[2] The Company utilizes the market approach valuation technique for its Level 3 fair value measures. Inputs to such measures could include observable market data obtained from independent sources such as broker quotes and recent market transactions for similar assets. It is the Company’s policy to maximize the use of observable inputs in the measurement of its Level 3 fair value measurements. To the extent observable inputs are not available, the Company utilizes unobservable inputs based upon the assumptions market participants would use in valuing the liability. Examples of utilized unobservable inputs are future cash flows and long-term growth rates.
