The Claymore/Delta Global Shipping Index ETF (Ticker: SEA) seeks investment results that correspond generally to the performance, before fees and expenses, of the Delta Global Shipping Index. The index currently consists of 30 companies within the maritime shipping industry which includes companies within the following business segments of the maritime shipping industry: companies deriving a significant portion (in excess of 80%) of their revenues from the seaborne transport of dry bulk goods and the leasing and/or operating of tanker ships, container ships, specialty chemical ships and ships that transport liquid natural gas or dry bulk goods. A modified dividend weighting mechanism is applied to constitute the final index, with higher-yielding securities based on their indicated dividend yield being more highly weighted according to a proprietary methodology. No single security weight will exceed 4% of the index at the time of each rebalance. The Index will be reconstituted annually, with rebalancing occurring quarterly.
