In some of our comments, we may ask you to provide us with information so we may better understand your disclosure. After reviewing this information, we may raise additional comments. Please understand that the purpose of our review process is to assist you in your compliance with the applicable disclosure requirements and to enhance the overall disclosure in your filing. We look forward to working with you in these respects. We welcome any questions you may have about our comments or any other aspect of our review. Feel free to call us at the telephone numbers listed at the end of this letter. Form 10-K for the Fiscal Year Ended January 31, 2005 Item 6 - Selected Financial Data, page 19 1. In future annual filings, please present income (loss) from continuing operations per common share as required by Item 301 of Regulation S-K. Management`s Discussion and Analysis of Financial Condition and Results of Operations, page 21 Unallocated Corporate Expenses, page 29 2. Please supplementally tell us which expenses are included in unallocated corporate expenses and your rationale for categorizing these expenses in this manner in lieu of allocating them to a reportable segment. Financial Statements, page 41 Note 9 - Income Taxes, page 64 3. Reference is made to the federal income tax matters referred to in the last paragraph of Note 9. If these matters have not yet been resolved, please tell us the current status, the nature of the overall issue, the specific issues causing the delay in resolution, the actions necessary on the part of the Internal Revenue Service and/or the company, the amount of potential exposure and the amount of any accruals. Tell us the basis for your belief that the Internal Revenue Service will grant relief and that the ultimate outcome of the federal income tax return audits will not result in a material impact on the your consolidated results of operations or financial position. It is unclear from your disclosure whether you hold the same belief with respect to the impact of the resolution on your cash flows. Exhibit 31 - Section 302 Certifications 4. Please revise the section 302 certifications in your Form 10-K for fiscal year ended January 31, 2005 and Forms 10-Q for fiscal quarters ended April 30, 2005 and July 31, 2005 to conform to the exact wording as indicated in Item 601(B)(31) of Regulation S-K. Specifically refer to certification #4 and include: * the reference in the lead-in sentence to "internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f))" in both Forms 10-K and 10-Q; and * in your Form 10-K, paragraph (b) should state that you have "designed such internal control over financial reporting, or caused such internal control over financial reporting to be designed under your supervision...." In doing so, please re-file your Forms 10-K and 10-Q. Form 10-Q for the Fiscal Quarter Ended July 31, 2005 Note 8 - Contingencies, page 15 5. We note your disclosure included in the above referenced note as well as in Item 3 and Note 15 of your Form 10-K for the year ended January 31, 2005. In neither case is a discussion of any specific matter provided. Your disclosure indicates that "the resolution of any of these matters may have an impact on the financial results for the period in which the matter is resolved." We assume that this statement implies a "material impact" on the financial results. However, you continue and state that "the Company believes that the ultimate disposition of these matters, will not, in the aggregate, have a material adverse effect upon its business or consolidated financial position, results of operations or cash flow." The disclosure provided, in some respects, appears contradictory. Please clarify, as appropriate. Tell us about any matters whose ultimate resolution is at least reasonably possible to have a material impact to you. You should include all disclosures required by SFAS No. 5, Accounting for Contingencies. In addition, management`s discussion and analysis should include a discussion of known events and uncertainties using the two-part assessment discussed in section 501.02 of the SEC Codification of Financial Reporting Policies. *	*	* Please respond to these comments within 10 business days, or tell us when you will provide us with a response.
