Market Conditions Business climate is difficult, which we expect to continue for the next few quarters Q3 same store volume down 7% from Q2, with most of the decline in September October volume down 2% from September and average selling price per ton down 4% October results solidly profitable General slowdown across all markets that we serve, with some strength still seen in certain energy markets 8 18. Market Conditions contd November operating environments have deteriorated from October Mill price decreases have accelerated and are substantial, which has caused us to further reduce our prices to our customers resulting in lower gross profit margins Economic uncertainty and continuing expectations of further mill price declines has caused our customers to significantly reduce purchasing activity 9 19. Strong Cash Flow We are focused on reducing debt acquisitions on hold Lower pricing and demand reduces our working capital needs and generates significant cash flow $700 million outstanding (November 18, 2008) on our $1.1 billion unsecured credit facility Paid off $147 million in October Paid off $68 million in the first 18 days of November Net debt-to-capital ratio at September 30, 2008 was 48.1% We expect to continue to generate significant cash flow from operations as we further reduce our working capital0 20.
