    This prospectus relates to the public offering of up to 241,000 of our
common shares on behalf of the selling shareholder identified in this
prospectus.
 
    The common shares that may be offered hereby are issuable upon exercise of
warrants to purchase common shares. Each warrant entitles the holder of the
warrant to purchase one common share at an exercise price of $23.95 per share.
 
    The common shares issuable upon exercise of the warrants may be offered and
sold from time to time pursuant to this prospectus by the holder of those common
shares or by its transferees, pledgees, donees, or successors, all of which we
refer to as dealers or agents. The selling shareholder will receive all of the
net proceeds from the sale of the common shares pursuant to this prospectus,
other than the exercise price of the warrants, and will pay all underwriting
discounts and selling commissions, if any, applicable to any sale. We are
responsible for the payment of other expenses incident to the registration of
the common shares. The selling shareholder and any broker-dealers, agents or
underwriters that participate in the distribution of any common shares pursuant
to this prospectus may be deemed to be 'underwriters' within the meaning of
Section 2(11) of the Securities Act. Any discounts, commissions, concessions or
profit they earn on any sale of the common shares may be deemed to be
underwriting compensation under the Securities Act.
 
    Our common shares are quoted on the New York Stock Exchange and the Pacific
Exchange, Inc. under the symbol 'LUK.' On October 19, 2004, the closing price
for our common shares on the New York Stock Exchange was $57.10 per share.
 
    In order to protect our significant tax loss carryforwards and other tax
attributes, our certificate of incorporation contains restrictions on the
transfer of our stock and certain of our securities.

                           FORWARD-LOOKING STATEMENTS
 
    Some of the statements contained in or incorporated by reference in this
prospectus contain forward-looking statements within the meaning of the federal
securities laws. These forward-looking statements are made pursuant to the
safe-harbor provisions of the Private Securities Litigation Reform Act of 1995.
These statements may relate, but are not limited, to projections of revenues,
income or loss, capital expenditures, plans for growth and future operations,
competition and regulation, as well as assumptions relating to the foregoing.
 
    Forward-looking statements are inherently subject to risks and
uncertainties, many of which cannot be predicted or quantified. The words
'estimates,' 'expects,' 'anticipates,' 'believes,' 'plans,' 'intends' and
variations of these words and similar expressions are intended to identify
forward-looking statements that involve risks and uncertainties. Future events
and actual results could differ materially from those set forth in, contemplated
by or underlying the forward-looking statements.
 
    The factors that could cause actual results to differ materially from those
suggested by any of these statements include, but are not limited to, those
discussed or identified from time to time in our public filings, including:
 
       A WORSENING OF GENERAL ECONOMIC AND MARKET CONDITIONS OR INCREASES IN
       PREVAILING INTEREST RATE LEVELS, which may result in reduced sales of our
       products and services, lower valuations for our associated companies and
       investments or a negative impact on the credit quality of our assets;
 
       CHANGES IN FOREIGN AND DOMESTIC LAWS, REGULATIONS AND TAXES, which may
       result in higher costs and lower revenue for our businesses, including as
       a result of unfavorable political and diplomatic developments, currency
       fluctuations, changes in governmental policies, expropriation,
       nationalization, confiscation of assets and changes in legislation
       relating to non-U.S. ownership;
 
       INCREASED COMPETITION AND CHANGES IN PRICING ENVIRONMENTS, which may
       result in decreasing revenues and/or margins, increased raw materials
       costs for our plastics business, loss of market share or significant
       price erosion;
 
       CONTINUED INSTABILITY AND UNCERTAINTY IN THE TELECOMMUNICATIONS INDUSTRY,
       associated with increased competition, aggressive pricing and
       overcapacity;
 
       DEPENDENCE ON KEY PERSONNEL, in particular, our Chairman and our
       President, the loss of whom would severely affect our ability to develop
       and implement our business strategy;
 
       INABILITY TO ATTRACT AND RETAIN HIGHLY SKILLED PERSONNEL, which would
       make it difficult to conduct the businesses of certain of our
       subsidiaries, including WilTel Communications Group, Inc. and Symphony
       Health Services, LLC;
 
       ADVERSE LEGAL AND REGULATORY DEVELOPMENTS THAT MAY AFFECT PARTICULAR
       BUSINESSES, such as regulatory developments in the telecommunications and
       healthcare industries, or in the environmental area, which could affect
       our real estate development activities and telecommunications business,
       as well as our other operations;
 
       WEATHER RELATED CONDITIONS AND SIGNIFICANT NATURAL DISASTERS, INCLUDING
       HURRICANES, TORNADOES, WINDSTORMS, EARTHQUAKES AND HAILSTORMS, which may
       impact our wineries, real estate holdings and reinsurance operations;
 
       THE INABILITY TO REINSURE CERTAIN RISKS ECONOMICALLY, which could result
       in us having to self-insure business risks;
 
       CHANGES IN U.S. REAL ESTATE MARKETS, including the residential market in
       Southern California and the commercial market in Washington D.C., which
       are sensitive to mortgage interest rate levels, and the vacation market
       in Hawaii;
 
       ADVERSE ECONOMIC, POLITICAL OR ENVIRONMENTAL DEVELOPMENTS IN SPAIN, which
       could delay or preclude the issuance of permits necessary to develop our
       copper mineral rights or which could result in increased costs of
       bringing the project to completion and increased costs in financing the
       development of the project;
 
                                       ii
 

 




       THE INABILITY TO OBTAIN THE NECESSARY FINANCING FOR THE LAS CRUCES COPPER
       MINING PROJECT, which could delay or prevent completion of the project;
 
       DECREASES IN WORLD WIDE COPPER PRICES, which could adversely affect the
       commercial viability of our mineral rights in Spain;
 
