6. Financial Instruments
The composition of financial instruments is as follows:
The fair values of the Company’s financial instrument is the amount that would be received in an asset sale or paid to transfer a liability in an orderly transaction between unaffiliated market participants and is recorded using a hierarchical disclosure framework based upon the level of subjectivity of the inputs used in measuring assets and liabilities. The levels are described below:
Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data. Level 3: Unobservable inputs are used when little or no market data is available.
The Company classifies its financial instrument within Level 2 of the fair value hierarchy on the basis of models utilizing market observable inputs. The interest rate swap has been valued on the basis of valuations provided by third-party pricing services, as derived from standard valuation or pricing models. Market-based observable inputs for the interest rate swap include one month LIBOR-based yield curves over the term of the swap. The Company reviews third-party pricing provider models, key inputs and assumptions and understands the pricing processes at its third-party providers in determining the overall reasonableness of the fair value of its Level 2 financial instruments. The Company also considers the risk of nonperformance by assessing the swap counterparty's credit risk in the estimate of fair value of the interest rate swap. As of December 31, 2019 and 2018, the Company has not made any adjustments to the valuations obtained from its third party pricing providers.
