We note you present the operating results of Lawson on a GAAP and non-GAAP basis. It appears you present financial information that combines post-merger results and unadjusted pre-merger results. Please explain how your presentation of combined results without reflecting all relevant and significant pro forma adjustments required by Article 11 of Regulation S-X is appropriate or revise. Lawson Segment, page 31 4. Where you describe two or more business reasons that contributed to a material change in a financial statement line item between periods, please quantify, where possible, the extent to which each change contributed to the overall change in that line item. As examples, we note your disclosure that the increase in revenue was driven by price increases, increased quantity volumes and strengthening sales. The increase in selling, general and administrative expenses was driven by compensation expense, higher severance, and higher amortization expense, partially offset by lower costs related to the Mergers and stock-based compensation. In each case the disclosures do not quantify any of the factors. See Item 303 of Regulation S-K and SEC Release No. 34-48960. We remind you that the company and its management are responsible for the accuracy and adequacy of their disclosures, notwithstanding any review, comments, action or absence of action by the staff. Please contact Scott Stringer at 202-551-3272 or Adam Phippen at 202-551-3336 if you have questions regarding comments on the financial statements and related matters.
