URNJ tracks an index of global small cap companies that derive at least 50% of their revenues and/or assets from mining, exploration, development, and production of uranium. Such companies are assigned an aggregate weight of 82.5% of the index. The remaining portion of the index includes companies that hold physical uranium, own uranium royalties, or engage in other, non-mining activities that support the uranium mining industry, primarily those in infrastructure and labour. Securities within each portion are market-cap weighted. Securities are screened through a review of industry publications, sell side research, and fundamental research, as well as meetings with management. Reconstitution and rebalancing of the portfolio is done on a semi-annual basis in March and September. The fund may engage in securities lending.