       WILTEL'S DEPENDENCE ON A SMALL NUMBER OF SUPPLIERS AND HIGH-VOLUME
       CUSTOMERS (INCLUDING SBC COMMUNICATIONS INC.), the loss of any of which
       could adversely affect WilTel's ability to generate operating profits and
       positive cash flows;
 
       CHANGES IN TELECOMMUNICATIONS LAWS AND REGULATIONS, which could adversely
       affect WilTel and its customers through, for example, higher costs,
       increased competition and a loss of revenue;
 
       WILTEL'S ABILITY TO ADAPT TO TECHNOLOGICAL DEVELOPMENTS OR CONTINUED OR
       INCREASED PRICING COMPETITION IN THE TELECOMMUNICATIONS INDUSTRY, which

       positive cash flows;
 
       WILTEL'S INABILITY TO GENERATE OPERATING PROFITS AND POSITIVE CASH FLOWS,
       which could result in a default under WilTel's credit agreement, pursuant
       to which substantially all of its assets are pledged;
 
       CURRENT AND FUTURE LEGAL AND ADMINISTRATIVE CLAIMS AND PROCEEDINGS
       AGAINST WILTEL, which may result in increased costs and diversion of
       management's attention;
 
       WILTEL'S ABILITY TO ACQUIRE OR MAINTAIN RIGHTS OF WAY NECESSARY FOR THE
       OPERATION OF ITS NETWORK, which could require WilTel to find alternate
       routes or increase WilTel's costs to provide services to its customers;
 
       CHANGES IN ECONOMIC CONDITIONS INCLUDING THOSE AFFECTING REAL ESTATE AND
       OTHER COLLATERAL VALUES, the continued financial stability of our
       borrowers and their ability to make loan principal and interest payments;
 
       REGIONAL OR GENERAL INCREASES IN THE COST OF LIVING, particularly in the
       regions in which we have operations or sell our products or services,
       which may result in lower sales of such products and service; and
 
       RISKS ASSOCIATED WITH FUTURE ACQUISITIONS AND INVESTMENTS, including
       changes in the composition of our assets and liabilities through such
       acquisitions, diversion of management's attention from normal daily
       operations of the business and insufficient revenues to offset increased
       expenses associated with acquisitions.

                                    SUMMARY
 
    The following summary is qualified in its entirety by the more detailed
information included elsewhere in this prospectus. Because this is a summary, it
may not contain all of the information that may be important to you. Before
making an investment decision, you should carefully read this entire prospectus.
Unless otherwise expressly stated herein or the context otherwise requires, all
references in this prospectus to 'Leucadia,' 'we,' 'us,' 'our,' 'our company' or
'the company' refer to Leucadia National Corporation, a New York corporation and
its direct and indirect subsidiaries.
 
                                  OUR COMPANY
 
    We are a diversified holding company engaged in a variety of businesses,
including telecommunications, healthcare services, banking and lending,
manufacturing, real estate activities, winery operations, development of a
copper mine and property and casualty reinsurance. We concentrate on return on
investment and cash flow to build long-term shareholder value, rather than
emphasizing volume or market share. Additionally, we continuously evaluate the
retention and disposition of our existing operations and investigate possible
acquisitions of new businesses in order to maximize shareholder value. In
identifying possible acquisitions, we tend to seek assets and companies that are
troubled or out of favor and, as a result, are selling substantially below the
values we believe to be present.
 
    Our telecommunications operations consist of WilTel Communications Group,
Inc., which operates in two segments, Network and Vyvx. Network owns or leases
and operates a nationwide inter-city fiber-optic network providing Internet,
data, voice and video services. Vyvx transmits audio and video programming over
the network and distributes advertising media in physical and electronic form.
 
    Our healthcare services operations consists of Symphony Health Services,
LLC. Symphony is primarily engaged in the provision of physical, occupational,
speech and respiratory therapy services.
 
    Our banking and lending operations have historically consisted of making
installment loans to niche markets primarily funded by customer banking deposits
insured by the Federal Deposit Insurance Corporation. We sold substantially all
of our loan portfolio during the second quarter of 2004 and are liquidating the
remaining business in an orderly and cost efficient manner.
 
    Our manufacturing operations manufacture and market lightweight plastic
netting used for a variety of purposes including, among other things, building
and construction, erosion control, agriculture, packaging, carpet padding,
filtration and consumer products.
 
    Our domestic real estate operations include a mixture of commercial
properties, residential land development projects and other unimproved land, all
in various stages of development and all available for sale.
 
    Our winery operations consist of Pine Ridge Winery in Napa Valley,
California and Archery Summit in the Willamette Valley of Oregon. These wineries
primarily produce and sell wines in the luxury segment of the premium table wine
market.
 
    Our copper mine development operations consist of our 72.5% interest in MK
Resources Company (formerly MK Gold Company), a publicly traded company listed
on the NASD OTC Bulletin Board (Symbol: MKRR).
 
    Our property and casualty reinsurance business is conducted through our
common stock interest in Olympus Re Holdings, Ltd., a Bermuda reinsurance
company primarily engaged in the property excess, marine and aviation
reinsurance business.
                              -------------------
 
    Our principal executive offices are located at 315 Park Avenue South, New
York, New York 10010. Our telephone number is (212) 460-1900.

                                USE OF PROCEEDS
 
    In connection with the sale of any common shares offered by this prospectus,
we will receive the exercise price of $23.95 per share upon the exercise of the
related warrants. If all of the warrants pursuant to which we are registering
the common shares were exercised, we would receive an aggregate of $9,580,000
upon exercise of the warrants. The balance of the proceeds from the sale of any

Pursuant to the terms of the warrants, we are obligated to register the common

Board of Directors may deem to be relevant.
 
