for 2006 , without the cash due to replacement of fire-damaged assets , what would free cash flow have been , in millions?
cash flows from operating activities in 2006 were negatively affected by higher cash pension funding and higher working capital levels compared to the prior year . the higher working capital was a combination of higher than planned raw material inventory levels , higher income tax payments and higher accounts receivable balances , the latter resulting primarily from the repayment of a portion of the accounts receivable securitization program and late payments from customers in europe . management expects the increase in working capital to be temporary and that working capital levels will return to normal levels by the end of the first half of 2007. .
