operating assets and liabilities of our Scanalytics business for net proceeds of approximately $446,000. Accordingly, we have classified the Scanalytics business as a &#147;discontinued operation&#148; in accordance with the guidance provided in FAS
No. 144. This change (technically a restatement to the extent it affects previously reported results) will be reflected in our financial statements for the fiscal years ended September 30, 2003, 2004 and 2005. The re-characterization of the
Scanalytics business as a discontinued operation has no effect on our previously reported net income for any fiscal period. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P> <P
STYLE="margin-top:0px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">Our financial statements for fiscal 2003 were audited by Grant Thornton LLP. The restatement of our financial statements for fiscal 2003 solely to reflect the
characterization of Scanalytics as a discontinued operation requires that an independent auditor issue a new report on those financial statements. Grant Thornton was notified of this matter on December 19, 2005, and has advised us that it cannot
commence the work needed to reissue its report by the due date of our Annual Report on Form 10-K, due in part to the need to verify that it is still independent with respect to CSP Inc. If we or Grant Thornton determine that the firm is not
independent with respect to CSP Inc., or if Grant Thornton declines to audit the restated financial statements, we will have to engage another auditor with respect to our financial statements for fiscal 2003. </FONT></P> <P
