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

1998 vs. 1997: Net sales in 1998 declined 7% from 1997 levels primarily due to 
reduced pricing across all steel and tubular product lines, lower volume in 
the specialty semi-finished and galvanized steel lines and lower snowplow and 
tubular product shipments. Sales volume for Armco's higher margin specialty 
flat-rolled steels increased 9%, somewhat offsetting these declines. 

Operating profit increased 2% despite lower sales, reflecting increased volume 
of higher margin steel products, lower operating costs, lower pension and 
retiree medical benefit expenses, and a one-time gain of $7.1 from a 
settlement with a vendor. Postretirement employee benefit expenses in 1998 
were again lower as a result of prior years' favorable investment returns on 
pension plan assets and lower than expected increases in medical benefit 
costs.

The change in sundry other - net between 1997 and 1998 is primarily the result 
of pension income and lower medical expenses in 1998 related to retirement 
benefits for former employees of Armco facilities that have been shut down or 
divested. The pension income resulted from favorable investment returns on 
pension plan assets related to the former facilities, and lower medical 
expenses were due to lower than expected benefit cost increases. Income of 
$24.2 in 1998 and expense of $2.0 in 1997 was included in sundry other - net 
for these benefits. Sundry other - net in 1998 also included an additional 
gain of $1.1 for the vendor settlement mentioned previously. In 1997, sundry 
other - net included a $4.0 gain for the settlement of certain partially 
impaired long-term receivables. 

In 1998, income from continuing operations included $4.3 for the favorable 
settlement of certain state tax issues.

In 1997, Armco recorded $2.7 of income from discontinued operations for a tax 
refund related to a previously divested company. 

Also in 1997, Armco recorded a $3.0 extraordinary loss upon the early 
retirement of debt, which was refinanced by a senior note offering.

Effective January 1, 1998, Armco changed its method of accounting for 
unrecognized net gains and losses related to its obligations for pensions and 
other postretirement benefits. Armco recognized income of $237.5, or $2.20 per 
share of common stock ($1.88 per diluted share), for the cumulative effect of 
this accounting change. Under the newly adopted method, Armco recognizes into 
income, as a fourth quarter adjustment, any unrecognized net gains and losses 
that exceed 10% of the larger of the benefit obligations or plan assets, and 
amortizes amounts inside this 10% corridor over the average remaining service 
life of active participants (approximately 15 years). Adoption of the new 
method increased 1998 income from continuing operations by $3.0 or $0.03 per 
share of common stock.

Favorable returns on pension plan assets and lower than expected medical cost 
increases have contributed to continuing lower expense in sundry other - net.


1997 vs. 1996: Armco's 1997 net sales increased 6% over 1996 primarily as a 
result of higher shipments of specialty steels and tubular products. Partially 
offsetting the higher shipments of specialty steel products was a decline in 
prices across the stainless and electrical steel product lines, primarily due 
to intense global competition.

Operating profit increased 41% in 1997 primarily as a result of lower costs in 
the manufacturing operations, the consolidation of Greens Port Industrial 
Park, which in the prior year was an investment held for sale, and lower 
employee benefit expenses. Benefit expenses were lower as a result of 
favorable investment returns on pension plan assets and lower than expected 
increases in medical benefit costs.

Included in the 1996 operating profit were special charges totaling $8.8 for a 
loss on the sale of Armco's nonresidential construction

business and a decision to exit a line of light truck equipment manufactured 
by Douglas Dynamics, LLC, Armco's snowplow and ice control products 
manufacturer. Operating profit in 1996 also included nonrecurring income of 
$8.6 from claim settlements, including a business interruption insurance 
claim. 

Sundry other - net expense decreased in 1997 as a result of lower expenses 
related to long-term benefit obligations for former employees of Armco 
facilities that have been shut down or divested. Included in sundry other - 
net for 1996 was the recognition of $6.3 of gains in connection with asset 
sales at Greens Port.

Income from discontinued operations consisted of additional gains of $2.7 in 
1997 and $6.5 in 1996 for tax refunds related to a previously divested 
company. 

Outlook for 1999: Armco expects modest volume increases in the Specialty Flat-
Rolled Steels segment. Assuming a favorable outcome in the stainless flat-
rolled steel trade cases filed with the U.S. Department of Commerce and the 
International Trade Commission in 1998, Armco expects stainless sheet and 
strip pricing to stabilize and possibly improve in the latter half of 1999. 
Overall results for the Specialty Flat-Rolled Steels segment are expected to 
be negatively affected by higher retiree benefit expenses, primarily due to 
lower expected returns on pension plan assets.

Results for the other segments are expected to improve somewhat in 1999 
compared to 1998.

Armco is shipping more value-added specialty steels to the automotive and 
industrial markets.

1998 vs. 1997: Net sales for the Specialty Flat-Rolled Steels segment 
decreased 5% in 1998 primarily as a result of lower pricing in all product 
lines and reduced shipments in specialty semi-finished and galvanized steels. 
Record import levels continued to depress pricing across most stainless and 
electrical steel product lines.

Specialty flat-rolled steel volume increased 9% on the strength of record 
shipments of automotive exhaust stainless and the highest electrical steel 
shipments in almost 20 years. Automotive exhaust stainless demand was driven 
by high levels of North American vehicle production, while electrical steel 
sales were stimulated by strong housing starts and demand for electrical 
machinery and equipment. However, lower prices, particularly for stainless 
sheet and strip products, reduced average sales per ton in this product line 
by 6%.

Specialty semi-finished shipments and average sales per ton decreased by 26% 
and 17%, respectively, reflecting worldwide market softness, excess capacity 
and increased imports.

Galvanized carbon steel shipments, produced by the Dover Operations from 
purchased steel coils, decreased 20% due to increased competition and low-
priced imports.

Income from continuing operations in 1998 increased $14.4 over 1997, primarily 
as a result of increased sales of higher margin automotive exhaust stainless 
and electrical steels, lower operating and raw material costs, a $7.1 gain 
from a settlement with a vendor, and reduced pension and other retiree benefit 
expenses. In addition, increased efficiencies and higher yields were made 
possible by a number of cost reduction and productivity improvement 
initiatives. These improvements were partially offset by the continuing 
deterioration in selling prices.

1997 vs. 1996: Net sales in 1997 were 5% higher than in 1996 on an 8% increase 
in tons shipped. A decrease in the segment's overall average sales per ton 
resulted from increased shipments of lower priced specialty semi-finished 
steels, partially offset by a change in the mix of carbon steel shipments from 
hot bands to higher priced galvanized steel products. 

A 3% reduction in average sales per ton of specialty flat-rolled products 
reflected increased import competition on certain grades of chrome nickel 
stainless and cold rolled non-oriented electrical steels and elimination of 
most of the remaining surcharges on stainless steel. Armco and other specialty 
steel producers add raw material surcharges to the price of their product to 
compensate for higher costs incurred when the price of key raw materials such 
as nickel, chromium or molybdenum rises above certain levels. Such surcharges 
were minimal in 1997 and the second half of 1996.

Specialty semi-finished shipments increased substantially in 1997 over 1996, 
primarily as a result of increased sales of chrome nickel hot bands. However, 
average sales per ton declined 14%, reflecting worldwide overcapacity.

                                                  Armco 1998 Annual Report  17

Shipments of galvanized carbon steel increased in 1997, but the increased tons 
were offset by the elimination of carbon hot band shipments. In the first half 
of 1996, Armco exited the lower priced hot band market, shifting to higher 
priced galvanized steel products and thus increasing average sales per ton by 
14% in the year-to-year comparison.

