Exhibit 99.1.


United States Steel Announces Filing For Exchange Offer


PITTSBURGH, Oct. 12 -- United States Steel LLC announced today that it has filed
with the Securities and Exchange Commission a Registration Statement relating to
the issuance of up to $365 million of Senior Quarterly Income Debt Securities
due 2031 ("SQUIDS") to be offered in exchange for outstanding 6.5% Cumulative
Convertible Preferred Stock of USX Corporation, 6.75% Convertible Cumulative
Quarterly Income Preferred Securities of USX Capital Trust I and 8.75%
Cumulative Monthly Income Preferred Shares, Series A of USX Capital LLC. The
total face amount outstanding of the three securities is approximately $568
million and if more than $365 million face amount is tendered, there will be a
proration.

Pending the separation of U.S. Steel and Marathon, the SQUIDS will be
unconditionally guaranteed by USX Corporation. Upon the separation, the USX
guarantee will no longer be applicable and United States Steel will be the sole
obligor of the SQUIDS.

The Dealer Manager for the exchange offers is Goldman, Sachs & Co.

The Prospectus that is part of the Registration Statement contains the following
updated Outlook for United States Steel:

  While over the last few months domestic orders for steel had strengthened  and
prices  had  stabilized,  our  order rate for the fourth  quarter  is  currently
running lower than our third quarter rate. In the third quarter, Domestic  Steel
shipments  totaled 2.6 million net tons and average realized prices  were  lower
than  the  second  quarter primarily due to changes in mix, including  decreased
sales  of  tubular and plate products. In the fourth quarter, we expect Domestic
Steel  shipments  to be approximately 2.3 million net tons and average  realized
prices to be about flat compared to the third quarter. In light of expected slow
market conditions in the fourth quarter, we plan to advance the schedule  for  a
maintenance outage on the Gary Works No. 6 blast furnace.

     On May 31, 2001, a major fire damaged the cold-rolling mill at USS-POSCO,
which is fifty percent owned by United States Steel. Damage was predominantly
limited to the cold-rolling mill area of the plant. USS-POSCO maintains
insurance coverage against such losses, including coverage for business
interruption. The mill is expected to resume production in the first quarter of
2002, although full production may not be achieved until mid-2002. Until such
time, the plant will continue customer shipments using cold-rolled coils from
United States Steel and POSCO as substitute feedstock.

     For  USSK,  third quarter shipments totaled approximately 1.0  million  net
tons,  down  slightly  from shipments of 1.1 million  net  tons  in  the  second
quarter, and average realized prices were higher than in the second quarter.  In
the  fourth quarter, we expect shipments to be slightly lower than in the  third
quarter and average realized prices to be comparable to the third quarter. Based
on  continued improvement in production performance since acquisition, USSK  raw
steel  production capability for the second half of 2001 has been  increased  to
2.5 million net tons, for an annualized rate of 5.0 million net tons.

     For  the  full  year 2001, total shipments are expected to be approximately
13.5 to 13.8 million net tons with Domestic Steel shipments of approximately  10
million  net  tons and USSK shipments of approximately 3.5 to  3.8  million  net
tons.

     For  the longer term, domestic shipment levels and realized prices will  be
influenced by the strength and timing of a recovery in the manufacturing  sector
of  the  domestic  economy, levels of imported steel and  production  capability
changes  by  domestic competitors. Many factors, including developments  flowing
from  the events of September 11, will determine the strength and timing of such
recovery and the other factors. For USSK, economic and political developments in
Europe  and  elsewhere  will impact USSK's results of  operations  in  2002  and
thereafter.

     United  States  Steel  owns  a  16% equity method  investment  in  Republic
Technologies  International,  LLC  (``Republic'')  through  USX's  ownership  in
Republic  Technologies International Holdings, LLC, which is the sole  owner  of
Republic.  Republic  is a major purchaser of raw materials  from  United  States
Steel  and the primary supplier of rounds for Lorain Tubular. On April 2,  2001,
Republic  filed  to  reorganize under Chapter 11 of the  U.S.  Bankruptcy  Code.
Republic has continued to supply the Lorain mill since filing for bankruptcy and
no supply interruptions are anticipated. United States Steel's carrying value of
this investment in Republic has been reduced to zero. Upon Republic's filing for
bankruptcy,  United States Steel accrued a charge for a substantial  portion  of
the  receivables  due  from Republic. At June 30, 2001,  United  States  Steel's
remaining  pre-petition financial exposure to Republic, after recording  various
losses and reserves, totaled approximately $30 million.

     The above discussion includes forward-looking statements concerning
shipments, pricing, and equity investee performance. These statements are based
on assumptions as to future product demand, prices and mix, and production.
Steel shipments and prices can be affected by imports and actions of the U.S.
Government and its agencies pertaining to trade, domestic and international
economies, domestic production capacity, and customer demand. Factors which may
affect USSK results are similar to domestic factors, including excess world
supply and foreign currency fluctuations, and also can be influenced by matters
peculiar to international marketing such as tariffs. In the event these
assumptions prove to be inaccurate, actual results may differ significantly from
those presently anticipated.
