Environmental Exit Costs by Cost [Table Text Block] The following table reflects the amounts of accrued liabilities recorded in our consolidated balance sheets related to environmental matters that are considered to be probable and reasonably estimable. Currently, we are not able to estimate possible losses or a range of possible losses in excess of amounts accrued. Except for matters discussed above, we do not
have any material environmental matters assessed as reasonably possible that would require disclosure in our consolidated financial statements.
