Accounting Policies [Abstract]

Significant estimates and assumptions used in the preparation of the accompanying consolidated financial statements include those related to: accruals for product warranty, deferred tax assets, self-insured risks, pension and postretirement benefit obligations, litigation and environmental matters, as well as the evaluation of long lived asset impairments and determination of stock based compensation.
