The Investment Manager will seek to achieve the objective through the active management of commodities exposure against the customized equal sector-weighted S&P Goldman Sachs Commodities Index (the "Index"). The Fund will be managed in compliance with the principle of risk diversification. The Index is a composite index of commodity sector returns representing unleveraged, long-only investment in commodity futures that is broadly diversified across the spectrum of commodities. Each calendar quarter, the Benchmark is rebalanced to be equal weighted among the following four sectors: energy, industrial metals, precious metals, and agriculture and livestock (i.e., each sector will represent 25% of the Index after rebalancing). Within each sector, each commodity remains weighted proportionately to its weight in the production-weighted S&P GSCI. For example, if crude oil accounts for half of the energy sector weight within the production-weighted S&P GSCI, then it will also account for half of the energy sector weight within the Index.
