The accompanying condensed consolidated financial statements have not been audited by an independent registered public accounting firm in accordance with standards of the Public Company Accounting Oversight Board (United States) but, in the opinion of management, such financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the Company’s financial position and results of operations.
