Further, the investigation did not reveal any inaccuracies in our consolidated financial statements resulting from these transactions.

On February 20, 2015, the Board of Directors waived any potential inconsistencies with our Code of Conduct and Ethics arising from the transactions identified in the investigation. Also, the Audit Committee approved the related party nature of such transactions to the extent it had not previously approved such transactions. The Board of Directors and Audit Committee specified that such waiver and approval would have retroactive effect to the date of commencement of the transactions covered by such waiver and approval. We have incurred approximately $1.8 million of professional service fees during the course of this investigation.
