​ a) Post-employment defined benefit pension plan The Company’s Canadian and US subsidiaries sponsor defined benefit plans (Canadian Plan and American Plan), collectively referred to as the North American Plans, that cover substantially all their employees and provide supplemental benefits to employees during retirement. The assumptions adopted for pension plans can have a significant effect on the amounts disclosed and recorded for these plans. The Company and its subsidiaries in Brazil sponsor a defined benefit pension plan (Brazilian plans), managed by Gerdau - Sociedade de Previdência Privada (GPrev), a closed supplementary pension plan, which were settled in 2010 and include only participants who decided not to transfer the reserve to a new defined contribution plan and, therefore, opted to maintain the benefit settled in the defined benefit plan, which has been adjusted by the INPC (National Consumer Price Index). The potential effects of changes to the North American Plans on the Consolidated Statement of Income are presented below: ​

​ Actuarial remeasurements are recognized in the period in which they occur and are recorded directly in comprehensive income. The allocations for plan assets are presented below: ​
​ | ​ | ​ | ​ | ​
​ | ​ | 2023
​ |  | Brazilian Plans |  | American Plans
Fixed income |  | 99.7% | ​ | 83.6%
Variable income |  | — | ​ | 11.6%

Others |  | 0.5% | ​ | 10.7%
Total |  | 100.0% | ​ | 100.0%
​ The investment strategy for the Brazilian Plan is based on a long-term macroeconomic scenario. This scenario assumes a reduction in Brazil’s sovereign risk, moderate economic growth, stable levels of inflation, exchange rates and moderate interest rates. The Canadian and American subsidiaries have an Investment Committee that defines the investment policy for the defined benefit plans. The primary investment objective is to ensure the security of benefits that were accrued under the plans, providing an adequately funded asset pool which is separated and independent of the Company. To reach this objective, the fund must invest in a manner that adheres to safeguards and diversification to which a prudent investor of pension funds would normally adhere. These subsidiaries retain specialized consultants that advice and support Investment Committee decisions and recommendations. The asset mix policy considers the principles of diversification and long-term investment goals, as well as liquidity requirements. To do this, the target allocation ranges between 10% in shares, 85% in debt securities and 5% in alternative securities, and for Brazilian Plan it is close to 100% in fixed income. The tables below show a summary of the assumptions used to calculate the defined benefit plans in 2023 and 2022, respectively: ​
​ | ​ | ​ | ​ | ​
​ |  | 2023

​ b) Post-employment defined contribution pension plan The Company and its subsidiaries in Brazil, in the United States and in Canada maintain a defined contribution plan to which contributions are made by the sponsor in proportion to the contributions made by its participating employees.

​ The assumptions adopted for post-employment health benefits have a significant effect on the amounts disclosed and recorded for post-employment health benefits plans. The change of one-point percentage on discount rates would have the following effects: ​
