Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments, Policy

Financial Assets and Liabilities

The following methods and assumptions were used in estimating the fair value amounts included in the disclosures for financial assets and liabilities, which are consistent with those disclosed in the 2016 Annual Report on Form 10-K:

Cash and Cash Equivalents: For cash and short-term financial assets, the carrying amount is a reasonable estimate of fair value due to the short maturity of those instruments.

Long-Term Debt: The estimated fair value of the Partnership's publicly traded debt is based on quoted market prices at September 30, 2017, and December 31, 2016. The fair market value of the debt that is not publicly traded is based on market prices of similar debt at September 30, 2017, and December 31, 2016. The carrying amount of the Partnership's variable-rate debt at September 30, 2017, and December 31, 2016, approximated fair value.
