Fair Value Disclosures [Text Block]	NOTE 10—FAIR The Partnership determines the fair value of assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The fair values are based on assumptions that market participants would use when pricing an asset or liability, including assumptions about risk and the risks inherent in valuation techniques and the inputs to valuations. The fair value hierarchy is based on whether the inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources (including LIBOR-based discount rates), while unobservable inputs reflect the Partnership’s own assumptions of what market participants would use. The fair value hierarchy includes three may Level One - Quoted prices for identical instruments in active markets. Level Two - The fair value of the assets and liabilities included in Level 2 Level Three - Unobservable inputs significant to the fair value measurement supported by little or no third third third In those cases when the inputs used to measure fair value meet the definition of more than one The following methods and assumptions were used to estimate the fair value for which the fair value option was not Long-term debt: The carrying amounts and fair values of financial instruments for which the fair value option was not September 30, 2020 December 31, 2019 Carrying Fair Carrying Fair Amount Value Amount Value Affiliated Company Credit Agreement—Related Party $ 174,685 $ 157,217 $ 180,925 $ 180,925 The Partnership’s debt obligations are valued through reference to the applicable underlying benchmark rate and, as a result, constitute Level 2
