PENSION, POST-RETIREMENT AND POST-EMPLOYMENT PLANS

PENSION, POST-RETIREMENT AND POST-EMPLOYMENT PLANS

For 2020, 2019 and 2018, the net periodic (benefit)/cost for all plans totaled $(1.8) million, $1.0 million and $0.1 million, respectively.

Domestic Defined Benefit Pension Plan

The domestic non-contributory defined benefit pension plan is closed to new participants. Pursuant to this plan, retirement benefits are provided based upon years of service and compensation levels. An investment committee, appointed by the Board, manages the plan and its assets in accordance with the plan’s investment policies. The Company’s investment policies incorporate an asset allocation strategy that emphasizes the long-term growth of capital and acceptable asset volatility as long as it is consistent with the volatility of the relevant market indexes. The investment policies attempt to achieve a mix of approximately 90% of plan investments for liability-matching, 8% for long-term growth, and 2% for near-term benefit payments. These allocation targets exclude the market value of equity derivatives. The Company believes this strategy is consistent with the long-term nature of plan liabilities and ultimate cash needs of the plans. Plan assets consist primarily of listed stocks, equity security funds, short-term Treasury bond mutual funds, derivatives and limited partnership interests. The weighted average asset allocation of this pension plan was 55% limited partnership interests and managed funds, 34% fixed income holdings, 9% equity securities, and 2% cash at December 31, 2020.

Actual pension expense and future contributions required to fund this pension plan will depend on future investment performance, changes in future discount rates, the level of Company contributions and various other factors related to the populations participating in this pension plan. The Company evaluates the plan's actuarial assumptions on an annual basis, including the expected long-term rate of return on assets and discount rate, and adjusts the assumptions, as necessary, to ensure proper funding levels are maintained so that the plan can meet obligations as they become due.

At December 31, 2020 and 2019, the projected benefit obligation for this pension plan totaled $230 million and $220 million, respectively.

Supplemental Executive Retirement Plans

The Company sponsors SERPs that entitle certain employees to the difference between the benefits actually paid to them and the benefits they would have received under the pension plan described above were it not for certain restrictions imposed by the Internal Revenue Service Code. Covered compensation under the SERPs includes an employee’s annual salary and bonus. At December 31, 2020 and 2019, the projected benefit obligation for the SERPs totaled $8.1 million and $8.0 million, respectively.

Foreign Pension Plans

The Company's international benefit plans are included in the tables presented below. These plans are not significant, individually or in the aggregate, to the Company's consolidated financial position, results of operations or cash flows. At December 31, 2020 and 2019, the projected benefit obligation for these foreign pension plans totaled $26.1 million and $26.6 million, respectively.

Certain other foreign subsidiaries maintain benefit plans that are consistent with statutory practices, but do not meet the criteria for pension or post-retirement accounting and have therefore been excluded from the tables presented below. These benefit plans had obligation balances of $1.4 million and $1.1 million at December 31, 2020 and 2019, respectively, and were recorded in the Consolidated Balance Sheets as "Pension and post-retirement benefits."

Domestic Defined Benefit Post-Retirement Medical and Dental Plan

The Company sponsors defined benefit post-retirement medical and dental plans that covers all of its MacDermid domestic full-time employees, hired prior to April 1, 1997, who retire after age 55, with at least ten to twenty years of service (depending upon the date of hire). Eligible employees receive a subsidy from the Company towards the purchase of their retiree medical benefits based on the date of retirement. The annual increase in the Company’s costs for post-retirement medical benefits is subject to a limit of 5%. Retirees are required to contribute to the plan costs in excess of their respective Company limits in addition to their other required contributions. The projected benefit obligation for the post-retirement plan at December 31, 2020 is comprised of 38% retirees, 33% fully eligible active participants and 29% other participants. The actuarial

determination of the Company's accumulated benefit obligation associated with the plan for post-retirement medical benefits assumes annual cost increases of 2% and 4%, based on the date of retirement.

The components of net periodic (benefit)/cost of the Domestic and Foreign Pension Plans and Post-Retirement Medical Benefits were as follows:

The weighted average key assumptions used to determine the net periodic (benefit)/cost of the Domestic and Foreign Pension Plans are as follows:

	Year Ended December 31,
	2020		2019		2018
	Domestic	Foreign	Domestic	Foreign	Domestic	Foreign
Pension and SERP Benefits
Discount rate	3.3%	1.0%	4.4%	1.5%	3.7%	1.4%
Rate of compensation increase	3.5%	3.1%	3.5%	3.4%	3.5%	3.4%
Interest crediting rate	5.3%	2.6%	5.2%	2.6%	5.2%	2.6%
Long-term rate of return on assets	5.1%	1.7%	5.4%	1.4%	5.4%	1.8%
Post-retirement Medical Benefits
Discount rate	3.2%	7.3%	4.3%	9.2%	3.7%	9.9%

The expected long-term rate of return on assets assumption is developed with reference to historical returns, forward-looking return expectations, the Domestic and Foreign Pension Plans' investment allocations and peer comparisons.