Specialty Flat-Rolled Steels' 1996 income from continuing operations included 
an $8.6 credit from various claim settlements, including a business 
interruption insurance claim. Excluding the claim settlements, income 
increased in 1997 primarily as a result of lower costs due to facilities 
upgrades, more stable operating conditions and lower employee benefit 
expenses. Costs in 1996 were adversely affected by several planned outages, 
including outages necessary to upgrade Armco's finishing facilities as part of 
the strategic facilities plan. The outages and the subsequent process of 
restarting and returning these facilities to full capability contributed to 
higher costs and lower yields. To meet demand during this period, Armco 
substantially increased its use of outside processors to finish some of its 
stainless steels, resulting in higher costs.

Outlook for 1999: Armco anticipates stable volume and further cost reductions 
for most product lines during the next twelve months. Although automotive 
exhaust stainless shipments are expected to remain strong, supported by North 
American vehicle sales, tons shipped may decline slightly from 1998's record 
level. Stable housing starts are expected to continue to stimulate demand for 
oriented electrical steels, while high levels of lower priced imports continue 
to adversely affect non-oriented electrical steel product sales. 

In recent years, record levels of imports have depressed pricing on specialty 
steel products in the U.S. In June 1998, Armco and other domestic producers of 
flat-rolled stainless sheet and strip products filed petitions with the U.S. 
Department of Commerce and the International Trade Commission charging eight 
foreign countries with violations of U.S. trade laws. A finding that unfairly 
traded imports have caused injury to domestic producers could result in 
tariffs that may help slow the flood of imports. On July 24, 1998, the 
International Trade Commission issued its preliminary finding that there has 
been injury to domestic producers. On November 10, 1998, the U.S. Department 
of Commerce announced preliminary results in the subsidy investigations, 
establishing countervailing duty rates for companies in France, Italy and 
South Korea. On December 17, 1998, a preliminary determination on antidumping 
margins was announced by the U.S. Department of Commerce for companies in 
those three countries, as well as in Germany, Japan, Mexico, Taiwan and the 
United Kingdom. Final antidumping determinations are expected to be announced 
in the second quarter of 1999. 

In addition, with respect to electrical steels, in mid-1999 the U.S. 
Department of Commerce and the International Trade Commission are expected to 
review existing antidumping and countervailing duties involving Italian and 
Japanese producers to determine whether these protections should be extended 
for another five years. The failure to obtain or extend meaningful tariff 
protections for any of the products Armco sells could adversely affect prices 
and reduce profitability.

Assuming a favorable outcome in the stainless sheet and strip trade cases, 
Armco expects prices for these products to stabilize in the first half of 1999 
and show some improvement in the latter half of the year. Prices for certain 
electrical and semi-finished steels, however, are expected to be lower than in 
1998.

Overall results for the Specialty Flat-Rolled Steels segment are expected to 
be negatively affected by higher retiree benefit expenses, primarily due to 
lower expected returns on pension plan assets.

The Tubular Products business segment represents the results of Sawhill 
Tubular, a manufacturer of steel pipe and tubing. Sawhill has plants in Sharon 
and Wheatland, Pennsylvania and Warren, Ohio.

1998 vs. 1997: Net sales decreased on lower volume and selling prices, which 
reflected a general oversupply in the market, including a high level of 
imported pipe, and market softness in certain products. Although some cost 
savings were achieved in 1998, income decreased as a direct result of lower 
sales and margins.

1997 vs. 1996: Net sales increased 10% in 1997 primarily due to higher 
shipments along most major product lines, as well as modest price increases. 
Sawhill's income improved in 1997, driven by higher volume and lower operating 
costs.

Outlook for 1999: Sawhill Tubular's sales and profitability are expected to 
remain flat with slight volume increases, offset by increasing pressure on 
pricing from excess capacity and imported pipe.

Armco has been, and continues to be, in negotiations for the sale of Sawhill 
Tubular. However, no assurance can be given that a sale will be completed.

The Other Businesses segment includes the results of Douglas Dynamics, LLC, a 
manufacturer of snowplows and ice control products, with plants in Milwaukee, 
Wisconsin, Rockland, Maine and Johnson City, Tennessee; and Greens Port 
Industrial Park, which leases land, buildings and rail car storage facilities 
and operates a deep water loading dock on the Houston Ship Channel. 

1998 vs. 1997: Although light truck sales were strong, lower net sales 
reflected significantly below average snowfall during the 1997/1998 winter in 
Douglas Dynamics' major markets, resulting in lower income from continuing 
operations. Greens Port's results improved during 1998 as all phases of its 
business posted increases in revenues and profits over last year.

1997 vs. 1996: The segment's income from continuing operations, excluding the 
special charge, improved 38% in 1997, due to manufacturing efficiencies 
achieved during the year at Douglas Dynamics and reduced operating expenses 
following the decision in 1996 to exit certain unprofitable product lines. In 
1996, a $2.9 special charge was recorded in this segment primarily for the 
writedown of assets and severance costs related to the decision to discontinue 
a line of light truck equipment manufactured by Douglas Dynamics. In addition, 
1997 results increased with the consolidation of Greens Port, which in the 
prior year was an investment held for sale.

Outlook for 1999: Douglas Dynamics' 1999 sales will depend on the level of 
four-wheel drive light truck sales and total snowfalls in its major markets. 
Based on early snowfalls, snowplow shipments are expected to be somewhat 
higher in 1999. Greens Port's results are expected to continue to improve due 
to recent facility expansions.

DISCONTINUED OPERATIONS
Aerospace and Strategic Materials
Armco sold its Aerospace and Strategic Materials business segment in 1985. 
Pursuant to the sales agreement, Armco retained the benefit of its share of 
any net proceeds of certain tax refund claims for periods prior to the sale. 
In 1996, Armco received a federal tax refund and recorded a $6.5 increase to 
its gain on the sale of the segment. In 1997, Armco recognized another $2.7 
gain for state and federal tax refunds.

Armco Financial Services Group (AFSG)
Armco's investment in AFSG represents the net assets of its discontinued 
insurance and finance leasing businesses, which have been largely liquidated. 
The insurance companies, including Northwestern National Insurance Company 
(NNIC), have stopped writing new business and are being "run off." These 
insurance companies have not written any new business for retention since 1986 
except for an immaterial amount of guaranteed renewable accident and health 
business.

In March 1997, North Atlantic Insurance Company, a group of international 
insurance companies previously affiliated with AFSG but sold in 1991, filed an 
application for voluntary liquidation in the United Kingdom. As a result of 
this voluntary liquidation filing, certain claims have been asserted against 
NNIC by insureds of North Atlantic. NNIC is defending these claims as well as 
pursuing related claims against third parties and North Atlantic.

Liquidity and Financial Resources: AFSG is accounted for as a discontinued 
operation under the liquidation basis of accounting, whereby future cash 
inflows and outflows are considered. AFSG believes the existing invested 
assets, related future income and other assets it owns will provide sufficient 
funds to meet all future claims payments and other liabilities. 

The loss reserves, net of reinsurance recoverables and future investment 
income, decreased to $59.9 at December 31, 1998 from $88.1 at December 31, 
1997. AFSG estimates that 60% of the claims will be paid in the next five 
years and that substantially all of the claims will be paid by the year 2017. 
The ultimate amount of the claims as well as the timing of claims payments are 
estimated based on an annual review of loss reserves performed by independent 
and consulting actuaries.

Outlook: Armco management continues to believe, based on current facts and 
circumstances and the opinions of outside counsel and advisors, that future 
charges, if any, resulting from the liquidation of AFSG, including matters 
related to the voluntary liquidation of North Atlantic, will not be material 
to Armco's financial condition or liquidity. However, it is possible that, due 
to fluctuations in Armco's operating results, future developments could have a 
material effect on the results of one or more future interim or annual 
periods.

