9. Fair Value of Financial Instruments and Fair Value Measurements

ASC Subtopic 820-10, Fair Value Measurements and Disclosures, requires us to use valuation techniques to measure fair value that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized as follows:

Level 1: Observable inputs such as quoted prices for identical assets or liabilities in active markets.

Level 2: Other inputs that are observable directly or indirectly, such as quoted prices for similar assets or liabilities or market-corroborated inputs.

Level 3: Unobservable inputs for which there is little or no market data and which require us to develop our own assumptions about how market participants would price the assets or liabilities.

The carrying amounts of cash and cash equivalents, trade accounts receivable and accounts payable approximate fair value as of September 30, 2013 and December 31, 2012 because of the relatively short maturity of these instruments.

The redeemable convertible preferred stock and warrants were sold in an arms-length transaction on May 2, 2012. Accordingly, we believe the recorded values approximate fair values for these instruments at September 30, 2013.

As discussed in Note 5. Investment in Foreign Joint Ventures, the carrying values of these investments are reviewed quarterly to ascertain that they are not impaired.
