluding Japan, fell 14.2% during 1998,
underperforming large companies.

   The Portfolio's allocation to US equities rose from a low of 41.7% in January
to 52.7% at the end of December. For much of the year, the allocation was in the
mid-40% range, but we increased this allocation in the fourth quarter, given the
attractive combination of growth opportunities and valuation levels.

   The  Portfolio  maintained  a neutral  to  slightly  overweight  position  in
Continental Europe throughout the period,  starting the year at 22.1%, rising to
22.6% in June,  and ending the year at 19.0%.  During  the year,  the  Portfolio
reduced  exposure  to the more  cyclical  sectors  of the market  where  pricing
pressure is likely to be most damaging for smaller companies.

   The  Portfolio  was  underweighted  in Japan  for the  whole  period.  At the
beginning of the year, our allocation was 5.6% and rose to 6.5% by year-end.  In
the rest of Asia, the Portfolio  began the year  underweighted  and ended with a
neutral  weight  of  2.9%.  Signs  of  an  improved   economic   background  and
confirmation  of  improvements  at the corporate level need to be seen before we
will increase the Portfolio's allocation to this region.

   Volatility,  which was the defining characteristic of equity markets in 1998,
does not favor small caps.  The current  focus on large  companies may continue,
but with the  valuation  gap  between  large and  small  caps now  looking  very
stretched,  and earnings  forecasts in many regions  better for small  companies
than for large, the global small-cap market looks attractive as we begin 1999.

   In 1998, the technology industry significantly  outperformed the broad market
in most countries,  with US and European tech stocks leading the way.  Inventory
issues in the PC  market  early in the year led to  severe  underperformance  by
cyclical  technology  shares but, by the late autumn,  strong PC demand combined
with  constrained  production  produced  strong year-end  results.  The dramatic
growth of  Internet  usage  represented  perhaps  the  single  most  significant
contributor  to the growth of the  technology  market.  Consumer  enthusiasm for
getting  on-line drove heavy retail demand for PCs,  while the explosion in data
traffic  obliged  communications  carriers to upgrade and extend  their  network
infrastructure. Consequently, we have seen tremendous strength in the networking
and  communications  equipment  markets.  This was matched by growth in wireless
where   subscriber   growth,   particularly  in  Europe,   has  vastly  exceeded
expectations.

   Throughout  the year we  remained  heavily  focused  on the US as the  global
technology  leader and on Europe as the market that seems to be positioned for a
period of strong growth.  We maintained a modest  weighting in Asia and continue
to believe that the best investment prospects lie outside that region.

   With corporate  profit growth in the broad stock market  slowing  markedly in
the current  deflationary  climate, the exceptional growth rates being delivered
by technology companies are commanding ever-higher valuations. As we begin 1999,
the  industry's  absolute  fundamentals  are good and  continue to improve,  and
relative fundamentals are among the best seen in 15 years.

   The year began with  international  stock markets rising  strongly.  However,
this ended abruptly during the summer when Russia's default on its debt produced
significant  financial  consequences around the globe. During the third quarter,
stock markets fell sharply,  but rebounded  strongly  during the fourth quarter.
Inflation  remained  low,  causing  long-bond  yields to decline,  and  enabling
central banks around the world to respond quickly to the global financial crisis
by cutting short rates, a process that is likely to continue.

   UK markets  followed  the  fortunes of the rest of the world during the year,
falling  dramatically  from July highs, but recovering by year-end.  We remained
overweighted  in the UK as we viewed that market as a defensive  bet relative to
the rest of the world.  The Portfolio was heavily  overweighted  in  Continental
Europe  during the year,  which  contributed  positively to  performance.  Lower
interest  rates,  anticipation  of  the  European  Monetary  Union,  and  strong
forecasted  earnings growth helped lift these stocks higher in the first half of
the year, allowing Continental Europe to outperform most other regional markets.
The  Portfolio  will likely  maintain this  regional  overweighting  as economic
growth in Europe should be among the most resilient in the world.

   The Portfolio  maintained a very low weighting in Japan  throughout  the year
because we did not anticipate any near-term  economic  recovery in this troubled
market.  We do not expect a speedy solution to the banking crisis nor sufficient
stimulus to boost the economy,  and believe  significant  risks for the Japanese
market remain.  During the year, we maintained  minimal  exposure to the Pacific
markets,  which were down by 5.1% on average, and expect to remain underweighted
in this region over the near term. In other  emerging  markets,  which  suffered
greatly  in an  environment  of falling  commodity  prices  and  slowing  global
economic growth, we maintained only limited exposure.

