S. putting us in a preferred position with regards to profitability 22 Winchester Products Products End Uses Winchester ® sporting ammunition -- shotshells, small caliber centerfire & rimfire ammunition Hunters & recreational shooters, law enforcement agencies Small caliber military ammunition Infantry and mounted weapons Industrial products -- 8 Maintenance applications in power & concrete gauge loads & powder- industries, powder-actuated tools in construction actuated tool loads industry 23 Winchester • Profits of $8.1 million reflect best first quarter ever • Nine price increases announced since the beginning of 2004 to offset higher metal prices • Continued increase in metal prices, especially lead, poses a challenge for 2007 • Winchester recently received 2 new military orders: 1. $18 million order from US Army for shotgun shells, and 2. $24 million order under General Dynamics second source small caliber ammunition program 24 Financial Highlights • Q1 cash and short-term investments of $283 million exceed outstanding debt by nearly $30 million • $15 million sale/leaseback, lower tax payments and lower level of working capital growth increased cash balances in Q1 which is normally a cash use period • $80 million voluntary pension contribution in Q3 2006 coupled with higher discount rate and healthy returns on plan assets cut funded status shortfall by $148 million to $234 million • $100 million voluntary contribution this quarter and investment policy change will likely lead to fully funded plan by 2011 without further contributions 25 Financial Highlights (continued) • 2007 pension expense expected to decrease by approximately $21 million as compared to 2006 • Favorably settled all IRS audits through 2002 resulting in a $22 million reduction in tax expense in 2006 • 2007 effective tax rate expected to be in the 34% to 35% range • Capital spending levels, net of January sale leaseback transaction, are expected to be $75 to $80 million in 2007 with 65% allocated to Chlor-Alkali to complete bleach expansion and ongoing maintenance projects 26 Investment Rationale • Continued strong performance based on – Relatively high ECU prices, Pioneer acquisition likely – Cost reductions, better pricing, inventory liquidation gains and restructuring in Metals – Cost reductions, price increases and increased U.S. Military revenue in Winchester • Strong financial discipline • Commitment to investment grade credit rating • At recent price levels, common dividend yield is approximately 4.00% • 322nd consecutive quarterly common dividend (80+ years) paid in June 27 Forward-Looking Statements This presentation contains estimates of future performance, which are forward-looking statements and actual results could differ materially from those anticipated in the forwardlooking statements.
