Combined Actuarial
performance Services (commonly “CAPS”) describes a widely used performance measurement and
benchmarking service for occupational pension schemes. In practice, trustees and their advisers use CAPS “peer group” data to compare a scheme’s investment returns and risk profiles against those of other institutional
funds and managers, and to assess whether performance is in line with market norms.
This is a market expression rather than a term defined by legislation or case law. It typically appears in investment reports, manager review papers, and trustee meeting materials to provide time‑series performance, quartile rankings and strategy-level comparisons. CAPS data may inform trustee decisions on manager appointment, retention or termination, and can help evidence prudent monitoring in line with regulatory expectations on governance and investment oversight.
Use and understanding are broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland, although schemes also references other benchmarking universes or successor services. In disputes or negotiations concerning underperformance, CAPS-style benchmarks are often cited to contextualise outcomes relative to a relevant peer group.
Historically one of the largest pension performance datasets in the UK market, “CAPS” is sometimes used generically to mean recognised peer‑group pension fund benchmarking.
