Accounting Policies [Abstract]

Estimated Useful Lives of Property, Plant and Equipment

Depreciation is computed using the straight-line method at rates based on the estimated useful lives of the various classes of assets. Depreciable finance lease assets and leasehold improvements are amortized on a straight-line basis over the shorter of the estimated useful lives of the assets or the lease term. The estimated useful lives are as follows:

	Range (in years)
Land improvements	1-25
Buildings and leasehold improvements	2-45
Machinery and equipment	1-22
Depreciable finance lease assets	2-120