   International  stock  markets  continue to look more secure as  interest-rate
reductions  boost  investor  sentiment.  But despite these  improvements,  risks
remain and markets must account for slower economic and corporate profit growth.
Within this context,  we expect continental  Europe, the UK, and select emerging
markets to offer attractive return potential,  as we believe corporate  earnings
have the greatest potential in these regions. In contrast, we believe that Japan
and the Pacific region will remain depressed over the near term.

   A very  unusual  combination  of events  forced a  liquidity  squeeze  on the
high-yield  market in 1998.  The global stock market decline which began in July
caused many high-yield issuers to lose another potential source of financing and
thus  much-needed  financial  flexibility.  Then, when rumors began to circulate
that Russia and a number of Asian countries would default on their debt,  mutual
funds with direct  emerging market  exposure faced  significant  redemptions and
sold their most  stable  assets --  domestic  high-yield  bonds -- to meet those
redemptions.  While the Portfolio had no direct  emerging market  exposure,  the
selling pressure created by those funds led to repricing of domestic  high-yield
issues.  Finally,   additional  downward  pressure  was  created  following  the
announcement of the bailout of Long-Term Capital  Management  (LTCM),  which had
many high-yield investments.  Unfortunately, because LTCM was so secretive about
its  holdings,  no one knew which  bonds  would be most  impacted,  so the whole
market repriced downward.

   In the fourth  quarter,  the  high-yield  market  rebounded,  for a number of
reasons.  The most  compelling was that bargain  hunters moved in to an oversold
market.  Mutual fund investors,  pension funds,  and insurance  companies poured
billions  of dollars  into the  attractively  priced  high-yield  market.  Other
important  factors  contributing to the rebound  included  Federal Reserve Board
Chairman Alan Greenspan's positive statements,  the Federal Reserve Board's rate
cuts, and the recovery of the equity markets.

   Defensive sectors such as cable, publishing, and gaming all did well in 1998.
The  hardest-hit  areas  of  the  high-yield  market  were  those  that  require
additional  funding to meet their respective  business plans.  Fortunately,  the
Portfolio's  exposure to those  issues was  minimal.  Another  area hit hard was
nursing homes. The prospective  payment system recently put in place has created
some  short-term  challenges in this area, but we think that there are long-term
opportunities  in  nursing  home  providers.  In our  opinion,  this  sector was
oversold in 1998.  During the year,  we increased  the  Portfolio's  exposure to
health care, paging, publishing, and rural cellular providers.

   A strong US economy,  featuring  modest gross domestic  product (GDP) growth,
low interest  rates,  and a federal  budget surplus should allow defaults in the
high-yield market to remain modest. In this environment, our investment strategy
remains  unchanged.  We prefer  domestic  issuers with  predictable  cash flows,
dominant market shares,  high cash flow margins (which are indicative of pricing
power),  and strong  management  teams.  We have no emerging market exposure and
avoid purchasing defaulted and distressed bonds.

   In 1998, the US economy expanded for the eighth year in a row. Low inflation,
continued  corporate earnings growth in a benign interest rate environment,  and
an investor  "flight to quality" all pushed US equity and  fixed-income  markets
higher.  On the equity side,  the movement to  securities  that were  considered
safer was  positive  for the biggest US stocks,  but caused a  narrowing  of the
market that  excluded  many stocks.  On the  fixed-income  side,  this trend was
positive for US  Treasuries,  as global demand for  securities  backed by the US
government  grew. US corporate  securities,  on the other hand,  did not fare as
well in comparison.

   While the  Portfolio  remains  well  diversified  among  industry  groups and
individual holdings,  we have reduced the number of holdings in the Portfolio to
focus on companies  with dividend  yields equal to, or greater than the S&P 500,
and  those  with  valuations  at the  lower end of their  industry  group.  This
approach   led   us   to    underweight    many   of   the    excessively-valued
large-capitalization  stocks that were hit the hardest by last  summer's  market
downturn.   During  the  year,   we   significantly   reduced  the   Portfolio's
international holdings because of ongoing global economic problems. We continued
to reduce the convertible securities in the Portfolio,  which helped to increase
returns  without   increasing   overall  risk.  We  also  increased  the  Fund's
fixed-income  holdings,  as we felt that real  interest  rates were  attractive.
However,  our  fixed-income  exposure was heavily  weighted to corporate  bonds,
which underperformed Treasuries.

   Due to our concerns  regarding  large-cap  equity  valuations,  we ended 1998
underweighted  in  equities.  With the strong  results in the equity  markets in
1998, our underweighting in stocks negatively impacted our relative performance.
If the stock market  corrects in 1999,  we would use the  opportunity  to add to
positions in high-quality companies at more attractive valuations.

