The assets are primarily valued based on Level 1 and Level 2 inputs under the fair value hierarchy in FASB ASC Topic No. 820, with the majority of the invested assets considered to be of low-to-medium investment risk. The Company projects a future long-term rate of return on these plan assets of 2.7%, which it believes is reasonable based on the composition of the assets and both current and projected market conditions. For the year-ended December 31, 2016, the Company contributed $2.4 million to these plans, and benefits paid to participants were $1.6 million. (2) The Funded status - shortfall represents the amount of the projected benefit obligation that the Company has not funded with a third-party trustee. This amount is a liability of the Company and is recorded in Other liabilities on the Company’s Consolidated Balance Sheets.

The impact of this amortization on pension expense in 2017 is projected to result in approximately $0.3 million of additional expense. The amortization of deferred actuarial losses from AOCL/I to pension expense in each of the three years ended December 31, 2016 was immaterial.
