New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Standards	We elected the package of practical expedients permitted under the transition guidance within the new standard, which allowed us to carry forward our historical lease classification. We also elected the practical expedient related to land easements, which allowed us to carry forward our accounting treatment for land easements on existing leases. In addition we elected the hindsight practical expedient which resulted in increasing the length of our lease term for existing leases with cancellation provisions.
