RISK FACTORS

       You should consider carefully, in addition to the other information contained in this prospectus, the following factors before deciding whether to invest in notes.

Risks Relating to Our Business

Our debt agreements contain restrictions that may limit our ability to operate our business.

       Our credit facilities and the indenture governing the notes contain, and any of our future debt agreements may contain, certain covenant restrictions that limit our ability to operate our business, including restrictions on our ability to:

       Our credit facilities also require us to maintain specific earnings to fixed expenses and debt to earnings ratios and to meet minimum net worth requirements. In addition, our revolving credit facilities contain additional affirmative and negative covenants. Our ability to comply with these covenants is dependent on our future performance, which will be subject to many factors, some of which are beyond our control, including prevailing economic conditions.

       As a result of these covenants, our ability to respond to changes in business and economic conditions and to obtain additional financing, if needed, may be significantly restricted, and we may be prevented from engaging in transactions that might otherwise be beneficial to us. In addition, our failure to comply with these covenants could result in a default under WESCO International’s convertible debentures, the notes and our other debt, which could permit the holders to accelerate such debt. If any of our debt is accelerated, we may not have sufficient funds available to repay such debt.

If the financial condition of our customers declines, our credit risk could increase.

       In light of the financial stresses within the worldwide automotive industry, certain automakers and tier-one mirror customers have already declared bankruptcy or may be considering bankruptcy. Should one or more of our larger customers declare bankruptcy, it could adversely impact the collectibility of our accounts receivable, bad debt expense and net income.

Downturns in the electrical distribution industry have had in the past, and may in the future have, an adverse effect on our sales and profitability.

       The electrical distribution industry is affected by changes in economic conditions, including national, regional and local slowdowns in construction and industrial activity, which are outside our control. Our operating results may also be adversely affected by increases in interest rates that may lead to a decline in economic activity, particularly in the construction market, while simultaneously resulting in higher interest payments under our revolving credit facility. In addition, during periods of economic slowdown such as the one we recently experienced, our credit

An increase in competition could decrease sales or earnings.

       We operate in a highly competitive industry. We compete directly with national, regional and local providers of electrical and other industrial MRO supplies. Competition is primarily focused in the local service area and is generally based on product line breadth, product availability, service capabilities and price. Other sources of competition are buying groups formed by smaller distributors to increase purchasing power and provide some cooperative marketing capability.

       Some of our existing competitors have, and new market entrants may have, greater financial and marketing resources than us. To the extent existing or future competitors seek to gain or retain market share by reducing prices, we may be required to lower our prices for current services, thereby adversely affecting financial results. Existing or future competitors also may seek to compete with us for acquisitions, which could have the effect of increasing the price and reducing the number of suitable acquisitions. In addition, it is possible that competitive pressures resulting from industry consolidation could affect our growth and profit margins compared to the industry.

Loss of key suppliers or lack of product availability could decrease sales and earnings.

       Most of our agreements with suppliers are terminable by either party on 60 days’ notice or less. Our ten largest suppliers in 2005 accounted for approximately 34% of our purchases for the period. Our largest supplier in 2005 was Eaton Corporation, through its Eaton Electrical division, accounting for approximately 12% of our purchases. The loss of, or a substantial decrease in the availability of, products from any of these suppliers, or the loss of key preferred supplier agreements, could have a material adverse effect on our business. Supply interruptions could arise from shortages of raw materials, labor disputes or weather conditions affecting products or shipments, transportation disruptions, or other reasons beyond our control. In addition, certain of our products, such as wire and conduit, are commodity-price-based products and may be subject to significant price fluctuations which are beyond our control. An interruption of operations at any of our distribution centers could have a material adverse effect on the operations of branches served by the affected distribution center. Furthermore, we cannot be certain that particular products or product lines will be available to us, or available in quantities sufficient to meet customer demand. Such limited product access could cause us to be at a competitive disadvantage.

Acquisitions that we may undertake would involve a number of inherent risks, any of which could cause us not to realize the benefits anticipated to result.

