17.2 Policies on defined benefit plan This policy is applied to all benefits received for services provided by the Company’s employees. This is divided as follows: a)Short-term benefits for active employees are represented by salaries, social welfare benefits, paid time off, sickness and other types of leave, profit sharing and incentives and non-monetary benefits; e.g., healthcare service, housing, subsidized or free goods or services. These will be paid in a term which does not exceed twelve months. The Company maintains incentive programs for its employees, which are calculated based on the net result at the close of each period by applying a factor obtained from an evaluation based on their personal performance, the Company’s performance and other short-term and long-term indicators. b)Staff severance indemnities are agreed and payable based on the final salary, calculated in accordance with each year of service to the Company, with certain maximum limits in respect of either the number of years or in monetary terms. In general, this benefit is payable when the employee or worker ceases to provide his/her services to the Company and there are a number of different circumstances through which a person can be eligible for it, as indicated in the respective agreements; e.g. retirement, dismissal, voluntary retirement, incapacity or disability, death, etc. See Note 17.3. c)Obligations after employee retirement, described in Note 17.4. d)Retention bonuses for a group of Company executives, described in Note 17.6. 17.3 Other long-term benefits The actuarial assessment method has been used to calculate the Company’s obligations with respect to staff severance indemnities, which relate to defined benefit plans consisting of days of remuneration per year served at the time of retirement under conditions agreed in the respective agreements established between the Company and its employees. Under this benefit plan, the Company retains the obligation to pay staff severance indemnities related to retirement, without establishing a separate fund with specific assets, which is referred to as not funded. Benefit payment conditions The staff severance indemnity benefit relates to remuneration days for years worked for the Company without a limit being imposed in regard of amount of salary or years of service. It applies when employees cease to work for the Company because they are made redundant or in the event of their death. This benefit is applicable up to a maximum age of 65 for men and 60 for women, which are the usual retirement ages according to the Chilean pensions system as established in Decree Law 3,500 of 1980. Methodology The determination of the defined benefit obligation is made under the requirements of IAS 19 “Employee benefits”. 17.4 Post-employment benefit obligations Our subsidiary SQM NA, together with its employees established a pension plan until 2002 called the “SQM North America Retirement Income Plan”. This obligation is calculated measuring the expected future forecast staff severance indemnity obligation using a net salary gradual rate of restatements for inflation, mortality and turnover assumptions, discounting the resulting amounts at present value using the interest rate defined by the authorities. For workers under contract, since 2003, SQM NA offers benefits related to pension plans based on the 401-K system to its employees, which does not generate obligations for the Company. A settlement was reflected in the last quarter of 2022 for the purchase of annuities by the pension plan for all inactive participants.
