Fair Value Measurements
FAIR VALUE MEASUREMENTS
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Three levels of inputs may be used to measure fair value:
Level 1:
Valuations based on quoted prices in active markets for identical assets and liabilities.
Level 2:
Valuations based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.
Level 3:
Valuations based on unobservable inputs in which there is little or no market data available, which require the reporting entity to develop its own assumptions.
The following table presents information about our assets measured at fair value on a recurring basis in the condensed consolidated balance sheets as of June 30, 2017 and December 31, 2016:

We primarily use the market approach to determine the fair value of our financial assets. The fair value of our current assets and liabilities, including accounts receivable and accounts payable approximates the carrying value due to the short-term nature of these balances. We have currently chosen not to elect the fair value option for any items that are not already required to be measured at fair value in accordance with U.S. GAAP.
