The Tortoise MLP ETF, ticker TMLP, aims to offer investors access to the Master Limited Partnership (MLP) sector. It achieves this by tracking a market-capitalization-weighted index comprising U.S.-domiciled and traded MLPs and limited liability companies. These entities primarily engage in the energy commodity value chain, encompassing their transportation, production, processing, or storage. For a company to qualify for index inclusion, it must be based and listed in the United States, possess a market capitalization of at least $200 million USD, and sustain an average market cap of $175 million USD over the 20 trading days preceding any rebalancing reference date. The fund principally obtains its index exposure through investments in total return swaps that reference the underlying components. Optionally, it may also directly hold up to 25% of its total assets in these constituent securities. Portfolio diversification is ensured with a 7.5% cap on individual positions and a 15% limit on holdings from any single MLP Affiliate family. The underlying index is reviewed and adjusted on a quarterly basis.
