Exhibit 99.1

2.       We have the following comments regarding the presentation of your
non-GAAP measures
         adjusted net income and adjusted earnings per share:
             Please present a reconciliation of the differences between the
non-GAAP financial
             measures with the most directly comparable GAAP financial measures
as required by
             Item 10(e)(1)(B) of Regulation S-K. The reconciliations should
present income taxes
             as a separate adjustment and your disclosure should clearly
explain how the tax
             effects of non-GAAP adjustments are calculated, in accordance with
Question 102.11
             of the Division of Corporation Finance   s Compliance and
Disclosure Interpretations
             on Non-GAAP Financial Measures; and
             Please explain to us how you determined the adjustments for (1)
additional
             performance-based companywide special compensation awarded to all
non-
             executive, eligible team members in recognition of your annual
performance and (2)
             costs associated with construction and startup of your Texas Flat
Roll Steel Mill are
             appropriate based on the guidance in Question 100.01 of the
Division of Corporation
             Finance   s Compliance & Disclosure Interpretations on Non-GAAP
Financial
             Measures, or tell us how you plan to revise your non-GAAP
financial measures in
             future filings.
3.       We note that your reconciliation of net loss to EBITDA includes a
reconciling item related
         to noncontrolling interest. Please be advised that Question 103.01 of
the Division of
         Corporation Finance   s Compliance and Disclosure Interpretations on
Non-GAAP
         Financial Measures indicates that EBITDA is defined as    earnings
before interest, taxes,
         depreciation and amortization.    Please revise the non-GAAP measure
you present as
         EBITDA to only include adjustments for items contemplated by its
acronym or revise the
         title of the non-GAAP measure you present to convey the additional
adjustment.
4.       Please describe to us the nature of the specific costs included in the
non-GAAP
         adjustments related to unrealized (gains) losses and inventory
valuation you presented in
         your Adjusted EBITDA reconciliation. In addition, please explain how
you determined
         that these adjustments are appropriate based on the guidance in
Question 100.01 of the
         Division of Corporation Finance   s Compliance & Disclosure
Interpretations on Non-
         GAAP Financial Measures.
