Employee Benefits Deferred compensation         TCM maintains an employee deferred compensation program for certain individuals, the majority of whom were employed at the time of the acquisition of Thompson Creek USA. TCM recognizes a liability for the future obligation associated with the program, and the cost is charged as an expense during the period according to the payment formula, which is based on the employee's compensation and discounted for the estimated present value of the obligation. As of December 31, 2010, and 2009 TCM recorded a liability of $16.5 million and $17.0 million, respectively, related to this program, which are included in other liabilities. As of December 31, 2010, $8.9 million of the obligation is payable in June 2012, or earlier under certain conditions according to the provisions of the program. The remaining obligation is payable upon reaching a certain age requirement or earlier according to the provisions of the program. TCM has set aside funding for this liability by making periodic contributions to a trust fund based upon program participants' salaries. The trust fund assets as of December 31, 2010, and 2009 totaled $19.8 million and $16.8 million, respectively, and the trust has been consolidated. For the years ended December 31, 2010, 2009, and 2008, TCM recognized an expense of $0.6 million, $3.9 million, and $4.9 million, respectively, for the deferred compensation program. The 2010 expense was net of an out-of-period adjustment of $3.4 million ($2.1 million net of tax effect) that was recorded to adjust the liability to present value. Management does not believe that this adjustment is material to any of the periods affected or presented in its consolidated financial statements. Defined Contribution Pension Plans         TCM, through its subsidiaries, maintains defined contribution pension plans available to certain employees. TCM's 401(k) Savings Plan (the "Plan") is a defined contribution pension plan and covers all individuals employed in the US. The Plan is subject to the provisions of the US Employee Retirement Income Security Act of 1974, as amended, and Section 401(k) of the US Internal Revenue Code. The assets of the Plan are held and the related investment transactions are executed by the Plan's trustee. Administrative fees, including accounting and attorney fees, are paid by TCM on behalf of the Plan. TCM contributed approximately $1.2 million, $1.7 million, and $1.5 million, respectively, to the Plan for the years ended December 31, 2010, 2009 and 2008. TCM may make additional contributions to the Plan at its sole discretion; however, TCM has no further obligation relating to benefits under this Plan.         The Endako Mine maintains a defined contribution pension plan (the "Endako Plan") covering all of its employees. The assets of the Endako Plan are held and the related investment transactions are executed by the Endako Plan's trustee. Administrative fees, including any accounting and legal fees are paid by the Endako Mine on behalf of the Endako Plan. The Endako Mine contributed $0.9 million, $0.7 million and $0.8 million to the Endako Plan for the years ended December 31, 2010, 2009 and 2008, respectively. TCM has recorded its proportionate share of 75% related to these contributions. TCM has no further obligation relating to pension benefits under this Plan. Postretirement Benefits         Under the union agreement at the Langeloth facility, TCM is required to provide postretirement medical benefits for certain retired former employees and their dependants by making the monthly medical insurance premium payments on their behalf. Substantially all of TCM's current unionized employees may become eligible for this benefit if certain age and service requirements are met at the time of retirement, as specified in the union agreement. The benefit ceases when the eligible retired employee reaches 65 years of age. TCM does not have any obligation related to eligible retired unionized employees beyond the monthly medical insurance premiums. TCM follows current accounting guidance related to postretirement benefits for this plan. Prior service costs, actuarial gains and losses, and transition obligations are amortized over the average life expectancy of the plan's participants.         