   We continue to believe that the US economy is an attractive  environment  for
investing in financial markets.  We do not see any reason for a significant rise
in interest  rates in 1999 as long as  corporate  profits  and overall  economic
growth  continue to be  moderate.  Deflationary  concerns  outside the US should
benefit  the  fixed-income  marketplace.  Within the equity  markets,  we remain
cautious of the high  valuations  on many of the largest  stocks,  and fear that
much of this has been driven by liquidity factors, not fundamentals.  Therefore,
we are focusing on identifying  companies  whose  valuations  more fully reflect
their future  prospects,  and where we believe  there is a catalyst for earnings
acceleration going forward.

   The period under review was a difficult one for the Portfolio,  and for value
funds in general.  As  investors  worried  about  everything  from  deflationary
pressures in the US to devalued  currencies  in emerging  markets,  the largest,
most liquid growth companies in the US -- companies with proven track records of
growing  earnings  in  the  past  --  benefited  from  a  "flight  to  quality."
Large-capitalization growth stocks were among the year's biggest winners, but to
the exclusion of large-capitalization value stocks.

   The Portfolio's most heavily weighted sector,  financial stocks,  suffered to
an even  greater  degree  than the broader  market  during the  difficult  third
quarter,  which was  characterized by concerns and  uncertainties  regarding the
global  financial  crisis.  The  Portfolio's  performance  was also  hurt by the
strength in  technology  stocks in general and  Internet  stocks in  particular,
where a virtual mania developed.  This resulted in a speculative  trading market
that became extremely  divergent.  Value stocks, which are low priced, do not do
well in this type of environment.

   In 1999,  we expect a slowdown in domestic  gross  domestic  product (GDP) to
about 2.5 percent.  Trade should continue to come under pressure and there could
be a meaningful  decline in capital  spending,  resulting in a period of slowing
job  creation  and reduced  income  gains.  Unemployment  may rise  somewhat and
inflation should remain muted. We think one of the major  investment  themes for
1999 will be restructuring and consolidating, as managements continue to attempt
to grow  profits in a slow  growth  environment.  In  commodity  price-sensitive
businesses, this will slowly bring supply into better balance.

   The greatest  influence on both the Portfolio and the small-cap market was an
ongoing reduction in expectations for corporate  earnings  throughout 1998. When
conditions are positive,  investors are generally willing to pay big premiums to
own the faster rate of earnings growth that small-cap  stocks  typically  enjoy.
However,  during periods of earnings uncertainty (as in 1998),  investors do not
want to own smaller companies, regardless of valuations.

   We  responded  to this  environment  by  staying  focused  on our  investment
discipline.  We bought what we considered to be quality companies with favorable
long-term  return  prospects.  In retrospect,  a winning  strategy for small-cap
investors in 1998 would have been to emphasize  those  "concept"  companies that
have no earnings,  or high-tech companies where valuations are well above what a
traditional value investor is willing to pay. However,  we remained committed to
our long-term value approach to investing.  To change one's  investment style in
order to fit with what is working in the market  today is better  known as style
rotation, and it is something we will not do.

   The Portfolio benefited from having owned five companies that were taken over
during  1998.  While we do not buy stocks  simply  because we think they will be
taken over, takeovers are a logical outcome given that our investment process is
often focused on those companies that sell at a discount to their private market
value.

   We generally  avoid investing in companies where the movement in the price of
a  commodity  (gold,  oil,  interest  rates,  etc.)  far  outweighs  any  impact
management can make. However, we did add two energy-related  investments earlier
this year,  based on a discount to net asset value,  already  significant  price
declines,  unseasonably  mild weather for the prior year,  and potential  demand
recovery  in Asia.  While  these  investments  have not yet paid off, we believe
that, at some point, when energy prices come back, so will these stocks.

   Current  valuations  suggest  that  a  period  of  significant  catch-up  for
small-cap  stocks,  in general,  and small-cap value stocks,  in particular,  is
coming.  We are not  market  timers  and we do not know if 1999 will be the year
that these stocks will rebound.  But for  investors  seeking  long-term  capital
appreciation who can withstand  greater  volatility,  small-cap value remains an
attractive investment area.

+ Investments in mortgage-backed  securities are subject to principal  paydowns.
  As a result of prepayments  from refinancing or satisfaction of the underlying
  mortgage instruments, the average life may be less than the original maturity.
  This in turn may impact the ultimate yield realized from these investments.