       We have historically expanded our operations through selected acquisitions of businesses and assets. Acquisitions involve various inherent risks, such as:

       Any one or more of these factors could cause us not to realize the benefits anticipated to result from the acquisition of businesses or assets.

       As of June 30, 2006, our goodwill and other intangible assets amounted to $631.9 million, net of accumulated amortization. To the extent we do not generate sufficient cash flows to recover the net amount of any investments in goodwill and other intangible assets recorded, the investment could be considered impaired and subject to write-off. We expect to record further goodwill and other intangible assets as a result of future acquisitions we may complete. Future amortization of such other intangible assets or impairments, if any, of goodwill or intangible assets would adversely affect our results of operations in any given period.

A disruption of our information systems could increase expenses, decrease sales or reduce earnings.

       A serious disruption of our information systems could have a material adverse effect on our business and results of operations. Our computer systems are an integral part of our business and growth strategies. We depend on our information systems to process orders, manage inventory and accounts receivable collections, purchase products, ship products to our customers on a timely basis, maintain cost-effective operations and provide superior service to our customers.

Our business may be harmed by required compliance with anti-terrorism measures and regulations.

       Following the 2001 terrorist attacks on the United States, a number of federal, state and local authorities have implemented various security measures, including checkpoints and travel restrictions on large trucks, such as the ones that we and our suppliers use. If security measures disrupt or impede the timing of our suppliers’ deliveries of the product inventory we need or our deliveries of our product to our customers, we may not be able to meet the needs of our customers or may incur additional expenses to do so.

Risks Relating to the Notes

We have outstanding consolidated indebtedness of approximately $199.1 million as of June 30, 2006. This amount of indebtedness could adversely affect our business, financial condition and results of operations and our ability to meet our payment obligations under the notes and our other debt.

       As of June 30, 2006, we had approximately $199.1 million of outstanding consolidated debt. This level of our debt and the related debt service requirements could have significant consequences on our future operations, including:

       Any of the above-listed factors could have an adverse effect on our business, financial condition and results of operations and our ability to meet our payment obligations under the notes and our other debt.

       Our ability to meet our payment and other obligations under our debt instruments depends on our and our subsidiaries’ ability to generate significant cash flow in the future. This, to some extent, is subject to general economic, financial, competitive, legislative and regulatory factors as well as other factors that are beyond our control. We cannot assure you that our business will generate cash flow from operations, or that future borrowings will be available to us under our credit facilities or otherwise, in an amount sufficient to enable us to meet our payment obligations under our senior subordinated indebtedness and our other debt and to fund other liquidity needs. If we or our subsidiaries are not able to generate sufficient cash flow to service our debt obligations, we may need to refinance or restructure our debt, including the notes, sell assets, reduce or delay capital investments, or seek to raise additional capital. If we are unable to implement one or more of these alternatives, we may not be able to meet our payment obligations under the notes and our other debt.

Despite our current levels of indebtedness, we may incur substantially more debt, which could further exacerbate the risks associated with our substantial indebtedness.

       Although our credit facilities contain, and the indenture regarding the notes contains, restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of qualifications and exceptions, and the indebtedness incurred in compliance with these restrictions could be substantial. Also, these restrictions do not prevent us from incurring obligations that do not constitute “indebtedness” as defined in the relevant agreement. If new debt is added to our current debt levels, the related risks that we now face could intensify. At June 30, 2006, we had approximately $275 million in available borrowing capacity under our credit facilities. All borrowings under our credit facilities are senior to the notes.

The notes are unsecured subordinated obligations.

       Our obligations under the notes are unsecured senior subordinated obligations and are subordinated to all of our existing and future senior indebtedness and effectively subordinated to our existing and future secured indebtedness to the extent of the value of the related collateral. Although the indenture contains limitations on the amount of additional indebtedness which we and our subsidiaries may incur, under certain circumstances, the amount of such indebtedness could be substantial, and such indebtedness could be senior indebtedness. By reason of such subordination, in the event of our insolvency, liquidation or other reorganization, the lenders under our revolving credit facility and other creditors who are holders of our senior indebtedness must be paid in full before the holders of the notes may be paid. Accordingly, there may be insufficient assets remaining after payment of prior claims to pay amounts due on the notes. In addition, under certain circumstances, no payments may be made with respect to the notes if a default exists with respect to our senior indebtedness. See “Description of the Notes — Ranking.”