    In connection with the declaration of dividends or the making of
distributions on, or the purchase, redemption or other acquisition of common
shares, we are required to comply with certain restrictions contained in certain
of our debt instruments. Our regulated subsidiaries are restricted in the amount
of distributions that can be made to us without regulatory approval. For further

                        DESCRIPTION OF OUR CAPITAL STOCK
 
AUTHORIZED CAPITAL
 
    As of October 19, 2004, our amended and restated articles of incorporation
provide that we have authority to issue the following capital stock:
 
      150,000,000 common shares, $1.00 par value, of which 71,476,102 shares are
      issued and outstanding; and
 
      6,000,000 preferred shares, $1.00 par value, of which no shares are issued
      and outstanding.
 
COMMON SHARES
 
    Subject to the rights of the holders of any preferred shares that may be
outstanding, holders of our common shares are entitled to receive dividends as
may be declared by our board of directors out of funds legally available to pay
dividends, and, in the event of liquidation, dissolution or winding up of our
affairs, to share in any distribution of our assets after payment or providing
for the payment of liabilities and the liquidation preference of any outstanding
preferred shares. Each holder of common shares is entitled to one vote for each
share held of record on the applicable record date for all matters submitted to
a vote of shareholders. Holders of common shares have no cumulative voting
rights or preemptive rights to purchase or subscribe for any stock or other
securities, and there are no conversion rights or redemption, purchase,
retirement or sinking fund provisions with respect to our common shares. Our
common shares are traded on the New York Stock Exchange and the Pacific
Exchange, Inc. under the symbol 'LUK.'
 
PREFERRED SHARES
 
    We are authorized by our amended and restated certificate of incorporation
to issue up to 6,000,000 shares of preferred stock in one or more series. The
board of directors has the authority, without any vote or action by our
stockholders, to (a) authorize the issuance of preferred stock up to the limit
set by our certificate of incorporation, (b) create new series of preferred
stock and (c) fix the terms of each series, including any rights related to
dividends, voting, conversion, redemption and liquidation preference. The
issuance of preferred stock could adversely affect the voting and other rights
of holders of the common stock and may have the effect of delaying or preventing
a change in control of our company.
 
THE TRANSFER RESTRICTIONS ON OUR COMMON SHARES
 
    There are certain restrictions on the transferability of our common shares.
For a description of the transfer restrictions, see 'Transfer Restrictions on
our Common Shares' below.
 
TRANSFER AGENT
 
    American Stock Transfer & Trust Company is the Transfer Agent and Registrar
for our common shares.
 
                   TRANSFER RESTRICTIONS ON OUR COMMON SHARES
 
GENERAL
 
    In order to protect our significant tax loss carryforwards and other tax
attributes, our common shares are subject to certain transfer restrictions
contained in our certificate of incorporation. The transfer restriction imposes
restrictions on the transfer of our common shares (and any other capital stock
that we issue in the future) to designated persons.
 
TAX LAW LIMITATIONS
 
    The benefit of a company's existing tax loss and credit carryovers, as well
as the benefit of built-in losses, can be reduced or eliminated under Section
382 of the Internal Revenue Code. Section 382 limits the use of losses and other
tax benefits by a company that has undergone an 'ownership change,' as defined
in Section 382 of the Code. Generally, an 'ownership change' occurs if one or
more shareholders, each of whom owns 5% or more in value of a company's capital
stock, increase their aggregate percentage ownership by more than 50 percentage
points over the lowest percentage of stock owned by such shareholders over the
preceding three-year period. For this purpose, all holders who each own less
 
                                       3
 

 




than 5% of a company's capital stock are generally treated together as one 5%
shareholder. In addition, certain attribution rules, which generally attribute
ownership of stock to the ultimate beneficial owner thereof without regard to
ownership by nominees, trusts, corporations, partnerships or other entities, are
applied in determining the level of stock ownership of a particular shareholder.
Options (including warrants and other rights) to acquire capital stock may be
treated as if they had been exercised, on an option-by-option basis, if the
issuance, transfer or structuring of the option meets certain tests. All
percentage determinations are based on the fair market value of a company's
capital stock, including any preferred stock which is voting or convertible (or
otherwise participates in corporate growth).
 
    If an 'ownership change' were to occur in respect of Leucadia or any of its
subsidiaries or subsidiary groups, the amount of taxable income in any year (or
portion of a year) subsequent to the ownership change that could be offset by
net operating losses ('NOLs') or other tax attributes existing (or 'built-in')
prior to such 'ownership change' could not exceed an amount equal to the product
obtained by multiplying (1) the aggregate value of Leucadia, the subsidiary or
the subsidiary group that underwent the 'ownership change' by (2) the federal
long-term tax exempt rate. Because the aggregate value of Leucadia or any of its
subsidiaries, as well as the federal long-term tax-exempt rate, fluctuate, it is
impossible to predict with any accuracy the annual limitation upon the amount of
taxable income that could be offset by such NOLs or other tax attributes (and
'built-in' losses) were an 'ownership change' to occur in the future. However,
if such limitation were to exceed the taxable income against which it otherwise
would be applied for any year following an 'ownership change,' the limitation
for the ensuing year would be increased by the amount of such excess.
 
DESCRIPTION OF THE TRANSFER RESTRICTION
 
    Our certificate of incorporation generally restricts until December 31, 2024
(or earlier, in certain events) any attempted transfer of our common shares or
any other securities that would be treated as our 'stock' under the applicable
tax regulations (which we refer to herein as 'Leucadia Stock') to a person or
group of persons who own, or who would own as a result of such transfer, 5% or
more of the Leucadia Stock. The transfer restriction also restricts any other
attempted transfer of Leucadia Stock that would result in the identification of
a new '5-percent shareholder' of our company, as determined under applicable tax
regulations. This would include, among other things, an attempted acquisition of
Leucadia Stock from an existing 5-percent shareholder. For these purposes,
numerous rules of attribution, aggregation and calculation prescribed under the
Internal Revenue Code (and related regulations) will be applied in determining
whether the 5% threshold has been met and whether a group exists. The transfer
restriction may also apply to proscribe the creation or transfer of certain
'options,' which are broadly defined, in respect of the Leucadia Stock.
 