++ Investments in mortgage-backed  securities are subject to principal paydowns.
   As a result of prepayments from refinancing or satisfaction of the underlying
   mortgage  instruments,  the  average  life  may be  less  than  the  original
   maturity.  This in turn may impact the  ultimate  yield  realized  from these

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1.  ORGANIZATION  --  Seligman  Portfolios,  Inc.  (the  "Fund") is an  open-end
diversified  management  investment company consisting of 14 separate portfolios
(the Portfolios):  Seligman Bond Portfolio ("Bond Portfolio"),  Seligman Capital
Portfolio  ("Capital  Portfolio"),  Seligman Cash  Management  Portfolio  ("Cash

Portfolio  ("International  Portfolio"),   Seligman  High-Yield  Bond  Portfolio
("High-Yield Bond Portfolio"),  Seligman Income Portfolio ("Income  Portfolio"),
Seligman Large-Cap Value Portfolio  ("Large-Cap Value Portfolio"),  and Seligman
Small-Cap Value Portfolio  ("Small-Cap Value Portfolio"),  each designed to meet
different  investment  goals.  Shares of the Fund are currently  provided as the
investment  medium  for  Canada  Life of  America  Variable  Annuity  Account  2
("CLVA-2"),  which is  offered  by Canada  Life  Insurance  Company  of  America
("CLICA"),  Canada Life of New York  Variable  Annuity  Account 2  ("CLNYVA-2"),
which is offered by Canada  Life  Insurance  Company of New York  ("CLNY"),  and
Canada Life of America Annuity Account 3 ("CLVA-3"),  which is offered by CLICA.
CLVA-2  and  CLNYVA-2  are  registered  as  unit  investment  trusts  under  the
Investment  Company Act of 1940,  as amended (the "1940 Act") and fund  variable
annuity  contracts  (the  "CLVA-2  Contracts")  issued  by  CLICA  and  CLNY and
distributed by Seligman Advisors,  Inc. (the  "Distributor")  (formerly Seligman
Financial  Services,  Inc.).  CLVA-3 is not  registered  or  regulated as a unit
investment  trust under the 1940 Act in reliance  on the  exemption  provided in
Section  3(c)(11) of the 1940 Act, and funds  variable  annuity  contracts  (the
"CLVA-3  Contracts") issued by CLICA and distributed by Seligman Advisors,  Inc.
CLVA-3  Contracts may be purchased  only by pension or  profit-sharing  employee
benefit  plans that  satisfy the  requirements  for  qualification  set forth in
Section 401 of the Internal Revenue Code of 1986, as amended. Shares of the Fund
are also provided as the investment  medium for other variable  annuity accounts
established by CLICA or its affiliates ("Canada Life Separate Accounts"). Shares
of  Bond,   Capital,CashManagement,CommonStock,   andIncomePortfolios  are  also
provided as the investment  medium for Seligman Mutual Benefit Plan (the "Mutual
Benefit  Plan"),  a  separate  account of MBLLife  Assurance  Corporation  ("MBL
Life").  However,  MBL Life has decided that it will not accept applications for
new contracts nor will it accept  additional  purchase  payments  under existing
contracts.  In  addition,  requests  for  transfers  of  amounts  to  its  Fixed
Accumulation Account from the Mutual Benefit Plan will not be accepted.

2.  SIGNIFICANT  ACCOUNTING  POLICIES  -- The  financial  statements  have  been
prepared in conformity  with  generally  accepted  accounting  principles  which
require  management to make certain estimates and assumptions at the date of the
financial  statements.  The  following  summarizes  the  significant  accounting
policies of the Fund:

   a. SECURITY  VALUATION  --Investments in US Government  andGovernment  Agency
   securities,  bonds, convertible securities, and stocks are valued at the most
   current market values or, in their absence,  at fair market values determined
   in accordance with procedures approved by the Board of Directors.  Securities
   traded on an  exchange  are  valued  at the last  sales  prices  or, in their
   absence  and in the  case  of  over-the-counter  securities,  at the  mean of
   closing bid and asked prices. Short-term holdings maturing in 60 days or less
   are valued at amortized cost.  Investments held by Cash Management  Portfolio
   are generally valued using the amortized cost method which  approximates fair
   value. Investments of certain other funds in the Seligman Group of Investment
   Companies purchased to offset the Cash Management  Portfolio's  liability for
   deferred directors' fees are valued at current market values.

