Defined Contribution Pension and Other Postretirement Plans Disclosure [Abstract] |
Retirement Benefit Plans |
11. | Retirement Benefit Plans
Substantially all U.S. employees are covered by various retirement benefit plans, including defined benefit pension plans, post-retirement medical plans and defined contribution savings plans. Retirement benefits for eligible employees in foreign locations are funded principally through defined benefit plans, annuity or government programs. The total cost of benefits for our plans was $11,078, $11,131 and $11,231 in 2012, 2011 and 2010, respectively. We have a qualified, funded defined benefit retirement plan (the “U.S. Pension Plan”) in the U.S. covering certain current and retired employees. Plan benefits are based on the years of service and compensation during the highest five consecutive years of service in the final ten years of employment. No new participants have entered the plan since 2000. The plan has approximately 447 participants including 102 active employees as of December 31, 2012. We have a U.S. postretirement medical benefit plan (the “U.S. Retiree Plan”) to provide certain healthcare benefits for U.S. employees hired before January 1, 1999. Eligibility for those benefits is based upon a combination of years of service with Tennant and age upon retirement. Our defined contribution savings plan (“401(k)”) covers substantially all U.S. employees. Under this plan, we match up to 3% of the employee’s compensation in stock or cash to be invested per their election. Historically, matching contributions have been primarily funded by our ESOP Plan. However, as of December 31, 2009, all shares have been allocated. Starting in 2010, the matching contributions to the 401(k) are funded with cash. We also make a profit sharing contribution to the 401(k) plan for employees with more than one year of service in accordance with our Profit Sharing Plan. This contribution is based upon our financial performance and can be funded in the form of Tennant stock, cash or a combination of both. Expenses for the 401(k) plan were $6,226, $6,864 and $7,073 during 2012, 2011 and 2010, respectively. We have a U.S. nonqualified supplemental benefit plan (the “U.S. Nonqualified Plan”) to provide additional retirement benefits for certain employees whose benefits under our 401(k) plan or U.S. Pension Plan are limited by either the Employee Retirement Income Security Act or the Internal Revenue Code. We also have defined pension benefit plans in the United Kingdom and Germany (the “U.K. Pension Plan” and the “German Pension Plan”). The U.K. Pension Plan and German Pension Plan cover certain current and retired employees and both plans are closed to new participants. On March 23, 2010, the Patient Protection and Affordable Care Act (the “PPACA”) was signed into law, and, on March 30, 2010, the Health Care and Education Reconciliation Act of 2010 (the “HCERA” and, together with PPACA, the “Acts”), which makes various amendments to certain aspects of the PPACA, was signed into law. The Acts effectively change the tax treatment of federal subsidies paid to sponsors of retiree health benefit plans that provide prescription drug benefits that are at least actuarially equivalent to the corresponding benefits provided under Medicare Part D. Under the Acts, an employer’s income tax deduction for the costs of providing Medicare Part D-equivalent prescription drug benefits to retirees will be reduced by the amount of the federal subsidy beginning in 2013. Under U.S. GAAP, any impact from a change in tax law must be recognized in earnings in the period enacted regardless of the effective date. The Acts did not have a material impact on our financial position or results of operations. During 2012 we made a $15,000 discretionary contribution to the U.S. Pension Plan in addition to the minimum funding requirements for 2011 and 2012. We expect to contribute approximately $145 to our U.S. Nonqualified Plan, $904 to our U.S. Retiree Plan, $234 to our U.K. Pension Plan and $39 to our German Pension Plan in 2013. No contributions to the U.S. Pension Plan are expected to be required during 2013. Weighted-average asset allocations by asset category of the U.S. and U.K. Pension Plans as of December 31, 2012 are as follows:

The primary objective of our U.S. and U.K. Pension Plans is to meet retirement income commitments to plan participants at a reasonable cost to Tennant and to maintain a sound actuarially funded status. This objective is accomplished through growth of capital and safety of funds invested. The pension plan assets are invested in securities to achieve growth of capital over inflation through appreciation and accumulation and reinvestment of dividend and interest income. Investments are diversified to control risk. The target allocation for the U.S. Pension Plan is 60% equity and 40% debt securities. Equity securities within the U.S. Pension Plan do not include any direct investments in Tennant Company Common Stock. The U.K. Pension Plan is invested in an insurance contract with underlying investments primarily in equity and fixed income securities. Our German Pension Plan is unfunded, which is customary in that country. The expected return on assets assumption on the investment portfolios for the pension and other postretirement benefit plans is based on the long-term expected returns for the investment mix of assets currently in the portfolio. Management uses historic return trends of the asset portfolio combined with recent market conditions to estimate the future rate of return. Weighted-average assumptions used to determine benefit obligations as of December 31, are as follows:
| U.S. Pension Benefits |  | Non-U.S. Pension Benefits |  | Postretirement Medical Benefits
| 2012 |  | 2011 |  | 2012 |  | 2011 |  | 2012 |  | 2011
Discount rate | 3.79 | % |  | 4.39 | % |  | 4.41 | % |  | 4.94 | % |  | 3.27 | % |  | 4.20 | %

The discount rate is used to discount future benefit obligations back to today’s dollars. Our discount rates were determined based on high-quality fixed income investments. The resulting discount rates are consistent with the duration of plan liabilities. The Citigroup Above Median Yield Curve is used in determining the discount rate for the U.S. Plans. The accumulated benefit obligations as of December 31, for all defined benefit plans are as follows:
| 2012 |  | 2011
U.S. Pension Plans | $ | 46,907 |  |  | $ | 42,909 |
U.K. Pension Plan | 8,837 |  |  | 7,858 |
German Pension Plan | 878 |  |  | 652 |
Information for our plans with an accumulated benefit obligation in excess of plan assets as of December 31, is as follows:
| U.S. Pension Plans |  | Non-U.S. Plans
| 2012 |  | 2011 |  | 2012 |  | 2011
Projected benefit obligation | $ | 48,824 |  |  | $ | 44,280 |  |  | $ | 10,011 |  |  | $ | 8,775 |

Fair value of plan assets | 46,942 |  |  | 28,237 |  |  | 8,855 |  |  | 7,738 |
As of December 31, 2012 the U.S Nonqualified and the German Pension Plans had an accumulated benefit obligation in excess of plan assets. As of December 31, 2011, the U.S. Pension Plan, the U.S. Nonqualified, U.K. Pension and German Pension Plans had an accumulated benefit obligation in excess of plan assets. Assumed healthcare cost trend rates as of December 31, are as follows:
| 2012 |  | 2011
Healthcare cost trend rate assumption for the next year | 9.17 | % |  | 10.14 | %
Rate to which the cost trend rate is assumed to decline (the ultimate trend rate) | 5.00 | % |  | 5.00 | %
Year that the rate reaches the ultimate trend rate | 2031 |  |  | 2031 |
Assumed healthcare cost trend rates have a significant effect on the amounts reported for healthcare plans. To illustrate, a one-percentage-point change in assumed healthcare cost trends would have the following effects:
| 1-Percentage- Point Decrease |  | 1-Percentage- Point Increase
Effect on total of service and interest cost components | $ | (54 | ) |  | $ | 61 |
Effect on postretirement benefit obligation | $ | (1,076 | ) |  | $ | 1,227 |