    Acquisitions of Leucadia Stock directly from us, whether by way of option
exercise or otherwise, are not subject to the transfer restriction.
Consequently, persons or entities who are able to acquire our common shares
directly from us, including our employees, officers and directors, may do so
without application of the transfer restriction, irrespective of the number of
our common shares they are acquiring. As a result, those persons or entities
dealing directly with us may be seen to receive an advantage over persons or
entitles who are not able to acquire our common shares directly from us and,
therefore, are restricted by the terms of the transfer restriction. It should be
noted, however, that any direct acquisitions of our common shares from us first
requires board approval and in granting such approval, the board will review the
implications of any such issuance for our NOLs and other tax attributes.
 
    Our board of directors has the discretion to approve a transfer of Leucadia
Stock that would otherwise violate the transfer restriction. Nonetheless, if the
board of directors decides to permit a transfer that would otherwise violate the
transfer restriction, that transfer or later transfers may result in an
'ownership change' that would limit the use of the tax attributes of Leucadia.
The board of directors intends to consider any attempted transfer individually
and determine at the time whether it is in the best interest of our company,
after consideration of any factors that the board deems relevant, to permit the
transfer notwithstanding that an 'ownership change' may occur.
 
    The transfer restriction will restrict a shareholder's ability to acquire
additional Leucadia Stock in excess of the specified limitations. Furthermore, a
shareholder's ability to dispose of his Leucadia Stock, or any other Leucadia
Stock which the shareholder may acquire, may be restricted as a result of the
transfer restriction.
 
                                       4
 

 




    Generally, the restriction is imposed only with respect to the number of
shares of Leucadia Stock, or options with respect to Leucadia Stock (the 'Excess
Stock'), purportedly transferred in excess of the threshold established in the
transfer restriction. In any event, the restriction does not prevent a valid
transfer if either the transferor or the purported transferee obtains the
approval of our board of directors.
 
    The transfer restriction restricts any person or entity, or group of persons
or entities, from acquiring sufficient Leucadia Stock to cause that person or
entity to become the owner of 5% of the Leucadia Stock, and prohibits the
current 5-percent shareholders, as determined under applicable tax regulations,
from increasing their ownership of Leucadia Stock without obtaining the approval
of our board of directors.
 
    Our certificate of incorporation further provides that all certificates
representing Leucadia Stock bear the following legend: 'THE SHARES OF STOCK
REPRESENTED HEREBY ARE SUBJECT TO RESTRICTIONS PURSUANT TO PART III OF ARTICLE
FOURTH OF THE CERTIFICATE OF INCORPORATION OF THE CORPORATION REPRINTED IN ITS
ENTIRETY ON THE BACK OF THIS CERTIFICATE.'
 
    In accordance with the transfer restriction, we will not permit any of our
employees or agents, including the transfer agent, to record any transfer of our
common shares purportedly transferred in excess of the threshold established in
the transfer restriction. As a result, requested transfers of Leucadia Stock may
be delayed or refused.
 
    Our certificate of incorporation provides that any transfer attempted in
violation of the restrictions would be void ab initio, even if the transfer has
been recorded by the transfer agent and new certificates issued. The purported
transferee of the Leucadia Stock would not be entitled to any rights of
shareholders with respect to the Excess Stock, including the right to vote the
Excess Stock, or to receive dividends or distributions in liquidation in respect
thereof, if any.
 
    If our board of directors determines that a purported transfer has violated
the transfer restriction, we will require the purported transferee to surrender
the Excess Stock, and any dividends the purported transferee has received on the
Excess Stock, to an agent designated by the board of directors. The agent will
then sell the Excess Stock in one or more arm's-length transactions, executed on
the NYSE, if possible, to a buyer or buyers, which may include us; provided that
nothing will require the agent to sell the Excess Stock within any specific time
frame if, in the agent's discretion, the sale would disrupt the market for the
Leucadia Stock or have an adverse effect on the value of the Leucadia Stock. If
the purported transferee has resold the Excess Stock before receiving our demand
to surrender the Excess Stock, the purported transferee generally will be
required to transfer to the agent the proceeds of the sale and any distributions
the purported transferee has received on the Excess Stock. From such proceeds,
the agent will pay any amounts remaining after repaying its own expenses and
reimbursing the purported transferee for the price paid for the Excess Stock (or
the fair market value of the Excess Stock at the time of the attempted transfer
to the purported transferee by gift, inheritance or similar transfer) to a named
charity or, in certain circumstances, charities selected by the Board of
Directors.
 
    The transfer restriction and related provisions contained in our amended and
restated bylaws may be deemed to have an 'anti-takeover' effect because they
restrict the ability of a person or entity, or group of persons or entities,
from accumulating in the aggregate at least 5% of the Leucadia Stock and the
ability of persons, entities or groups now owning at least 5% of the Leucadia
Stock from acquiring additional Leucadia Stock. The transfer restriction
discourages or prohibits accumulations of substantial blocks of shares for which
shareholders might receive a premium above market value.
 
    Notwithstanding the restrictions, however, there remains a risk that certain
changes in relationships among shareholders or other events will cause a change
of ownership to occur under Section 382 of the Internal Revenue Code. Further,
there can be no assurance, in the event transfers in violation of the transfer
restriction are attempted, that the IRS will not assert that those transfers
have federal income tax significance notwithstanding the transfer restriction.
As a result, the transfer restriction serves to reduce, but not necessarily
eliminate, the risk that Section 382 will cause the limitations described above
on the use of tax attributes of Leucadia.
 
