The 401(k) Retirement Plan is a defined contribution plan under which eligible employees may defer a portion of their pre-tax covered compensation on an annual basis, with employer matches of up to 5% of employee compensation. Employee and employer contributions under these features are 100% vested.

Contributions to the Defined Benefit Pension Plan ("Pension Plan") are actuarially determined and funded annually, if necessary. The Corporation recognizes the funded status of its Pension Plan on the consolidated balance sheets and recognizes the changes in that funded status through other comprehensive income. The Pension Plan has been curtailed, with no additional benefits accruing to participants.

The Pension Plan was curtailed effective January 1, 2008. Pension plan service cost for all years presented was related to administrative costs associated with the plan and not due to the accrual of additional participant benefits. Beginning January 1, 2017 the administrative costs were netted with the expected return on assets.

The total amount of unrecognized net loss that will be amortized as a component of net periodic pension cost in 2019 is expected to be $2.3 million.

The following rates were used to calculate net periodic pension cost and the present value of benefit obligations as of December 31:

The discount rates used were determined using the Citigroup Average Life discount rate table, as adjusted based on the Pension Plan's expected benefit payments and rounded to the nearest 0.25%.
The 5.00% long-term rate of return on plan assets used to calculate the net periodic pension cost was based on historical returns, adjusted for expectations of long-term asset returns based on the December 31, 2018 weighted average asset allocations. The expected long-term return is considered to be appropriate based on the asset mix and the historical returns realized.

Investment allocation decisions are made by a retirement plan committee. The goal of the investment allocation strategy is to match certain benefit obligations with maturities of fixed income securities. Pension Plan assets are invested with a balanced objective, with target asset allocations of approximately 50% in equities, 40% in fixed income securities and cash and 10% in alternative investments. Alternative investments may include managed futures, commodities, real estate investment trusts, master limited partnerships, and long-short strategies with traditional stocks and bonds. All alternative investments are in the form of mutual funds, not individual contracts, to enable daily liquidity.
The fair values for all assets held by the Pension Plan, excluding equity common trust funds, are based on quoted prices for identical instruments and would be categorized as Level 1 assets under FASB ASC Topic 810. Equity common trust funds would be categorized as Level 2 assets under FASB ASC Topic 810.

Postretirement Benefits

The Corporation provides medical benefits and life insurance benefits under a postretirement benefits plan ("Postretirement Plan") to certain retired full-time employees who were employees of the Corporation prior to January 1, 1998. Prior to February 1, 2014, certain full-time employees became eligible for these discretionary benefits if they reached retirement age while working for the Corporation. The Corporation recognizes the funded status of the postretirement plan on the consolidated balance sheets and recognizes the changes in that funded status through other comprehensive income.
