ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

     On December 1, 2003, DST Systems, Inc. ("DST") and Janus Capital Group Inc.
("Janus") completed their previously  announced share exchange.  Under the terms
of the  transaction,  Janus  exchanged  32.3 million  shares of DST common stock
(27.9 % of the  outstanding  shares) for 100% of the stock of a DST  subsidiary,
DST Output Marketing Services,  Inc. ("OMS"), which was previously part of DST's
Output Solutions segment.  At the time of the exchange,  OMS held a printing and
graphics  design   business  valued  at  $115  million,   as  well  as  cash  of
approximately  $999  million.  The  transaction  was  structured  as a  tax-free
exchange under Section 355 of the Internal Revenue Code.

     Janus  and DST had  agreed  that the  exchange  value of the DST  shares at
closing  was to be  determined  based on the average  price of DST common  stock
during the twenty  trading day period  prior to the closing of the  transaction,
but not less than $30.00 per share nor more than $34.50 per share. The per share
value determined pursuant to that agreement was $34.50.

     Upon completion of the transaction, Janus still owned 7.4 million shares of
DST common stock  (approximately 9% of the outstanding shares) but granted DST a
proxy to vote those shares.

ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS

(b) Pro Forma Financial Statements


               UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS

     The following unaudited pro forma condensed financial  statements are based
on the  historical  consolidated  balance sheets and statements of income of DST
and OMS, adjusted to give effect to the Exchange.

     The unaudited pro forma condensed  statements of income for the nine months
ended  September  30, 2003 and for the year ended  December 31, 2002 reflect the
historical results of operations of DST less the historical operations of OMS as
if the Exchange occurred at the beginning of the earliest period presented.

     The unaudited pro forma  condensed  combined  balance sheet as of September
30, 2003 assumes that the Exchange occurred as of that date.

     The following unaudited pro forma condensed financial  statements have been
prepared  from,   and  should  be  read  in  conjunction   with  the  historical
consolidated  financial  statements  and notes  thereto of DST  appearing in its
Annual  Report on Form 10-K for the year ended  December 31, 2002 and  Quarterly
Report on Form 10-Q for the quarter ended September 30, 2003, and the historical
combined  financial  statements and notes of OMS for the year ended December 31,
2002 included as exhibits to the proxy statement dated November 13, 2003.  These
unaudited  pro  forma   condensed   financial   statements   are  presented  for
illustrative  purposes only and are not necessarily  indicative of the operating
results or financial  position  that would have  occurred had the Exchange  been
consummated  on the dates  indicated in the  preceding  paragraphs,  and are not
necessarily  indicative of the future operating results or financial position of
DST.

           NOTES TO UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS

1.   On August 25, 2003, DST, OMS (a  wholly-owned  subsidiary of DST) and Janus
     entered into a Share  Exchange  Agreement that provides for the exchange of
     all of the  outstanding  shares of OMS owned by DST for 32.3 million shares
     of DST Common  Stock  owned by Janus.  The  Exchange  has been  designed to
     comply with  Section 355 of the Internal  Revenue  Code,  accordingly,  DST
     should not incur  income tax relating to the  split-off  of OMS.  Under the
     terms of the Share Exchange Agreement,  the Janus DST Shares will be valued
     at a price  ranging  from $30.00 to $34.50 per share,  based on the average
     closing  price  for  the 20  trading  days  preceding  the  Closing  of the
     Exchange.  DST will equalize the difference between the negotiated value of
     OMS of $115.0 million and the gross transaction value, which can range from
     $969.0 million to $1,114.4  million,  with cash ranging from $854.0 million
     to $999.4 million (Additional Assets).

     On November  28,  2003,  DST held a special  shareholder  meeting.  At that
     meeting, DST shareholders  approved the previously announced Share Exchange
     Agreement,  dated  August 25, 2003 by and among DST,  DST Output  Marketing
     Services, Inc. and Janus Capital Group Inc. The Exchange closed on December
     1, 2003.  Based on the average  closing price of DST Common Stock and terms
     within  the Share  Exchange  Agreement,  $34.50  was used as the DST Common
     Stock share price.  DST contributed  cash of $999.4 million to equalize the
     difference  between the  negotiated  value of OMS of $115.0 million and the
     final  transaction  value  determined  for  the  Exchange.  For  accounting
     purposes,  the treasury stock is recorded at the implied  transaction value
     ($1,126.0 million),  which represents the value of OMS on the Exchange date
     and the  contributed  cash.  Immediately  after the Exchanged  closed,  the
     shares received were retired.