   b. FOREIGN  SECURITIES -- The  Portfolios may invest up to 10% of their total
   assets in foreign securities (except Global Growth  Opportunities  Portfolio,
   Global  Smaller  Companies  Portfolio,   Global  Technology  Portfolio,   and
   International  Portfolio,  (together,  the "Seligman Henderson  Portfolios"),
   which may invest up to 100% of their  total  assets in  foreign  securities).
   Investments  in foreign  securities  will usually be  denominated  in foreign
   currencies,  and  the  Portfolios  may  temporarily  hold  funds  in  foreign
   currencies. The Portfolios may also invest in US dollar-denominated  American
   Depositary Receipts ("ADRs"),  American Depositary Shares ("ADSs"),  European
   Depositary Receipts ("EDRs"), Global Depositary Receipts ("GDRs"), and Global
   Depositary  Shares  ("GDSs").  ADRs and ADSs are issued by domestic  banks or
   trust  companies  and  evidence  ownership  of  securities  issued by foreign
   corporations.  ADRs  and  ADSs are  traded  on  United  States  exchanges  or
   over-the-counter and are not included in the 10% limitation.  EDRs, GDRs, and
   GDSs are  receipts  similar  to ADRs and ADSs  and are  typically  issued  by
   foreign banks or trust companies and traded in Europe.  The books and records
   of the Portfolios are maintained in US dollars.  Foreign currency amounts are
   translated into US dollars on the following basis:
       (i) market value of investment securities, other assets, and
           liabilities, at the daily rate of exchange as reported by a pricing
           service;
      (ii) purchases and sales of investment  securities,  income, and expenses,
           at the rate of exchange  prevailing on the  respective  dates of such
           transactions.

      The net asset values per share of  Portfolios  which invest in  securities
   denominated  in foreign  currencies  will be  affected by changes in currency
   exchange rates.  Changes in foreign  currency  exchange rates may also affect
   the value of dividends  and  interest  earned,  gains and losses  realized on
   sales of  securities,  and net  investment  income and gains,  if any,  to be
   distributed to shareholders of the Portfolios.  The rate of exchange  between
   the US dollar and other  currencies is determined by the forces of supply and
   demand in the foreign exchange markets.

                                     P-62

<PAGE>
                          SELIGMAN PORTFOLIOS, INC.

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

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

      Net  realized  foreign  exchange  gains  or  losses  arise  from  sales of
   portfolio securities, sales and maturities of short-term securities, sales of
   foreign  currencies,  currency gains or losses realized between the trade and
   settlement dates on securities transactions,  and from the difference between
   the amounts of dividends,  interest and foreign withholding taxes recorded on
   the Portfolios'  books, and the US dollar  equivalent of the amounts actually
   received or paid. Net unrealized foreign exchange gains and losses arise from
   changes  in the value of  portfolio  securities  and other  foreign  currency
   denominated  assets and liabilities at period end,  resulting from changes in
   exchange rates.

      The  Portfolios  separate  that  portion  of  the  results  of  operations
   resulting from changes in the foreign  exchange  rates from the  fluctuations
   arising  from  changes  in  the  market  prices  of  securities  held  in the
   portfolios.  Similarly,  the  Portfolios  separate  the  effect of changes in
   foreign  exchange  rates from the  fluctuations  arising  from changes in the
   market prices of portfolio securities sold during the period.

   c. FORWARD CURRENCY CONTRACTS -- The Seligman Henderson  Portfolios may enter
   into forward  currency  contracts in order to hedge their exposure to changes
   in foreign currency  exchange rates on their foreign portfolio  holdings,  or
   other amounts  receivable or payable in foreign currency.  A forward contract
   is a commitment to purchase or sell a foreign  currency at a future date at a
   negotiated  forward  rate.  Certain  risks may arise upon entering into these
   contracts from the potential inability of counterparties to meet the terms of
   their contracts. The contracts are valued daily at current exchange rates and
   any  unrealized  gain or loss is included in net unrealized  appreciation  or
   depreciation on translation of assets and liabilities  denominated in foreign
   currencies and forward currency contracts.  The gain or loss, if any, arising
   from the difference  between the settlement value of the forward contract and
   the closing of such  contract,  is included in net realized gain or loss from
   foreign currency transactions.  For federal income tax purposes, certain open
   forward currency contracts are treated as sold during the fiscal year and any
   gains or losses are recognized immediately. As a result, the amount of income
   distributable  to  shareholders  may vary  from  the  amount  recognized  for
   financial statement purposes.

   d. FEDERAL TAXES -- The Portfolios' policy is to comply with the requirements
   of the Internal Revenue Code applicable to Regulated Investment Companies and
   to  distribute  substantially  all of their  taxable  net income and net gain
   realized to shareholders.

   e.  SECURITY   TRANSACTIONS  AND  RELATED   INVESTMENT  INCOME   --Investment
   transactions are recorded on trade dates.  Interest income is recorded on the
   accrual  basis.  The  Portfolios  amortize  market  discounts and premiums on
   purchases  of  portfolio  securities.  Dividends  receivable  and payable are
   recorded on  ex-dividend  dates,  except that certain  dividends from foreign
   securities  where the ex-dividend  dates may have passed are recorded as soon
   as the Fund is informed of the dividend.

