(a)North American Companies represents U.S. and Canadian large cap equity funds, which are managed to track their respective benchmarks (FTSE All-World USA Index and FTSE All-World Canada Index).

(b)Global Equity represents actively managed global equity funds, taking a top-down strategic view on the different regions by analyzing companies based on fundamentals, market-driven, thematic and quantitative factors to generate alpha.

(c)U.K. Government Gilt Index represents U.K. government issued fixed income investments which are passively managed to track their respective benchmarks.

(d)LDI seeks to invest in fixed income securities that collectively closely match those found in discount curves used to value the plan's liabilities.

(e)Multi-asset seeks an attractive risk-adjusted return by investing in a diversified portfolio of strategies, including equities and fixed income.

(f)The Buy-in Contracts ("Contract" or "Contracts") represent assets held by plans, whereby the cost of providing benefits to plan participants is funded by the Contract. The Contracts are held by the plans for the benefit of plan participants in the Netherlands and U.K. The fair value of these assets are based on the current present value of accrued benefits and will fluctuate based on changes in the obligations associated with covered plan members as well as the assumptions used in the present value calculation. The fair value of asset held in the Netherlands Contract as of January 1, 2020 was $25.9 million, with contributions and currency adjustments resulting in a fair value of $27.4 million at December 31, 2020. Similarly, The fair value of asset held in the U.K. plan Contract as of January 1, 2020 was $28.6 million, with contributions and currency adjustments resulting in a fair value of $31.8 million at December 31, 2020.

(g)Includes assets held by plans outside the United Kingdom, the Netherlands and Canada. Details have not been provided due to immateriality.
