The New York Stock Exchange suspended trading of Westmoreland Resource Partners LP's common units on Oct. 9 following the company's bankruptcy announcement.
The exchange cited "uncertainty as to the timing and outcome of the bankruptcy process" in its decision, according to a Form 8-K filed Oct. 10.
The company, a master limited partnership of Westmoreland Coal Co., opted to not seek review of the delisting by the exchange's committee of the board of directors. Its common units are now trading on the OTC Pink Marketplace, the lowest tier of the three marketplaces, under the symbol WMLPQ.
The company's application to delist its units from the Securities and Exchange Commission is pending as well.
Westmoreland Coal, which also filed for Chapter 11 protection on Oct. 9, was delisted from the Nasdaq Stock Exchange on April 25.
