Rigrodsky & Long, P.A. Announces Investigation Of Niska Gas Storage Partners LLC (NYSE: NKA) Buyout

Rigrodsky & Long, P.A. announces that it is investigating potential legal claims against the board of directors of Niska Gas Storage Partners LLC (“Niska” or the “Company”) (NYSE: NKA) regarding possible breaches of fiduciary duties and other violations of law related to the Company’s entry into an agreement to be acquired by Brookfield Infrastructure (“Brookfield”), in a transaction valued at approximately $911 million.

Under the terms of the agreement, unitholders of Niska will receive $4.225 in cash for each unit of Niska they own.
