Fair Value Disclosures [Abstract]
Fair Value Disclosures	5. FAIR VALUE DISCLOSURES The following methods, assumptions and valuation techniques were used to estimate the fair value of the partnership’s financial instruments: Level 1 – unadjusted quoted prices in active markets for identical assets or liabilities the partnership can access at the measurement date. Level 2 – directly or indirectly observable inputs such, as quoted prices for similar assets or liabilities in active markets other than quoted prices included within Level 1, quoted prices for identical or similar assets in markets that are not active, and other inputs that are observable or can be substantially corroborated by observable market data through correlation or other means. Level 3 – unobservable inputs that are supported by little or no market activity and comprise a significant component of the fair value of the assets or liabilities. The partnership currently does not have any recurring Level 3 financial instruments. The carrying amounts of financial assets and liabilities with maturities of less than one year, including cash and cash equivalents, accounts receivable and accounts payable, approximate fair value due to the short period to maturity. The partnership uses market interest rates to measure the fair value of its long‑term debt and adjusts those rates for all necessary risks, including its own credit risk. At December 31, 2017 and 2016, the carrying amount of debt approximated fair value.

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.
