5. INTEREST IN SYNTHETIC GUARANTEED INVESTMENT CONTRACTS

Synthetic guaranteed investment contracts consist of fully benefit-responsive wrapper contracts that provide specified interest rates. Realized and unrealized gains and losses on the underlying assets are not reflected immediately in the net assets of the Plan, but are amortized as adjustments to the future interest-crediting rate over a period equal to or less than the duration of the underlying assets. Primary variables affecting the future crediting rate of the wrapper contracts include the current yield of underlying assets, the duration of underlying assets, and the difference between the market value and contract value of underlying assets.

Investments held in synthetic guaranteed investment contracts (at contract value) totaled $3.2 billion and $3.5 billion as of December 31, 2024 and 2023, respectively.

Certain events, such as Plan termination or a plan merger initiated by the Plan sponsor, may limit the ability of the Plan to transact at contract value or may allow for the termination of the wrapper contract at less than contract value. Plan management believes that the occurrence of events that may limit the ability of the Plan to transact at less than contract value is not probable.

#### 6. THIRD PARTY BORROWINGS
The DC Master Trust participates in a securities lending program with State Street through the separately managed Stable Value Account. The program allows State Street to loan securities, which are assets of the DC Master Trust, to approved borrowers. Such assets could be subject to sale restrictions in the event security lending agreements are terminated and the securities have not been returned to the DC Master Trust. DC Master Trust assets on loan to third-party borrowers under security lending agreements are as follows:
