Defined Contribution Plan
The Company has a 401(k) defined contribution retirement plan (the 401(k) Plan) covering all eligible employees. Participants may voluntarily contribute on a pre-tax basis an amount not to exceed a maximum contribution amount pursuant to Section 401(k) of the Internal Revenue Code. The Company is not required to contribute, nor has it contributed, to the 401(k) Plan for any of the periods presented.
Pension and Other Defined Benefit Retirement Obligations
In connection with the July 31, 2020 acquisition of the Wi-Fi and Broadband assets business (Note 3), the Company assumed an obligation of $7.9 million associated with certain defined benefit retirement plans, including a pension plan. The benefit is based on a formula applied to eligible employee earnings. Net periodic benefit costs were $0.2 million for the year ended December 31, 2020 and were recorded to research and development expenses in the consolidated statement of operations.
Benefit Obligation and Plan Assets for Pension Benefit Plans
The vested benefit obligation for a defined-benefit pension or other retirement plan is the actuarial present value of the vested benefits to which the employee is currently entitled based on the employee's expected date of separation or retirement.
Changes in actuarial gains and losses in the projected benefit obligation are primarily driven by discount rate movement. The Company uses the corridor approach to amortize actuarial gains and losses. Under this approach, net actuarial gains or losses in excess of 10% of the larger of the projected benefit obligation or the fair value of plan assets are amortized on a straight-line basis.
As of December 31, 2020, all plans had accumulated benefit obligations and projected benefit obligations in excess of plan assets. As of December 31, 2020, the accumulated benefit obligations were $11.1 million for the pension plans.
Assumptions for Pension Benefit Plans
The Company establishes the discount rate for each pension plan by analyzing current market long-term bond rates and matching the bond maturity with the average duration of the pension liabilities. The Company establishes the long-term expected rate of return by developing a forward-looking, long-term return assumption for each pension fund asset class, taking into account factors such as the expected real return for the specific asset class and inflation. A single, long-term rate of return is then calculated as the weighted average of the target asset allocation percentages and the long-term return assumption for each asset class.
Pension Plan Assets
The plan assets are currently all in liquid cash and cash equivalents and an investment strategy is being developed to ensure that sufficient assets are available to pay pension benefits as they come due.