   f.  REPURCHASE   AGREEMENTS   --The  Portfolios  may  enter  into  repurchase
   agreements  with  commercial  banks  and  with  broker/dealers  deemed  to be
   creditworthy  by  J.  & W.  Seligman  &  Co.  Incorporated  (the  "Manager").
   Securities purchased subject to repurchase  agreements are deposited with the
   Portfolios'   custodians  and,  pursuant  to  the  terms  of  the  repurchase
   agreements,  must have an aggregate market value greater than or equal to the
   repurchase price, plus accrued interest,  at all times.  Procedures have been
   established to monitor,  on a daily basis, the market value of the repurchase
   agreements' underlying securities to ensure the existence of the proper level
   of collateral.

   g. EXPENSE  ALLOCATIONS -- Expenses  directly  attributable to each Portfolio
   are charged to such Portfolio,  and expenses that are applicable to more than
   one Portfolio are allocated among them.

   h.  DISTRIBUTIONS  TO SHAREHOLDERS  -- The treatment for financial  statement
   purposes of distributions  made during the year from net investment income or
   net  realized  gains may differ  from their  ultimate  treatment  for federal
   income tax purposes. These differences primarily are caused by differences in
   the timing of the  recognition  of certain  components of income,  expense or
   capital gain and the  recharacterization  of foreign exchange gains or losses
   to either  ordinary  income or realized  capital gain for federal  income tax
   purposes.   Where  such  differences  are  permanent  in  nature,   they  are
   reclassified  in the  components  of  net  assets  based  on  their  ultimate
   characterization for federal income tax purposes.  Any such  reclassification
   will have no effect on net assets, results of operations, or net asset values
   per share of the Portfolios.

3.  PURCHASES  AND  SALES OF  SECURITIES  --Purchases  and  sales  of  portfolio
securities,  excluding US Government obligations and short-term investments, for
the year ended December 31, 1998, were as follows:

           PORTFOLIO                          PURCHASES           SALES

   For the year ended  December 31, 1998,  purchases  and sales of US Government
obligations  were  $3,112,503  and  $3,205,188,   respectively,   for  the  Bond
Portfolio,  and  $3,068,155  and  $1,597,913,   respectively,   for  the  Income
Portfolio.

   Identified cost of investments sold is used for both financial  statement and
federal income tax purposes.

   At December 31, 1998, the cost of investments for federal income tax purposes
was substantially the same as the cost for financial reporting purposes. The tax
basis gross unrealized  appreciation  and depreciation of portfolio  securities,

4.  MANAGEMENT  FEE,  ADMINISTRATIVE  SERVICES,  AND OTHER  TRANSACTIONS  -- The
Manager  manages  the  affairs  of the Fund and  provides  or  arranges  for the
necessary personnel and facilities. The Manager's fee, which is calculated daily
and payable  monthly,  is equal to 0.40%,  on an annual basis,  of each of Bond,
Capital, Cash Management, Common Stock, and Income Portfolios' daily net assets;
equal to 0.75%,  on an annual basis, of each of  Communications  and Information
and Frontier  Portfolios' daily net assets;  equal to 1.00%, on an annual basis,
of each of the Seligman  Henderson  Portfolios'  daily net assets;  and equal to
0.50%, on an annual basis, of High-Yield Bond Portfolio's daily net assets.  The
Manager's fee for the Large-Cap  Value  Portfolio is equal to 0.80% per annum of
the first $500 million of average daily net assets,  0.70% per annum of the next
$500  million of average  daily net assets,  and 0.60% per annum in excess of $1
billion of average daily net assets of the Portfolio.  The Manager's fee for the
Small-Cap  Value Portfolio is equal to 1.00% per annum of the first $500 million
of average daily net assets, 0.90% per annum of the next $500 million of average
daily net assets,  and 0.80% per annum in excess of $1 billion of average  daily
net assets of the Portfolio.

   Prior to July 1, 1998,  Seligman  Henderson  Co., an entity owned 50% each by
the Manager and Henderson  International,  Inc., a subsidiary of Henderson  plc,
supervised  and  directed  the  global  investments  of the  Seligman  Henderson
Portfolios.  Pursuant to subadvisory  agreements  with the Manager,  the Manager
paid  Seligman  Henderson Co. 0.90% per annum of the average daily net assets of
each of the Seligman Henderson Portfolios.