In January 1999, Armco redeemed the remaining $111 million of a senior note 
issue. Armco has no major debt due until 2007.


LIQUIDITY AND CAPITAL RESOURCES
At December 31, 1998, Armco had $270.8 of cash, cash equivalents and short-
term liquid investments, compared to $194.9 at December 31, 1997. Cash, cash 
equivalents and short-term liquid investments increased $75.9 during 1998, 
primarily as a result of $95.2 of cash generated by operations and $74.4 from 
the issuance of new 8-7/8% 10-year Senior Notes in December. Major cash 
payments during the year included $32.6 of capital expenditures, $51.2 for 
debt retirement and $17.7 for preferred stock dividends. 

The net proceeds of the new debt issue, along with other existing cash 
balances, were used to retire Armco's 9-3/8% Senior Notes due 2000 on January 
14, 1999. Holders of the 9-3/8% Senior Notes were notified on December 15, 
1998 of Armco's intention to redeem this issue. At December 31, 1998, $111.0 
of these notes were outstanding, all of which were retired, resulting in the 
recognition of an extraordinary loss of $2.8 in the first quarter of 1999. 
Armco has no other material debt payments due until the year 2007.

                                                  Armco 1998 Annual Report  19

At December 31, 1998, Armco had in place two bank credit facilities, totaling 
$170.0. In 1998, the terms of these facilities were extended and both will 
expire in 2001. 

Under a receivables facility, Armco sells substantially all its trade 
receivables to a wholly owned subsidiary, Armco Funding Corporation (AFC). In 
1998, AFC and its bank group amended its revolving credit agreement to 
provide, depending on its available borrowing base, up to $100.0 for loans and 
letters of credit secured by AFC's receivables. At December 31, 1998, there 
were no outstanding borrowings under this credit facility. However, $61.1 of 
the facility was used as support for letters of credit.

In 1998, Armco and its bank group amended its inventory facility to provide, 
depending on its available borrowing base, up to $70.0 for loans and letters 
of credit secured by Armco's inventories. The credit agreement subjects Armco 
to certain restrictions and covenants related to, among other things, minimum 
net worth, leverage ratio and interest coverage ratio requirements. At 
December 31, 1998, there were no outstanding borrowings or letters of credit 
under this facility. Under both bank credit facilities, a total of $93.3 was 
available for borrowing at December 31, 1998. 

Armco anticipates that its capital expenditures for 1999 will total 
approximately $50.0 to $60.0. Armco expects that its 1999 cash requirements, 
including amounts for capital expenditures, debt service and preferred stock 
dividends will be paid out of existing cash balances and cash generated from 
operations.

In prior years, certain of Armco's financing arrangements included covenants 
that prohibited the payment of common stock dividends. These prohibitions have 
been eliminated; however, at December 31, 1998, certain outstanding financing 
arrangements contain financial tests which must be met before dividends can be 
paid. Currently, Armco meets these covenant requirements and is not prohibited 
from paying dividends under the terms of its credit facilities, long-term debt 
issues or under Ohio law. 

Armco is permitted to purchase shares of its capital stock under the terms of 
Ohio law only to the extent that it has positive equity surplus. At December 
31,1998, Armco had a negative equity surplus balance of $8.3.

On January 22, 1999, Armco's Board of Directors declared the regular quarterly 
dividends of $.525 per share on the $2.10 cumulative convertible preferred 
stock, Class A, and $.90625 per share on the $3.625 cumulative convertible 
preferred stock, Class A, each payable March 31, 1999 to shareholders of 
record on February 26, 1999. The Board of Directors also declared the regular 
quarterly dividend of $1.125 per share on the $4.50 cumulative convertible 
preferred stock, Class B, payable April 1, 1999, to shareholders of record on 
February 26, 1999.

Operations are generating strong cash flow, which is making it possible to 
reduce debt. Late in 1998, Armco issued $75 million of debt, which with other 
available funds, was used to redeem the remaining $111 million of higher 
interest rate debt in January 1999.


ENVIRONMENTAL MATTERS
In common with other U.S. manufacturers, Armco is subject to various federal, 
state and local environmental requirements. Armco has spent substantial 
amounts of money to control air and water pollution pursuant to applicable 
environmental requirements. Armco has also spent, and will continue to spend, 
substantial amounts for proper handling and disposal of waste material and for 
the environmental investigation and cleanup of properties. During the period 
1994 through 1998, Armco's capital expenditures for pollution control projects 
amounted to $36.4, including $1.4 in 1998. Along with capital investments and 
operating costs relating to environmental matters, from time to time Armco has 
been and may be subject to penalties and other requirements as a result of 
administrative action by regulatory agencies.

Statutory and regulatory requirements in this area continue to evolve and, 
accordingly, Armco cannot predict with certainty the type and magnitude of 
expenditures that will be required in the future. However, total expenditures 
for capital projects for pollution control during the five-year period from 
1999 through 2003 are estimated to be approximately $29.0. Of this amount, 
approximately $7.4 is related to control of air pollution as required by 
amendments to the federal Clean Air Act, corresponding state laws and 
implementing regulations. A substantial portion of these capital expenditures 
is also attributable to the control of water pollution under the Clean Water 
Act. Although it cannot predict precisely how changes in environmental 
requirements will affect its businesses, Armco does not believe such 
requirements would affect its competitive position. 
 
Armco is, and may in the future be, subject to other types of environmental 
claims and costs, for which it accrues when it is probable that a liability 
has been incurred and it is possible to reasonably estimate the amount or 
range of any such loss.

Armco is a defendant, or identified as a potentially responsible party in 
various pending claims regarding waste disposal sites. Joint and several 
liability could be imposed on Armco or other parties for these or similar 
matters; thus, theoretically, one party could be held liable for all costs 
related to a site. Though the outcome of such matters cannot be predicted with 
assurance, Armco's experience has been that, in most cases, ultimate liability 
is apportioned among Armco and other financially viable parties. Periodically, 
there are claims alleging property damage or personal injury in conjunction 
with waste disposal or releases. Armco is also subject to claims for 
contractual indemnification related to previously divested properties. If 
Armco disposes of additional properties, it may incur additional environmental 
exit costs. Armco accrues exit costs when it decides to dispose of a property 
or records a sale.

20  Armco 1998 Annual Report

While the outcome of environmental matters cannot be predicted with assurance, 
Armco believes that the ultimate liability for such matters, identified to 
date, will not materially affect its consolidated financial condition or 
liquidity. This belief is based on current facts and circumstances known to 
Armco, including current laws and regulations as well as Armco's experience 
with site remediation. However, it is possible that due to fluctuations in 
Armco's operating results, changes in the facts or circumstances of known 
matters, or the addition of significant new matters, environmental liabilities 
could have a material effect on the results of operations of future interim or 
annual periods. It is not possible to determine whether additional loss will 
occur or to reasonably estimate the amount or range of any such loss.

THE YEAR 2000 ISSUE
Many existing computer systems may not be able to appropriately interpret 
dates after December 31, 1999 because such systems allow only two digits to 
indicate a year in the date field. If not corrected, many computers and 
computer applications could fail or create erroneous results, causing safety, 
operational and financial problems. If such a failure were to occur to certain 
of its computer systems, Armco's manufacturing and financial systems could be 
temporarily shut down, resulting in a material adverse effect on its financial 
condition, liquidity and results of operations. In addition, the failure of 
vendor computer systems could cause interruption of deliveries of key supplies 
or utilities, which might result in similar material adverse impacts. Because 
of the complexity of the issues and the number of parties involved, Armco 
cannot reasonably predict with certainty the nature or likelihood of such 
impacts.

