Compensation and Retirement Disclosure [Abstract] |
Pension and Other Postretirement Benefits Disclosure | PENSION AND OTHER POSTRETIREMENT BENEFITS We have defined benefit pension plans that cover certain employees in the U.S., Germany, the UK and Canada. Pension benefits under defined benefit pension plans are based on years of service and, for certain plans, on average compensation for specified years preceding retirement. We fund pension costs in accordance with the funding requirements of the Employee Retirement Income Security Act of 1974 (ERISA), as amended, for U.S. plans and in accordance with local regulations or customs for non-U.S. plans. Beginning in 2017, the accrued benefit for all participants in the Kennametal Inc. Retirement Income Plan is frozen as the result of amendment. The majority of our defined benefit pension plans are closed to future participation. We have an Executive Retirement Plan for various executives and a Supplemental Executive Retirement Plan both of which have been closed to future participation on June 15, 2017 and July 26, 2006, respectively. We presently provide varying levels of postretirement health care and life insurance benefits to certain employees and retirees. Postretirement health care benefits are available to employees and their spouses retiring on or after age 55 with 10 or more years of service. Beginning with retirements on or after January 1, 1998, our portion of the costs of postretirement health care benefits is capped at 1996 levels. Beginning with retirements on or after January 1, 2009, we have no obligation to provide a company subsidy for retiree medical costs. Postretirement health and life benefits are closed to future participants as of December 31, 2016. We use a June 30 measurement date for all of our plans. Defined Benefit Pension Plans The funded status of our pension plans and amounts recognized in the consolidated balance sheets as of June 30 were as follows:

Prepaid pension benefits are included in other long-term assets. The assets of our U.S. and international defined benefit pension plans consist principally of capital stocks, corporate bonds and government securities. To the best of our knowledge and belief, the asset portfolios of our defined benefit pension plans do not contain our capital stock. We do not issue insurance contracts to cover future annual benefits of defined benefit pension plan participants. Transactions between us and our defined benefit pension plans include the reimbursement of plan expenditures incurred by us on behalf of the plans. To the best of our knowledge and belief, the reimbursement of cost is permissible under current ERISA rules or local government law. The accumulated benefit obligation for all defined benefit pension plans was $940.9 million and $1,003.5 million as of June 30, 2017 and 2016, respectively.

