The credit facilities mature on June 27, 2015 and are secured by a general charge over the assets of Superior and certain of its subsidiaries. As at December 31, 2012, Superior had $31.3 million of outstanding letters of credit (December 31, 2011 - $34.8 million) and approximately $121.9 million of outstanding financial guarantees (December 31, 2011 - $84.2 million). The fair value of Superior's revolving term bank credits, other debt, letters of credit, and financial guarantees approximates their carrying value as a result of the market based-interest rates, the short-term nature of the underlying debt instruments and other related factors.(2) Senior secured notes (the Notes) totalling US$92.0 million and US$124.0 million (respectively, CDN$126.1 million at December 31, 2012 and CDN $126.1 million at December 31, 2011) are secured by a general charge over the assets of Superior and certain of its subsidiaries. Principal repayments began in the fourth quarter of 2009. Management has estimated the fair value of the Notes based on comparisons to treasury instruments with similar maturities, interest rates and credit risk profiles. The estimated fair value of the Notes as at December 31, 2012 was CDN$94.4 million (December 31, 2011 - CDN$121.1 million).
