Basis of Presentation The unaudited condensed consolidated financial statements of Avalon and related notes included herein have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission.

The operating results for the interim periods are not necessarily indicative of the results to be expected for the full year.
