CLAYTON, Mo., Jan. 31, 2011 /PRNewswire/ -- Olin Corporation (NYSE: OLN) announced today that its fourth quarter 2010 net income was $2.0 million, or $0.02 per diluted share, which compares to net income of $21.8 million, or $0.28 per diluted share in the fourth quarter of 2009. Fourth quarter 2010 results included a previously announced pretax restructuring charge of $34.2 million and the fourth quarter of 2009 results included $37.0 million of pretax recoveries of environmental costs incurred and expensed in prior periods. Sales in the fourth quarter of 2010 were $385.4 million, compared to $350.9 million in the fourth quarter of 2009.

Joseph D. Rupp, Chairman, President, and Chief Executive Officer said, "Fourth quarter 2010 results from both our Chlor Alkali and Winchester businesses exceeded our expectations. Our Chlor Alkali business earned $36.5 million in the quarter, reflecting better than expected volumes and pricing. Year-over-year chlorine and caustic soda volumes improved 12%, as the impact of normal seasonal slowdown was less pronounced than we expected. ECU netbacks improved 11% from the third quarter 2010 level and were 21% higher than the fourth quarter 2009 level. The operating rate in the fourth quarter of 2010 was 80% compared to 70% in the fourth quarter of 2009. Winchester's fourth quarter earnings were $3.6 million and full year 2010 earnings were $63.0 million, which represented the second most profitable year in its history.

"The fourth quarter pretax restructuring charge of $34.2 million, approximately 60% of which is non-cash, reflects the plans we announced in December to exit the use of mercury cell technology in the Chlor Alkali manufacturing process by the end of 2012 and the relocation of the Winchester centerfire ammunition manufacturing operations from East Alton, Illinois to Oxford, Mississippi. Fourth quarter 2010 results also included a $1.6 million pretax recovery for environmental costs incurred and expensed in prior periods and a $1.4 million pretax recovery of a previously written off investment.

"Net income in 2010 was $64.8 million, or $0.81 per diluted share, compared to $135.7 million, or $1.73 per diluted share in 2009. In addition to the fourth quarter pretax restructuring charge and the investment recovery, the 2010 full year results also included $7.2 million of pretax recoveries for environmental costs incurred and expensed in prior periods. 2009 full year results included $82.1 million of pretax recoveries for environmental costs incurred and expensed in prior periods and a $4.6 million pretax reduction in expense associated with the favorable resolution of a capital tax matter in Canada.

"First quarter 2011 net income is forecast to be in the $0.20 to $0.25 per diluted share range. Chlor Alkali expects to see continued improvement in the first quarter segment earnings compared to the fourth quarter of 2010 reflecting the positive impact of the 2010 price increase announcements. Earnings in the Winchester segment, which is facing pressure from higher commodity costs, are expected to improve compared to the fourth quarter but be lower than first quarter 2010 levels. The first quarter 2011 net income forecast does not include any favorable income tax adjustments."

SEGMENT REPORTING

We define segment earnings as income (loss) before interest expense, interest income, other income, and income taxes and include the results of non-consolidated affiliates in segment earnings consistent with management's monitoring of the operating segments.

CHLOR ALKALI PRODUCTS

Chlor Alkali product sales for the fourth quarter of 2010 were $272.7 million compared to $224.9 million in the fourth quarter of 2009. Fourth quarter 2010 chlorine and caustic soda volumes increased 12% compared to the fourth quarter 2009 levels. Volumes for potassium hydroxide and hydrochloric acid increased 17% in the fourth quarter of 2010 compared to the fourth quarter of 2009. Bleach volumes increased 16% during the fourth quarter of 2010 compared to the fourth quarter of 2009. ECU netbacks in the fourth quarter of 2010 improved 21% compared to the fourth quarter of 2009. Freight costs included in the ECU netbacks in the fourth quarter of 2010 decreased 5% compared to the fourth quarter of 2009, reflecting higher pipeline sales from the St. Gabriel, Louisiana facility, which did not operate until late in the fourth quarter of 2009. Fourth quarter 2010 Chlor Alkali segment earnings of $36.5 million increased compared to fourth quarter of 2009 earnings of $5.2 million due to higher prices and higher volumes.