   On March 30, 1998,  AMP Limited,  an Australian  life insurance and financial
services  company,  completed an acquisition of Henderson plc, which resulted in
the  termination  of the Fund's  subadvisory  agreements.  The  Fund's  Board of
Directors  approved interim  subadvisory  agreements  pursuant to which Seligman
Henderson Co.  continued to supervise and direct the global  investments  of the
Seligman Henderson Portfolios. The Fund's directors also approved a proposed new
subadvisory  agreement pursuant to which Henderson Investment Management Limited
(the  "Subadviser"),  a wholly-owned  subsidiary of Henderson plc, would replace
Seligman Henderson Co. as subadviser to the Seligman Henderson  Portfolios,  and
be respon-

sible for furnishing investment advice, research, and assistance with respect to
their non-US  investments.  Under the new agreement,  the Manager is responsible
for the US  investments  of the Seligman  Henderson  Portfolios  and has overall
responsibility  for management of the  Portfolios.  Both the interim and the new
subadvisory agreements were approved by votes of the shareholders of each of the
Seligman  Henderson  Portfolios  on June 30,  1998.  Under  the new  subadvisory
agreement,  the Manager pays the  Subadviser a  subadvisory  fee for each of the
Seligman  Henderson  Portfolios  at a rate of 0.50%  per  annum  of the  average
monthly assets under the Subadviser's supervision.

   The Manager has agreed to reimburse  expenses,  other than the management fee
that  exceed  0.20% per annum of the  average  daily net assets of each of Bond,
Capital, Common Stock, Communications and Information, Frontier, High-Yield Bond
and Income  Portfolios.  The Manager,  at its discretion and until it determines
otherwise,  has elected to waive all of its fee for,  and  reimburse  all of the
expenses of, the Cash Management  Portfolio.  The Manager and Seligman Henderson
Co.  (through June 30, 1998) have agreed to reimburse  expenses,  other than the
management  fee, which exceed 0.40% per annum of the average daily net assets of
each of the Seligman Henderson Portfolios.  The Manager, at its discretion,  has
also agreed to reimburse all expenses,  other than the  management  fees, of the
Large-Cap   Value  and  Small-Cap  Value   Portfolios.   The  amounts  of  these
reimbursements  for the  year  ended  December  31,  1998 are  disclosed  in the
Statements of Operations.

   Compensation  of all officers of the Fund,  all directors of the Fund who are
employees or consultants  of the Manager,  and all personnel of the Fund and the
Manager is paid by the Manager or by Henderson plc.

   The  Distributor,  agent for the  distribution of the CLVA-2 Contracts and an
affiliate  of the Manager,  received  concessions  of $228,662  from Canada Life
Insurance  Company of America and $15,703 from Canada Life Insurance  Company of
New York, after commissions paid to dealers for the sale of shares of the Fund.

   Certain  officers and  directors of the Fund are officers or directors of the
Manager and the Distributor.

   The Fund has a  compensation  arrangement  under which  directors who receive
fees may elect to defer  receiving such fees.  Directors may elect to have their
deferred fees accrue  interest or earn a return based on the  performance of the
other funds in the Seligman Group of Investment Companies. The cost of such fees
and earnings  accrued thereon is included in directors'  fees and expenses,  and
the  accumulated  balances  thereof at December 31, 1998,  are included in other
liabilities.  Deferred fees and related accrued  earnings are not deductible for
the federal income tax purposes until such amounts are paid.

5. LOSS  CARRYFORWARD  -- At December 31, 1998, the Frontier  Portfolio,  Global
Growth Opportunities  Portfolio,  and Global Smaller Companies Portfolio had net
capital  loss  carryforwards  for federal  income tax  purposes  of  $1,123,646,
$376,086 and $308,768,  respectively,  which are  available  for offset  against
future taxable net gains.  These net capital loss  carryforwards  will expire in
2006.  Accordingly,  no capital  gain  distributions  are expected to be paid to
shareholders  until  net  capital  gains  have  been  realized  in excess of the
available capital loss carryforwards.

6. OUTSTANDING  FORWARD EXCHANGE CURRENCY CONTRACTS -- At December 31, 1998, the
Fund  had  outstanding  forward  exchange  currency  contracts  to sell  foreign
currencies as follows:

* Commencement of operations.

