Dear Investors:

We are  pleased to provide  you with this  report on the  operations  of the JNL
Series Trust for the six-month period ended June 30, 1999.

In the United States,  strong economic growth and  dramatically  rising interest
rates marked the first half of 1999. The strong economic growth heightened fears
about the prospect for higher  inflation,  but the Federal Reserve tempered some
of  those  concerns  when  it  increased  its  short-term  lending  rate  at the
conclusion of its mid year Federal Open Market Committee meeting on June 30.

The United  States  stock market  posted  gains during the period.  Continuing a
trend,  the gains in the stock  market  during the first  quarter were driven by
stocks of large capitalization companies. The market shifted dramatically in the
second  quarter,  when  small- and  mid-cap  stocks  significantly  outperformed
large-cap stocks, and the focus changed from growth stocks to value stocks.

The dramatic rise in interest rates created an unfavorable  environment for U.S.
bonds  during the first half of the year.  Higher  interest  rates  affected all
market  sectors as  Treasuries,  mortgages and  corporates  all posted  negative
returns during the period.  Lower credit quality bonds performed better than the
higher credit quality bonds.

International  stock  markets  strengthened  during  the  period,  supported  by
economic  recoveries  in Asia and the emerging  markets.  European  markets held
steady.

The JNL Series Trust offers a selection of Series,  each with its own investment
objective and  strategies.  The  performance of each Series is influenced by its
investment  objective and the investment style of its money manager,  as well as
the market  environment.  We hope that the selection of Series in the JNL Series
Trust  allows  you the  opportunity  to  create  a  portfolio  that  meets  your
investment objectives and needs.

Thank you for your continued confidence in our products and services.  We strive
to provide successful investment vehicles for your financial goals and hope that
you are pleased with the performance of the JNL Series Trust.

Respectfully,

/s/ Andrew B. Hopping

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/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.

                                JNL SERIES TRUST
            NOTES TO THE FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

     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.

     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.

            NOTES TO THE FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- --------------------------------------------------------------------------------

     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.

     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 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.
