ECA Marcellus Trust I

ECA Marcellus Trust I is a U.S. royalty trust that holds overriding royalty interests in natural gas properties in the Marcellus Shale. It does not operate wells or sell gas itself; instead, it receives a share of production proceeds from underlying properties and distributes substantially all cash receipts to unitholders.
