Defined Benefit Plans and Other Postretirement Benefit Plans Disclosures [Abstract]  
Retirement Benefit Plans
Retirement Benefit Plans
Defined Benefit Plans: The Company maintains various defined benefit pension plans that provide benefits based on years of service and average compensation during certain periods. The Company's policy is to make contributions to fund these plans within the range allowed by applicable regulations. Plan assets consist primarily of publicly traded stocks and government and corporate bonds.
Pension benefits are frozen for all employees other than certain NACoal unconsolidated mine employees. All other eligible employees of the Company, including employees whose pension benefits are frozen, receive retirement benefits under defined contribution retirement plans.
The assumptions used in accounting for the defined benefit plans were as follows for the years ended December 31:

The prior service credit and actuarial loss included in accumulated other comprehensive income (loss) expected to be recognized in net periodic benefit cost in 2013 are $0.1 million (less than $0.1 million net of tax) and $2.5 million ($1.6 million net of tax), respectively. No transition obligation is expected to be recognized in net periodic benefit cost in 2013.
The projected benefit obligation included in the table above represents the actuarial present value of benefits attributable to employee service rendered to date, including the effects of estimated future pay increases. The accumulated benefit obligation also reflects the actuarial present value of benefits attributable to employee service rendered to date, but does not include the effects of estimated future pay increases.
The Company does not expect to contribute to its U.S. or non-U.S. pension plans in 2013.
The Company maintains one supplemental defined benefit plan that pays monthly benefits to participants directly out of corporate funds. All other pension benefit payments are made from assets of the pension plans.
Future pension benefit payments expected to be paid from assets of the pension plans are:

The expected long-term rate of return on defined benefit plan assets reflects management's expectations of long-term rates of return on funds invested to provide for benefits included in the projected benefit obligations. In establishing the expected long-term rate of return assumption for plan assets, the Company considers the historical rates of return over a period of time that is consistent with the long-term nature of the underlying obligations of these plans as well as a forward-looking rate of return. The historical and forward-looking rates of return for each of the asset classes used to determine the Company's estimated rate of return assumption were based upon the rates of return earned or expected to be earned by investments in the equivalent benchmark market indices for each of the asset classes.
Expected returns for pension plans are based on a calculated market-related value of assets. Under this methodology, asset gains and losses resulting from actual returns that differ from the Company's expected returns are recognized in the market-related value of assets ratably over three years.
The pension plans maintain an investment policy that, among other things, establishes a portfolio asset allocation methodology with percentage allocation bands for individual asset classes. The investment policy provides that investments are reallocated between asset classes as balances exceed or fall below the appropriate allocation bands.

The defined benefit pension plans do not have any direct ownership of NACCO common stock.
The fair value of each major category of U.S. plan assets for the Company's pension plans are valued using quoted market prices in active markets for identical assets, or Level 1 in the fair value hierarchy. The fair value of each major category of Non-U.S. plan assets for the Company's pension plans are valued using observable inputs, either directly or indirectly, other than quoted market prices in active markets for identical assets, or Level 2 in the fair value hierarchy. Following are the values as of December 31:

Postretirement Health Care and Life Insurance: The Company also maintains health care plans which provide benefits to eligible retired employees. All health care plans of the Company have a cap on the Company's share of the costs. These plans have no assets. Under the Company's current policy, plan benefits are funded at the time they are due to participants. Effective June 30, 2010, the parent company eliminated its subsidized retiree medical plan. Effective September 1, 2010, HBB eliminated its retiree life insurance plan and the Company no longer maintains any retiree life insurance plans.

Each year, the assumptions used to calculate the benefit obligation are used to calculate the net periodic benefit cost for the following year.
Assumed health care cost trend rates can have a significant effect on the amounts reported for the health care plans. A one-percentage-point change in the assumed health care cost trend rates would have the following effects at December 31, 2012:

Defined Contribution Plans: NACCO and its subsidiaries have defined contribution (401(k)) plans for substantially all U.S. employees and similar plans for employees outside of the United States. For NACCO and those subsidiaries, other than HBB, the applicable company matches employee contributions based on plan provisions. In addition, NACCO and certain other subsidiaries have defined contribution retirement plans that generally provide for a stated minimum employer contribution. These plans also permit additional contributions whereby the applicable company's contribution to participants is determined annually based on a formula that includes the effect of actual compared with targeted operating results and the age and compensation of the participants. Total costs, including Company contributions, for these plans were $6.7 million, $5.3 million and $6.6 million in 2012, 2011 and 2010, respectively.
