 synthetic GICs are owned by the SVF, which is part of the Master Trust. NT is the custodian for the Master Trust assets. The underlying assets of the synthetic GICs are invested in diversified fixed income and cash portfolios managed by BlackRock Financial Management, Voya Investment Management Co., J.P. Morgan Investment Management (“JPM”), Pacific Investment Management Company, PGIM (the global investment management business of Prudential Financial), and Western Asset Management Co. In addition to the diversified fixed income portfolios, GSAM oversees an allocation to a cash component, which is invested in a separately managed account, managed by JPM.

The wrap providers are each contractually obligated to pay the principal and specified crediting rate that is guaranteed to the SVF, subject to the terms, conditions and exceptions of each wrap contract. The respective crediting rates are each based on a formula agreed upon with each wrap contract issuer; each contract provides an interest rate floor of 0%. Such contract crediting rates are reset on a monthly basis while the crediting rate for the SVF is reset on a daily basis.

Certain events, including but not limited to a Plan termination or a Plan merger outside the Master Trust initiated by the Company, could limit the ability of the SVF to transact at contract value or may allow for the termination of the wrap contract at less than contract value. The Company does not believe that any events are probable of occurring that could limit the ability of the SVF to transact at contract value.

### MASTER TRUST
The Master Trust assets are invested and records are maintained by each investment fund option. Funds are allocated to the participating plans in accordance with the Plan provisions and Member allocation elections. The allocation of net assets is based on the respective number of units held by the plans’ Members as of year-end. The allocation of the changes in net assets is calculated daily based on the units held by the plans’ Members as of that day’s end.

The Plan’s interest in the Master Trust represented 100% of the Master Trust’s net assets at December 31, 2024 and 2023.

Although the Plan is the only participating plan in the Master Trust as of December 31, 2024, the Company intends to keep the Master Trust for potential future acquired plans and file a Form 5500 as a master trust.