The amount of accumulated other comprehensive income expected to be recognized in net periodic pension cost during 2018 related to prior service credit is less than $0.1 million. We expect to contribute approximately $1.9 million to our postretirement benefit plans in 2018. Assumptions The significant actuarial assumptions used to determine the present value of net benefit obligations for our defined benefit pension plans and other postretirement benefit plans were as follows:
| 2017 |  | 2016 |  | 2015
Discount Rate: |  |  |  |  |
U.S. plans | 3.3-3.9% |  |  | 2.4-3.7% |  | 3.2-4.5%
International plans | 2.0-3.3% |  |  | 0.9-3.2% |  | 2.3-3.8%
Rates of future salary increases: |  |  |  |  |
U.S. plans | 4.0 | % |  | 3.0-4.0% |  | 3.0-4.0%
International plans | 2.5-3.0% |  |  | 2.5-3.0% |  | 2.5-3.0%
The significant assumptions used to determine the net periodic (income) cost for our pension and other postretirement benefit plans were as follows:
| 2017 |  | 2016 |  | 2015
Discount Rate: |  |  |  |  |
U.S. plans | 2.4-3.7% |  |  | 3.2-4.5% |  |  | 4.4 | %
International plans | 0.9-3.2% |  |  | 2.3-3.8% |  |  | 2.9-4.3% |
Rates of future salary increases: |  |  |  |  |
U.S. plans | 3.0-4.0% |  |  | 3.0-4.0% |  |  | 3.0-5.0% |
International plans | 2.5-3.0% |  |  | 2.5-3.0% |  |  | 2.5-3.0% |
Rate of return on plans assets: |  |  |  |  |
U.S. plans | 7.5 | % |  | 7.5 | % |  | 7.5 | %
International plans | 5.3-5.5% |  |  | 5.3-5.5% |  |  | 5.0-6.0% |
The rates of return on plan assets are based on historical performance, as well as future expected returns by asset class considering macroeconomic conditions, current portfolio mix, long-term investment strategy and other available relevant information. The annual assumed rate of increase in the per capita cost of covered benefits (the health care cost trend rate) for our postretirement benefit plans was as follows:
| 2017 |  | 2016 |  | 2015
Health care costs trend rate assumed for next year | 8.0 | % |  | 8.5 | % |  | 7.3 | %
Rate to which the cost trend rate gradually declines | 5.0 | % |  | 5.0 | % |  | 5.0 | %
Year that the rate reaches the rate at which it is assumed to remain | 2027 |  |  | 2027 |  |  | 2024 |
A change of one percentage point in the assumed health care cost trend rates would have the following effects on the total service and interest cost components of our other postretirement cost and other postretirement benefit obligation at June 30, 2017:
(in thousands) | 1% Increase |  | 1% Decrease
Effect on total service and interest cost components | $ | 30 |  |  | $ | (27 | )
Effect on other postretirement obligation | 735 |  |  | (655 | )
Plan Assets The primary objective of certain of our pension plans' investment policies is to ensure that sufficient assets are available to provide the benefit obligations at the time the obligations come due. The overall investment strategy for the defined benefit pension plans' assets combine considerations of preservation of principal and moderate risk-taking. The assumption of an acceptable level of risk is warranted in order to achieve satisfactory results consistent with the long-term objectives of the portfolio. Fixed income securities comprise a significant portion of the portfolio due to their plan-liability-matching characteristics and to address the plans' cash flow requirements. Additionally, diversification of investments within each asset class is utilized to further reduce the impact of losses in single investments. Investment management practices must comply with ERISA and all applicable regulations and rulings thereof. The use of derivative instruments is permitted where appropriate and necessary for achieving overall investment policy objectives. Currently, the use of derivative instruments is not significant when compared to the overall investment portfolio. The Company utilizes a liability driven investment strategy (LDI) for the assets of its U.S. defined benefit pension plans in order to reduce the volatility of the funded status of these plans and to meet the obligations at an acceptable cost over the long term. This LDI strategy entails modifying the asset allocation and duration of the assets of the plans to more closely match the liability profile of these plans. The asset reallocation involves increasing the fixed income allocation, reducing the equity component and adding alternative investments. Longer duration interest rate swaps have been utilized periodically in order to increase the overall duration of the asset portfolio to more closely match the liabilities. Our defined benefit pension plans’ asset allocations as of June 30, 2017 and 2016 and target allocations for 2018, by asset class, were as follows:
| 2017 |  | 2016 |  | Target %
Equity | 27 | % |  | 23 | % |  | 22.5 | %
Fixed Income | 63 | % |  | 67 | % |  | 70.0 | %
Other | 10 | % |  | 10 | % |  | 7.5 | %
The following sections describe the valuation methodologies used by the trustee to measure the fair value of the defined benefit pension plan assets, including an indication of the level in the fair value hierarchy in which each type of asset is generally classified (see Note 5 for the definition of fair value and a description of the fair value hierarchy). Corporate fixed income securities Investments in corporate fixed income securities consist of corporate debt and asset backed securities. These investments are classified as level two and are valued using independent observable market inputs such as the treasury curve, swap curve and yield curve. Common stock Common stocks are classified as level one and are valued at their quoted market price. Government securities Investments in government securities consist of fixed income securities such as U.S. government and agency obligations and foreign government bonds and asset and mortgage backed securities such as obligations issued by government sponsored organizations. These investments are classified as level two and are valued using independent observable market inputs such as the treasury curve, credit spreads and interest rates. Other fixed income securities Investments in other fixed income securities are classified as level two and valued based on observable market data. Other Other investments consist primarily of a hedge fund, in addition to state and local obligations and short term investments including cash, corporate notes, and various short term debt instruments which can be redeemed within a nominal redemption notice period. These investments are primarily classified as level two and are valued using independent observable market inputs. The fair value methods described may not be reflective of future fair values. Additionally, while the Company believes the valuation methods used by the plans’ trustee are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in different fair value measurement at the reporting date. The following table presents the fair value of the benefit plan assets by asset category as of June 30, 2017:

(3) Investments in common / collective trusts invest primarily in publicly traded securities and are valued using net asset value (NAV) of units of a bank collective trust. Therefore, these amounts have not been classified in the fair value hierarchy and are presented in the tables to reconcile the fair value hierarchy to the total fair value of plan assets. Defined Contribution Plans We sponsor several defined contribution retirement plans. Costs for defined contribution plans were $15.8 million, $17.2 million and $23.1 million in 2017, 2016 and 2015, respectively.
