None of TCM's derivative instruments were treated as hedges for accounting purposes and all were recorded in the Condensed Consolidated Balance Sheets at fair value with changes in fair value recorded in the Condensed Consolidated Statements of Operations and Comprehensive Loss, except those contracts for which TCM has elected to apply the normal purchases and normal sales scope exception.</font></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">TCM is exposed to credit loss when counterparties with which it has entered into derivative transactions are unable to pay. To reduce counterparty credit exposure, TCM deals primarily with large, credit-worthy financial institutions and companies and limits credit exposure to each. TCM believes the counterparties to the contracts to be credit-worthy entities, and therefore, TCM believes credit risk of counterparty non-performance is relatively low.</font></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The fair value of TCM's assets and liabilities measured at fair value on a recurring basis was immaterial to TCM's Condensed Consolidated Balance Sheets at </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">June&#160;30, 2013</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">December 31, 2012</font><font style="font-family:inherit;font-size:10pt;">.</font></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">For the three and </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">six months ended</font><font style="font-family:inherit;font-size:10pt;"> </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">June 30, 2013</font><font style="font-family:inherit;font-size:10pt;">, the impact of derivative instruments was immaterial to TCM's Condensed Consolidated Statements of Operations and Comprehensive Loss.</font></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">For the three and </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">six months ended</font><font style="font-family:inherit;font-size:10pt;"> </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">June&#160;30, 2012</font><font style="font-family:inherit;font-size:10pt;">, TCM recorded </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">$4.4 million</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">$3.0 million</font><font style="font-family:inherit;font-size:10pt;">, respectively, of losses within Loss on foreign exchange and </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">$1.9 million</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">$1.8 million</font><font style="font-family:inherit;font-size:10pt;">, respectively, of gains within Change in fair value of common stock purchase warrants in the Condensed Consolidated Statements of Operations and Comprehensive Loss.