However, Armco, using its internal staff and outside consultants, is actively 
addressing this situation and anticipates that it will not experience a 
material adverse impact to its operations, liquidity or financial condition 
related to systems under its control. Armco has completed an assessment of 
substantially all business information, manufacturing and facility control 
systems to identify areas of concern. Armco is in the process of modifying or 
replacing noncompliant computer hardware and software used internally. In 
addition, Armco has surveyed its suppliers in regard to their Year 2000 
preparations, focusing on those suppliers most critical to its operations. 
Armco intends to continue to monitor the Year 2000 compliance efforts of its 
suppliers and to obtain, to the extent possible, assurances that they will be 
able to deliver their products and services without interruption. 

To prepare for the reasonably likely worst case scenario, Armco is developing 
a contingency plan designed to mitigate the effects on its operations in case 
certain of its systems or suppliers fail to perform as planned. This plan is 
expected to be completed by the end of the second quarter of 1999. Contingency 
planning will consist of providing all required resources to repair internal 
systems should they fail at critical times, as well as establishing additional 
inventories and back-up procedures in the event suppliers are unable to 
deliver raw materials and services in a timely manner. 

Armco has prioritized its efforts, planning to complete work on noncompliant 
systems in the most critical areas first, with the expectation that virtually 
all Year 2000 compliance activities, including system testing, will be 
completed by September 30, 1999. In this process, Armco has redirected its 
systems resources from noncritical projects to Year 2000 compliance 
activities, resulting in an immaterial increase in expense. In 1998, Armco 
spent approximately $6.0 on Year 2000 compliance activities and currently 
anticipates spending an additional $11.0 in 1999. These expenditures, which 
are expected to consist primarily of capital expenditures, outside consultants 
and internal personnel costs, have been and will be funded out of operating 
cash flows. 

NEW ACCOUNTING STANDARD
In 1998, the Financial Accounting Standards Board issued Statement of 
Financial Accounting Standards No. 133, Accounting for Derivative Instruments 
and Hedging Activities (SFAS No. 133). Armco intends to adopt the new standard 
when required in 2000. Armco does not expect that SFAS No. 133 will have a 
material effect on its financial statements; however, its effect, if any, will 
depend on Armco's exposure to derivative instruments at the time of adoption 
and thereafter.

FORWARD-LOOKING STATEMENTS 
Certain statements made in this Management's Discussion & Analysis, in the 
Notes to Consolidated Financial Statements and in the Letter to Shareholders 
contained in this Annual Report, reflect management's estimates and beliefs 
and are intended to be, and are hereby identified as, "forward-looking 
statements" for purposes of the safe harbor provisions of the Private 
Securities Litigation Reform Act of 1995. These include statements in the 
foregoing paragraphs entitled Outlook for 1999, Armco Financial Services Group 
(AFSG), Liquidity and Capital Resources, Environmental Matters, The Year 2000 
Issue and New Accounting Standard; and in Note 1, Summary of Significant 
Accounting Policies, relating to Concentration of Credit Risk and New 
Accounting Standard; Note 9, Litigation and Environmental Matters; and Note 
10, Discontinued Operations, relating to AFSG.

Armco cautions readers that such forward-looking statements involve risks and 
uncertainties that could cause actual results to differ materially from those 
currently expected by management. In addition to those noted in the statements 
themselves, these factors include, but are not limited to, the following: 
risks of a downturn in the general economy or in the highly cyclical steel 
industry; volatility in financial markets, which may affect invested pension 
plan assets and the calculation of benefit plan liabilities and expenses; 
changes in demand for Armco's products; unplanned plant outages, equipment 
failures or labor difficulties; actions by Armco's foreign and domestic 
competitors; unexpected outcomes of major litigation and contingencies; 
changes in U.S. trade policy and actions respecting imports; disruptions in 
the supply of raw materials; actions by reinsurance companies with which AFSG 
does business, or foreign or domestic insurance regulators; and changes in 
application or scope of environmental regulations applicable to Armco.

RESPONSIBILITY FOR FINANCIAL REPORTING
Armco's management prepared the financial statements presented in this Annual 
Report in accordance with generally accepted accounting principles in the 
United States. These principles require choices among alternatives and 
numerous estimates of financial matters. Armco believes the accounting 
principles chosen are appropriate in the circumstances, and the estimates and 
judgments involved in Armco's financial reporting are reasonable and 
conservative.

Armco's management is responsible for the integrity and objectivity of the 
financial information presented in this Annual Report. Armco maintains a 
system of internal accounting control and a program of internal audits. They 
are designed to provide reasonable assurance that the financial reports are 
fairly presented and that Armco employees comply with stated policies and 
procedures, including policies on the ethical conduct of business. Armco 
continually reviews and updates its policies and system of internal accounting 
control as businesses and business conditions change.

Management and the Audit Review Committee of the Board of Directors 
recommended, and the Board of Directors approved, the hiring of Deloitte & 
Touche LLP as independent auditors for Armco. Deloitte & Touche LLP expresses 
an informed professional opinion on Armco's financial statements.

The Audit Review Committee, composed solely of independent outside directors, 
oversees Armco's public financial reporting. The Audit Review Committee meets 
periodically with management, Deloitte & Touche LLP and Armco's internal 
auditors, both individually and jointly, to discuss internal accounting 
control and financial reporting matters. Deloitte & Touche LLP and Armco's 
internal auditors have free access to the Audit Review Committee to discuss 
any matters.

We believe Armco's internal control system, combined with the activities of 
the internal and independent auditors and the Audit Review Committee, provides 
you reasonable assurance of the integrity of our financial reporting.

Armco, Its Shareholders and Directors:

We have audited the accompanying consolidated balance sheets of Armco Inc. and 
subsidiaries as of December 31, 1998 and 1997, and the related consolidated 
statements of income and comprehensive income and of cash flows for each of 
the three years in the period ended December 31, 1998. These financial 
statements are the responsibility of the Company's management. Our 
responsibility is to express an opinion on these financial statements based on 
our audits.

We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free of 
material misstatement. An audit includes examining, on a test basis, evidence 
supporting the amounts and disclosures in the financial statements. An audit 
also includes assessing the accounting principles used and significant 
estimates made by management, as well as evaluating the overall financial 
statement presentation. We believe that our audits provide a reasonable basis 
for our opinion.

In our opinion, such consolidated financial statements present fairly, in all 
material respects, the financial position of Armco Inc. and subsidiaries at 
December 31, 1998 and 1997, and the results of their operations and their cash 
flows for each of the three years in the period ended December 31, 1998, in 
conformity with generally accepted accounting principles.

As discussed in Note 2 to the financial statements, in 1998 Armco Inc. changed 
its method of amortizing unrecognized net gains and losses related to its 
obligations for pension and other postretirement benefits.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Dollars in millions, except per share amounts)

- ------------------------------------------------------------------------------
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

GENERAL
The accompanying financial statements consolidate the accounts of Armco and 
all subsidiaries in which Armco has a controlling interest.

The preparation of financial statements in conformity with generally accepted 
accounting principles requires management to make estimates and assumptions 
that affect the reported amounts of assets and liabilities and the disclosure 
of contingent assets and liabilities at the date of the financial statements 
and the reported amounts of revenues and expenses during the reporting period. 
Actual results could differ from those estimates.

INVESTMENTS
Armco considers all highly liquid investments purchased with a maturity of 
three months or less to be cash equivalents. Cash equivalents consist of 
commercial paper, corporate notes, time deposits and other money market 
instruments, including mutual funds.

