                CALIFORNIA STEEL INDUSTRIES, INC. AND SUBSIDIARY

              Notes To Consolidated Condensed Financial Statements

1. Basis of Presentation

   The accompanying unaudited consolidated condensed financial statements of
California Steel Industries, Inc. and its subsidiary as of and for the three
and six months ended June 30, 1999 and 1998 have been prepared in accordance
with generally accepted accounting principles for interim financial information
and the rules and regulations of the Securities and Exchange Commission.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
However, the information reflects all adjustments (consisting only of normal
recurring adjustments) that, in the opinion of management, are necessary to
present fairly the financial position and results of operations for the periods
indicated.

   The accompanying consolidated condensed financial statements should be read
in conjunction with the audited consolidated financial statements and notes
thereto for the years ending December 31, 1998 and 1997 contained in California
Steel Industries, Inc.'s Amendment No. 2 to Registration Statement on Form S-4
(File number 333-79587) filed with the Securities and Exchange Commission on
September 23, 1999.

2. New Accounting Pronouncements

   In June 1998, the Financial Accounts Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS 133"). SFAS 133 establishes accounting and
reporting standards for derivative instruments, including derivative
instruments embedded in other contracts, and hedging activities. SFAS 133 is
effective for all fiscal quarters of fiscal years beginning after June 15,
2000. Application of this accounting standard is not expected to have a
material impact on our financial position, results of operations or liquidity.

3. Inventories

   Inventories are stated at the lower of cost (determined under the last-in,
first-out method of accounting) or market value.

4. Long-Term Debt

   On April 6, 1999, we issued an aggregate of $150,000,000 of ten-year 8.5%
senior unsecured notes. Interest is payable on the notes on April 1 and October
1, commencing October 1, 1999. The notes are senior in right of payment to all
of our subordinated indebtedness and equal in right of payment to all of our
existing and future indebtedness that is not by its terms subordinated to the
notes. We may redeem the notes at any time after April 1, 2004. The indenture
governing the notes contains covenants that limit our ability to incur
additional indebtedness, pay dividends on, redeem or repurchase capital stock
and make investments, create liens, sell assets, sell capital stock of certain
of our subsidiaries, engage in transactions with affiliates and consolidate,
merge or transfer all or substantially all of our assets and the assets of
certain of our subsidiaries on a consolidated basis.

   Proceeds from the notes were used to permanently repay outstanding bank debt
under a $10,000,000 term loan provided by The Dai-Ichi Kangyo Bank,
Netherlands, and a $50,000,000 revolving credit facility and a $80,000,000 term
loan, both provided by a syndicate of institutions led by the Industrial Bank
of Japan, Ltd., Los Angeles Agency.

5. Dividend Payments

   The Company's board of directors approved and declared a dividend in the
amount of $8,631,000 for common and preferred stockholders. On April 30, 1999,
$6,848,000 was paid to holders of preferred stock and $1,783,000 to common
stockholders.

</TABLE>

   Net sales. Net sales for the second quarter of 1999 decreased by
$10,295,000, or 5.7%, compared to the second quarter of 1998. On a year to date
basis net sales decreased by $25,476,000, or 7.1%, from $356,734,000 for the
six months ended June 30, 1998 to $331,258,000 for the six months ended June
30, 1999. The decrease is attributable to period to period reductions in the
average selling price of our products due to the lingering effects of import
surges throughout 1998. Reduced sales prices in both the second quarter and six
months ending June 30, 1999 reduced net sales by approximately $31,900,000 and
approximately $64,900,000 when compared to the corresponding periods in 1998.
The effects of decreasing sales prices have been offset by higher sales volumes
and a better product mix emphasizing higher value added galvanized steel. 1999
volume is higher when compared to 1998 on both a quarter to quarter basis as
well as a year to date basis. By selling more volume, we increased both second
quarter and year to date 1999 net sales by approximately $15,700,000 and
approximately $28,400,000, respectively. In addition, by selling more
galvanized products as a percentage of total products sold we increased both
second quarter and year to date 1999 net sales by approximately $5,900,000 and
approximately $11,000,000, respectively. We have recently experienced slight
sales price increases on hot rolled products and expect this trend to continue
for the balance of the year.

