An Empirical Examination Of Pension Rate Estimates: A Benchmark Approach

Abstract

In this paper, we analyze pension rate choices for a sample of 495 firms over the thirteen-year period from 1994-2006. In recent years, articles have appeared in business publications alleging abuse of the discretion afforded to management in setting pension rates, particularly the pension discount rate and expected rate of return on plan assets. We find that pension discount rate estimates and expected rate of return estimates generally comply with the authoritative requirements, although there appears to be a smoothing effect in setting pension discount rates as well as a lag in fully reflecting economic conditions. We find evidence consistent with discount rate choice being influenced by deteriorating economic conditions, and possibly passage of the Sarbanes-Oxley Act. We also find that, in general, firms’ expected rate of return assumptions tend to reflect their long-run internal rates of return on pension assets, although the recessionary influences in the early 2000s were not fully reflected in the expected rates of return toward the end of our test period. There is also a sizeable minority of firms (approximately 27%) for which their expected rates of return on plan assets consistently overstate their actual, long-run returns.