    We have been advised by our counsel, Weil, Gotshal & Manges LLP, that,
absent a court determination, (1) there can be no assurance that the transfer
restriction will be enforceable against all of our shareholders and (2) the
transfer restriction may be subject to challenge on equitable grounds.
 
                                       5
 

 




However, it should be noted that the existing transfer restriction has been in
place since December 31, 1992 and has not been challenged to date.
 
    The determination of 5% shareholder status is based upon the outstanding
Leucadia Stock, which currently consists of only common shares. Consequently, in
determining the existence of a 5% shareholder, a holder's percentage ownership,
taking into account certain rules of attribution, would be calculated with
reference to outstanding common shares (increased, for such holder, by the
number of common shares deemed to be, but not actually outstanding). Future
changes in the capitalization of Leucadia may affect who will be deemed a 5%
shareholder, thereby affecting the applicability of the transfer restriction to
future transfers of common shares. However, because the transfer restriction
generally applies (with certain exceptions) to a person or group of persons who
owns (including by attribution) at least 5% of all 'stock' of Leucadia, a change
in capitalization that increases the 'stock' of Leucadia likely would result in
a reduction in the number of individuals or groups who would be subject to the
transfer restriction, while a diminution of 'stock' of Leucadia would have the
opposite effect.
 
    Holders are advised to carefully monitor their ownership of common shares
(and any future securities of Leucadia that may constitute 'Leucadia Stock' for
purposes of the transfer restriction) and should consult their own legal
advisors and/or Leucadia to determine whether their ownership approaches the
prohibited level.

         CERTAIN MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
                          TO NON-UNITED STATES HOLDERS
 
    The following summary describes certain material U.S. federal income and, to
a limited extent, certain U.S. federal estate tax consequences relating to the
purchase, ownership and disposition of the common shares applicable to non-U.S.
holders, as defined below. This summary is based on the Internal Revenue Code of
1986, or the Code, and Treasury regulations promulgated thereunder,
administrative pronouncements and judicial decisions, changes to any of which
subsequent to the date of this prospectus may affect the tax consequences
described herein. We undertake no obligation to update this tax summary in the
future. This summary applies only to non-U.S. holders that will hold the common
shares as capital assets within the meaning of Section 1221 of the Code. This
summary does not purport to be a complete analysis of all the potential tax
consequences that may be material to a non-U.S. holder based on his or her
particular tax situation. For example, this summary does not address tax
consequences applicable to non-U.S. holders that may be subject to special tax
rules, such as 'controlled foreign corporations,' 'passive foreign investment
companies,' 'foreign personal holding companies,' certain former citizens and
long-term residents of the United States or corporations that accumulate
earnings to avoid U.S. federal income tax. Such persons should consult with
their own tax advisors to determine the U.S. federal tax consequences that may
be relevant to them. This discussion does not address the tax treatment of
partnerships or persons who hold their interests through partnerships or other
pass-through entities. If you are a partner in a partnership holding our common
shares, you should consult your tax advisor regarding the tax consequences of
the ownership and disposition of our common shares. This discussion does not
consider the effect of any applicable state, local, foreign or other tax laws,
including gift tax laws.
 
    When we refer to a non-U.S. holder, we mean a beneficial owner of common
shares that for U.S. federal income tax purposes is other than:
 
      a citizen or individual resident of the United States, as determined for
      U.S. federal income tax purposes;
 
      a corporation, or other entity taxable as a corporation for U.S. federal
      income tax purposes, created or organized in or under the laws of the
      United States or any state thereof or the District of Columbia;
 
      an estate the income of which is subject to U.S. federal income taxation
      regardless of its source; or
 
      a trust that is subject to the primary supervision of a U.S. court and one
      or more U.S. persons have the authority to control all substantial
      decisions of the trust, or that has a valid election in effect under
      applicable Treasury regulations to be treated as a U.S. person.
 
TAXATION OF DISTRIBUTIONS AND DISPOSITIONS
 
    DISTRIBUTIONS ON COMMON SHARES
 
    Generally, dividends paid to a non-U.S. holder will be subject to U.S.
withholding tax at a 30% rate, subject to the two following exceptions:
 
      Dividends effectively connected with a trade or business of a non-U.S.
      holder within the United States generally will not be subject to
      withholding if the non-U.S. holder provides a properly executed IRS
      Form W-8ECI (or other successor form) and otherwise complies with
      applicable IRS certification requirements and generally will be subject to
      U.S. federal income tax on a net income basis at regular rates. In the
      case of a non-U.S. holder that is a corporation, such effectively
      connected income also may be subject to the branch profits tax at a 30%
      rate (or such lower rate as may be prescribed by an applicable tax
      treaty).
 
      The withholding tax might not apply, or might apply at a reduced rate,
      under the terms of an applicable tax treaty. Under Treasury regulations,
      to obtain a reduced rate of withholding under a tax treaty, a non-U.S.
      holder generally will be required to provide a properly executed IRS
      Form W-8BEN (or other successor form) and otherwise satisfy the applicable
      certification and other requirements. A non-U.S. holder of common shares
      eligible for a reduced rate of U.S. withholding
 
                                       7
 

 




      tax may obtain a refund of any excess amounts withheld by filing an
      appropriate claim for refund with the Internal Revenue Service, or the
      IRS.
 
