Business Context and Reporting Period

Company: Olin Corporation
Filing Type: Form 10-K (Annual Report)
Period Ended: December 31, 2005
Business Overview: Olin is a manufacturer operating in three primary segments: Chlor Alkali Products (26% of sales), Metals (59% of sales), and Winchester (15% of sales). The company is a major U.S. producer of chlorine, caustic soda, copper alloys, and sporting/military ammunition.

Key Financial Metrics

Segment Performance (Income before taxes):
- Chlor Alkali Products: $237.0 million (2005) vs. $83.0 million (2004).
- Metals: $34.0 million (2005) vs. $50.5 million (2004).
- Winchester: $7.8 million (2005) vs. $21.9 million (2004).

Material Changes vs. Prior Period

• Revenue Growth: Sales increased 18% to $2.36 billion, driven primarily by a 52% increase in Electrochemical Unit (ECU) selling prices in the Chlor Alkali segment and a 30% rise in copper prices in the Metals segment.
• Profitability Surge: Net income more than doubled to $133.3 million. Gross margin improved to 15% of sales from 12% in 2004.
• Environmental Recoveries: The company recovered $49.9 million from third parties for environmental costs incurred in prior periods, significantly boosting operating income and cash flow.
• Segment Divergence: While Chlor Alkali income surged due to pricing power, Metals income declined 33% due to lower volumes and higher costs. Winchester income dropped 64% due to rising raw material costs (copper, lead) and start-up costs at a new facility.
• Debt Reduction: Total debt decreased by approximately $54 million, and the debt-to-capitalization ratio improved from 47% to 38%.

Guidance, Outlook, and Risks

2006 Outlook

• Chlor Alkali: Management expects a stronger year in 2006 with further improvements in ECU netbacks and increased volumes in Q1.
• Metals Restructuring: The company plans to close the Waterbury Rolling Mills facility and consolidate operations. A one-time pretax charge of $25–$30 million is expected in Q1 2006, partially offset by $10 million in LIFO liquidation gains. Annual cost savings of $9–$12 million are projected.
• Winchester: Profitability is expected to improve as higher selling prices offset commodity costs. Military sales revenue is projected to increase 13%.
• Expenses: Pension expense is projected to be $12 million higher than 2005. Environmental charges are estimated in the $20 million range.

Key Risks and Contingencies

• Cyclicality: The Chlor Alkali industry is highly cyclical; profitability is sensitive to supply/demand imbalances and ECU pricing.
• Environmental Liabilities: The company has a $102.9 million reserve for environmental liabilities and estimates an additional $50 million in contingent liabilities. Future costs could be material.
• Pension Obligations: Significant unfunded pension liabilities exist. A $29.2 million non-cash charge to equity was recorded in 2005 due to lower interest rates and plan changes. No mandatory contributions are required until 2008.
• Raw Material Costs: Exposure to volatile prices for electricity, copper, lead, and natural gas.

Investor Verification Checklist

• Chlor Alkali Pricing Sustainability: Verify if the 52% increase in ECU netbacks is sustainable given the cyclical nature of the industry and potential new capacity additions post-2007.
• Environmental Reserve Adequacy: Assess the $102.9 million reserve against the disclosed $50 million in additional contingent liabilities and the history of cost overruns at remediation sites.
• Metals Restructuring Impact: Monitor the execution of the Waterbury closure and the realization of the projected $9–$12 million in annual cost savings.
• Pension Funding Status: Review the funded status of the pension plan and the impact of future interest rate changes on the $1.66 billion benefit obligation.
• Winchester Margin Recovery: Confirm if the segment can successfully pass through rising raw material costs to maintain margins in 2006.
