WOOD tracks the S&P Global Timber & Forestry Index, a cap-weighted index of the 25 largest forestry firms around the world. The fund starts with all the eligible securities from the S&P Global BMI that are classified under agriculture, forestry, homebuilding, and paper industry. To determine industry relevance, each company will be given an exposure score based on its business description and most recent reported revenue. The 25 largest companies with an exposure score of 1 will be selected for inclusion, however, if fewer than 25 companies have an exposure score of 1, the fund will select the largest companies with 0.5 exposure score until the portfolio contains a total of 25 constituents. Selected securities will then be weighted based on its exposure score with constraints such that securities with an exposure score of 1 are capped at 8% and those with 0.5 exposure score are capped at 4%. The index rebalancing occurs semi-annually.