    DISPOSITIONS OF COMMON SHARES
 
    Generally, a non-U.S. holder will not be subject to U.S. federal income tax
with respect to gain recognized upon the disposition of such holder's shares of
common shares unless:
 
      the non-U.S. holder is an individual who is present in the United States
      for 183 days or more in the taxable year of disposition and certain other
      conditions are met;
 
      such gain is effectively connected with the conduct by the non-U.S. holder
      of a trade or business within the United States or, if a tax treaty
      applies, the gain is effectively connected with the conduct by the
      non-U.S. holder of a trade or business within the United States and is
      attributable to a U.S. permanent establishment (or a fixed base in the
      case of an individual) maintained by the non-U.S. holder; or
 
      we are or have been a 'U.S. real property holding corporation' for U.S.
      federal income tax purposes and, assuming that our common shares are
      deemed to be 'regularly traded on an established securities market,' the
      non-U.S. holder held, directly or indirectly, at any time during the
      five-year period ending on the date of disposition or such shorter period
      that such shares were held, more than five percent of our common shares.
 
    An individual non-U.S. holder described in the first bullet point above will
be subject to a flat 30% tax on the gain derived from the sale, which may be
offset against U.S. source capital losses (even though the individual is not
considered a resident of the United States). A non-U.S. holder described in the
second bullet point above will be subject to tax on the gain derived from the
sale under regular graduated U.S. federal income tax rates and, if it is a
corporation, may be subject to the branch profits tax at a rate equal to 30% (or
such lower rate as may be prescribed by an applicable treaty). We do not believe
we currently are, and we do not currently anticipate becoming, a 'U.S. real
property holding corporation' for U.S. federal income tax purposes. As of the
date of this offering, our common shares will be regularly traded on an
established securities market.
 
FEDERAL ESTATE TAXES
 
    Common shares owned or treated as owned by an individual who is a non-U.S.
holder (as specifically defined for U.S. federal estate tax purposes) at the
time of death will be included in the individual's gross estate for U.S. federal
estate tax purposes and may be subject to U.S. federal estate tax, unless an
applicable estate tax treaty provides otherwise.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
    INFORMATION REPORTING
 
    We must report annually to the IRS and to each non-U.S. holder the entire
amount of any dividend that is paid to such holder. Copies of the information
returns reporting such distributions and withholding may also be made available
to the tax authorities in the country in which the non-U.S. holder resides under
the provisions of an applicable income tax treaty.
 
    The payment of proceeds from the sale of common shares by a broker to a
non-U.S. holder is generally not subject to information reporting if:
 
      the beneficial owner of the common shares certifies its non-U.S. status
      under penalties of perjury, or otherwise establishes an exemption; or
 
      the sale of the common shares is effected outside the United States by a
      foreign office, unless the broker is:
 
          a U.S. person or U.S. related person as defined in the Code; or
 
          a controlled foreign corporation for U.S. federal income tax purposes.
 
                                       8
 

 




    BACKUP WITHHOLDING
 
    Dividends paid to a non-U.S. holder of common shares generally will be
exempt from backup withholding if the non-U.S. holder provides a properly
executed IRS Form W-8BEN or otherwise establishes an exemption. The payment of
proceeds from a disposition of common shares effected by a non-U.S. holder
outside the United States by or through a foreign office of a broker generally
will not be subject to backup withholding. Payment of the proceeds from a
disposition by a non-U.S. holder of common shares made by or through the U.S.
office of a broker is generally not subject to backup withholding if the
non-U.S. holder provides a properly executed IRS Form W-8BEN or otherwise
establishes an exemption. Notwithstanding the foregoing, backup withholding may
apply if either we, our paying agent or the broker has actual knowledge, or
reason to know, that the non-U.S. holder is a U.S. person.
 
    Backup withholding is not an additional tax. Any amount withheld from a
payment to a non-U.S. holder under these rules will be allowed as a credit
against such holder's U.S. federal income tax liability and may entitle such
holder to a refund, provided that the required information is furnished timely
to the IRS.
 
    THE U.S. FEDERAL INCOME AND ESTATE TAX DISCUSSION SET FORTH ABOVE IS
INCLUDED FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A
HOLDER'S PARTICULAR SITUATION. POTENTIAL INVESTORS SHOULD CONSULT THEIR OWN TAX
ADVISORS WITH RESPECT TO THE TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP
AND DISPOSITION OF THE COMMON SHARES, INCLUDING THE TAX CONSEQUENCES UNDER U.S.
FEDERAL, STATE, LOCAL, FOREIGN AND OTHER TAX LAWS, INCLUDING GIFT AND ESTATE TAX
LAWS, AND THE POSSIBLE EFFECTS OF CHANGES IN FEDERAL OR OTHER TAX LAWS.

                              SELLING SHAREHOLDER
 
    On October 4, 2000, following shareholder approval, we issued to each of Ian
M. Cumming and Joseph S. Steinberg, our Chairman and President, respectively,
warrants to purchase 241,000 common shares at an exercise price of $23.95 per
share, 105% of the closing price of a common share, as reported on the New York
Stock Exchange Composite Tape, on May 16, 2000, the date of the Board of
Directors' resolution authorizing the issuance of the warrants. On
September 24, 2004, the selling shareholder purchased warrants to purchase
241,000 common shares from Mr. Cumming.
 
    The selling shareholder and its affiliates from time to time have provided
in the past and may provide future commercial or investment banking and
financial advisory services to us and our affiliates in the ordinary course of
business, for which they have received or will receive customary compensation.
In addition, the selling shareholder and its affiliates have engaged in the past
and may engage in the future in securities transactions with us and our
affiliates on an arms'-length basis. We have an equity interest in Jefferies
Partners Opportunity Fund II, LLC, a registered broker-dealer managed and
controlled by the selling shareholder. For further information, see our Annual
Report on Form 10-K for the fiscal year ended December 31, 2003 incorporated by
reference into this prospectus.
 
    The following table sets forth certain information concerning the number of
common shares that may be offered from time to time under this prospectus by the
selling shareholder named in the table. We prepared this table based on the
information supplied to us by the selling shareholder and we have not sought to
verify such information. The selling shareholder is a registered broker-dealer.
The selling shareholder acquired the warrant for investment purposes, and not as
compensation for underwriting activities. The selling shareholder may be
considered to be an underwriter, within the meaning of the Securities Act, with
respect to any common shares that it sells pursuant to this prospectus.
 
