Dear Mr. Spirgel:

Reference is made to your letter of October 27, 2006 (the "October 27, 2006
Letter"). On behalf of Leucadia National Corporation ("Leucadia"), set forth
below is each numbered paragraph of the October 27, 2006 Letter followed by the
response of Leucadia to each comment contained in the October 27, 2006 Letter.
The number of each response corresponds to the number of the comment in your
letter.


Form 10-K for the Fiscal Year Ended December 31, 2005
- -----------------------------------------------------

1.    We understand that you plan to amend your Form 10-K to comply with our
      prior comments 1, 2 and 3. Please note our further comments below.

              Please see our responses below.

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

2.    Please refer to our comments 1 and 2. Tell us why you consider certain
      non-current investments to be "readily available" to meet your liquidity
      needs. Include in your response what you mean by "readily available."
      Also, tell us the reason for the separate liquidity discussion of you and
      your parent.

            Non-current investments are considered "readily available" if they
            are publicly traded securities and are not pledged as collateral or
            held by subsidiaries that are party to agreements which restrict the
            Company's ability to convert the investments into cash and deploy
            the cash for any purpose. Such non-current investments are
            considered available to meet liquidity needs because the Company
            believes it has the ability to convert the investments into cash in
            a timely, orderly manner and at a value not materially different
            from the aggregate carrying value on the balance sheet. The Company
            believes its definition of liquidity is consistent with Instruction
            5 of Item 303(a) of Regulation S-K, and is important for readers of
            the Company's financial statements to understand that it has the
            ability to spend significant amounts on new acquisitions and
            investments without having to incur the time and expense involved
            with raising capital from other sources.

            The business of the Company is the acquisition, management and
            operation of disparate businesses and investments and, if the
            Company considers it appropriate, the disposition of those
            businesses or investments. Usually, acquisitions do not complement
            existing operations, and often are in completely new industry
            sectors. The Parent Company is the holding company for these
            businesses and investments, and it is not unusual for the components
            of the Company's continuing operations to change dramatically from
            one year to the next. The purpose of the Parent Company Liquidity
            discussion is to identify the funds available to make acquisitions
            and investments, to report on changes in the make up of the
            Company's operations and investments during the period, to report on
            changes in the Parent's outstanding debt and equity securities
            during the period, and to report on any other event that is material
            to the Parent Company's liquidity. The Company believes that the
            Parent Company Liquidity discussion is important to understanding
            how quickly its underlying operations and investments have changed
            and could change.

            The purpose of the discussion in Consolidated Liquidity is
            principally to explain the more significant changes and components
            in the consolidated statement of cash flows, which was expanded in
            the Form 10-K/A filed with the Commission on November 3, 2006, and
            to discuss long-term debt obligations at the Company's subsidiaries.

3.    We note that the Level 3 common stock is subject to a transfer restriction
      that limits the number of shares the Company can sell on any given day
      until May 22, 2006. However, we note that you sold all the shares during
      the first quarter of 2006. Please tell us when and how the restrictions
      were removed.

            As disclosed on page 30, there were certain exceptions to the
            transfer restriction, and one of these exceptions included certain
            block trades. The Level 3 shares were sold pursuant to a permissible
            block trade during the first quarter of 2006, so there was no need
            to have any restriction removed. In the Form 10-K/A filed with the
            Commission on November 3, 2006, the Company has disclosed that
            certain block trades are not subject to the transfer restriction.

4.    Refer to your response to prior comments 3, 4 and 5.

      o     It is unclear to us how a "decrease in the size of the Company's
            trading portfolio" impacted your cash flows since all related notes
            to the financial statements on pages F-22 and F-32 indicate that it
            is not material. Please advise or revise.

      o     Please tell us why the increased cash flow was due to the plastics
            manufacturing segment's "increased revenues" instead of operating
            income.

      o     Please separately caption proceeds from the SBC funding of WilTel's
            investing activities.

      o     In 2005, you attributed the reduction of long-term debt to a
            "repayment of $442,500 of debt of operations sold." We note that the
            2004 balance of non-current liabilities of discontinued operations
            was $669 million. Please tell us where the balance of the
            non-current liabilities is reflected in the statement of cash flows.

                  During 2004, the Company increased its investment in its
                  trading portfolio through its investment in INTL, an
                  investment which is disclosed in footnote 3 on page F-14. This
                  new investment accounts for substantially all of the use of
                  funds for investments classified as trading, net as reflected
                  on the consolidated statement of cash flows for the year ended
                  December 31, 2004. During 2005, the Company's net investment
                  in its trading portfolio (net of liabilities for short
                  positions) declined, even though the Company did not
                  experience material realized or unrealized losses. This
                  resulted from the sales of investments classified as trading.

                  Increased revenues at the plastics manufacturing segment were
                  the most significant reason for its increased operating
                  income. In the Form 10-K/A filed with the Commission on
                  November 3, 2006, the Company has revised the disclosure to
                  comply with this comment.