The following table sets forth the actuarial present value of postretirement medical benefit obligations and amounts recognized in TCM's financial statements: <div style="PADDING-RIGHT: 0pt; PADDING-LEFT: 0pt; PADDING-BOTTOM: 0pt; MARGIN-LEFT: 20%; WIDTH: 60%; PADDING-TOP: 0pt; POSITION: relative">   <div align="center"> <table cellspacing="0" cellpadding="0" width="100%" border="0"> <tr style="HEIGHT: 0px"> <td style="FONT-FAMILY: times" align="left"></td> <td style="FONT-FAMILY: times" width="12"></td> <td style="FONT-FAMILY: times" align="right" width="7"></td> <td style="FONT-FAMILY: times" width="64"></td> <td style="FONT-FAMILY: times" width="12"></td></tr> <tr style="HEIGHT: 0px" valign="bottom"> <th style="FONT-FAMILY: times" align="left">  </th> <th style="FONT-FAMILY: times"> </th> <th style="BORDER-BOTTOM: #000000 1pt solid; FONT-FAMILY: times" align="center" colspan="2">December 31, 2010 </th> <th style="FONT-FAMILY: times"> </th></tr> <tr style="HEIGHT: 0px" valign="top" bgcolor="#CCEEFF"> <td style="FONT-FAMILY: times" valign="bottom"> Change in benefit obligations:</td> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="FONT-FAMILY: times" valign="bottom"> </td></tr> <tr style="HEIGHT: 0px" valign="top" bgcolor="white"> <td style="FONT-FAMILY: times" valign="bottom"> Net benefit obligation at beginning of year</td> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="FONT-FAMILY: times" valign="bottom" align="right">$</td> <td style="FONT-FAMILY: times" valign="bottom" align="right">2.8</td> <td style="FONT-FAMILY: times" valign="bottom"> </td></tr> <tr style="HEIGHT: 0px" valign="top" bgcolor="#CCEEFF"> <td style="FONT-FAMILY: times" valign="bottom"> (Gain) loss</td> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="FONT-FAMILY: times" valign="bottom" align="right">(0.3</td> <td style="FONT-FAMILY: times" valign="bottom">)</td></tr> <tr style="HEIGHT: 0px" valign="top" bgcolor="white"> <td style="FONT-FAMILY: times" valign="bottom"> Service cost</td> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="FONT-FAMILY: times" valign="bottom" align="right">0.3</td> <td style="FONT-FAMILY: times" valign="bottom"> </td></tr> <tr style="HEIGHT: 0px" valign="top" bgcolor="#CCEEFF"> <td style="FONT-FAMILY: times" valign="bottom"> Interest cost</td> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="FONT-FAMILY: times" valign="bottom" align="right">0.1</td> <td style="FONT-FAMILY: times" valign="bottom"> </td></tr> <tr style="HEIGHT: 0px" valign="top" bgcolor="white"> <td style="FONT-FAMILY: times" valign="bottom"> Benefits paid</td> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="FONT-FAMILY: times" valign="bottom" align="right">(0.1</td> <td style="FONT-FAMILY: times" valign="bottom">)</td></tr> <tr style="FONT-SIZE: 1.5pt; HEIGHT: 0px" valign="top"> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="BORDER-BOTTOM: #000000 1pt solid; FONT-FAMILY: times" valign="bottom" align="right" colspan="2"> </td> <td style="FONT-FAMILY: times" valign="bottom"> </td></tr> <tr style="HEIGHT: 0px" valign="top" bgcolor="#CCEEFF"> <td style="FONT-FAMILY: times" valign="bottom">  </td> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="FONT-FAMILY: times" valign="bottom" align="right">$</td> <td style="FONT-FAMILY: times" valign="bottom" align="right">2.8</td> <td style="FONT-FAMILY: times" valign="bottom"> </td></tr> <tr style="FONT-SIZE: 1.5pt; HEIGHT: 0px" valign="top"> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="FONT-FAMILY: times" valign="bottom"> </td> <td style="BORDER-BOTTOM: #000000 2.25pt double; FONT-FAMILY: times" valign="bottom" align="right" colspan="2"> </td> <td style="FONT-FAMILY: times" valign="bottom"> </td></tr></table></div> </div>         The liability of $2.8 million has been included in other liabilities on the TCM's consolidated balance sheet as of December 31, 2010.         The assumptions used to determine the benefit obligations as of December 31, 2010, included a measurement date of December 31, 2010, and a discount rate of 5.75%. The yield curve matching TCM's benefit obligation was derived using a cash flow analysis under the Citigroup pension liability index. The Citigroup pension discount curve shows the relationship between interest rates and the duration for hypothetical zero coupon investments. This yield curve was used in determining the discount rate for TCM's postretirement benefit obligation.         The components of net periodic benefit costs for the year ended December 31, 2010 included $0.3 million of service cost and $0.1 million of interest cost for a total net periodic benefit cost of $0.4 million.         The health care cost trend assumed that average cost of coverage was 9.0% for 2010, reduced annually to an ultimate trend of 5.0% in 2016 and beyond. The assumed health care cost trend rates can have a significant effect on the amounts reported for postretirement medical benefits. The effect of a one percent change in the health care cost trend rate used to calculate periodic postretirement medical costs and the related benefit obligation would be insignificant to this benefit obligation.         The expected postretirement medical benefits expected to be paid in the next five fiscal years are insignificant to any individual year. </td></tr></table> 13.