    The percentages of common shares beneficially owned and being offered are
based on the number of our common shares that were outstanding as of October 19,
2004. Because the selling shareholder may offer all or some portion of the
common shares pursuant to this prospectus, we have assumed for purposes of the
table below that the selling shareholder will sell all of the common shares
offered by this prospectus pursuant to this prospectus. As of October 19, 2004,
we had 71,476,102 common shares outstanding.
 
    To prevent dilution to the selling shareholder, pursuant to Rule 416 under
the Securities Act, the numbers in the table below may change if additional
common shares become issuable upon exercises of the warrants to prevent dilution
resulting from stock splits, stock dividends or similar events involving our
common shares. The number of common shares beneficially owned by the selling
shareholder is determined under rules promulgated by the SEC, and it is not
necessarily indicative of beneficial ownership for any other purpose.
 
    The selling shareholder has not held any position or office or has had any
material relationship with us within the past three years, except as otherwise
described above:

(a)  Includes common shares issuable upon exercise of warrants.

(b)  Based on 71,476,102 common shares outstanding as of
     October 19, 2004 plus the 241,000 common shares issuable
     upon exercise of the warrants held by the selling
     shareholder and 15,166 common shares issuable upon
     conversion of our 3 3/4% Convertible Senior Subordinated
     Notes due 2014 currently held by the selling shareholder.

(c)  We do not know when or in what amounts the selling
     shareholder may offer for sale common shares pursuant to
     this offering. The selling shareholder may sell the common
     shares covered by this prospectus from time to time, and may
     also decide not to sell any or all of the common shares it
     is allowed to sell under this prospectus. Because the
     selling shareholder may offer all or some of the common
     shares pursuant to this offering, we cannot estimate the
     number of common shares that the selling shareholder will
     hold after completion of the offering. For purposes of this
     table, we have assumed that the selling shareholder will
     have sold all of the common shares covered by this
     prospectus upon the completion of the offering.

                              PLAN OF DISTRIBUTION
 
    The selling shareholder, which term includes all transferees, pledges,
donees or their successors, may from time to time sell the common shares covered
by this prospectus, directly to purchasers or offer the common shares through
underwriters, broker-dealers or agents, who may receive compensation in the form
of underwriting discounts, concessions or commissions from the selling
shareholder and/or the purchasers of common shares for whom they may act as
agent, which discounts, concessions or commissions as to any particular
underwriter, broker-dealer or agent may be in excess of those customary in the
types of transactions involved.
 
    The common shares may be sold in one or more transactions:
 
       at fixed prices;
 
       at prevailing market prices at the time of sale;
 
       at varying prices determined at the time of sale; or
 
       at negotiated prices.
 
    The sales may be effected in transactions that may involve crosses or block
transactions, in the following manner:
 
      on any national securities exchange or quotations service on which the
      common shares may be listed or quoted at the time of sale, including the
      New York Stock Exchange;
 
       in the over-the-counter-market;
 
      in transactions otherwise than on these exchanges or services or in the
      over-the-counter market; or
 
      through the writing and exercise of options, whether these options are
      listed on any options exchange or otherwise.
 
    In connection with the sale of the common shares, the selling shareholder
may enter into hedging transactions with broker-dealers or other financial
institutions, which may in turn engage in short sales of the common shares in
the course of hedging position they assume. The selling shareholder may sell the
common shares short and deliver common shares to close out short positions, or
loan or pledge the common shares to broker-dealers that in turn may sell these
common shares.
 
    Our outstanding common shares are listed for trading on the New York Stock
Exchange and the Pacific Exchange, Inc. under the symbol 'LUK.'
 
    In order to comply with the securites laws of some jurisidicitons, if
applicable, the holders of common shares may offer and sell those common shares
in such jurisdictions only through registered or licensed brokers or dealers. In
addition, under certain circumstances, in some jurisdictions the common shares
may not be offered or sold unless they have been registered or qualified for
sale in the applicable jurisdiction or an exemption from registration or
qualification requirements is available and is complied with.
 
    The selling shareholder and any underwriters, broker-dealers or agents that
participate in the sale of the common shares, may be 'underwriters' within the
meaning of Section 2(11) of the Securities Act. Any discounts, commissions,
concessions or profit they earn on any sale of the common shares may be
underwriting compensation under the Securities Act. The selling shareholder has
acknowledged that it understands its obligations to comply with the provisions
of the Exchange Act and the rules thereunder relating to stock manipulation,
particularly Regulation M, and have agreed that it will not engage in any
transaction in violation of such provisions.
 
    If required, at the time of a particular offering of common shares by the
selling shareholder, a supplement to this prospectus will be circulated setting
forth the name or names of any underwriters, broker-dealers or agents, any
discounts, commissions or other terms constituting compensation for underwriters
and any discounts, commissions or concessions allowed or reallowed or paid to
agents or broker-dealers.
 
    The warrants obligate us to register the common shares issuable upon
exercise of the warrants, under applicable federal and state securities laws
under specific circumstances and at specific times. The warrants provide for
cross indemnification of the selling shareholder and us and our respective
directors, officers
 
                                       12
 

 




and controlling persons against specific liabilities in connection with the
offer and sale of the common shares, including liabilities under the Securities
Act. In the event the selling shareholder sells its common shares through any
underwriter, the warrants provide for indemnification by us of those
underwriters and their respective directors, officers and controlling persons
against specified liabilities in connection with the offer and sale of those
common shares. Pursuant to the warrants, we will bear all fees and expenses
incurred in connection with the registration of the common shares, except that
selling shareholder will pay all broker's commissions and, in connection with
any underwritten offering, underwriting discounts and commissions.
 