Under the definitions provided in Statement of Financial Accounting Standards 
(SFAS) No. 115, Accounting for Certain Investments in Debt and Equity 
Securities, Armco has securities which have been classified as held to 
maturity and are, therefore, recorded at amortized cost. The carrying amounts 
for these securities approximate fair value due to the short maturities of the 
instruments. At December 31, 1998 and 1997, these securities were as follows:


- ------------------------------------------------------------------------------
                                                             1998     1997
- ------------------------------------------------------------------------------
                                                               
Cash equivalents                                            $256.7   $180.4
Short-term liquid investments                                  7.0      5.0
Restricted collateral deposits                                10.1     15.5
- ------------------------------------------------------------------------------
Total securities                                            $273.8   $200.9
- ------------------------------------------------------------------------------

The restricted collateral deposits are primarily invested in certificates of 
deposit which mature within one year and are principally used as security for 
self-insurance programs and environmental and litigation bonds. These 
securities are reported in other current assets or other investments. The 
classification is determined based on the expected term of the collateral 
requirement and not necessarily the maturity date of the underlying 
securities. 

At December 31, 1998 and 1997, other investments also included $11.2 for 
Armco's limited partnership interest in North American Stainless. It is not 
practicable to estimate the fair value of this closely held limited 
partnership, in which Armco's ownership interest is less than 5%. At December 
31, 1998 and 1997, Armco had no material investments in derivative financial 
instruments. 

INVENTORIES
Inventories are valued at the lower of cost or market. Cost of inventories at 
most domestic operations is measured on the LIFO - Last In, First Out - 
method. Other inventories are measured principally at average cost. Inventory 
balances at December 31, 1998 and 1997 were as follows:


- ------------------------------------------------------------------------------
                                                            1998        1997
- ------------------------------------------------------------------------------

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

RESEARCH AND DEVELOPMENT COSTS
Armco conducts a broad range of research and development activities. These 
activities are aimed at improving existing products and manufacturing 
processes and developing new products and processes. Research and development 
costs are recorded as expense when incurred. The amounts incurred in 1998, 
1997 and 1996 were $14.2, $15.3 and $13.1, respectively.

PROPERTY, PLANT AND EQUIPMENT
Depreciation is computed using the straight-line method based on the estimated 
useful lives of the related assets. Leasehold improvements are depreciated 
over the shorter of the life of the related asset or the life of the lease. 
Generally, Armco depreciates its property, plant and equipment at annual rates 
of 5% for land improvements, 3% to 5% for buildings and 5% to 33% for 
machinery and equipment.

Armco's property, plant and equipment balances at December 31, 1998 and 1997 
were as follows:


- ------------------------------------------------------------------------------
                                                             1998       1997
- ------------------------------------------------------------------------------

Property, plant and equipment-net                         $  621.8   $  652.5
- ------------------------------------------------------------------------------

Armco had commitments to purchase property, plant and equipment (including 
unexpended amounts relating to projects substantially underway) totaling 
approximately $17.8 at December 31, 1998. 

GOODWILL AND OTHER INTANGIBLE ASSETS
Goodwill and other intangible assets primarily consist of goodwill recorded in 
connection with the acquisition of Cyclops Industries, Inc. on April 24, 1992. 
This goodwill is being amortized using the straight-line method over 40 years. 
Also included are goodwill and other intangible assets acquired in the 
purchase of Douglas Dynamics, LLC on July 2, 1991. These assets are being 
amortized over their estimated

26 Armco 1998 Annual Report

useful lives, the majority of which do not exceed 17 years. Annual 
amortization expense for 1998, 1997 and 1996 was $6.1, $6.5 and $6.9, 
respectively. At December 31, 1998 and 1997, accumulated amortization of 
goodwill and other intangible assets was $42.6 and $36.5, respectively.

Armco assesses whether its goodwill and other intangible assets are impaired 
as required by SFAS No. 121, Accounting for the Impairment of Long-Lived 
Assets and for Long-Lived Assets to be Disposed Of, based on an evaluation of 
undiscounted projected cash flows through the remaining amortization period. 
If an impairment exists, the amount of such impairment is calculated based on 
the estimated fair value of the asset. 

EARNINGS PER SHARE
The following information was used in the calculation of basic and diluted 
earnings per share:

At the end of each year, Armco had outstanding exercisable stock options and 
convertible preferred stock whose exercise or conversion could, under certain 
circumstances, further dilute earnings per share. The following shares of 
potentially issuable common stock were not included in the above weighted 
average shares outstanding because to do so would have had an antidilutive

ENVIRONMENTAL LIABILITIES
Armco has participated in or funded various cleanup efforts at sites where its 
facilities have disposed of wastes, including sites located on its own 
properties. Costs related to these efforts are accrued when it is probable 
that a liability has been incurred and the amount of that liability can be 
reasonably estimated. It is Armco's policy not to accrue environmental exit 
costs with respect to ongoing businesses until a decision is made to dispose 
of the property.

CONCENTRATION OF CREDIT RISK
Armco is primarily a producer of stainless and electrical steels and steel 
products, which are sold to a number of markets, including automotive, 
industrial machinery and equipment, construction, power distribution and 
appliances. Armco sells domestically to customers primarily in the Midwestern 
and Eastern United States, while approximately 12% of sales are to foreign 
customers, primarily in Canada, Mexico and Western Europe. Approximately 37% 
of trade receivables outstanding at December 31, 1998 are due from businesses 
that supply the U.S. automotive industry. Except in a few situations where the 
risk warrants it, Armco does not require collateral on trade receivables; and 
while it believes its trade receivables will be collected, Armco anticipates 
that in the event of default it would follow normal collection procedures. 
Overall, credit risk related to Armco's trade receivables is limited due to 
the large number of customers in differing industries and geographic areas.

NEW ACCOUNTING STANDARD
In 1998, the Financial Accounting Standards Board issued Statement of 
Financial Accounting Standards No. 133, Accounting for Derivative Instruments 
and Hedging Activities (SFAS No. 133). Armco intends to adopt the new standard 
when required in 2000. Armco does not expect that SFAS No. 133 will have a 
material effect on its financial statements; however, its effect, if any, will 
depend on Armco's exposure to derivative instruments at the time of adoption 
and thereafter.

FAIR VALUE
The fair value of financial instruments is disclosed in Notes 1 and 4.


- ------------------------------------------------------------------------------
2. PENSION AND OTHER POSTRETIREMENT BENEFITS

Armco provides noncontributory pension benefits to most employees and provides 
various health care and life insurance benefits to most retirees. Retiree 
health and life insurance benefits are funded as claims are paid. Pension 
benefits are funded as required. As of December 31, 1998, pension funding 
credits of $57.3 were available to offset future minimum funding requirements 
of the Employee Retirement Income Security Act of 1974. 

The components of net periodic benefit cost, including amounts related to 
divested units, are as follows:

                                                  Armco 1998 Annual Report  27

Effective January 1, 1998, Armco changed its method of amortizing unrecognized 
net gains and losses related to its obligations for pensions and other 
postretirement benefits. In 1998, Armco recognized income of $237.5, or $2.20 
per share of common stock ($1.88 per diluted share), for the cumulative effect 
of this accounting change. 

