BCHG NAV valuation index changing to CoinDesk BCH CCIXber Reference Rate from Oct 1
--------------------------------------------------------------------------------

- Effective Oct 1, 2025, BCHG NAV will use the CoinDesk BCH CCIXber Reference Rate instead of the prior CoinDesk Bitcoin Cash Index (BCX).
- New index is a volume-weighted real-time price from Constituent Trading Platforms such as Crypto.com, Kraken, LMAX Digital, and Bitstamp.
- Index methodology includes outlier detection, inactivity adjustment, and manipulation resistance; exact algorithm is not publicly available.
- If the primary index is unavailable, the Sponsor will use a cascading fallback: Coin Metrics Secondary Index, then a Tertiary Pricing Option, then a good-faith estimate.
- No financial impact or change in Trust holdings was disclosed; the change is purely a valuation methodology update.
