Funded Status of Our Plans

The funded status of the plans we sponsor is determined by comparing the projected benefit obligation with the fair value of plan assets at the end of the year. The following table demonstrates how our plans' funded status is reflected on our Consolidated Balance Sheet.

(1)
Actuarial (gain) loss is primarily due to year-over-year changes in discount rates.
(2)
Assets and liabilities on our Consolidated Balance Sheet are different from the cumulative income or expense that we have recorded associated with the plans. The differences are actuarial (gain) loss and prior service (cost) credit that are deferred and amortized into periodic benefit costs in future periods. Unamortized amounts are recorded in "Accumulated Other Comprehensive Loss", which is a component of total equity on our Consolidated Balance Sheet. The Accumulated Other Comprehensive Loss section of Note 14: Shareholders' Interest details changes in these amounts by component.
(3)
For pension plans with a projected benefit obligation exceeding plan assets, the projected benefit obligation and fair value of plan assets were $2.0 billion and $1.5 billion at December 31, 2024, respectively, and $2.1 billion and $1.7 billion at December 31, 2023, respectively. For pension plans with an accumulated benefit obligation exceeding plan assets, the accumulated benefit obligation and fair value of plan assets were $2.0 billion and $1.5 billion at December 31, 2024, respectively, and $2.1 billion and $1.7 billion at December 31, 2023, respectively.
(4)
For the U.S. defined benefit plans, the discount rate assumption was 5.7% and 5.2% for 2024 and 2023, respectively. For the Canadian defined benefit plans, the discount rate assumption was 4.7% for both 2024 and 2023. For U.S. OPEB plans, the discount rate assumption was 5.5% and 5.1% for 2024 and 2023, respectively. For Canadian OPEB plans, the discount rate assumption was 4.5% and 4.6% for 2024 and 2023, respectively. For lump sum distributions (for U.S. qualified salaried and nonqualified plans only), the interest and mortality assumptions are the same as those mandated by the Pension Protection Act of 2006 for benefits commencing in the current year.
(5)
For the U.S. defined benefit plans, the rate of compensation increase assumption for both 2024 and 2023 was between 2.00% - 13.00% for salaried participants and was decreasing with participant age. For the Canadian defined benefit plans, the rate of compensation increase assumption was 1.00% - 2.75% and 2.00% - 2.75% for salaried and hourly participants, respectively, for both 2024 and 2023.
(6)
U.S. qualified salaried and nonqualified plans only.
(7)
For U.S. OPEB plans, the healthcare cost trend rate assumption for the next year for Pre-Medicare was 7.00% and 7.25% for 2024 and 2023, respectively. The ultimate healthcare cost trend rate was 4.50% for both 2024 and 2023 and the assumption for the year the ultimate healthcare cost trend rate is reached was 2035 for both 2024 and 2023. For Canadian OPEB plans, the healthcare cost trend rate assumption for the next year was 5.06% and 5.13% for 2024 and 2023, respectively. The ultimate healthcare cost trend rate was 4.00% and the assumption for the year the ultimate healthcare cost trend rate is reached was 2040 for both 2024 and 2023.

December 31, 2024 and 2023 exclude $479 million and $628 million, respectively, of hedge fund and private equity investments that are measured at fair value using the NAV per share (or its equivalent) as a practical expedient, which are not required to be classified in the fair value hierarchy. Additionally, December 31, 2024 and 2023 exclude $7 million and $3 million of accrued liabilities, respectively.
(2)
Derivative instruments include futures contracts. The fair value and aggregate notional value of these contracts were $(1) million and $664 million at December 31, 2024, respectively, and $1 million and $393 million at December 31, 2023, respectively.

For the U.S. defined benefit plans, the discount rate assumption was 5.20%, 5.40% and 2.90% for 2024, 2023 and 2022, respectively. For the Canadian defined benefit plans, the discount rate assumption was 4.70%, 5.30% and 3.10% for 2024, 2023 and 2022, respectively. For U.S. OPEB plans, the discount rate assumption was 5.10%, 5.40% and 2.60%, for 2024, 2023 and 2022, respectively. For Canadian OPEB plans, the discount rate assumption was 4.60%, 5.30% and 3.00% for 2024, 2023 and 2022, respectively. For lump sum distributions (for U.S. qualified salaried and nonqualified plans only), the interest and mortality assumptions are the same as those mandated by the Pension Protection Act of 2006 for benefits commencing in the current year.
(2)
Determining our expected return requires a high degree of judgment. We consider actual pension fund asset performance over multiple years and current and expected valuation levels in the global equity and credit markets. Historical fund returns are used as a base and we place added weight on more recent pension plan asset performance.
(3)
For the U.S. defined benefit plans, the rate of compensation increase assumption for 2024, 2023 and 2022 was between 2.00% - 13.00% for salaried participants and was decreasing with participant age. For the Canadian defined benefit plans, the rate of compensation increase assumption for salaried participants was 1.00% - 2.75% for 2024 and 2023 and 3.25% for 2022. The rate of compensation increase assumption for hourly participants was 2.00% - 2.75% for 2024 and 2023 and 3.00% for 2022.
(4)
U.S. qualified salaried and nonqualified plans only.
(5)
For OPEB plans during 2024, the assumed weighted healthcare cost trend rate was 7.25% and 5.13% for U.S. Pre-Medicare participants and Canadian OPEB plans, respectively.

(1)
Cash and short-term investments are valued at cost, which approximates market.
(2)
Public equity investments are valued at exit prices quoted in active markets.
(3)
Fixed income investments include publicly traded corporate and government issued debt. These bonds have varying maturities, credit quality and sector exposure and are selected to align with the duration of our plan liabilities. Additionally, at December 31, 2023 our fixed income portfolio included repurchase agreements, which represent short-term borrowings to hedge against interest rate risk. We have an obligation to return the cash related to these borrowings in accordance with the agreements, which are collateralized by our government bonds. Fixed income investments are valued at exit prices quoted in active or non-active markets or based on observable inputs.
(4)
Hedge funds and related investments are privately-offered managed pools primarily structured as limited liability entities. General members or partners of these limited liability entities serve as portfolio managers and are thus responsible for the fund’s underlying investment decisions. Underlying investments within these funds may include long and short public and private equities, corporate, mortgage and sovereign debt, options, swaps, forwards and other derivative positions. These funds have varying degrees of leverage, liquidity and redemption provisions.
(5)
These investments are primarily valued based on the NAVs of the funds. These values represent the per-unit price at which new investors are permitted to invest and existing investors are permitted to exit. When NAVs as of the end of the year have not been received, we estimate fair value by adjusting the most recently reported NAVs for market events and cash flows between the interim date and the end of the year.
(6)
Private equity and related investments include both investments in private equity and investments in mezzanine, distressed, co-investments and other structures. Private equity funds generally participate in buyout and venture capital strategies through unlisted equity and debt instruments. These funds may also borrow at the underlying entity level. Mezzanine and distressed funds generally invest in the debt of public or private companies with additional participation through warrants or other equity options.
(7)
Derivative instruments include risk-mitigating futures and are valued based upon valuation statements received from each counterparty.
