Actuarial Aspects of the National Social Insurance Trust Fund Operations in Nigeria

This study examines the actuarial aspects of the National Social Insurance Trust Fund operations in Nigeria, focusing on benefit adequacy, contribution sustainability, and long-term financial viability. NSITF administers workplace injury compensation benefits under the Employee Compensation Act, funded through employer contributions of one percent of employee annual emoluments. The actuarial soundness of a social insurance fund of this nature depends on the adequacy of contribution rates relative to benefit obligations, investment performance, and administrative efficiency. This study uses secondary data from NSITF annual reports, audit reports, and benefit payment schedules for 2018 to 2023, supplemented by interviews with 30 NSITF actuarial and finance officers. An actuarial projection model is constructed to assess the fund's long-term contribution adequacy under three scenarios of benefit utilization, investment return, and employer compliance. Claims data are analyzed by injury type, industry sector, and geopolitical zone. Findings reveal that the one percent contribution rate produces a surplus under conservative assumptions but is vulnerable to deficit if large-scale industrial disasters increase claims significantly. Several northern states show lower registered employer compliance, reducing contribution inflows. The study concludes that NSITF's current financial position is adequate but sensitive to compliance and investment return risks. It recommends triennial actuarial review of the fund, mandatory employer registration compliance enforcement, and diversification of investment allocations to improve return resilience.
