(the "Company") for the year ended September 30, 2005, the Company's independent registered public accounting firm, Grant Thornton LLP ("Grant Thornton"), identified certain proposed adjustments in the Company's financial statements for the year ended September 30, 2005. Upon considering this information, the Company's management determined that adjustments relating to lease accounting also affected the Company's interim financial statements and other financial information for the quarters ended March 31, 2005 and June 30, 2005, and the Audit Committee of the Board of Directors of the Company authorized management to amend and restate the financial statements and other financial information for these interim periods. In light of the restatement, investors should no longer rely on the Company's previously filed financial statements and other financial information for each of the Company's fiscal quarters ended March 31, 2005 and June 30, 2005. Background ---------- The Company has agreements with the Port of Walla Walla, Washington to lease two operating facilities, the lease on one of which expires on December 31, 2005. The Company has undertaken in 2005 to consolidate its operations into one facility by the end of calendar 2005 and modified one of its leases to add additional leased space and to extend the lease term through 2020. As a result of the consolidation of facilities and expiration of the lease on one operating facility, the Company reduced deferred rent credits over the remaining term of the expiring lease beginning in the second quarter of fiscal 2005 and continuing through the end of fiscal 2005. However, management has subsequently concluded that (a) the accounting treatment to be used for the deferred rent credits relating to the expiring lease is to amortize the credits over the remaining term of the continuing operating facility lease; (b) the Company's quarterly reports previously filed with respect to the fiscal quarters ended March 31, 2005 and June 30, 2005 should be restated; and (c) no reliance should be placed on the Company's previously issued financial statements for the quarters ended March 31, 2005 and June 30, 2005. As a result of these conclusions and the authorization by the Audit Committee, the Company will file restated financial statements for the quarterly periods ended March 31, 2005 and June 30, 2005 as amendments to its periodic reports filed with the Securities and Exchange Commission as soon as practicable. Accordingly, the previously issued financial statements for the quarterly periods ended March 31, 2005 and June 30, 2005 should no longer be relied upon. The effect of the restatement will be to increase rental expense for each of the last three quarterly interim periods of 2005 and to reduce net earnings for such interim periods and fiscal 2005 by approximately $360,000 before income taxes. In addition, the adoption of the revised accounting treatment will be to reduce rental expense in future periods during the existence of the continuing operating facility lease. The following table sets forth the effect of the restatement on the Company's net earnings for the fiscal quarters ended March 31, 2005 and June 30, 2005: Quarter ended March 31, 2005 June 30, 2005 -------------- ------------- Net earnings - as restated $ 62 $2,646 Net earnings - as reported $ 167 $2,709 Net earnings per share (basic) - as restated $0.01 $ 0.52 Net earnings per share (basic) - as reported $0.03 $ 0.53 Net earnings per share (diluted) - as restated $0.01 $ 0.51 Net earnings per share (diluted) - as reported $0.03 $ 0.52 The members of the Audit Committee discussed the above-referenced matters with Grant Thornton and, subsequent to such discussion, reviewed the matters discussed in this report.
