Also, the auditors seemed to have other concerns in the same 10-K:
"The following material weakness has been identified and included in management’s assessment: A lack of controls, or ineffective application of controls related to the initiation, recording and processing of certain transactions related to preparation and review of documentation to support financial statement close procedures. This material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2008 financial statements, and this report does not affect our report dated March 30, 2009 on those financial statements.
In our opinion, because of the effect of the material weakness described above on the achievement of the objectives of the control criteria, Tri-Valley Corporation has not maintained effective internal control over financial reporting as of December 31, 2008, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO)."
You would have to wonder if the Opus investors have ever asked what happened to their funds and how they have been applied all along.
The following is a really old (1996 bankruptcy time) solicitation for shareholders votes by a group who tried to remove the (then) board. There were some pretty serious accusations levelled. Hopefully things have changed.
