Basis of Presentation

The Company was acquired on August 19, 2011 through a merger transaction with IVD Acquisition Corporation (“Merger Sub”), a wholly owned subsidiary of IVD Intermediate Holdings B, Inc. (the “Parent”). The Parent is a wholly owned indirect subsidiary of IVD Holdings, Inc. which was formed by investment funds affiliated with TPG Capital, L.P. (“TPG Capital”). The acquisition was accomplished through a merger of the Merger Sub with and into Immucor, with Immucor being the surviving company (the “Acquisition”). As a result of the merger, Immucor became a wholly owned subsidiary of Parent. Prior to August 19, 2011, Immucor operated as a public company with common stock traded on the NASDAQ Stock Market.

Immucor continued as the same legal entity after the Acquisition.  However, a new accounting basis was established upon treating the merger as a business combination. The accompanying unaudited consolidated statements of operations and comprehensive loss are presented for the quarter ended November 30, 2012 and the quarter ended November 30, 2011.  In addition, the accompanying unaudited consolidated statements of operations, comprehensive loss and cash flows are presented for the six months ending November 30, 2012 and November 30, 2011, which is presented in two periods: the Predecessor fiscal 2012 period (June 1, 2011 to August 19, 2011) and the Successor fiscal 2012 period (August 20, 2011 to November 30, 2011), which relate to the period preceding the Acquisition and the period succeeding the Acquisition during the prior fiscal year. Although the accounting policies followed by the Company are consistent for the Predecessor and Successor periods, financial information for such periods has been prepared under two different historical-cost bases of accounting and is therefore not comparable. The results of the periods presented are not necessarily indicative of the results that may be achieved for the year ending May 31, 2013, or any other period.

The accompanying consolidated financial statements are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information, and the Securities and Exchange Commission’s (“SEC”) instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation of the unaudited consolidated financial statements have been recorded in the interim periods presented. These unaudited consolidated financial statements should be read in conjunction with the Company’s audited, consolidated financial statements and related notes for the year ended May 31, 2012, included in the Company’s Annual Report on Form 10-K filed on July 27, 2012.
