Estimated retiree buyout cost as a percentage of
accounting liability increased by 60 bps from
102.3% to 102.9% in October
Competitive pricing buyout costs rise
from 100.2% to 100.3%
As the Pension Risk Transfer market continues to grow, it has
become increasingly important for plan sponsors to monitor the
annuity buyout market when considering a plan termination or
de-risking strategy. While we continue to monitor annuity
purchase rates from all insurers, we have now also expanded our
analysis to reflect the possible impact of competitive pricing to
our estimated buyout cost. Figure 1 illustrates retiree buyout
costs based on both an average of all insurer rates in our study
and on just the most competitive rates, which represents the
price savings that may be achieved when selecting between bids
from multiple insurers.
During October 2020, average accounting discount rates
increased by 12bps, while annuity purchase rates increased by
6 bps (average) and 12 bps (competitive). This caused the
average estimated retiree buyout cost as a percentage of
accounting liability (accumulated benefit obligation) to increase
from 102.3% to 102.9%, while the competitive pricing trend
increased from 100.2% to 100.3%.
When considering these results, please keep the following
information in mind:
- Annuity pricing composites are provided by the following
insurers: Prudential Insurance Company of America,
American United Life Insurance Company (OneAmerica),
American General Life Insurance Company (subsidiary of
AIG), Minnesota Life Insurance Company (Securian), Pacific
Life Insurance Company, Metropolitan Tower Life Insurance
Company (MetLife), Massachusetts Mutual Life Insurance
Company (MassMutual), and Banner Life Insurance
Company (Legal & General America).
- Baseline accounting obligations are estimated using a
representative retiree population, the FTSE Above Median
AA Curve, and insurance company data.
- Plan sponsors should note that specific characteristics in plan
design or participant population could make settling pension
obligations with an insurer more or less costly than estimated.
