Employee benefits

Defined benefit plans

Pursuant to the ROC Labor Standards Law, the Company has established a defined benefit pension plan covering full-time employees in the ROC that provides retirement benefits to retiring employees based on years of service and the average salary for the six-month period before the employee’s retirement.

Reconciliations of defined benefit obligation at present value and plan asset at fair value are as follows:

	January 1, 2017			December 31, 2017			December 31, 2018
	(in thousands)

Plan assets

The Company contributes an amount equal to 2% of wages and salaries paid every month to the Fund (required by law). The Fund is administered by a pension fund monitoring committee (the “Committee”) and is deposited in the Committee’s name in the Bank of Taiwan. Under the ROC Labor Standards Law, the minimum return on the plan assets should not be lower than the average interest rate on two-year time deposits published by the local banks. As of December 31, 2018, the Funds deposited in the Committee’s name in the Bank of Taiwan amounted to $3,565 thousand.

	January 1, 2017						December 31, 2017						December 31, 2018
	+0.5%			-0.5%			+ 0.5%			- 0.5%			+ 0.5%			-0.5%

Defined contribution plans

Beginning July 1, 2005, pursuant to the newly effective ROC Labor Pension Act, the Company is required to make a monthly contribution for full-time employees in the ROC that elected to participate in the Defined Contribution Plan at a rate no less than 6% of the employee’s monthly wages to the employees’ individual pension fund accounts at the ROC Bureau of Labor Insurance. Expenses recognized in 2017 and 2018, based on the contribution called for were $3,367 thousand and $3,527 thousand, respectively.

The Company established a defined contribution plan in the United States that qualifies under Section 401(k) of the Internal Revenue Code. This plan covers substantially all employees who meet the service requirement. The Company’s contribution to the plan may be made at the discretion of the board of directors. As now, no contributions have been made by the Company to the plan.

All PRC employees participate in employee social security plans, including pension and other welfare benefits, which are organized and administered by governmental authorities. The Company has no other substantial commitments to employees. The premiums and welfare benefit contributions that should be borne by the Company are calculated in accordance with relevant PRC regulations, and are paid to the labor and social welfare authorities. Expenses recognized based on this plan were $1,523 thousand and $1,655 thousand for the years ended December 31, 2017 and 2018, respectively.

Other foreign subsidiaries recognized pension expenses of $178 thousand and $253 thousand for the years ended December 31, 2017 and 2018, respectively, for the defined contribution plans based on their respective local government regulations.
