Fair Value Measurements |
Fair Value Measurements: | 6. Fair Value Measurements: The following methods and assumptions were used to estimate the fair value of each class of financial instruments: Cash and cash equivalents, trade accounts receivable, amounts due from/to related parties and trade accounts payable: The carrying values reported in the accompanying consolidated balance sheets for those financial instruments (except for the fair value of non-current portion of amounts due from related party) are reasonable estimates of their fair values due to their short-term nature. The carrying value of these instruments is separately reflected in the accompanying consolidated balance sheets. The fair value of non-current portion of amounts due from related party, determined through Level 3 inputs of the fair value hierarchy by discounting future cash flows using the Partnership’s estimated cost of capital, is $1,174 as of December 31, 2017, compared to its carrying value of $1,350. Long-term debt: The Term Loan B discussed in Note 5 approximates its recorded value due to the variable interest rate payable. The Notes have a fixed rate and their estimated fair value, determined through Level 2 inputs of the fair value hierarchy (quoted price in over-the-counter market), is approximately $253.1 million as of December 31, 2017, compared to its carrying value of $250.0 million. A fair value hierarchy that prioritizes the inputs used to measure fair value has been established by Generally Accepted Accounting Principles. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2: Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data; Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
