FAIR VALUE MEASUREMENTS
NOTE 15. FAIR VALUE MEASUREMENTS

Fair value is based on 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. Certain assets and liabilities are presented in our financial statements at fair value. Assets and liabilities measured at fair value on a recurring basis may include derivative warrant and conversion liabilities.  Assets and liabilities measured at fair value on a non-recurring basis may include property. As of September 30, 2019, and December 31, 2018, no assets or liabilities were measured at fair value.

We assess the inputs used to measure fair value using a three-tier hierarchy based on the extent to which inputs used in measuring fair value are observable in the market:


Level 1 – inputs include quoted prices for identical instruments and are the most observable.

Level 2 – inputs include quoted prices for similar assets and observable inputs such as interest rates, currency exchange rates and yield curves.

Level 3 – inputs are not observable in the market and include management’s judgments about the assumptions market participants would use in pricing the asset or liability.

The fair value of cash and cash equivalents, accounts and other receivables and accounts payable approximates their carrying value due to their shorter maturities.  As of September 30, 2019, the fair values of our debt and finance lease liabilities approximated their carrying values, based on the current market rates for similar debt with similar maturities.  The fair value of our operating lease liabilities as of September 30, 2019, was approximately $0.3 million higher than their carrying values, based on the current market rates for similar debt with similar maturities (Level 3 measurement).