8.  COMMITTED  LINE OF  CREDIT  --Effective  July 1,  1998,  Communications  and
Information,  Frontier,  Global Growth Opportunities,  Global Smaller Companies,
Global  Technology,  International,  and High-Yield Bond  Portfolios  terminated
their $12 million  committed  line of credit  facility and all of the Portfolios
except  the  Cash  Management  Portfolio,  entered  into a  joint  $800  million
committed  line of  credit  that is  shared  by  substantially  all funds in the
Seligman Group of Investment Companies.  Each Portfolio's borrowings are limited
to 10% (5% for the Seligman Henderson Portfolios) of its net assets.  Borrowings
pursuant to the credit  facility  are subject to interest at a rate equal to the
overnight  federal funds rate plus 0.50%. Each Portfolio incurs a commitment fee
of 0.08% per annum on its share of the unused  portion  of the credit  facility.
The credit facility may be drawn upon only for temporary purposes and is subject
to certain other customary restrictions.  The credit facility commitment expires
one year from the date of the agreement but is renewable with the consent of the
participating  banks.  To date,  none of the  Portfolios  have borrowed from the
credit facility.

9.  SELIGMAN  MUTUAL  BENEFIT  PLAN -- On  December  31,  1998,  MBL  Life  sold
substantially  all of its general account life insurance and annuity  businesses
to  SunAmerica,  Inc.  The Order  from the  Superior  Court of New  Jersey  (the
"Order")  approving the  transaction  provided for the termination of the Mutual
Benefit  Plan.  The  Order  authorizes  MBL  Life  to take  any and all  actions
necessary  to  facilitate   the   termination   of  the  Mutual   Benefit  Plan.
Contractholders  will be given the  opportunity to exchange their  contracts for
contracts issued by other insurance companies until June 30, 1999. Any contracts
remaining  with MBL Life at June 30, 1999 will be  terminated  and MBL Life will
pay out their account value.

   At December 31, 1998, the Mutual Benefit Plan assets held in the Fund were as
follows:

               Bond Portfolio                                    $ 1,650,594
               Capital Portfolio                                   5,139,844
               Cash Management Portfolio                             833,299
               Common Stock Portfolio                             15,020,603
               Income Portfolio                                    3,742,406

   Because  the  Manager   currently  limits  the  expenses  incurred  by  these
portfolios, the withdrawal of Mutual Benefit Plan assets is not expected to have
a  significant  impact on the ratio of expenses to average net assets for any of
these portfolios.

FINANCIAL HIGHLIGHTS
- --------------------------------------------------------------------------------

   The  tables  below  are  intended  to help you  understand  each  Portfolio's
financial  performance  for the past five years or from its  inception,  if less
than five years.  Certain  information  reflects  financial results for a single
share  that was held  throughout  the  periods  shown.  Per  share  amounts  are
calcuated using average shares  outstanding.  "Total return" shows the rate that
you would have earned (or lost) on an investment in each Portfolio, assuming you
reinvested all your dividends and capital gain  distributions.  Total returns do
not reflect any  administrative  fees and asset  based  sales  charges  that are
associated with variable annuity  contracts,  and are not annualized for periods
of less than one year.

REPORT OF THE INDEPENDENT AUDITORS
- -------------------------------------------------------------------------

The Directors and Shareholders,
Seligman Portfolios, Inc.:

We have audited the accompanying statements of assets and liabilities, including
the  portfolios  of  investments,  of  Seligman  Portfolios,  Inc.  (comprising,
respectively,  the Seligman Bond Portfolio, Seligman Capital Portfolio, Seligman
Cash   Management   Portfolio,   Seligman  Common  Stock   Portfolio,   Seligman
Communications and Information Portfolio,  Seligman Frontier Portfolio, Seligman
Henderson  Global Growth  Opportunities  Portfolio,  Seligman  Henderson  Global
Smaller Companies  Portfolio,  Seligman  Henderson Global Technology  Portfolio,
Seligman Henderson International Portfolio,  Seligman High-Yield Bond Portfolio,
Seligman Income  Portfolio,  Seligman  Large-Cap Value  Portfolio,  and Seligman
Small-Cap  Value  Portfolio,  collectively  referred  to as  the  "Fund")  as of
December 31, 1998, and the related  statements of operations,  the statements of
changes in net  assets,  and the  financial  highlights  for each of the periods
indicated therein.  These financial  statements and financial highlights are the
responsibility  of the Fund's  management.  Our  responsibility is to express an
opinion on these  financial  statements  and financial  highlights  based on our
audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements and financial  highlights.  Our procedures  included  confirmation of
securities owned as of December 31, 1998, by correspondence  with the custodians
and brokers. An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion,  the financial  statements and financial  highlights referred to
above present fairly, in all material  respects,  the financial position of each
of the respective portfolios constituting Seligman Portfolios,  Inc. at December
31, 1998, the results of their operations,  the changes in their net assets, and
the financial  highlights for each of the indicated periods,  in conformity with
generally accepted accounting principles.