   Gross profit. For the second quarter of 1999, gross profit increased by
$12,638,000, or 57.8%, compared to second quarter 1998 and by $17,674,000, or
40.8%, from $43,371,000 for the six months ended June 30, 1998 to $61,045,000
for the six months ended June 30, 1999. Gross profit as a percentage of net
sales increased from 12.1% for the second quarter of 1998 to 20.3% for the same
period in 1999 and from 12.2% for the six months ended June 30, 1998 to 18.4%
for the same period in 1999. Our gross profit increased as a result of (i) our
slab costs decreasing at a faster rate than our unit sales prices, (ii) a
product mix that included more of the higher value added galvanized products
and (iii) higher sales volumes. Additionally, during the second quarter of
1999, we recorded a $3,500,000 LIFO inventory adjustment reflecting an increase
in inventory value versus a $769,000 LIFO adjustment during the same period in
1998 reflecting a decrease in inventory value. For the first six months in
1999, we recorded a $10,638,000 LIFO adjustment versus a $3,169,000 LIFO
adjustment in the same period in 1998, as a result of lower inventory costs. If
we had used the FIFO method of accounting

                                       7
<PAGE>

instead, gross profit as a percentage of net sales would have increased to
12.5% and decreased to 18.2% for the second quarters of 1998 and 1999,
respectively. Gross profit as a percentage of net sales would have decreased to
11.3% for the six-month period ended June 30, 1998 and 15.2% for the six-month
period ended June 30, 1999.

   Selling, general and administrative expenses. Selling, general and
administrative expenses increased $449,000 from $7,313,000 in the second
quarter of 1998 to $7,762,000 in the second quarter of 1999 and increased
slightly from $14,592,000 for the first six months of 1998 compared to
$15,083,000 for the same period in 1999. This increase resulted from a variety
of miscellaneous expenses, the majority of which consisted of an increase in
profit sharing accrual due to higher profits and an increase in shipping
expenses as a result of higher volumes.

   Equity in income (loss) of affiliate. During the second quarter of 1999, we
recognized $88,000 of equity earnings from our investment in Companhia
Siderurgica de Tubarao, which consists of our pro-rata share of Companhia
Siderurgica de Tubarao's loss, which amounted to $512,000 based on our 1.5%
ownership interest offset by $600,000 of amortized negative goodwill. Our
investment in Companhia Siderurgica de Tubarao is accounted for under the
equity method of accounting. Companhia Siderurgica de Tubarao is a publicly-
traded Brazilian company engaged in the production of steel slab. Approximately
95% of Companhia Siderurgica de Tubarao's products are exported outside of
Brazil and sold predominately in U.S. dollars. This high percentage of U.S.
dollar denominated cash flow tends to lessen the impact of market risks related
to fluctuations in currency exchange rates.

   Interest expense. For the second quarter of 1999 our interest expense
decreased by $106,000 compared to the second quarter of 1998. Interest expense
decreased $259,000, or 3.1%, from $8,345,000 for the first six months in 1998,
to $8,086,000 for the same period in 1999. The decrease in interest expense
resulted from a slight decrease in our average outstanding debt during the
first six months of 1999 compared to the first six months of 1998. Interest
expense figures are net of interest income and capitalized interest of $324,000
for the three months and $529,000 for the six months ended June 30, 1999 and
$581,000 for three months and $946,000 for the six months ended June 30, 1998.

   Income taxes. Income taxes increased $6,815,000 from $9,043,000 for the six
month period ended June 30, 1998 to $15,858,000 for the six month period ending
June 30, 1999. Income taxes increased as a result of higher income before tax.

   Net income. Net income for the three and six month periods ended June
30,1999 was $13,665,000 and $22,819,000, respectively as compared to $6,705,000
and $12,986,000 for the three and six month periods ended June 30, 1998, for
period to period increases of 103.8% and 75.7%, respectively.

Liquidity and Capital Resources

   At June 30, 1999, we had $10,807,000 in cash and cash equivalents and
$38,000,000 available under our credit facility. During the six months ended
June 30, 1999, cash flows from operations generated $49,982,000, which
consisted of $22,819,000 in net income, $12,285,000 in depreciation and
amortization expense and a net cash flow increase of $14,878,000 due to changes
in assets and liabilities, the majority of which were a $18,010,000 decrease in
inventories, a $7,551,000 increase in accounts receivables and a $10,624,000
increase in income taxes payable. Cash flows from investing activities during
the six months ended June 30, 1999 consisted predominately of $18,827,000 of
capital expenditures. Cash flows from financing activities during the six
months ended June 30, 1999 consisted of net repayments under both short-term
and long-term lines of credit and a dividend payment of $8,631,000.

   At June 30, 1999, we had approximately $4,100,000 in material commitments
for capital investments. We estimate 1999 total capital expenditures to be
approximately $45,000,000.

