In
order to project the long-term target investment return
for the total portfolio, estimates are prepared for
the total return of each major asset class over the
subsequent 10-year period, or longer. Those estimates
are based on a combination of factors including the
following: observable current market interest rates,
consensus earnings expectations, historical long-term
performance and value-added, and the use of conventional
long-term risk premiums. To determine the aggregate
return for the pension trust, the projected return of
each individual asset class is then weighted according
to the allocation to that investment area in the trust’s
long-term asset allocation policy. The projected long-term
results are then also compared to the investment return
earned over the previous 10 years.
