## Questions

### What is the source of the trust's assets?

The trust is funded by contributions collected from San Diego Gas & Electric customers through their utility rates. These funds are designated exclusively for the future decommissioning of SDG&E's 20% share of the San Onofre Nuclear Generating Station.

### Who oversees the trust's investment and withdrawal activity?

The California Public Utilities Commission holds regulatory authority over the trust. SDG&E must obtain CPUC approval for withdrawals and for any material changes to the investment strategy, ensuring the assets are managed prudently and solely for decommissioning purposes.

### Which assets are held within the trust?

Known allocations include a municipal bond portfolio and commodity exposures. The trust operates under IRS Section 468A qualification, which restricts investments to a conservative mix of public securities, fixed-income instruments, and certain permissible commodities.

### Does the trust make direct venture capital or private equity investments?

No. The trust is a liability-driven pool that does not pursue venture capital, private equity, or direct company investments. Its mandate is structured around capital preservation and scheduled withdrawals for nuclear decommissioning milestones.

### How much capital does the trust currently manage?

The trust has not publicly disclosed its current assets under management. SDG&E reports trust-related balances in aggregate regulatory filings, but no recent standalone AUM figure is available.
