Fair Value Measurements |
Schedule of carrying value and fair value of the entity's financial instruments | The carrying value and fair value of our financial instruments as of June 30, 2013 and December 31, 2012 assuming election of fair value for our financial assets and financial liabilities were as follows (in thousands):
|  | At June 30, 2013 |  | At December 31, 2012 |
|  | Carrying Value |  | Fair Value |  | Carrying Value |  | Fair Value |
Mortgage loans receivable |  | $39,272 |  | $44,741(1) |  | $39,299 |  | $44,939(1) |
Bonds payable |  | 2,035 |  | 2,035(2) |  | 2,635 |  | 2,635(2) |
Bank borrowings |  | — |  | —(2) |  | 115,500 |  | 115,500(2) |
Senior unsecured notes |  | 185,800 |  | 190,841(3) |  | 185,800 |  | 194,838(3) |
Contingent liabilities |  | 6,963 |  | 6,963(4) |  | 6,744 |  | 6,744(4) |
(1) Our investment in mortgage loans receivable is classified as Level 3. The fair value is determined using a widely accepted valuation technique, discounted cash flow analysis on the expected cash flows. The discount rate is determined using our assumption on market conditions adjusted for market and credit risk and current returns on our investments. The discount rate used to value our future cash inflows of the mortgage loans receivable at June 30, 2013 and December 31, 2012 was 5.5% and 6.0%, respectively. (2) Our bonds payable and bank borrowings are at a variable interest rate. The estimated fair value of our bonds payable and bank borrowings approximated their carrying values at June 30, 2013 and December 31, 2012 based upon prevailing market interest rates for similar debt arrangements. (3) Our obligation under our senior unsecured notes is classified as Level 3 and thus the fair value is determined using a widely accepted valuation technique, discounted cash flow analysis on the expected cash flows. The discount rate is measured based upon management’s estimates of rates currently prevailing for comparable loans available to us, and instruments of comparable maturities. At June 30, 2013, the discount rate used to value our future cash outflow of our senior unsecured notes was 3.9% for those maturing before year 2019 and 4.6% for those maturing through year 2021. At December 31, 2012, the discount rate used to value our future cash outflow of our senior unsecured notes was 3.8% for those maturing before year 2019 and 4.3% for those maturing through year 2021. (4) Our contingent obligation under the earn-out liabilities is classified as Level 3. We estimated the fair value of the contingent earn-out payments using a discounted cash flow analysis. The discount rate that we use consists of a risk-free U.S. Treasury rate plus a company specific credit spread which we believe is acceptable by willing market participants. At June 30, 2013 and December 31, 2012, the discount rate used to value our future cash outflow of the earn-out liability was 6.2% and 6.6%, respectively.
