b'LOW-DEFAULT-RISKOBLIGATION MEASURE (LDROM)Beginning with the June 30, 2023 valuation, the Plan is required to report on the LDROM under Actuarial Standard of Practice No. 4. The LDROM is calculated using a discount rate based entirely on high quality bond yields instead of the expected return on the Plans diversified investment portfolio. As of June 30, 2024, the LDROM for the Plan is $41.9 billion. The difference between the Plans Actuarial Accrued Liabil-ity for pension benefits of $27.6 billion and the LDROM of $41.9 billion can be thought of as representing the expected savings from investing in the Plans diversified portfolio compared to investing only in low-default-risk securities.