    We are required by the terms of the warrants to file any amendments and
supplements to this prospectus and the registration statement of which this
prospectus is a part as may be necessary to keep the registration statement
effective for the shorter of 30 days or the completion of the distribution and
to comply with the provisions of the Securities Act with respect to the
disposition of the common shares covered by the registration statement in
accordance with the selling shareholders intended method of distribution.
 
                                 LEGAL MATTERS
 
    Weil, Gotshal & Manges LLP has passed upon the validity of the common shares
on behalf of us. Members of Weil, Gotshal & Manges LLP beneficially own, in the
aggregate, approximately 108,000 common shares, representing less than 0.1% of
the outstanding common shares.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    The registrant is a New York corporation. Sections 722 through 725 of the
New York Business Corporation Law (the 'Business Corporation Law') provide that
a corporation may indemnify, with certain limitations and exceptions, a director
or officer as follows: (1) in a derivative action, against his reasonable
expenses, including attorneys' fees but excluding certain settlement costs,
actually and necessarily incurred by him in connection with the defense thereof,
or an appeal therein, if such director or officer acted, in good faith, for a
purpose which he reasonably believed to be in (or in the case of service for
another corporation, not opposed to) the best interests of the corporation; and
(2) in a civil or criminal non-derivative action or proceeding including a
derivative action by another corporation, partnership or other enterprise in
which any director or officer of the indemnifying corporation served in any
capacity at the indemnifying corporation's request, against judgments, fines,
settlement payments and reasonable expenses, including attorneys' fees, incurred
as a result thereof, or any appeal therein, if such director or officer acted in
good faith, for a purpose which he reasonably believed to be in (or, in the case
of service for any other corporation, not opposed to) the best interests of the
corporation and, in criminal actions and proceedings, in addition, had no
reasonable cause to believe that his conduct was unlawful. Such indemnification
is a matter of right where the director or officer has been successful on the
merits or otherwise, and otherwise may be granted upon corporate authorization
or court award as provided in the statute.
 
    Section 721 of the Business Corporation Law provides that indemnification
arrangements can be established for directors and officers, by contrast, by-law,
charter provision, action of shareholders or board of directors, on terms other
than those specifically provided by Article 7 of the Business Corporation Law,
provided that no indemnification may be made to or on behalf of any director or
officer if a judgment or other final adjudication adverse to the director or
officer establishes that his acts were committed in bad faith or were the result
of active and deliberate dishonesty and were material to the cause of action so
adjudicated, or that he personally gained in fact a financial profit or other
advantage to which he was not legally entitled. Article V of the Company's
By-Laws provides for the indemnification, to the full extent authorized by law,
of any person made or threatened to be made a party in any civil or criminal
action or proceeding by reason of the fact that he, his testator or intestate is
or was a director or officer of the Company.
 
    Section 726 of the Business Corporation Law provides that a corporation may
obtain insurance to indemnify itself and its directors and officers. The Company
maintains an insurance policy providing both directors and officers liability
coverage and corporate reimbursement coverage.
 
    Article Sixth of the Company's Certificate of Incorporation contains a
charter provision eliminating or limiting director liability for monetary
damages arising from breaches of fiduciary duty, subject only to certain
limitations imposed by statute.

ITEM 17. UNDERTAKINGS.
 
    The undersigned registrant hereby undertakes:
 
        1: To file, during any period in which offers or sales are being made, a
    post-effective amendment to this registration statement:
 
           a. To include any prospectus required by Section 10(a)(3) of the
       Securities Act of 1933;
 
           b. To reflect in the prospectus any facts or events arising after the
       effective date of the registration statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       the registration statement. Notwithstanding the foregoing, any increase
       or decrease in volume of securities offered (if the total dollar value of
       securities offered would not exceed that which was registered) and any
       deviation from the low or high end of the estimated maximum offering
       range may be reflected in the form of prospectus filed with the
       Commission pursuant to Rule 424(b) if, in the aggregate, the changes in
       volume and price represent no more than a 20 percent change in the
       maximum aggregate offering price set forth in the 'Calculation of
       Registration Fee' table in the effective registration statement;
 
           c. To include any material information with respect to the plan of
       distribution not previously disclosed in the registration statement or
       any material change to such information in the registration statement;
 
provided, however, that clauses (a) and (b) do not apply if the information
required to be included in a post-effective amendment by such clauses is
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange
Act of 1934 that are incorporated by reference in the registration statement;
 
        2. That, for the purpose of determining any liability under the
    Securities Act of 1933, each such post-effective amendment shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.
 
                                      II-2
 

 




        3. To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.
 
    Each undersigned registrant hereby undertakes that, for purposes of
determining any liability under
the Securities Act of 1933, each filing of the registrant's annual report
pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of
1934 that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of each
registrant pursuant to the foregoing provisions or otherwise, each registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by each registrant of expenses incurred
or paid by a director, officer or controlling person of such registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, each registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
 
    The undersigned registrant hereby undertakes that:
 
        1. For purposes of determining any liability under the Securities Act of
    1933, the information omitted from the form of prospectus filed as part of
    this registration statement in reliance on Rule 430A and contained in a form
    of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
    497(h) under the Securities Act shall be deemed to be part of this
    registration statement as of the time it was declared effective;
 
        2. For purposes of determining any liability under the Securities Act of
    1933, each post-effective amendment that contains a form of prospectus shall
    be deemed to be a new registration statement relating to the securities
    offered therein, and the offering of such securities at that time shall be
    deemed to be the initial bona fide offering thereof;
 
    The undersigned registrant hereby undertakes to file an application for the
purpose of determining the eligibility of the trustee to act under subsection
(a) of section 310 of the Trust Indenture Act ('Act') in accordance with the
rules and regulations prescribed by the Commission under section 305(b)(2) of
the Act.
