Fair Value
At December 31, 2012 and 2011, the fair value of the Company’s notes receivable approximated the cost basis. Fair value was calculated by discounting future cash flows from the notes receivable at estimated rates in which similar loans would have been made at December 31, 2012 and 2011. The estimate of the rate, which is the most significant input in the discounted cash flow calculation, is intended to replicate debt of similar type and maturity. This fair value calculation is considered to be a Level 3 calculation under the accounting guidelines, as the Company utilizes internally generated assumptions regarding current interest rates at which similar instruments would be executed.
