3 ZXData Robustness Score is an internally developed metric to assign confidence levels to the underlying data used in constructing ZXData output metrics. The ZXData Robustness Score is calculated on a scale of 1 to 10 for each company, based on the number of executed trades, number of buy and sell orders submitted to ZX and skewness of the order book.
4 ZX Index Value is an internally developed metric that reflects secondary values for private companies using an algorithmic approach based on the values sourced from ZX and ZXData partners. The algorithm used to calculate ZX Index Values incorporates both executed transaction values and bid and ask pricing.

In June, 25% of companies with ZX Index Values showed a difference of 10% or less compared to Fund Marks, and 46% of companies with ZX Index Values showed a difference of 20% or less compared to Fund Marks. Among the companies, Neuralink, Celonis and Freenome had the highest positive variance in reported marks versus ZX Index Values. SandboxAQ, Druva and Oura Health had the highest negative variance in reported marks versus ZX Index Values.