At the time it originally adopted the standards governing accounting for 
pensions and other postretirement benefits, Armco chose to use a minimum 
amortization method whereby unrecognized net gains and losses, to the extent 
they exceeded 10% of the larger of the benefit obligations or plan assets, 
were amortized over the average remaining service life of active participants. 
At Armco, the average remaining service life is approximately 15 years. Use of 
this method, however, resulted in the accumulation of $419.3 of unrecognized 
net gains for pensions and other postretirement benefits through 1997. Under 
the new accounting method, Armco recognizes into income, as a fourth quarter 
adjustment, any unrecognized net gains and losses which exceed the 10% 
corridor, as described above, and amortizes amounts inside the corridor over 
the average remaining service life of active participants. Adoption of the new 
method increased 1998 income from continuing operations by approximately $3.0, 
or $0.03 per share of common stock.

At December 31, 1998, pension plan assets include 3.6 million shares of Armco 
common stock with a fair value of $15.7. No Armco stock was held by the plans 
at December 31,1997.

For measurement purposes, a 4.75% annual increase in health care costs is 
assumed for post-age 64 retirees. Health care costs for pre-age 65 retirees 
are assumed to increase 6% in 1999. This rate declines annually until it 
reaches 4.75% in 2001 and thereafter.

Assumed health care cost trend rates have a significant effect on the amounts 
reported for health care plans. A one percentage-point change in assumed 
health care cost trend rates would have the following effects:


- ------------------------------------------------------------------------------
                                            One Percentage-   One Percentage-

Increase (decrease) in total of service and 
  interest cost components                     $  5.6             $ (5.0) 
Increase (decrease) in postretirement
  benefit obligation                             63.5              (57.5) 
- ------------------------------------------------------------------------------

The projected benefit obligation, accumulated benefit obligation and fair 
value of plan assets for plans with accumulated benefit obligations in excess 
of plan assets, including unfunded nonqualified pension plans, was $24.4, 
$19.4 and $1.3, respectively, at December 31, 1998, and $19.3, $16.2 and $1.2, 
respectively, at December 31, 1997. 

In addition to the defined benefit pension plans, most employees are eligible 
to participate in various defined contribution plans. Total company expense 
related to these plans was $7.4, $6.7 and $2.9 for 1998, 1997 and 1996, 
respectively. A portion of the expense of these plans varies based on Armco's 
profitability.

28  Armco 1998 Annual Report

EMPLOYEE BENEFIT OBLIGATIONS OF FORMER BUSINESS UNITS
Included in employee benefit liabilities is the present value of estimated 
pension and health care benefits for former employees associated with 
facilities that have been divested. Sundry other-net includes income of $24.2 
in 1998 and expense of $2.0 and $22.1 in 1997 and 1996, respectively, related 
to these liabilities. The decrease in costs in 1997 and 1998 was primarily due 
to continuing favorable investment returns on pension plan assets and lower 
than expected increases in medical benefit costs. 

- ------------------------------------------------------------------------------
3. INCOME TAXES

Armco files a consolidated U.S. federal income tax return. This return 
includes all domestic companies 80% or more owned by Armco and the 
proportionate share of Armco's interest in partnership investments. State tax 
returns are filed on a consolidated, combined or separate basis depending on 
the applicable laws relating to Armco and its domestic subsidiaries.

The United States and foreign components of income before income taxes consist 
of the following:


- ------------------------------------------------------------------------------
                                                    1998     1997     1996

During 1998, Armco's net operating loss carryforwards decreased by 
approximately $54.3 due to taxable income generated in the year. Armco's 
capital loss carryforward decreased by approximately $50.4, of which $14.3 was 
the result of taxable capital gains generated in the year, and $36.1 was due 
to the expiration of unused capital losses available from 1993. The difference 
between pretax book income of $115.4 and 1998 taxable income is primarily due 
to costs associated with employee benefits, environmental and restructuring 
actions, which had been accrued for financial accounting purposes in prior 
years, but actually paid in 1998; and additional net deductions resulting from 
the 1998 operations of the Armco Financial Services Group.

At December 31, 1998, Armco had capital loss and net operating loss (NOL) 
carryforwards for federal tax purposes expiring as follows:

Armco has $698.0 in U.S. alternative minimum tax net operating losses. 
Additionally, Armco has $13.0 of alternative minimum tax credits that have no 
expiration. 

Deferred income taxes reflect the net tax effects of (a) temporary differences 
between the carrying amounts of assets and liabilities for financial reporting 
purposes and the amounts used for income tax purposes and (b) operating loss 
and tax credit carryforwards. At December 31, 1998 and 1997, the net deferred 
tax asset, included on the Consolidated Balance Sheets, was as follows:


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

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

Management believes it is more likely than not that Armco will generate future 
taxable income sufficient to realize that portion of the tax benefit 
associated with future deductible temporary differences and NOL carryforwards, 
represented by the $325.0 net deferred tax asset. Armco prepares a calculation 
annually in which it estimates future income and schedules the future effects 
of temporary differences and NOL carryforwards. Because any forecast has 
inherent uncertainties and because of the structural changes Armco has 
undergone over the last nine years, Armco uses what it believes to be 
conservative estimates and assumptions. Considering all available evidence, 
both positive and negative, Armco periodically determines if there has been a 
significant change in the net deferred tax asset. During the last several 
years, based on forecasts and consideration of available evidence, Armco 
believes that there has been no significant change in the amount of its net 
deferred tax asset.

Armco's belief that realization of its net deferred tax asset is more likely 
than not is based on, among other factors, changes in operations that have 
occurred during the 1990s, as well as consideration of available tax planning 
strategies. Specifically, cost savings resulting from new capital investments 
are being realized and are expected to continue to improve operating results. 
Armco has operated in a highly cyclical industry and, consequently, has had a 
history of generating and then utilizing significant amounts of NOL 
carryforwards. In 1997 and 1998, in addition to using its temporary 
differences, principally related to employee benefit obligations, to reduce 
taxable income, Armco utilized approximately $70.0 of its NOL carryforwards. 
These were the first two years of taxable income for Armco after seven years 
of tax losses. However, if Armco is unable to generate sufficient taxable 
income in the future through operating results, increases in the valuation 
allowance may be required through a charge to income. On the other hand, if 
Armco achieves sufficient profitability to utilize a greater portion of the 
deferred tax asset, the valuation allowance will be reduced through a credit 
to income.

United States income tax returns of Armco for 1994 and prior years have been 
subject to examination by the Internal Revenue Service and are closed to 
assessments. However, the NOL carryforwards from some of these years remain 
open to adjustment. Armco has been in a cumulative NOL carryforward position 
since 1983 and believes that it has sufficient loss carryforwards in excess of 
any potential audit adjustments that might be made by the Internal Revenue 
Service for any open years.

Maturities of existing long-term debt during the five years ending December 
31, 2003, are as follows: 1999, $116.9; 2000, $5.9; 2001, $0.8; 2002, $0.8 and 
2003, zero. The 1999 maturities include the January 14, 1999 redemption of 
$111.0 of the 9-3/8% Senior Notes. These notes were redeemed with the proceeds 
of the December 1998 issuance of $75.0 of 8-7/8% Senior Notes due 2008 and 
other available funds. In the first quarter of 1999, Armco recognized an 
extraordinary loss of $2.8 related to this redemption.

30  Armco 1998 Annual Report

At December 31, 1998, the fair value of Armco's long-term debt, including 
current maturities, was approximately $372.9. This amount was determined by 
calculating a value based on cash flow yield to maturity and comparing that 
amount to market information where possible. The fair value estimate was based 
on pertinent information available to management as of December 31, 1998. 
Management is not aware of any significant factors that would materially alter 
this estimate since that date. The fair value of Armco's long-term debt, 
including current maturities, at December 31, 1997, was approximately $347.4.

At December 31, 1998 and 1997, $13.2 and $50.2, respectively, of long-term 
debt, including current maturities, represented financing utilized to 
construct certain of Armco's fixed assets, which are pledged as collateral on 
these loans.

