2.5. Fair value of financial instruments

We value our financial assets and liabilities on a recurring basis using the fair value hierarchy established in Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures.

ASC 820 describes three levels of inputs that may be used to measure fair value, as follows:

Level 1 input, which includes quoted prices in active markets for identical assets or liabilities.

Level 2 inputs, which include observable inputs other than Level 1 inputs, such as quoted prices for similar assets or liabilities; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability; and

Level 3 inputs, which include unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the underlying asset or liability. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing models, discounted cash flow methodologies or similar valuation techniques, as well as significant management judgment or estimation.

The carrying amounts of cash and accounts payable approximate their fair value because of the short-term nature of these instruments.
