Fair Value Of Financial Instruments
Fair Value of Financial Instruments
ASC Topic 820, Fair Value Measurements and Disclosures, defines fair value and provides a hierarchal framework associated with the level of subjectivity used in measuring assets and liabilities at fair value.
At March 31, 2014 and December 31, 2013, our financial instruments consist primarily of cash, restricted cash, trade receivables, trade payables, and long-term debt. The carrying value of cash, restricted cash, trade and other receivables and trade payables are considered to be representative of their respective fair values due to the short-term nature of these instruments.
The fair value of our long-term debt is estimated using a discounted cash flow analysis, based on rates that we believe we would currently pay for similar types of debt instruments. This discounted cash flow analysis is based on inputs defined by ASC Topic 820 as level 2 inputs, which are observable inputs for similar types of debt instruments. The following table presents the supplemental fair value information about long-term debt at March 31, 2014 and December 31, 2013 (amounts in thousands):