   On April 6, 1999, we issued an aggregate of $150,000,000 of ten-year 8.5%
senior unsecured notes. Interest is payable on the notes on April 1 and October
1, commencing October 1, 1999. The notes are senior in right of payment to all
of our subordinated indebtedness and equal in right of payment to all of our
existing

                                       8
<PAGE>

and future indebtedness that is not by its terms subordinated to the notes. We
may redeem the notes at any time after April 1, 2004. The indenture governing
the notes contains covenants that limit our ability to incur additional
indebtedness, pay dividends, redeem or repurchase capital stock and make
investments, create liens, sell assets, sell capital stock of certain of our
subsidiaries, engage in transactions with affiliates and consolidate, merge or
transfer all or substantially all of our assets and the assets of certain of
our subsidiaries on a consolidated basis.

   Proceeds from the notes were used to permanently repay outstanding bank debt
under a $10,000,000 term loan provided by The Dai-Ichi Kangyo Bank,
Netherlands, a $50,000,000 revolving credit facility and a $80,000,000 term
loan, both provided by a syndicate of institutions led by the Industrial Bank
of Japan, Ltd., Los Angeles Agency.

   We anticipate that our primary liquidity requirements will be for working
capital, capital expenditures, debt service and the payment of dividends. We
believe that cash generated from operations and available borrowings under our
bank facility will be sufficient to enable us to meet our liquidity
requirements for fiscal 1999.

Year 2000

   The Year 2000 problem is the result of computer programs being written using
two digits rather than four digits to define the applicable year. In 1997, we
began to examine our business for Year 2000 compliance. The results of our
analysis and status of our Year 2000 compliance are summarized below.

Information and Non-Information Technology Systems

   Our significant non-information technology systems include water, electric,
telephones, sewer and waste-water discharge systems. Our engineering department
is currently analyzing all of the non-information technology systems that
support our business to determine the extent to which they are Year 2000
compliant and to develop contingency plans, as necessary, to deal with any Year
2000 problems. We expect this assessment, repair and the development of any
related contingency plans, to be completed by September 30, 1999. To date,
testing has not revealed year 2000 exposure in our non-information technology
systems.

   We have three information technology systems which help us run our business,
including an administrative system, a production control system and a process
control system. In the two years since we began to examine our systems for Year
2000 compliance, we have developed a comprehensive program to address potential
Year 2000 problems with our information technology systems. This program
includes three phases: assessment, remediation and testing.

   Assessment--This phase entails a comprehensive assessment of each of our
information technology systems with respect to Year 2000 problems. Based on
testing we have undertaken since 1997, we have concluded that each of our three
information systems utilizes some date sensitive data. Our administrative
system includes our accounting, human resources, purchasing, sales and shipping
functions. Diagnostic testing by a third party vendor revealed that the
accounting, human resources and purchasing functions were purchased from an
outside vendor and were not Year 2000 compliant. The other parts of our
administrative system were developed by us and our tests revealed that they are
Year 2000 compliant. Testing conducted in 1998 revealed that our production
control system, which was developed in-house and which is used to schedule
production at our mills and to manage production data as it relates to sales
order entry, is Year 2000 compliant. Our process control system, which is a
computer system that runs the production lines at each of our mills, was tested
in 1998 and 1999 and the testing revealed that two pieces of production
equipment have minor Year 2000 problems.

   Remediation--This phase involves reprogramming or replacing our systems that
are exposed to Year 2000 problems. We have purchased a Year 2000 compliant
software system known as an enterprise resource planning (ERP) system. We
purchased the ERP system to replace the portions of our administrative system
that are not

                                       9
<PAGE>

Year 2000 compliant and to modernize several aspects of our non-production
systems technology. We have also developed remedial measures for the two pieces
of production equipment that we identified as having minor Year 2000 exposure.
We expect that we will complete remediation efforts on these two pieces of
equipment prior to October 1999.

   Testing--This phase involves testing the effects of our remediation efforts.
During June 1999, we implemented and tested the accounting, human resources and
purchasing modules of the ERP system and found that they are fully operational
and Year 2000 compliant. We expect to test the Year 2000 compliance of the two
pieces of equipment that are part of our process control system prior to
October when we expect our remediation efforts to be complete.

Year 2000 Costs

   As of June 30, 1999, we have incurred approximately $1,500,000 in costs
related to implementing the ERP system. We currently estimate that complete
implementation of the ERP system will cost approximately $1,950,000 and these
costs will be capitalized to the extent permitted under generally accepted
accounting principles. We expect that we will incur the $450,000 balance of the
cost related to this project in the third quarter of 1999. We expect to incur
an additional $200,000 in the third quarter of 1999 to make our process control
system Year 2000 compliant.

