14. Financial Instruments

The carrying amounts of financial instruments, including cash and cash equivalents, accounts receivable and accounts payable approximated their fair value as of December 31, 2018 and 2017, because of the relative short maturity of these instruments.

“Fair Value Measurements and Disclosures” defines fair value as the 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 on the measurement date.

The accounting standard establishes a fair value hierarchy that prioritizes the inputs used to measure fair value into three levels. The three levels are defined as follows:

      Level 1: Unadjusted quoted price in active market for identical assets and liabilities.

      Level 2: Observable inputs other than those included in Level 1.

      Level 3: Unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability.
