PAWZ is the first fund centered on companies related to pet ownership. To be selected, a stock must fit one of eight RBICS sub-industries: pet food manufacturing, pet supplies manufacturing, pet and pet supply stores, veterinary pharmaceuticals, veterinary diagnostics, veterinary product distributors, veterinary services, and internet pet and supply retail. Constituents may be domiciled in any country. PAWZ is weighted in two tiers: a core tier of companies deriving more than 50% of their revenue from the listed sub-industries and a non-core tier of companies with over in revenue, but less than 50% of those revenues from the above groups. The core tier gets 85% of fund assets and the non-core tier gets the remainder. Within each tier, individual weights are determined by market cap. The index has an annual reconstitution and a monthly rebalance.
