## Questions

### What is the exact legal mandate of the trust?

The trust is governed by a combination of Nuclear Regulatory Commission decommissioning-funding rules and, for the Seabrook component, oversight by New Hampshire's Nuclear Decommissioning Financing Committee. Its sole permitted use of funds is the future radiological decommissioning of Seabrook Station and Millstone Unit 3.

### Who makes investment decisions for the trust?

Day-to-day treasury and financial oversight falls to MMWEC's finance group under Haley Pedruczny. Ultimate investment-policy authority rests with the NDFC for the Seabrook portion, while the Millstone decommissioning funding is managed by the plant's lead owner, Dominion Nuclear Connecticut, Inc., with MMWEC as a minority participant.

### Can the trust take risk to accelerate funding, or is it strictly liability-matching?

Because the trust exists to satisfy a regulatory funding requirement with a known terminal date, its structure strongly favors liability matching. It does not maintain a mandate to seek excess returns, and its public descriptions contain no reference to opportunistic or alpha-seeking strategies.

### How is the trust related to MMWEC's other financial activities?

The trust is a fiduciary activity of MMWEC, legally distinct from the agency's pooled-loan program, power-supply contracts, and generation-asset operations. Its assets cannot be commingled with MMWEC's general funds or used to support operating obligations of member municipal light plants.
