$134,919 million at September 30, 2023. This amount of $120,858 million (as compared to investments under
management of $117,031 million, as reported in section VIII Investment Activities) reflects the fact that
PBGC experiences a recurring inflow of trusteed plan assets that have not yet been incorporated into the
PBGC investment program. For total investments (i.e., not the investment program), cash and fixed-income
securities ($105,385 million) represent 87 percent of the total investments, while equity securities ($13,389
million) represent 11 percent of total investments. Private market assets, real estate, and other investments
($2,084 million), represent 2 percent of the total investments.
SINGLE-EMPLOYER AND MULTIEMPLOYER PROGRAM EXPOSURE
PBGC’s estimate of the total underfunding in single-employer plans was $25,657 million for those sponsored
by companies that have credit ratings below investment grade and that PBGC classified as reasonably
possible of termination, as of September 30, 2023. This is a decrease of $26,375 million from the reasonably
possible exposure of $52,032 million in FY 2022. This decrease is primarily due to the increase in the interest
factors used for valuing liabilities as of the measurement date. These estimates are determined using a
measurement date of December 31 of the previous year (see Note 9). For FY 2023, this exposure is
concentrated in the following sectors: manufacturing, transportation/communications/utilities, and services.
PBGC estimates that as of September 30, 2023, it is reasonably possible that multiemployer plans may require
future financial assistance in the amount of $410 million (see Note 9). This is a decrease of $1,808 million
from the reasonably possible exposure of $2,218 million in FY 2022. The primary reason for the decrease in
exposure was a net decrease in the number of plans classified as reasonably possible to seven plans at
September 30, 2023, down from 12 plans classified as reasonably possible at September 30, 2022. The plans
removed no longer meet the reasonably possible criteria as the plans experienced improved financial
conditions due to better than expected investment returns, higher discount rates in valuing liabilities, and
higher plan contributions. One of the plans was removed since it is eligible for SFA. Additionally, the
reasonably possible aggregate reserve for small plans decreased by $390 million due to improved financial
conditions of the plans, higher discount rates in valuing liabilities and a change in the small plan bulk reserve
estimation methodology. The number of small plans projected to become insolvent within 20 years decreased
from 55 to 41.
There is significant volatility in plan underfunding and sponsor credit quality over time, which makes long-
term estimation of PBGC’s expected claims difficult. This volatility, along with the concentration of claims in
a relatively small number of terminated plans, has characterized PBGC’s experience to date and will likely
continue. Among the factors that will influence PBGC’s claims going forward are economic conditions
affecting interest rates, financial markets, and the rate of business failures.
PBGC’s sources of information on plan underfunding are the most recent Section 4010 and PBGC premium
filings and other submissions to the Corporation. PBGC publishes Table S-49, “Various Measures of
Underfunding in PBGC-Insured Plans,” in its Pension Insurance Data Tables where the limitations of the
estimates are appropriately described.
Under the Single-Employer Program, PBGC is liable for the payment of guaranteed benefits with respect to
underfunded terminated plans. An underfunded plan may terminate only if PBGC or a bankruptcy court
finds that one of the four conditions for a distress termination, as defined in ERISA, is met or if PBGC
initiates terminating a plan under one of five specified statutory tests. The net liability assumed by PBGC is
generally equal to the present value of the future benefits payable by PBGC less amounts provided by the
plan’s assets and amounts recoverable by PBGC from the plan sponsor and members of the plan sponsor’s
controlled group, as defined by ERISA.
Under the Multiemployer Program, if a plan becomes insolvent, it receives traditional financial assistance
from PBGC to allow the plan to continue to pay participants their guaranteed benefits. PBGC recognizes
assistance as a loss to the extent that the plan is not expected to be able to repay these amounts from future
