    "supporting_data": "The WisdomTree California Carbon ETC is classified as complex under MiFID II due to several key factors: 1) It uses synthetic replication via swaps to track carbon futures contracts, which introduces counterparty risk and requires understanding of derivative mechanics. 2) The underlying index (Solactive California Carbon Rolling Futures Total Return Index) involves rolling futures contracts, which are subject to contango/backwardation effects that may not be easily understood by retail investors. 3) While fully collateralised, the product still carries counterparty risk from swap agreements. 4) The PRIIPs KID includes a comprehension warning ('not simple and may be difficult to understand'), which is a strong indicator of complexity under MiFID II. 5) The fact sheet confirms the use of fully funded collateralised swaps, which while mitigating some risk, still represents a complex structure. The absence of leverage or inverse exposure does not negate the complexity from the synthetic structure and underlying index mechanics. The confidence level is 85% due to the clear synthetic replication and complex index tracking, though the fully collateralised nature slightly mitigates the complexity."