                  The proceeds from SBC's funding of WilTel's investing
                  activities were $25,000,000. In the Form 10-K/A filed with the
                  Commission on November 3, 2006, the Company has revised the
                  disclosure to comply with this comment.

                  As of the closing date of the sale of WilTel, the balance of
                  non-current liabilities of discontinued operations that
                  remained with WilTel were acquired by the buyer pursuant to
                  the stock purchase agreement. The transfer of these
                  liabilities did not result in a use of cash; therefore, as a
                  non-cash transaction, it is not directly reflected in the
                  statement of cash flows. The transfer of these liabilities is
                  a component of the gain on disposal and therefore is included
                  in net income; however, the entire gain on disposal was
                  deducted from net income to arrive at net cash provided by
                  operating activities.

Consolidated Balance Sheets, page F-3
- -------------------------------------

5.    Please refer to prior comment 6. Please confirm to us that the inventory
      costs included in your cost of sales are not material. Otherwise, disclose
      your accounting policy for inventories.

                  Although the book value of manufacturing inventories has not
                  been material to current assets as of the balance sheet dates,
                  the inventory component of cost of sales is significant in
                  relation to cost of sales. Manufacturing inventories are
                  stated at the lower of cost or market, with cost determined
                  under the first-in-first-out method. The Company will disclose
                  its inventory accounting policy in its Annual Report on Form
                  10-K for the year ended December 31, 2006.

Note 5. Discontinued Operations, page F-19
- ------------------------------------------

6.    Please refer to prior comments 8 and 9. Based on your textual disclosures,
      it is unclear to us how you calculated the gain from discontinued
      operations which was material to your income statement. As required in
      paragraph 47(a) of SFAS 144, and further explained in paragraph B119,
      please separately present the carrying amount of the major classes of
      assets and liabilities included as part of a disposal group in the
      financial statements that cover the period in which it is sold and
      disclose the related proceeds and/or consideration. Additionally, please
      disclose parenthetically the related income taxes attributed to the income
      and gain from discontinued operations.

                  With respect to WilTel, the second paragraph of footnote 5 on
                  page F-19 identifies and quantifies all of the components of
                  the gain except for the net book value of the assets sold and
                  expenses, which can be calculated from the information
                  presented. As of the closing date, the net book value of the
                  WilTel assets sold plus expenses aggregated $689,300,000. The
                  other component of the 2005 gain on disposal of discontinued
                  operations relates to the sale of the Waikiki Beach hotel,
                  which is disclosed in footnote 5 on page F-20. With respect to
                  the Waikiki Beach hotel, the selling price, net cash received
                  at closing and the gain are disclosed; the net book value of
                  the assets sold can be calculated from the information
                  presented. As of the closing date, the book value of the
                  Waikiki Beach assets sold plus expenses aggregated
                  $38,500,000. The Company believes that its disclosure of the
                  components of the gain on disposal of discontinued operations
                  and the related proceeds and/or consideration is adequate.

                  The Company did not have any assets or liabilities on its 2005
                  balance sheet that were classified as held for sale or
                  discontinued operations. With respect to WilTel, the Company
                  reclassified its 2004 balance sheet to deconsolidate WilTel's
                  balance sheet accounts into four categories that are reflected
                  directly on the face of the consolidated balance sheet,
                  current and non-currents assets and liabilities. The Company
                  disclosed the reclassification and its reason for doing so in
                  footnote 1 on page F-9. As previously discussed in response to
                  prior comment 8, the Company believes that the assets and
                  liabilities of the Waikiki Beach hotel are not material as of
                  December 31, 2004 and that no additional disclosure is needed.

                  The Company did consider the requirements of paragraph 47(a)
                  of FAS 144 as further explained in paragraph B119. The Company
                  deconsolidated WilTel's balance sheet as of December 31, 2004
                  because WilTel's balance sheet accounts were material to the
                  Company, and absent a deconsolidation a meaningful comparison
                  of the Company's 2005 and 2004 balance sheets would not have
                  been possible. However, since WilTel was sold prior to
                  December 31, 2005, the Company does not believe a further
                  breakdown of these four asset categories as of December 31,
                  2004 was material or meaningful. The Company also notes that
                  since WilTel was never classified as an asset held for sale,
                  the importance of segregating assets measured on different
                  methods of accounting referred to in paragraph B119 is not
                  applicable. The Company believes that its disclosure of the
                  December 31, 2004 assets and liabilities of discontinued
                  operations is adequate.

                  Income taxes related to income from discontinued operations is
                  disclosed in footnote 5 on page F-21 and are not material for
                  any period. Income taxes related to gain on disposal of
                  discontinued operations are zero for 2005 and not material for
                  other periods. Please see the response to comment 9 below for
                  a discussion of the related income taxes attributed to the

                  income and gain from discontinued operations for 2005. In
                  future filings with the Commission, the Company will
                  parenthetically disclose the after-tax gains related to
                  discontinued operations immediately next to its disclosure of
                  pre-tax gains.

