Key Terms

pension administration, pension plan trustees

2 terms

pension administration financial

"First Actuarial provides pension administration, employee benefits, consultancy"

Pension administration is the day‑to‑day management of a retirement plan — keeping records, collecting contributions, calculating and paying benefits, and making sure rules and taxes are followed. Like a combined payroll, accounting and customer‑service team for retirees, it matters to investors because poor administration can increase costs, create legal or tax liabilities, damage employee trust, and affect a company’s reported pension obligations and cash flow.

pension plan trustees financial

"services to employers and pension plan trustees throughout the UK."

Pension plan trustees are the people or board legally responsible for running a retirement plan and protecting the money set aside for workers’ future paychecks. Think of them as stewards of a shared piggy bank: they decide how contributions are invested, ensure promised benefits can be paid, and set rules for payouts. Their choices affect a plan’s financial health and can influence a company’s liabilities, funding needs, and thus investor outcomes.
