In some of our comments, we may ask you to provide us with supplemental information so we may better understand your disclosure. After reviewing this information, we may or may not 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 on 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 YEAR ENDED DECEMBER 31, 2004 Comments applicable to your overall filing 1. Where a comment below requests additional disclosures or other revisions to be made, please show us in your supplemental response what the revisions will look like. These revisions should be included in your future filings. Item 7 - Management`s Discussion and Analysis 2004 Compared to 2003, page 23 2. Please discuss in greater detail the business reasons for the changes between periods in revenues, gross profit, and selling, general and administrative expenses. In doing so, please disclose the amount of each significant change in line items between periods and the business reasons for it. In circumstances where there is more than one business reason for the change, attempt to quantify the incremental impact of each individual business reason discussed on the overall change in the line item. Please show us what your revised MD&A for 2004 as compared to 2003 will look like. See Item 303(a)(3) of Regulation S-K and Financial Reporting Codification 501.04. Liquidity and Capital Resources, page 31 3. Please disclose the interest rates and fees that apply to your credit facility. 4. Please retitle what you currently call EBITDA, since you are including other non-cash charges in this measure. See Question 14 of our FAQ Regarding the Use of Non-GAAP Financial Measures dated June 13, 2003. In addition, please present a reconciliation of what you currently call EBITDA to the most directly comparable financial measure calculated and presented in accordance with GAAP. See Item 10(e)(i)(B) of Regulation S-K. 5. Please revise your table of contractual cash obligations to include the estimated interest payments on your debt. Because the table is aimed at increasing transparency of cash flow, we believe these payments should be included in the table. Please also disclose any assumptions you made to derive these amounts. Please also revise your table so that the sum of your contractual obligations for each period and in total appears at the bottom of the table. Item 8 - Financial Statements Note 2 - Summary of Significant Accounting Policies, page 48 6. Please disclose the types of expenses that you include in the cost of services line item and the types of expenses that you include in the selling, general and administrative expenses line item. Please also disclose whether you include inbound freight charges, purchasing and receiving costs, inspection costs, warehousing costs, internal transfer costs, and the other costs of your distribution network in the cost of services line item. With the exception of warehousing costs, if you currently exclude a portion of these costs from cost of services, 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 services and others like you exclude a portion of them from gross margin, including them instead in a line item, such as selling, general and administrative expenses. Inventories, page 48 7. Please disclose your major classes of inventory, such as raw materials, work in process and finished goods, as well as the corresponding amounts in each class. See Rule 5-02(6)(a) of Regulation S-X. Property and Equipment, page 48 8. You disclose that gains and losses resulting from the retirement or disposition of property and equipment are recognized in other income (expense). If the property and equipment that is retired or disposed of is not a component of an entity, the resulting gains and losses should be included in operating income. See paragraph 45 of SFAS 144. Please revise accordingly. Goodwill, page 49 9. You disclose that goodwill represents the excess of the aggregate purchase price over the fair value of the net tangible assets acquired. Please clarify that the determination of goodwill not only takes into consideration the value of net tangible assets acquired, but also intangible assets acquired that are separate from goodwill. Revenue Recognition, page 49 10. You disclose that as you perform under your percentage of completion projects, such costs are measured as incurred, compared to total estimated costs to complete the project, and a corresponding proportion of contract revenue is recognized. Please disclose when you include actual costs incurred in your revenue recognition computations. Are products and materials included in the computation when they arrive on site? Do you wait until they are actually installed? Do you wait until they are both installed and a key milestone has been met? Self-Insurance Liabilities, page 50 11. Please disclose the extent of your self-insurance in each area that you are self-insured. Please also disclose whether or not you have excess loss insurance and, if so, the amounts at which this insurance coverage begins in each area. Note 11 - Commitments and Contingencies, page 69 12. Please disclose how you account for (a) step rent provisions and escalation clauses and (b) capital improvement funding and other lease concessions, which may be present in your leases. Paragraph 5.n. of SFAS 13, as amended by SFAS 29, discusses how lease payments that depend on an existing index or rate, such as the consumer price index or the prime interest rate, should also be included in your minimum lease payments. If, as we assume, they are taken into account in computing your minimum lease payments and the minimum lease payments are recognized on a straight-line basis over the minimum lease term, the note should so state. If our assumption is incorrect, please tell us how your accounting complies with SFAS 13 and FTB 88-1. Note 12 - Stockholders` Equity, page 70 Earnings Per Share, page 72 13. Please tell us why you included the effect of shares issuable related to warrants in your calculation of diluted shares for 2003, given that you had a loss from continuing operations during the year. See paragraph 16 of SFAS 128. FORM 8-K FILED MARCH 3, 2005 14. Your presentation of a complete set of non-GAAP income statements gives too much prominence to these non-GAAP amounts. Please remove the non-GAAP income statements from your Form 8-K and instead discuss the business reasons for changes between periods by disclosing the impact that each of these items had on the overall change in the GAAP line item. Naturally, you may include individual non-GAAP measures in a more limited manner as long as you reconcile them to the most comparable GAAP measures and discuss how you use them. See Item 10(e)(i) of Regulation S-K. * * * * Please respond to these comments within 10 business days, or tell us when you will provide us with a response.