7.    Please refer to prior comments 11 and 12.

      o     It is unclear to us how the WilTel facility was accounted for in the
            balance sheet. If it is currently for sale, tell us why it is not
            reported separately as an asset held for sale. Refer to paragraphs
            30 and 46 of FAS 144.

      o     Tell us your consideration of paragraphs 30(e) and B76 of FAS 144 in
            determining the carrying amount of the WilTel facility.

                  As disclosed in footnote 5 on page F-19, the WilTel
                  headquarters facility is classified with other assets in the
                  Company's consolidated balance sheet, along with its other
                  real estate investments. As disclosed in footnote 5 on page
                  F-20, the Company believes it will take at least two years
                  before the facility can be sold; accordingly the Company
                  concluded that the WilTel facility did not meet the criteria
                  specified in paragraph 30(d) of FAS 144 for held for sale
                  classification (expectation for a completed sale within one
                  year). In addition, had the facility met the criteria for held
                  for sale classification, the carrying amount is not material
                  to non-current assets or total assets.

                  Since the facility does not meet all of the criteria specified
                  in paragraph 30(d) of FAS 144 for held for sale
                  classification, the Company did not consider paragraphs 30(e)
                  and B76 of FAS 144 in determining the carrying amount of the
                  facility. The Company used the expected present value
                  technique referenced in paragraph 23 of FAS 144 to determine
                  the fair value of the facility. In making that determination,
                  the Company developed multiple cash flow scenarios reflecting
                  a range of possible selling prices, including the current
                  asking price of $80,000,000.

Note 7. Trade, Notes and Other Receivables, Net, page F-26
- ----------------------------------------------------------

8.    Please refer to prior comment 15. Tell us why it is appropriate to present
      the $236 million settlement in continuing operations. Also, please confirm
      to us that the revenues from SBC's minimum purchase commitment are
      included in discontinued operations. If not, tell us why it is appropriate
      to present these revenues in continuing operations.

                  The revenues from SBC's minimum purchase commitment are
                  included in discontinued operations. The income resulting from
                  the $236,000,000 SBC settlement is also included in
                  discontinued operations, for the reasons disclosed in our

                  response to prior comment 15. The December 31, 2005 balance of
                  the SBC receivable that was not yet paid ($198,500,000) is
                  classified as an asset of continuing operations since it is
                  payable to WilTel's immediate parent company, was not an asset
                  purchased by Level 3 and is not an asset held for sale.

Note 16. Income Taxes, page F-34
- --------------------------------

9.    Refer to your disclosure in the Form 10-Q for the fiscal quarter ended
      June 30, 2005 in which you stated that your estimate of future taxable
      income . . . "incorporated the assumptions used by WilTel for its
      impairment analysis (updated for the new SBC agreements). . . If the
      Company realizes . . . its ability to generate future taxable income
      necessary to realize a portion of the deferred tax asset is materially
      reduced, additions to the valuation allowance could be recorded."

      o     Considering that a significant portion of your tax projections
            appeared to have been premised on income streams from WilTel, please
            tell us if your conclusions changed following the sale of WilTel and
            whether additional valuation allowances were warranted as of the
            2005 balance sheet date and the interim periods thereafter. If not,
            tell us why.

      o     If you utilized some portion of your deferred tax asset in 2005 to
            offset taxable income arising from WilTel's SBC arrangements, tell
            us why you did not allocate some portion of the tax benefit (from
            the reversal of the valuation allowance) towards income from
            discontinued operations.

                  The Company did not change its conclusions about its ability
                  to realize the deferred tax asset as of the 2005 balance sheet
                  date or during subsequent interim periods. After the sale of
                  WilTel closed, WilTel's future taxable income that was
                  included in the Company's taxable income projections was
                  removed from its consolidated taxable income estimate;
                  however, such future amounts were offset by other changes in
                  projected taxable income, including the projected taxable
                  income expected to be generated from investment of the sales
                  proceeds received from Level 3. At December 31, 2005 and at
                  subsequent interim balance sheet dates, the Company has
                  assessed the differences between its actual and expected
                  earnings and changes in its operations in order to determine
                  if the magnitude of future taxable income had materially
                  changed. To date the Company's projection of future taxable
                  income has not materially changed.

                  The Company did allocate a portion of the reversal of the
                  valuation allowance to income from discontinued operations in
                  2005, in an amount equal to the tax provision that would have
                  been charged to discontinued operations had there been no
                  reversal of the valuation allowance. This resulted in the

10.   Please refer to prior comment 27. Tell us the nature and significant terms
      of the underlying insurance contracts for which you pay variable insurance
      premiums as they relate to the WilTel defined benefit pension plan. Refer
      to paragraphs 5 and 7 of SFAS 88.

                  There are no insurance contracts that the Company or the
                  defined benefit pension plan has entered into. The variable
                  insurance premiums referred to in the response to prior
                  comment 27 are variable insurance premiums charged by the
                  Pension Benefit Guaranty Corporation to certain employee
                  benefit plans. Generally, the more underfunded a plan is the
                  higher the charge from this government agency. The Company's
                  Quarterly Report on Form 10-Q for the period ended September
                  30, 2006 will describe these premiums as government charged
                  variable insurance premiums.