Third Party Relationships

   Our material third party relationships are with slab suppliers, including
foreign suppliers. We have contacted our three largest suppliers and they have
confirmed to us that they are all Year 2000 compliant. We are also in the
process of acquiring data to determine the preparedness of our other slab
suppliers and we expect to complete this analysis by the end of the third
quarter of 1999.

   We have also sent surveys to the vendors from which we made 85% of our 1998
purchases to determine their preparedness for the Year 2000. Of the 104 surveys
we sent, we have received 72 responses. These responses are currently being
evaluated to determine whether and the extent to which these suppliers are
Year 2000 compliant. We also expect to complete this analysis by the end of the
third quarter of 1999.

   We have not contacted our customers to assess their Year 2000 compliance and
we do not intend to do so. Because no single customer represents more than ten
percent of our total sales, we do not anticipate material problems with any
potential Year 2000 exposure our customers might have. Our sales to foreign
customers amount to less than one percent of our total sales, therefore, we are
not exposed to material risks from foreign customers' potential Year 2000
problems.

   We have not independently verified or validated the accuracy of third
parties' assessments of their Year 2000 risk and cost estimates.

Worst Case Scenario and Contingency Plan

   We believe we have taken and continue to take all prudent steps to identify
and remediate our Year 2000 exposure and that we have an effective program in
place to address any Year 2000 problems in a timely manner. Our expectations
regarding our Year 2000 efforts, however, are subject to various uncertainties
that could cause actual results to differ from those discussed here. Those
uncertainties include our success in identifying systems that are not Year 2000
compliant and the success of vendors, suppliers, customers and other third
parties with which we interact in addressing any Year 2000 problems they might
have. We believe that our most reasonable worst case scenario is that there
could be some interruptions in deliveries from our third party vendors and
possibly in our interactions with customers, to the extent that they have their
own Year 2000 problems.


                                       10
<PAGE>

   We have not developed a specific contingency plan to deal with the Year 2000
problem because, in the ordinary course of business, we maintain a general
contingency plan for emergencies. In this regard, each of our departments is
responsible for ensuring that they have back-up capabilities to eliminate or
minimize the negative effects of emergencies. In addition, we maintain
inventories capable of supporting sales activities for approximately sixty days
with an additional thirty days of inventory in transit to our facilities at any
given time. We will consider developing a more specific contingency plan as we
complete assessment of our non-information systems and our third party exposure
over the next few months.

                           PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

   We are from time to time in the ordinary course of business, subject of
various pending or threatened legal actions. We believe that any ultimate
liability arising from pending or threatened legal actions should not have a
material adverse effect on our financial condition. On September 30, 1998, we
joined 11 major domestic steel producers in filing a Petition for the
Imposition of Antidumping Duties and Countervailing Duties pursuant to Section
701, 702, 731 and 732(b) of the tariff Act of 1930, as amended, before the
International Trade Commission of the U.S. Department of Commerce (the "DOC")
and the U.S. International Trade Commission ("USITC") (Case Nos. C-351-826, A-
588-846, A-821-809 and A-351-828) in the matter of certain hot rolled carbon
steel flat products from Japan, Brazil, and the Russian Federation. At issue is
whether Japan, Brazil and Russia committed unfair and anti-competitive trade
practices in relation to their export of hot rolled band products into the
United States. As a result of this petition the USITC voted to impose anti-
dumping duties ranging from 17% to 67%. Additionally, agreements have been
concluded between the U.S. government and the governments of Brazil and Russia
to limit hot rolled shipments into the United states for a period of five years
in exchange for the United States suspending tariffs and ending its
investigation into whether Brazilian and Russian carbon hot-rolled steel has
been subsidized.

   Under this determination Kawasaki Steel Corporation, the parent of one of
our stockholders, is subject to the 67% anti-dumping duty on any hot rolled
steel products it exports to the United States. We do not believe that this
will cause Kawasaki Steel Corporation to raise the prices of the steel slab it
sells to us because Kawasaki Steel Corporation sells a variety of other steel
products, both within and outside the United States. In addition, the
determination does not prevent Kawasaki Steel Corporation from selling hot
rolled steel in any other part of the world. Furthermore, we have not purchased
any hot-rolled steel products from Kawasaki Steel Corporation this year and do
not intend to unless the prices Kawasaki Steel Corporation charges are
competitive. We do not plan on violating covenants in our credit agreements by
purchasing products at higher prices from Kawasaki which would occur if we were
to purchase such products. Companhia Vale do Rio Doce is not affected by this
determination because it was not a party to the petition as it does not produce
or sell steel products.
