Through the Master Trust agreement, an investment account was initially established to accommodate the investment assets of the Plan and other Company sponsored retirement plans. Within the Master Trust, the investment assets of the Plan reside in the ITW Defined Contribution Plans' Investment Account (the "DC Investment Account"). Plan investments and investment income reported in the Plan's financial statements represent the Plan's interest in the Master Trust's net assets and investment income and expenses.

Each participating plan's interest in the Master Trust is based on the aggregate account balances of the participants in the respective participating plan. The Master Trust specifically identifies contributions, benefit payments, and plan-specific expenses attributable to each participating plan. Investment gains (losses) are allocated to each participating plan in the Master Trust on a daily basis based on each plan's divided interest in the Master Trust.

The net assets in the DC Investment Account and the Plan's interest in the Master Trust account as of December 31, 2025 and 2024 were as follows:
