New York Stock Exchange Suspends Trading of Whiting USA Trust I Units; Trust Expects Trading to Move to OTC

Whiting USA Trust I (NYSE: WHX) today announced that the Trust units would cease trading on the New York Stock Exchange (the “NYSE”) effective before market open on February 17, 2015. The NYSE informed the Trust today that the Trust was not in compliance with the NYSE’s continued listing standards, which requires that the average closing price of the Trust units cannot be less than $1.00 per share over a period of 30 consecutive trading days. Under the NYSE delisting procedures, the Trust has the right to appeal such decision, but the Trust does not intend to do so. The Trust expects the Trust units to transition to OTC Pink, operated by OTC Markets Group, effective with the opening of trading on February 17, 2015. However, there is no assurance that an active market in the Trust units will develop on OTC Pink.
