Combined Financial Statements, page F-1 Revenue Recognition, page F-12 8. We have reviewed your response to comment 15. We continue to believe that to allow for comparability of income statement classifications with other entities, your disclosure should enable investors to understand which costs are in which captions. For additional information please also refer to the speech given by Scott Taub at the December 4, 2000 AICPA National Conference. Please disclose the types of amounts included in the cost of goods sold line item and the selling, general and administrative expense line item. In doing so, please also disclose whether you currently exclude inbound freight charges, purchasing and receiving costs, inspection costs, warehousing costs, internal transfer costs, or other costs of your distribution network in the cost of goods sold line item. With the exception of warehousing costs, if you currently exclude a portion of these costs from cost of goods sold, please disclose: * in a footnote the line items that these excluded costs are included in and the amounts included in each line item for each period presented; and * in MD&A that your gross margins may not be comparable to those of other entities, since some entities include all of the costs related to their distribution network in cost of goods sold while others like you exclude a portion of them from gross margin, including them in the selling, general and administrative expense line item. Condensed Combined Financial Statements, page F-53 Note 5 - Accounts Receivable Sales, page F-60 9. Please disclose the amount of repurchased accounts receivable for which you received payments during April, May, and June. Please also disclose the classification of such receipts in your statement of cash flows. If you have classified the receipts as an operating cash flow, please tell us the basis for that classification and disclose to readers that this is the second time that cash inflows related to the same receivables are being included in operating cash flows. As appropriate, please amend your registration statement in response to these comments. You may wish to provide us with marked copies of the amendment to expedite our review. Please furnish a cover letter with your amendment that keys your responses to our comments and provides any requested information. Detailed cover letters greatly facilitate our review.

We urge all persons who are responsible for the accuracy and adequacy of the disclosure in the filing to be certain that the filing includes all information required under the Securities Act of 1933 and that they have provided all information investors require for an informed investment decision. Since the company and its management are in possession of all facts relating to a company`s disclosure, they are responsible for the accuracy and adequacy of the disclosures they have made. Notwithstanding our comments, in the event the company requests acceleration of the effective date of the pending registration statement, it should furnish a letter, at the time of such request, acknowledging that: * should the Commission or the staff, acting pursuant to delegated authority, declare the filing effective, it does not foreclose the Commission from taking any action with respect to the filing; * the action of the Commission or the staff, acting pursuant to delegated authority, in declaring the filing effective, does not relieve the company from its full responsibility for the adequacy and accuracy of the disclosure in the filing; and * the company may not assert staff comments and the declaration of effectiveness as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States. In addition, please be advised that the Division of Enforcement has access to all information you provide to the staff of the Division of Corporation Finance in connection with our review of your filing or in response to our comments on your filing. We will consider a written request for acceleration of the effective date of the registration statement as a confirmation of the fact that those requesting acceleration are aware of their respective responsibilities under the Securities Act of 1933 and the Securities Exchange Act of 1934 as they relate to the proposed public offering of the securities specified in the above registration statement. We will act on the request and, pursuant to delegated authority, grant acceleration of the effective date.