WINCHESTER

Winchester fourth quarter 2010 sales were $112.7 million compared to $126.0 million in the fourth quarter of 2009. Fourth quarter 2010 commercial sales declined compared to the fourth quarter of 2009. Winchester's fourth quarter 2010 segment earnings were $3.6 million compared to $9.5 million in the fourth quarter of 2009. The decrease in segment earnings reflects the combination of lower volumes and higher commodity, other material and manufacturing costs, partially offset by improved pricing.

CORPORATE AND OTHER COSTS

Pension income included in the fourth quarter 2010 Corporate and Other segment was $6.4 million, compared to income of $5.5 million in the fourth quarter of 2009.

Fourth quarter charges to income for environmental investigatory and remedial activities were less than $0.1 million in 2010, which includes $1.6 million of pretax recoveries for environmental costs incurred and expensed in prior periods. Fourth quarter of 2009 credits to income for environmental investigatory and remedial activities were $31.2 million and included $37.0 million of pretax recoveries for environmental costs incurred and expensed in prior periods. Without these recoveries, charges to income for environmental investigatory and remedial activities would have been $1.6 million in the fourth quarter of 2010 compared to $5.8 million in the fourth quarter of 2009. These charges relate primarily to remedial and investigatory activities associated with former waste sites and past operations.

Other corporate and unallocated costs in the fourth quarter of 2010 decreased $2.3 million compared to the fourth quarter of 2009, primarily due to lower asset retirement and legacy site costs, and lower salary and benefit costs, partially offset by higher legal and legal-related costs.

INCOME TAX EXPENSE

Fourth quarter 2010 income tax expense included $2.5 million of favorable adjustments primarily associated with the release of a portion of a valuation allowance recorded against the foreign tax loss carry forward deferred tax asset generated by the Canadian operations. Full year 2010 income tax expense included $13.5 million of favorable adjustments associated with the expiration of statutes of limitation and the release of the valuation allowance recorded against the foreign tax loss carryforward deferred tax asset.

FINANCING

During the fourth quarter of 2010, $153.0 million of variable rate Go Zone and Recovery Zone bonds were issued with final maturities of between 2024 and 2035. At December 31, 2010, $117.0 million of these bonds had been drawn and $102.0 million of the associated cash was classified as a restricted long-term asset. The restricted cash is required to be used to fund capital projects in Alabama, Mississippi and Tennessee.

DIVIDEND

Today, Olin's Board of Directors declared a dividend of $0.20 on each share of Olin common stock. The dividend is payable on March 10, 2011 to shareholders of record at the close of business on February 10, 2011. This is the 337th consecutive quarterly dividend to be paid by the Company.

        paper, and the migration by United States customers to low-cost foreign
        locations;
    --  the cyclical nature of our operating results, particularly declines in
        average selling prices in the chlor alkali industry and the
        supply/demand balance for our products, including the impact of excess
        industry capacity or an imbalance in demand for our chlor alkali
        products;
    --  economic and industry downturns that result in diminished product demand
        and excess manufacturing capacity in any of our segments and that, in
        many cases, result in lower selling prices and profits;
    --  costs and other expenditures in excess of those projected for
        environmental investigation and remediation or other legal proceedings;
    --  changes in legislation or government regulations or policies;
    --  unexpected litigation outcomes;
    --  new regulations or public policy changes regarding the transportation of
        hazardous chemicals and the security of chemical manufacturing
        facilities;
    --  the occurrence of unexpected manufacturing interruptions and outages,
        including those occurring as a result of labor disruptions and
        production hazards;
    --  higher-than-expected raw material and energy, transportation, and/or
        logistics costs;
    --  weak industry conditions could affect our ability to comply with the
        financial maintenance covenants in our senior revolving credit facility;
    --  the effects of any declines in global equity markets on asset values and
        any declines in interest rates used to value the liabilities in our
        pension plan;
    --  an increase in our indebtedness or higher-than-expected interest rates,
        affecting our ability to generate sufficient cash flow for debt service;
        and
    --  adverse conditions in the credit and capital markets, limiting or
        preventing our ability to borrow or raise capital.

All of our forward-looking statements should be considered in light of these factors. In addition, other risks and uncertainties not presently known to us or that we consider immaterial could affect the accuracy of our forward-looking statements.
