 to the price of HBAR on the Constituent Trading Platforms calculated every 5 seconds over a 24-hour period. The Index’s algorithm is expected to reflect a five-pronged methodology to calculate the Index Price from the Constituent Trading Platforms for HBAR:

Volume Weighting: Constituent Trading Platforms with greater liquidity receive a higher weighting in each Index, increasing the ability to execute against (i.e., replicate) the Index in the underlying spot markets. The Index methodology is a volume-weighted real-time price where each Constituent Trading Platform is weighted based on its trailing 24-hour volume.

FX Conversion: The Index algorithm utilizes a volume-weighted real-time FX conversion rate for any trading activity for the relevant Stablecoin-USD pair. This normalizes all trading activity to USD denomination.

Outlier Detection Factor: The Index algorithm excludes trade data and price(s) deemed to be an outlier relative to the most recently calculated Index.

Outlier Detection Factor: The Index algorithm penalizes stale activity from any given Constituent Trading Platform. When a Constituent Trading Platform does not have recent trading data, the outdated prices and their contribution to the Index calculation are gradually reduced until they are de-weighted to 0.1%. Similarly, once trading activity at a Constituent Trading Platform resumes, the corresponding weighting for that Constituent Trading Platform will no longer be penalized.

Manipulation Resistance: In an effort to determine and prioritize the most significant Constituent Trading Platforms (i.e., those that are likely to have the most impact on price discovery) for a given asset, the Index Provider conducts a Constituent Trading Platform selection and review process, which seeks to identify the highest-ranking Constituent Trading Platforms based on both qualitative and quantitative factors. The qualitative review includes legal and regulation, data provision, security, trade monitoring, market quality,

and negative events policy, among others. The quantitative review includes review of trading activity for the asset on the given Constituent Trading Platform.

The Index Provider re-evaluates the weighting algorithm on a periodic basis, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The exact methodology to calculate the Index Price is not publicly available. Still, the Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms.
