Pursuant to the Employee Retirement Benefit Security Act of Korea, eligible employees and executive officers with one or more years of service are entitled to severance benefits upon the termination of their employment based on their length of service and rate of pay. As of September 30, 2025, 97% of all employees of the Company were eligible for severance benefits. Changes in accrued severance benefits are as follows (in thousands):

The severance benefits funded through the Company’s National Pension Fund have been and will be used exclusively for payment of severance benefits to eligible employees. These amounts have been deducted from the accrued severance benefit balance. Beginning in July 2018, the Company contributes to certain severance insurance deposit accounts a certain percentage of severance benefits that are accrued for eligible employees for their services from January 1, 2018 pursuant to Employee Retirement Benefit Security Act of Korea. These accounts consist of time deposits and other guaranteed principal and interest, and are maintained at insurance companies, banks or security companies for the benefit of employees. The Company deducts the contributions made to these severance insurance deposit accounts from its accrued severance benefits. The Company is liable to pay the following future benefits to its non-executive employees upon their normal retirement age (in thousands):
|  | Severance benefit |
2026 |  | $ | 94 |
2027 |  | $ | 539 |
2028 |  | $ | 106 |
2029 |  | $ | 2,216 |
2030 |  | $ | 2,643 |
2031 – 2036 |  | $ | 17,339 |
The above amounts were determined based on the non-executive employees’ current salary rates and the number of service years that will be accumulated upon their retirement dates. These amounts do not include amounts that might be paid to non-executive employees that will cease working with the Company before their normal retirement ages. Korea’s mandatory retirement age is 60 years of age or older under the Employment Promotion for the Aged Act. The Company sets the retirement age of employees at 60.