2.   Reflects  the  historical  operations  of OMS for  the  nine  months  ended
     September  30,  2003  and for the  year  ended  December  31,  2002 and the
     financial position of OMS at September 30, 2003, respectively.

3.   Reflects  the annual  interest  expense  of $41.5  million  resulting  from
     funding the  contribution of the Additional  Assets ($999.4 million) to OMS
     based on $34.50  per share of DST Common  Stock at  Closing.  The  interest
     expense for the nine month period ended September 30, 2003 is $31.2 million
     based on the following  calculation.  DST funded the  Additional  Assets as
     follows (dollars in millions):

     On August  12,  2003,  DST  completed  its  offering  of $840.0  million in
     Convertible Senior Debentures due 2023. For the nine months ended September
     30,  2003,  the DST  historical  numbers  include  $5.2 million in interest
     expense  related to the  convertible  notes and debt issuance costs. If the
     convertible  notes were issued as of January 1, 2002, the interest  expense
     related to the convertible notes would have been $27.5 million for the nine
     months ended September 30, 2003. The debt issuance costs represents 2.5% of
     the offering paid to the underwriters.



     The DST secured revolving credit facility is subject to a variable interest
     rate.  The effect of a 1/8%  variance in the interest rate on net income is
     $0.2 million based on a transaction value of $34.50 per share.

     An additional  $500.4  million was borrowed to help fund the $999.4 million
     in Additional Assets related to the Exchange. Of the additional borrowings,
     $320.0  million was used to finance  existing  debt and $180.4  million was
     used to fund the Exchange. The $320.0 million was needed due to DST using a
     portion of the  convertible  notes proceeds to payoff  existing debt at the
     time of the Convertible Notes offering.

4.   Reflects  the  income  tax  effects  of the pro forma  adjustments  for the
     Additional Assets at DST's statutory income tax rate of 39%.

5.   Reflects the reduction in average and diluted  shares  outstanding  of 32.3
     million shares in accordance with the Share Exchange Agreement.

6.   The  accompanying  pro forma income  statements do not reflect an estimated
     $114.3  million  gain  expected  to be  realized  from the  Share  Exchange
     Agreement.  The  gain  has  not  been  reflected  in the pro  forma  income
     statements  given the  non-recurring  nature of the  gain.  For  accounting
     purposes,  approximately  29.0  million  shares were  allocated to the cash
     portion of the Exchange and approximately 3.3 million shares were allocated
     to the value of OMS.  The  shares  allocated  to OMS are  valued at $37.97,
     which was the closing price of DST Common Stock as of December 1, 2003.

     The  accompanying pro forma balance sheet reflects the net gain in retained
     earnings as of September 30, 2003 and reflects the following (in millions):

            Net gain on transaction                              $  114.3
                                                             ===================

     The $0.2  million  deferred  tax asset is shown as an  adjustment  to other
     assets in the accompanying pro forma balance sheet.

7.   The debentures are convertible under certain  circumstances  into shares of
     DST Common Stock per $1,000 original  principal  amount of debentures at an
     initial  conversion rate of 20.3732  shares,  each subject to adjustment in
     certain events. This is equivalent to an initial conversion price of $49.08
     per  share  for the  debentures.  Upon  conversion,  DST has the  right  to
     deliver,  in lieu of DST Common Stock,  cash or any combination of cash and
     DST Common Stock. If the conversion criteria were met, the debentures would
     be  convertible  to  17,113,488  shares  of DST  Common  Stock.  Since  the
     conversion  criteria  is not  met,  the  shares  are not  reflected  in the
     earnings per share.  Management  currently intends to pay cash in the event
     the debt is put.
