Pension and Postretirement Benefits | Note 18. Pension and Postretirement Benefits Domestic Plans. Viad has trusteed, frozen defined benefit pension plans that cover certain employees which are funded by the Company. Viad also maintains certain unfunded defined benefit pension plans which provide supplemental benefits to select management employees. These plans use traditional defined benefit formulas based on years of service and final average compensation. Funding policies provide that payments to defined benefit pension trusts shall be at least equal to the minimum funding required by applicable regulations. Viad also has certain defined benefit postretirement plans that provide medical and life insurance for certain eligible employees, retirees, and dependents. The related postretirement benefit liabilities are recognized over the period that services are provided by employees. In addition, Viad retained the obligations for these benefits for retirees of certain sold businesses. While the plans have no funding requirements, Viad may fund the plans. The components of net periodic benefit cost and other amounts recognized in other comprehensive income of Viad’s pension plans included the following:

The Viad Corp Medical Plan maintained a trust account for plan assets invested in various securities. In June 2014, the trust account was closed after all plan assets were liquidated to reimburse Viad Corp for net postretirement medical claims paid. All medical claims are being paid by Viad. Viad employs a total return investment approach whereby a mix of equities and fixed income securities is used to maximize the long-term return of plan assets for a prudent level of risk. Risk tolerance is established through careful consideration of plan liabilities, plan funded status, and corporate financial condition. The investment portfolio contains a diversified blend of equity and fixed income securities. Furthermore, equity securities are diversified across U.S. and non-U.S. stocks, as well as growth and value. Investment risk is measured and monitored on an ongoing basis through quarterly investment portfolio reviews and annual liability measurements. Viad utilizes a building-block approach in determining the long-term expected rate of return on plan assets. Historical markets are studied and long-term historical relationships between equity securities and fixed income securities are preserved consistent with the widely accepted capital market principle that assets with higher volatility generate a greater return over the long run. Current market factors such as inflation and interest rates are evaluated before long-term capital market assumptions are determined. The long-term portfolio return also considers diversification and rebalancing. Peer data and historical returns are reviewed relative to Viad’s assumed rates for reasonableness and appropriateness. The following pension and postretirement benefit payments, which reflect expected future service, as appropriate, are expected to be paid:
(in thousands) |  | Funded Plans |  |  | Unfunded Plans |  |  | Postretirement Benefit Plans |

Foreign Pension Plans. Certain of Viad’s foreign operations also maintain trusteed defined benefit pension plans covering certain employees which are funded by the companies, and unfunded defined benefit pension plans providing supplemental benefits to select management employees. These plans use traditional defined benefit formulas based on years of service and final average compensation. Funding policies provide that payments to defined benefit pension trusts shall be at least equal to the minimum funding required by applicable regulations.

In aggregate for both the domestic and foreign plans, the Company anticipates contributing $0.9 million to the funded pension plans, $0.8 million to the unfunded pension plans and $1.1 million to the postretirement benefit plans in 2016. Weighted-Average Assumptions. Weighted-average assumptions used to determine benefit obligations as of December 31 were as follows:
|  | Domestic Plans |  |  |  |  |  |  |  |  |

Weighted-average assumptions used to determine net periodic benefit cost were as follows:
|  | Domestic Plans |  |  |  |  |  |  |  |  |
|  | Funded Plans |  |  | Unfunded Plans |  |  | Postretirement Benefit Plans |  |  | Foreign Plans |

Expected return on plan assets |  |  | 3.33 | % |  |  | 4.15 | % |  | N/A |  |  | N/A |  |  |  | 0.00 | % |  |  | 0.00 | % |  |  | 4.51 | % |  |  | 5.69 | %

The assumed health care cost trend rate used in measuring the December 31, 2015 accumulated postretirement benefit obligation was 7.0 percent, declining one-quarter percent each year to the ultimate rate of 4.5 percent by the year 2025 and remaining at that level thereafter. The assumed health care cost trend rate used in measuring the December 31, 2014 accumulated postretirement benefit obligation was 7.5 percent, declining one-quarter percent each year to the ultimate rate of 5.0 percent by the year 2025 and remaining at that level thereafter. A one-percentage-point increase in the assumed health care cost trend rate for each year would increase the accumulated postretirement benefit obligation as of December 31, 2015 by approximately $1.5 million and the total of service and interest cost components by approximately $0.1 million. A one-percentage-point decrease in the assumed health care cost trend rate for each year would decrease the accumulated postretirement benefit obligation as of December 31, 2015 by approximately $1.3 million and the total of service and interest cost components by approximately $0.1 million. Multi-employer Plans. Viad contributes to defined benefit pension plans under the terms of collective-bargaining agreements that cover its union-represented employees. The financial risks of participating in these multi-employer pension plans generally include the fact that assets contributed to the plan by one employer may be used to provide benefits to employees of other participating employers. Furthermore, if a participating employer ceases to contribute to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. In addition, if Viad were to discontinue its participation in some of its multi-employer pension plans, the Company may be required to pay those plans a withdrawal liability amount based on the underfunded status of the plan. Viad also contributes to defined contribution plans pursuant to its collective-bargaining agreements, which are generally not subject to the funding risks inherent in defined benefit pension plans. The overall level of Viad’s contributions to its multi-employer plans may significantly vary from year to year based on the demand for union-represented labor to support the Company’s operations. Viad does not have any minimum contribution requirements for future periods pursuant to its collective-bargaining agreements for individually significant multi-employer plans. Viad’s participation in multi-employer pension plans for 2015 is outlined in the following table. Unless otherwise noted, the most recent Pension Protection Act zone status available in 2015 and 2014 relates to the plan’s year end as of December 31, 2014 and 2013, respectively, and is based on information received from the plan. Among other factors, plans in the red zone are generally less than 65 percent funded, plans in the yellow zone are less than 80 percent funded, and plans in the green zone are at least 80 percent funded. The “FIP/RP Status Pending/Implemented” column indicates plans for which a financial improvement plan or a rehabilitation plan is either pending or has been implemented.

Other Employee Benefits. The Company matches U.S. employee contributions to the 401(k) plan with shares of Viad common stock up to 100 percent of the first 3 percent of a participant’s salary plus 50 percent of the next 2 percent. The expense associated with the Company match was $3.7 million, $3.3 million, and $1.3 million for 2015, 2014, and 2013, respectively. Historically, Viad has funded its matching contributions to employees’ 401(k) accounts through the Company’s leveraged ESOP feature of the Company’s 401(k) defined contribution plan. ESOP shares are treated as outstanding for income per share calculations. During 2014, the Company depleted these shares and matching contributions are now funded from shares of Viad common stock held in treasury. Refer to Note 14 – Employee Stock Ownership Feature of 401(k) Plan for further information.
