In the United States the theoretical and practical aspects of the measurement of investment performance have been well researched, and the investment managers and pension fund trustees are accustomed to having a battery of statistics available on the performance of a pension fund.

By contrast, in the United Kingdom, attention has only really been given to this subject in this decade. It has taken time for both investment managers and trustees to appreciate the need to measure performance and to move away from a solely qualitative assessment of the ability of investment managers to one involving a quantitative element.

There are just a few papers by U.K. authors on the investment performance of pension funds and the Institute has discussed the subject only once. This was in November 1976 when J. P. Holbrook presented a comprehensive paper covering both theoretical and practical aspects of performance measurement.
