Concentration of Credit Risk

Concentration of Credit Risk

TCM is exposed to counterparty risk from its cash and cash equivalent balances and its reclamation deposits held by financial institutions and governmental entities. TCM monitors its positions with, and the credit quality of, the financial institutions and companies in which it invests its cash and cash equivalents and that hold its reclamation deposits. Counterparties to cash balances and its reclamation deposits, other than balances maintained in various bank operating accounts, are US and Canadian institutions and the US and Canadian governments.

TCM manages its credit risk from its accounts receivable through its collection activities. As of September 30, 2013, TCM had three customers who owed TCM more than $3.0 million and accounted for approximately 27.4% of total accounts and other receivables outstanding. Another eight customers had balances greater than $1.0 million but less than $3.0 million that accounted for approximately 25.8% of total accounts and other receivables. All of these customers were compliant with applicable credit terms and scheduled payment dates.

TCM's maximum counterparty and credit risk exposure is the carrying value of its cash and cash equivalents and accounts receivable. The carrying amounts of accounts receivable, accounts payable, accrued liabilities and fixed-rate debt, excluding the 2017 Notes, 2018 Notes, 2019 Notes and tMEDS, as discussed in Notes 9 and 11, approximated fair value as of September 30, 2013.
