Accounting Policies [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements: In June 2016, the FASB issued Accounting Standards Update (ASU) 2016-13, Financial Instruments – Credit Losses. This ASU makes changes to the impairment model for trade receivables, net investments in leases, debt securities, loans and certain other instruments. The standard requires the use of a forward-looking "expected loss" model compared to the current "incurred loss" model. We expect to adopt this ASU in the first quarter of 2020 when the standard becomes effective. We continue to evaluate this ASU but do not believe it will have a material impact on our Consolidated Financial Statements.
