 31, 2024 valuation is based on Pri-2012 and MMP-2021, adjusted to reflect (1) an ultimate rate of mortality improvement consistent with
both historical experience and U.S. Social Security long-term projections, and (2) a shorter transition period to reach the ultimate rate, which is consistent with historical patterns. In establishing the expected return on assets assumption,
Intelsat reviews the asset allocations considering plan maturity and develop return assumptions based on different asset classes. The return assumptions are established after reviewing historical returns of broader market indexes, as well as
historical performance of the investments in the plan.
