Fair Value Disclosures [Abstract] |
FAIR VALUE MEASUREMENTS | FAIR VALUE MEASUREMENTS Pursuant to the accounting guidance for fair value measurements and its subsequent updates, fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market and it considers assumptions that market participants would use when pricing the asset or liability. The accounting guidance for fair value measurement also specifies a hierarchy of valuation techniques based upon whether the inputs to those valuation techniques reflect assumptions other market participants would use based upon market data obtained from independent sources (observable inputs) or reflect the company's own assumption of market participant valuation (unobservable inputs). The fair value hierarchy consists of the following three levels:
• | Level 1 – Inputs are quoted prices in active markets for identical assets or liabilities.
• | Level 2 – Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.
• | Level 3 – Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.
Money market funds classified within Level 2 because they are not actively traded, have been valued using quoted market prices or alternative pricing sources and models utilizing observable market inputs. The following table presents the Company's financial assets that are measured at fair value on a recurring basis as of December 31, 2017 and January 1, 2017 consistent with the fair value hierarchy provisions of the authoritative guidance (in thousands):
