RETIREMENT PLANS
The Company has a defined benefit plan that covers many of its employees, or the Benefit Plan. The benefits are based on years of service and the employee’s five-year final average salary. Contributions are intended to provide for benefits attributable to service both to-date and expected-to-be provided in the future. The Company funds the plan in accordance with the Employee Retirement Income Security Act of 1974 (ERISA) and the Pension Protection Act. We do not expect to contribute to the plan during 2017.
Plan assets consist of equity, debt and short-term money market investment funds. The plan’s current investment policy targets 65% equities, 25% debt and 10% money market funds. Equity and debt investment percentages are allowed to fluctuate plus or minus 20% to take advantage of market conditions. As an example, equities could fluctuate from 78% to 52% of plan assets. At March 31, 2017, the investment mix was approximately 55% equity, 38% debt, and 7% money market funds. At December 31, 2016, the investment mix was approximately 60% equity, 29% debt and 11% money market funds. Equity investments consist of a combination of individual equity securities plus value funds, growth funds, large cap funds and international stock funds. Debt investments consist of U.S. Treasury securities and investment grade corporate debt. The weighted-average discount rate used in determining the periodic pension cost is 4.3% in 2017 and 2016. The expected long-term rate of return on plan assets is 7.5% in 2017 and 2016. The long-term rate of return on plan assets is based on the historical returns within the plan and expectations for future returns.
The expected total pension and retirement expense for the Benefit Plan was as follows:

The Company has a Supplemental Executive Retirement Plan, or SERP, to restore to executives designated by the Compensation Committee of the Board of Directors the full benefits under the pension plan that would otherwise be restricted by certain limitations now imposed under the Internal Revenue Code. The SERP is currently unfunded. The pension and retirement expense for the SERP was as follows:
