In the last ten years Staple Inn has played host to two major discussions on performance measurement. In November 1976, Holbrook's definitive paper to the Institute set out in some detail the theoretical basis of performance measurement while in January 1980 Hager's paper to the Student's Society gave a detailed view of performance measurement in practice.

Between them the two papers provide a fairly comprehensive description of what was, even in 1980, a relatively novel science for many U.K. pension funds. At the time of writing the majority of large- and medium-sized directly invested pension funds have their investment performance measured. Yet even after fifteen years of performance measurement in the U.K. some of the fundamentals of performance measurement are questioned and even disputed by a sizeable proportion of actuaries—for example in his March 1985 paper to the Faculty of Actuaries Marshall states, “This must call in question the validity of its (the Time Weighted Rate of Return) use for comparative purposes”.
