The law firm of Wohl & Fruchter LLP has commenced an investigation into whether XTO Energy Inc. (XTO) has systematically failed to pay amounts due to Hugoton Royalty Trust (the Trust) (HGT) in breach of the net overriding royalty conveyances (the conveyances) that form the principal assets of the Trust.
"If you read the last 10Q you'd know that" the last quarterly report disclosed that a lawsuit was already filed Sept 12 by a unitholder on behalf of the Trust (not a class action) against XTO for all the same reasons (and more).
Check out the last line in the news article you quote "This release may be deemed to constitute attorney advertising". I think Wohl and Frucher smell a big settlement and are fishing for clients. Appears to be a securites lawsuit "ambulance chaser".
If Wohl and Fruchter's "investigation" had done even an initial investigation they'd have realized they are 6 months late to the party and that the lawsuit already filed would take precidence on anything they might do. They'd also find that the law firm that is already involved is a succesful law firm experienced in this type of law.
