The following tables provide a reconciliation of the changes in the plans’ benefit obligations and fair value of assets over the two-year period ended December 31, 2012, and the funded status as of December 31, 2012 and December 31, 2011 (in thousands):

We also sponsor post-retirement term life insurance benefits for substantially all retirees who retire from active service. The accumulated post-retirement benefit obligation under all such plans totaled $1.9 million at December 31, 2012 and $1.6 million at December 31, 2011. We are indemnified by insurance carriers for all retiree term life coverage. The following table provides the amounts recognized in the consolidated balance sheets as of December 31, 2012 and December 31, 2011 (in thousands):
|  | Pension Benefits |  |  | Other Benefits |
|  | 2012 |  |  | 2011 |  |  | 2012 |  |  | 2011 |
Current liabilities: |  |  |  |  |  |  |  |  |  |  |  |

Net amount recognized |  | $ | 2,693 |  |  | $ | 7,933 |  |  | $ | (368 | ) |  | $ | (405 | )
The benefit obligation and prepaid benefit costs were calculated by applying the following weighted average assumptions:
|  | Pension Benefits |  |  | Other Benefits |
|  | 2012 |  |  | 2011 |  |  | 2012 |  |  | 2011 |
Discount rate: net periodic pension cost |  |  | 4.75 | % |  |  | 5.50 | % |  |  | — |  |  |  | — |
Discount rate: projected benefit obligation |  |  | 4.00 | % |  |  | 4.75 | % |  |  | 4.00 | % |  |  | 4.75 | %
Expected rate of return on plan assets |  |  | 7.20 | % |  |  | 8.00 | % |  |  | — |  |  |  | — |
Rate of compensation increase |  |  | 4.00 | % |  |  | 4.00 | % |  |  | — |  |  |  | — |
The above assumptions were calculated based on information as of December 31, 2012 and December 31, 2011, the measurement dates for the plans. The discount rate is based on the yield curve for investment-grade corporate bonds as published by the U.S. Treasury Department. The expected rate of return on plan assets is based upon consideration of the plan’s current asset mix, historical long-term return rates and the plan’s historical performance. Our current expected rate on plan assets of 7.2% is based on historical returns over the past ten years. Net periodic pension cost for the plans consisted of the following in 2012, 2011, and 2010 (in thousands):
|  | Pension Benefits |  |  | Other Benefits |
|  | 2012 |  |  | 2011 |  |  | 2010 |  |  | 2012 |  |  | 2011 |  |  | 2010 |

These investments represent approximately 4% of the total combined assets of these plans at both December 31, 2012 and December 31, 2011. Our statement of investment policy delineates the responsibilities of the board, the management investment committee, the investment manager(s), and investment adviser/consultant, and provides guidelines on investment management. Investment objectives are established for each of the asset categories included in the pension plans with comparisons of performance against appropriate benchmarks. Our policy calls for investments to be supervised by qualified investment managers. The investment managers are monitored on an ongoing basis by our outside consultant, with formal reporting to us and the consultant performed each quarter. The policy sets forth the following allocation of assets:
|  | Target |  |  | Minimum |  |  | Maximum |
Large cap U.S. equities |  |  | 10 | % |  |  | 7 | % |  |  | 13 | %

Our statement of investment policy and objectives aspires to achieve the assumed long term rate of return on plan assets established by the plan’s actuary plus one percent. Accounting guidance has established a hierarchy of assets measured at fair value on a recurring basis. The three levels included in the hierarchy are: Level 1: quoted prices in active markets for identical assets or liabilities Level 2: significant other observable inputs Level 3: significant unobservable inputs The fair values by asset category in each plan, along with their hierarchy levels, are as follows as of December 31, 2012 (in thousands):

Of the $16.9 million reported as level 3 assets above, $8.2 million was comprised of real estate funds, while the remainder was invested in common collective funds. Generally, investments are valued based on information provided by fund managers to our trustee as reviewed by management and its investment advisers. Mutual funds and equities are valued based on available exchange data. Commingled equity funds consist of publicly-traded investments. Fair value for real estate and private equity partnerships is primarily based on valuation methodologies that include third-party appraisals, comparable transactions, and discounted cash flow valuation models. Future benefit payments, which reflect expected future service as appropriate, are estimates of what will be paid in the following years (in thousands):

Amortization of prior service cost |  |  | 390 |  |  |  | — |
We do not expect to have any of the plans’ assets returned during 2013. Capital Accumulation Plans Our employees’ Capital Accumulation (401(k)) Plan is available to all U.S. salaried and certain hourly employees and applies immediately upon employment. Employees may contribute from 1% to 50% of their annual compensation to the plan (subject to statutory limits). We make a matching contribution of 100% of an employee’s contribution up to 6% of the employee’s earnings. Our matching contributions were approximately $2.5 million in 2012, $2.2 million in 2011, and $2.1 million in 2010. We also maintain an employees’ 401(k) plan, which is available to all hourly employees at the Lucky Friday unit after completion of six months of service. Employees may contribute from 2% to 50% of their compensation to the plan (subject to statutory limits). We make a matching contribution of 35% of an employee’s contribution up to 5% of the employee’s earnings. In May 2010, union contract negotiations resulted in a change to the matching contribution of 35%. Starting after May 10, 2010 the matching contribution is 55% of an employee’s contribution up to, but not exceeding, 5% of the employee’s earnings. Our contributions were approximately $407,000 in 2012, $246,000 in 2011, and $229,000 in 2010.
