Required supplementary information for pension plans is typically presented for how many years?

Required supplementary information (RSI) for pension plans is typically presented for a period of ten years. This ten-year timeframe allows stakeholders, including members of the pension plan, investors, and regulatory bodies, to analyze trends and assess the financial health and stability of the pension plan over a substantial duration. Presenting data over multiple years enhances the ability to track important metrics such as funding status, actuarial assumptions, and changes in net pension liability or asset values. This trend analysis is vital for ensuring that adequate resources are maintained to meet future obligations and for providing transparency in financial reporting, thereby enabling informed decision-making. The length of ten years is consistent with the guidance provided by the Governmental Accounting Standards Board (GASB) for pension reporting, which reinforces the importance of long-term perspective in financial assessments.
