Dear Contract Owner:

   J. & W. Seligman & Co. Incorporated (Seligman), as Manager of Seligman
Portfolios, Inc. (the Fund), is pleased to provide the enclosed unaudited report
for the six months ended June 30, 1999.

   Over the past six months, the global economic outlook continued to improve
and the US economy entered its ninth year of expansion. With this sustained
growth in America, several inflation indicators finally began showing modest
cautionary signals, causing the Federal Reserve Board to raise the federal funds
rate by 25 basis points in June. Following the Fed's meeting, common stock
prices rallied. International equity indices also generally rose in keeping with
the developing global growth backdrop. Fixed-income instruments, however,
experienced price declines as a result of rising interest rates.

   Looking ahead, we believe that US economic growth will continue, but that the
pace will moderate, in keeping with the Fed's intentions. For that matter, the
Fed may raise interest rates further if inflation indicators move higher in any
sustained fashion. We expect that the world economy will continue to recover and
to grow. In such an environment, US and international equities are likely to
perform well. Further, we believe that once interest rates reflect the Fed
adjustments, fixed-income obligations will begin moving within a trading range.

   As the millennium approaches, we have become concerned that the media's focus
on the Year 2000 (Y2K) computer issue, and the fears that this attention may
spark, will cause some investors to take actions that are not in their best
long-term interests. In our view, the primary danger to investors is losing
sight of their long-term financial goals and altering their portfolios and asset
allocations in an attempt to respond to the confusion surrounding this issue. In
the US, governments and businesses have committed substantial resources to this
issue and, while there may be scattered inconveniences, we believe that the US
will enter the year 2000 relatively seamlessly, and that much of the rest of the
developed world is also well positioned to deal with the new millennium.

   For the past several years, Seligman has been working to ensure that
shareholders do not experience any Y2K-related inconveniences. We are pleased to
report that the early start has paid off. During the spring of this year,
Seligman participated in Y2K testing conducted by the Securities Industry
Association. These tests were completed without any Y2K-related problems on the
part of Seligman. Tests with key service providers were also conducted, all of
which were successfully completed in a Y2K environment.

   Thank you for your continued support of Seligman Portfolios, Inc. We look
forward to serving your investment needs for many years to come.

                                            Respectfully,

                                            /s/ William C. Morris

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

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

Assurance Corporation ("MBL Life").

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 and Government 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.

     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

                                    -- P-54 --

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


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 six months ended June 30, 1999, were as follows:

and federal income tax purposes.

was substantially the same as the cost for financial reporting purposes. The tax

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  Growth Portfolio is equal to 0.70% per annum of
the first $1 billion of average daily net assets, 0.65% per annum of the next $1
billion, and 0.60% per annum in excess of $2 billion of average daily net assets
of the Portfolio.  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.

     Effective  July 1,  1998,  Henderson  Investment  Management  Limited  (the
"Subadviser"),  became  adviser  to the  Seligman  Henderson  Portfolios  and is
responsible  for furnishing  investment  advice,  research,  and assistance with
respect  to their  non-US  investments.  Under the  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  Subadivser  is  a  wholly-owned  subsidiary  of
Henderson  plc,  which is an indirect  subsidiary of Amp Limited,  an Australian
life insurance and financial services company.

     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 has 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 Growth, Large-Cap Value and Small-Cap
Value Portfolios.  The amounts of these  reimbursements for the six months ended
June 30, 1999 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 the Subadviser.

     The Distributor,  agent for the distribution of the CLVA-2 Contracts and an
affiliate  of the  Manager,  received  concessions  of $89,682  from Canada Life
Insurance  Company of America and $7,404 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 June 30,  1999,  are  included  in other
liabilities.  Deferred fees and related accrued  earnings are not deductible for
federal income tax purposes until such amounts are paid.

5. CAPITAL 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 capital 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 June 30, 1999, the Fund
had outstanding  forward exchange currency contracts to purchase or sell foreign
currencies as follows:

* Commencement of operations.

8. COMMITTED LINE OF CREDIT -- All of the Portfolios, except the Cash Management
Portfolio,  are  participants  in a joint $750 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,  MBLLife  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  authorized  MBL  Life  to take  any and all  actions
necessary  to  facilitate   the   termination   of  the  Mutual   Benefit  Plan.
Contractholders  were given the  opportunity  to exchange  their  contracts  for
contracts  issued by other insurance  companies until June 30, 1999. At June 30,
1999, there were no remaining contracts.

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.