During 1997, Armco recorded an extraordinary loss upon retiring certain of its 
outstanding debt of $3.0 or $0.03 per share of common stock.

BANK CREDIT AGREEMENTS
At December 31, 1998, Armco had in place two bank credit facilities, totaling 
$170.0. In 1998, the terms of these facilities were extended and both will 
expire in 2001. 

Under a receivables facility, Armco sells substantially all its trade 
receivables to a wholly owned subsidiary, Armco Funding Corporation (AFC). In 
1998, AFC and its bank group amended its revolving credit agreement to 
provide, depending on its available borrowing base, up to $100.0 for loans and 
letters of credit secured by AFC's receivables. At December 31, 1998, there 
were no outstanding borrowings under this credit facility; however, $61.1 of 
the facility was used as support for letters of credit.

In 1998, Armco and its bank group amended its revolving credit agreement to 
provide, depending on its available borrowing base, up to $70.0 for loans and 
letters of credit secured by Armco's inventories. This credit agreement 
subjects Armco to certain restrictions and covenants related to, among other 
things, minimum net worth, leverage ratio and interest coverage ratio 
requirements. At December 31, 1998, there were no outstanding borrowings or 
letters of credit under this facility. Under both bank credit facilities, a 
total of $93.3 was available for borrowing at December 31, 1998.

LONG-TERM LEASES
Rental expense under operating leases was $6.7 in 1998, $6.9 in 1997 and $7.7 
in 1996. At December 31, 1998, commitments to make future minimum lease 
payments for operating leases are $4.3 in 1999, $2.9 in 2000, $2.4 in 2001, 
$3.0 in 2002, $1.3 in 2003 and $1.2 thereafter.

5. SHAREHOLDERS' EQUITY (DEFICIT)

PREFERRED STOCK
Armco has outstanding two classes of preferred stock that rank equally with 
respect to dividend payments, redemption and liquidation rights. The preferred 
stock ranks senior to Armco's common stock with respect to dividends and upon 
liquidation. At December 31, 1998 and 1997, there were authorized and issuable 
in series, 6,697,231 shares of Class A preferred stock with no par value and 
5,000,000 shares of $1 par value Class B preferred stock.

SHAREHOLDER RIGHTS PLAN
In 1996, Armco adopted a Shareholder Rights Plan designed to deter coercive 
takeover tactics and prevent an acquirer from gaining control of Armco without 
offering a fair price to all of Armco's shareholders. Under the terms of the 
plan, preferred stock purchase rights were distributed as a dividend at the 
rate of one right for each share of common stock held as of the close of 
business on June 26, 1996. Until the rights become exercisable, common stock 
issued will also have one right attached. Each right will entitle shareholders 
to buy one two-hundredth of a share of a currently unissued series of Class A 
participating preferred stock of Armco at an exercise price of $20. Each right 
will thereafter entitle the holder to receive upon exercise, common stock or, 
in certain circumstances, preferred stock or other securities or assets of the 
company having a value of $40. The rights will be exercisable only if a person 
or group acquires beneficial ownership of 

                                                  Armco 1998 Annual Report  31

20% or more of Armco's common stock or announces a tender or exchange offer, 
after which such person or group would beneficially own 20% or more of the 
common stock, or if the Board of Directors declares any person to be an 
"adverse person" as defined in the plan. A total of 750,000 shares of Class A 
participating preferred stock have been reserved for issuance upon exercise of 
the rights.

Armco, except as otherwise provided in the plan, will generally be able to 
redeem the rights at $0.0025 per right at any time during a ten-day period 
following public announcement that a 20% position in Armco has been acquired 
or after the effective date the Board of Directors declares any person to be 
an "adverse person." During this ten-day period, Armco may also extend the 
time during which it may redeem the rights. The rights are not exercisable 
until the expiration of the redemption period. The rights will expire on June 
26, 2006. 

ACCUMULATED DEFICIT, DEFERRED COMPENSATION AND ACCUMULATED OTHER COMPREHENSIVE

DIVIDENDS
In prior years, certain of Armco's financing arrangements included covenants 
that prohibited the payment of common stock dividends. These prohibitions have 
been eliminated; however, at December 31, 1998, certain outstanding financing 
arrangements contain financial tests which must be met before dividends can be 
paid. Currently, Armco meets these covenant requirements and is not prohibited 
from paying dividends under the terms of its credit facilities, long-term debt 
issues or under Ohio law. 

Armco is permitted to purchase shares of its capital stock under the terms of 
Ohio law only to the extent that it has positive equity surplus. At December 
31,1998, Armco had a negative equity surplus balance of $8.3.

The Board of Directors at its January 1999 meeting declared the regular 
quarterly dividends payable on both series of Armco's Class A preferred stock 
and on its Class B preferred stock. 


- ------------------------------------------------------------------------------
6. COMMON STOCK OPTIONS

Armco maintains plans that provide for granting options to purchase common 
stock for not less than 100% of its market price on the date the option is 
granted. The vesting period for stock options granted under these plans is two 
years from the date of grant and, although they may terminate earlier under 
certain conditions, stock options generally expire 10 years after the grant 
date. Armco also has plans that provide for issuing stock, subject to 
restrictions as to sale and forfeiture over a three- to five-year period. 
Under certain circumstances, this vesting schedule may be accelerated by one 
year.

At December 31, 1998, 5,492,769 shares of common stock were available for 
granting of awards under these plans. During 1996, 1997 and 1998, stock option 
activity was as follows:

In 1996, Armco adopted SFAS No. 123, Accounting for Stock-Based Compensation. 
SFAS No. 123 provides that companies may change their method of accounting for 
stock options to a fair value method using an option pricing model. Armco uses 
the intrinsic value approach specified in Accounting Principles Board Opinion 
No. 25 in accounting for stock options and did not change from this method 
upon adoption of the new standard. Had Armco changed its accounting method, 
its net income for 1998 would have been reduced by $1.7 to $345.4, or $3.04 
per basic share and $2.67 per diluted share. Net income for 1997 would have 
been reduced by $1.2 to $75.6, or $0.54 per basic and diluted share, and net 
income for 1996 would have been reduced by $1.7 to $30.8, or $0.12 per basic 
and diluted share. These pro forma adjustments were calculated using the 
Black-Scholes option pricing model under the following assumptions in each 
year:


- ------------------------------------------------------------------------------
                                                     1998     1997     1996
- ------------------------------------------------------------------------------
                                                            
Risk free interest rate                              5.5%    6.25%      5.5%
Expected volatility                                   40%      35%       30%
Expected life of options                          5 years  5 years   5 years
Expected dividends                                   None     None      None
- ------------------------------------------------------------------------------

Based on the option pricing model, options granted during 1998, 1997 and 1996 
had fair values of $2.32, $1.72 and $1.90 per share, respectively. 

During 1998, 1997 and 1996, Armco issued to certain employees 786,562, 646,013 
and 570,158 shares of common stock, subject to restrictions, with weighted 
average grant-date fair values of $5.31, $4.07 and $5.69 per share, 
respectively. Total compensation cost recognized in income for stock-based 
employee compensation awards was $1.7 in 1998, $1.6 in 1997 and $1.1 in 1996.


- ------------------------------------------------------------------------------
7. SPECIAL CHARGES

In 1996, Armco recognized a special charge of $5.9 to record a loss on the 
sale of its nonresidential construction business, which was sold effective 
January 1, 1997. The charge primarily related to the writedown of assets and 
recognition of additional employee benefit liabilities.

Also in 1996, Armco recorded a $2.9 special charge primarily for the writedown 
of assets and severance costs related to its decision to discontinue a line of 
light truck equipment manufactured by Armco's snowplow and ice control 
products business.


