Disclosure of Fair Value Measurement of Assets | In the table below, we have segregated our financial assets and liabilities that are measured at fair value, based on the inputs used to determine fair value at the measurement date. The three levels within the fair value hierarchy, based on the reliability of inputs, are as follows: • Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities; • Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability either directly (i.e. prices) or indirectly (i.e. derived from prices); and • Level 3 inputs are inputs for the asset or liability that are not based on observable market data (i.e. unobservable inputs).
