Retirement Benefits [Abstract] |
PENSION BENEFITS | NOTE 12. PENSION BENEFITS Our Company and our subsidiaries have defined benefit and defined contribution pension plans that cover substantially all of our employees. Defined Benefit Pension Plan We have a defined benefit pension plan in accordance with the Labor Standards Law of the Republic of China (R.O.C.) for our employees located in Taiwan, covering substantially all full-time employees for services provided prior to July 1, 2005, and employees who have elected to remain in the defined benefit pension plan subsequent to the enactment of the Labor Pension Act on July 1, 2005. Under the defined benefit pension plan, employees are entitled to a lump sum retirement benefit upon retirement equivalent to the aggregate of 2 months’ pensionable salary for each of the first 15 years of service and 1 month’s pensionable salary for each year of service thereafter subject to a maximum of 45 months’ pensionable salary. The pensionable salary is the monthly average salary or wage of the final six months prior to approved retirement. We use December 31 as the measurement date for our defined benefit pension plan. As of December 31, 2022 and 2021, the accumulated benefit obligation amounted to $247 thousand and $294 thousand, respectively, and the funded status of prepaid pension assets amounted to $142 thousand and $83 thousand, respectively. The fair value of plan assets amounted to $463 thousand and $473 thousand as of December 31, 2022 and 2021, respectively. The accumulated other comprehensive loss amounted to ($4) thousand and ($80) thousand as of December 31, 2022 and 2021, respectively. The net periodic benefit cost for 2022, 2021 and 2020 amounted to $1 thousand, $3 thousand and $1 thousand, respectively. The following table sets forth the plan’s benefit obligations, fair value of plan assets, and funded status at December 31, 2022 and 2021:

|  | December 31 |
|  | 2022 |  |  | 2021 |
Discount rate |  |  | 1.750 | % |  |  | 0.750 | %

Weighted average assumptions used to determine net periodic benefit cost for end of fiscal year were as follows:
|  | 2022 |  |  | 2021 |
Discount rate |  |  | 0.750 | % |  |  | 0.750 | %

Management determines the discount rate and rate of return on plan assets based on the yields of fifteen year ROC central government bonds which is in line with the respective employees remaining service period and the historical rate of return on the above mentioned Fund mandated by the ROC Labor Standard Law. We have contributed an amount equal to 2% of the salaries and wages paid to all qualified employees located in Taiwan to a pension fund (the “Fund”). The Fund is administered by a pension fund monitoring committee (the “Committee”) and deposited in the Committee’s name in the Bank of Taiwan. Our Company makes pension payments from our account in the Fund unless the Fund is insufficient, in which case we make payments from internal funds as payments become due. We seek to maintain a normal, highly liquid working capital balance to ensure payments are made timely. We expect to make a contribution of $0 thousand to the Fund in 2023. We expect to make future benefit payments of $5 thousand to employees from 2023 to 2027 and $66 thousand from 2028 to 2032. Defined Contribution Pension Plans We have provided defined contribution plans for employees located in Taiwan and Hong Kong. Contributions to the plans are expensed as incurred. Taiwan Pursuant to the new “Labor Pension Act” enacted on July 1, 2005, our Company has a defined contribution pension plan for our employees located in Taiwan. For eligible employees who elect to participate in the defined contribution pension plan, we contribute no less than 6% of an employee’s monthly salary and wage and up to the maximum amount of NT$9 thousand (approximately $293), to each of the eligible employees’ individual pension accounts at the Bureau of Labor Insurance each month. Pension payments to employees are made either by monthly installments or in a lump sum from the accumulated contributions and earnings in employees’ individual accounts. Hong Kong According to the relevant Hong Kong regulations, we provide a contribution plan for the eligible employees in Hong Kong. We must contribute at least 5% of the employees’ total salaries. For this purpose, the monthly relevant contribution to their individual contribution accounts is subject to a cap of HK$1.5 thousand (approximately $192). After the termination of employment, the benefits still belong to the employees in any circumstances. The total amount of defined contribution pension expenses pursuant to our defined contribution plans for the years ended December 31, 2022, 2021 and 2020 were $167 thousand, $193 thousand, and $187 thousand, respectively, which are included in operating expenses.