- ------------------------------------------------------------------------------
8. SEGMENT INFORMATION

Armco's reportable operating segments are three separately managed business 
units that offer different products and services. They are: (1) Specialty 
Flat-Rolled Steels, consisting of plants in Butler, Pennsylvania and 
Coshocton, Dover, Mansfield and Zanesville, Ohio that produce and finish flat-
rolled stainless, electrical and galvanized carbon steels for the automotive, 
industrial machinery and equipment, construction, and service center markets; 
and international trading companies, that buy and sell steel and manufactured 
steel products. (2) Tubular Products, consisting of Sawhill Tubular with 
operations in Sharon and Wheatland, Pennsylvania and Warren, Ohio that produce 
steel pipe and tubular products for the industrial machinery, construction and 
appliance markets. And, (3) Other Businesses, consisting of Douglas Dynamics, 
LLC with plants in Milwaukee, Wisconsin, Rockland, Maine and Johnson City, 
Tennessee, that manufacture snowplows and ice control equipment for four-wheel 
drive light trucks and Greens Port Industrial Park, which leases land, 
buildings and rail car storage facilities and operates a deep water loading 
dock on a ship channel in Houston, Texas. A substantial portion of the Other 
Businesses segment represents the snowplow and ice control products business.

Accounting policies of the segments are the same as those described in the 
summary of significant accounting policies in Note 1. Armco's management 
evaluates segment performance based on income from continuing operations. 
Armco does not allocate interest expense, interest income, income tax expense 
or employee benefits for certain divested businesses to its segments.

Armco's segment information is as follows:

9. LITIGATION AND ENVIRONMENTAL MATTERS

Armco and its subsidiaries are involved in various pending claims regarding 
product liability, patent, employee benefits, environmental matters, 
reinsurance and insurance arrangements, and other matters arising out of the 
conduct of Armco's business. The actual liability for legal claims against 
Armco at December 31, 1998 cannot be determined, but in Armco's opinion, based 
on current facts and circumstances, the ultimate liability resulting from such 
claims will not materially affect its consolidated financial position or 
liquidity. However, it is possible that due to fluctuations in Armco's 
operating results, future developments with respect to such matters could have 
a material effect on its results of operations in future interim or annual 
periods. 

In common with other U.S. manufacturers, Armco is subject to various federal, 
state and local environmental laws. These laws necessitate expenditures to 
meet environmental compliance requirements at Armco's facilities and to 
remediate sites where contamination has occurred. Compliance costs are either 
expensed as they are incurred or, when appropriate, are recorded as capital 
expenditures. Environmental exit costs are accrued when a decision is made to 
dispose of a property or a sale is recorded.

Armco is a defendant, or identified as a potentially responsible party, in 
proceedings alleging liability for remediation, property damage or personal 
injury related to certain waste disposal sites. Armco has also received claims 
for indemnification for some properties it has previously owned or leased. In 
most cases involving waste disposal sites, Armco is one of many potentially 
responsible parties. In these cases, joint and several liability could be 
imposed on Armco or other parties; thus, theoretically, one party could be 
held liable for all costs related to a site. However, based on its experience 
and a review of current claims, Armco believes that any ultimate liability 
will be apportioned among Armco and other financially viable parties. Armco 
accrues its estimate of remediation and other costs for sites where it is 
probable that a liability has been incurred and the amount can be reasonably 
estimated.

In establishing liabilities, Armco assesses the range of reasonably estimated 
outcomes and determines the most likely outcome for its liabilities within the 
range. Costs are estimated based on experience with site remediation, an 
understanding of current environmental laws and regulations, environmental 
assessments, the existence of other financially viable parties, expected 
remediation methods and the years in which Armco is expected to make payments 
toward each remediation (which range from the current year to 30 years or more 
in the future). These liabilities are not discounted. The cost estimates are 
reviewed regularly to assess changed conditions, including current 
interpretations of environmental laws and regulations, and changes in 
remediation technology and methods. Adjustments are made if changed conditions 
have a significant effect on cost estimates. Liabilities have not been 
adjusted for expected recoveries from insurers or other parties. 

The recorded amounts are currently believed by management to be sufficient. 
However, such estimates could significantly change in future periods to 
reflect new laws or regulations, advances in technologies, additional sites 
requiring remediation, new requirements at existing sites and Armco's share of 
liability at multi-party sites. It is not possible to determine whether 
additional loss, due to such changed circumstances, will occur or to 
reasonably estimate the amount or range of any potential additional loss.

At December 31, 1998, Armco had recorded on its Consolidated Balance Sheets, 
$11.4 in other current liabilities and $50.4 in other long-term liabilities 
for estimated probable costs relating to legal and environmental matters.

10. DISCONTINUED OPERATIONS 

AEROSPACE AND STRATEGIC MATERIALS
Oregon Metallurgical Corporation (Oremet), formerly 80% owned by Armco, was 
part of the Aerospace and Strategic Materials business segment that Armco sold 
in 1985. Prior to the sale, Armco filed a suit on behalf of Oremet in the U.S. 
Claims Court, claiming refunds and interest on federal and state taxes. 
Pursuant to the sales agreement, Armco retained the benefit of its share of 
any proceeds of this action, net of taxes imposed on Oremet and the buyer. In 
1996, Armco and Oremet reached agreement with the Internal Revenue Service 
that a previous refund of taxes and interest should not itself have been 
taxable to Oremet, further increasing the net proceeds, which resulted in 
Armco recording an additional $6.5 gain on the sale. In 1997, Armco received 
an additional $2.7 in state and federal tax refunds.

ARMCO FINANCIAL SERVICES GROUP (AFSG)
Armco's investment in AFSG represents the net assets of its discontinued 
insurance and finance leasing businesses, which have been largely liquidated. 
The insurance companies, including Northwestern National Insurance Company 
(NNIC), have stopped writing new business and are being "run off." These 
companies are accounted for as discontinued operations under the liquidation 
basis of accounting, whereby future cash inflows and outflows are considered. 
Armco believes, based on current facts and circumstances, including the 
opinion of outside actuaries, that future changes in estimates of net losses 
relating to the ultimate liquidation of AFSG will not be material to Armco's 
financial position or liquidity. The following sets forth AFSG's consolidated 
summarized financial information at December 31, 1998:

34  Armco 1998 Annual Report

At December 31, 1998, AFSG's invested assets included $23.0 of various Senior 
Notes of Armco. On January 14, 1999, AFSG tendered $5.0 of the Senior Notes, 
which were redeemed by Armco on that date (see Note 4).

Currently, insurance regulators having supervisory authority over the AFSG 
insurance companies retain substantial control over certain transactions, 
including the payment of dividends to Armco. 

In March 1997, North Atlantic Insurance Company, a group of international 
insurance companies previously affiliated with AFSG but sold in 1991, filed an 
application for voluntary liquidation in the United Kingdom. As a result of 
this voluntary liquidation filing, certain claims have been asserted against 
NNIC by insureds of North Atlantic. NNIC is defending these claims as well as 
pursuing related claims against third parties and North Atlantic.

There are various pending matters relating to litigation, arbitration and 
regulatory affairs, including the above-mentioned voluntary liquidation. The 
ultimate liability from such matters at December 31, 1998 cannot be determined 
but, in Armco's opinion, based on current facts and circumstances and the 
views of outside counsel and advisors, any liability resulting will not 
materially affect Armco's financial position or liquidity. However, it is 
possible that due to fluctuations in Armco's results, future developments with 
respect to changes in the ultimate liability could have a material effect on 
future interim or annual results of operations.
