Employee Benefit Plans

13. EMPLOYEE BENEFIT PLANS

Defined Benefit Pension Plans.

The Company maintains both qualified and non-qualified defined benefit pension plans for its U.S. employees employed prior to April 1, 2010. Generally, the Company computes the benefits based on average earnings over a period prescribed by the plans and credited length of service. The Company’s non-qualified defined benefit pension plan provided compensating pension benefits for participants whose benefits have been curtailed under the qualified plan due to Internal Revenue Code limitations. Effective January 1, 2018, participants of the Company’s non-qualified defined benefit pension plan may no longer accrue additional service benefits.

Although not required to make contributions under IRS regulations, the following table summarizes the Company’s contributions to the defined benefit pension plans for the periods indicated:

Plan assets consist of shares in investment trusts with 72%, 27%, 1% and 0% of the underlying assets consisting of equity securities, fixed maturities, limited partnerships and multi-strategy equity funds and cash, respectively. The Company manages the qualified plan investments for U.S. employees. The assets in the plan consist of debt and equity mutual funds. Due to the long term nature of the plan, the target asset allocation has historically been 70% equities and 30% bonds.

In addition, $4,596 thousand and $20,351 thousand of investments which were recorded as part of the qualified plan assets at December 31, 2020 and 2019, respectively, are not included within the fair value hierarchy tables as the assets are valued using the NAV practical expedient guidance within ASU 2015-07.

The Company contributed $0 thousand to the qualified pension benefit plan for the years ended December 31, 2020 and 2019.

Defined Contribution Plans.

The Company also maintains both qualified and non-qualified defined contribution plans (“Savings Plan” and “Non-Qualified Savings Plan”, respectively) covering U.S. employees. Under the plans, the Company contributes up to a maximum 3% of the participants’ compensation based on the contribution percentage of the employee. The Non-Qualified Savings Plan provides compensating savings plan benefits for participants whose benefits have been curtailed under the Savings Plan due to Internal Revenue Code limitations. In addition, effective for new hires (and rehires) on or after April 1, 2010, the Company will contribute between 3% and 8% of an employee’s earnings for each payroll period based on the employee’s age. These contributions will be 100% vested after three years.

The following table presents the Company’s incurred expenses related to these plans for the periods indicated:

	Years Ended December 31,
(Dollars in thousands)	2020			2019			2018
Incurred expenses	$	14,386		$	10,794		$	9,301

In addition, the Company maintains several defined contribution pension plans covering non-U.S. employees. Each non-U.S. office (Brazil, Canada, London, Belgium, Singapore, Ireland, Zurich and Bermuda) maintains a separate plan for the non-U.S. employees working in that location. The Company contributes various amounts based on salary, age and/or years of service. In the current year, the contributions as a percentage of salary for the branch offices ranged from 5.1% to 64.8%. The contributions are generally used to purchase pension benefits from local insurance providers. The following table presents the Company’s incurred expenses related to these plans for the periods indicated:

	Years Ended December 31,
(Dollars in thousands)	2020			2019			2018
Incurred expenses	$	3,039		$	2,216		$	2,057

Post-Retirement Plan.

The Company sponsors a Retiree Health Plan for employees employed prior to April 1, 2010. This plan provides healthcare benefits for eligible retired employees (and their eligible dependents), who have elected coverage. The Company anticipates that most covered employees will become eligible for these benefits if they retire while working for the Company. The cost of these benefits is shared with the retiree. The Company accrues the post-retirement benefit expense during the period of the employee’s service.

A medical cost trend rate of 6.75% in 2020 was assumed to decrease gradually to 4.75% in 2030 and then remain at that level.
