[1] The Company had a non-recurring fair value measurement for an intangible asset with a carrying amount of $84.9 million that was written down to its estimated fair value of $83.9 million resulting in an impairment charge of $993,000, which was included in earnings for December 31, 2013. The implied fair value was calculated using a discounted cash flow model that incorporated a wide range of assumptions including current asset pricing, price escalation, discount rates, absorption rates, timing of sales, and costs. Given the decline in market prices for similar assets, increases in interest rates, and extended timing of expected absorptions, the Company adjusted its assumptions and judgments in the model from original projections

[2] As of December 31, 2011, the Company had a non-recurring fair value measurement for an intangible asset with a carrying amount of $101.1 million that was written down to its implied fair value of $84.9 million, resulting in an impairment charge of $16.2 million, which was included in earnings for December 31, 2011. The implied fair value was calculated using a discounted cash flow model that incorporated a wide range of assumptions including current asset pricing, price escalation, discount rates, absorption rates, and timing of sales, and costs. Given the dramatic and prolonged slow-down in housing starts and sales in the North Valleys of Reno, Nevada, and the decline in market prices for similar assets, the Company adjusted its assumptions and judgments in the model by reducing the price and lengthening the timing of absorption of water sales from the original projections.