WESCO International and its subsidiaries’ assets remain subject to a first priority pledge under the revolving credit facility.

       Our obligations under our revolving credit facility are secured by a first priority pledge of and security interest in substantially all of the assets, except for real property, of WESCO International and its subsidiaries. If either we or WESCO International become insolvent or are liquidated, or if payment under our revolving credit facility or any other future secured indebtedness is accelerated, the lenders under our revolving credit facility or such other secured

The guarantee may be unenforceable due to fraudulent conveyance statutes, and, accordingly, you could have no claim against WESCO International.

       Although laws differ among various jurisdictions, a court could, under fraudulent conveyance laws, further subordinate or avoid the guarantees if it found that the guarantees were incurred with actual intent to hinder, delay or defraud creditors, or WESCO International did not receive fair consideration or reasonably equivalent value for the guarantee and that WESCO International was any of the following:

If a court voided the guarantee of WESCO International as the result of a fraudulent conveyance, or held it unenforceable for any other reason, holders of the notes would cease to have a claim against WESCO International based on the guarantee and would solely be creditors of WESCO Distribution.

None of our subsidiaries are guarantors, and your claims will be subordinated to all of the creditors of the non-guarantor subsidiaries.

       Only WESCO International guarantees the notes. In the event of a bankruptcy, liquidation or reorganization of any of the non-guarantor subsidiaries, holders of their indebtedness and their trade creditors will generally be entitled to payment of their claims from the assets of those non-guarantor subsidiaries before any assets of the non-guarantor subsidiaries are made available for distribution to WESCO International or WESCO Distribution. As of June 30, 2006, the notes were structurally junior to approximately $227 million of indebtedness and other liabilities (including trade payables) of these non-guarantor subsidiaries. The non-guarantor subsidiaries generated approximately $564 million of our net sales for the six months ended June 30, 2006 and held approximately $1.3 billion of our consolidated assets at June 30, 2006.

We may be unable to repurchase the notes for cash when required by the holders, including following a change of control.

       Holders of the notes have the right to require us to repurchase the notes on specified dates or upon the occurrence of a change of control prior to maturity as described under “Description of the Notes — Change of Control.” The occurrence of a change of control would also constitute an event of default under our credit facilities, requiring repayment of amounts outstanding thereunder, and the occurrence of a change of control would also enable holders of WESCO International’s convertible senior debentures, if issued, to require WESCO International to repurchase such debentures at a price equal to 100% of the principal amount thereof, plus accrued and unpaid interest (including contingent interest and additional interest, if any). Any of our future debt agreements may contain similar provisions. We may not have sufficient funds to make the required repayments and repurchases at such time or the ability to arrange necessary financing on acceptable terms. In addition, our ability to repurchase the notes in cash may be limited by law or the terms of other agreements relating to our debt outstanding at the time, including our credit facilities, which will limit our ability to purchase the notes for cash in certain circumstances. If we fail to repurchase the notes in cash as required by the indenture, it would constitute an event of default under the indenture governing the notes, which, in turn, would

Some significant restructuring transactions may not constitute a change of control, in which case we would not be obligated to offer to repurchase the notes.

       Upon the occurrence of a change of control, you have the right to require us to offer to repurchase the notes. However, the change of control provisions will not afford protection to holders of the notes in the event of certain transactions. For example, transactions such as leveraged recapitalizations, refinancings, restructurings or acquisitions initiated by us would not constitute a change of control requiring us to repurchase the notes. In the event of any such transaction, the holders would not have the right to require us to repurchase the notes, even though each of these transactions could increase the amount of our indebtedness, or otherwise adversely affect our capital structure or any credit ratings, thereby adversely affecting the holders of the notes.

Provisions of the notes could discourage an acquisition of us by a third party.

       Certain provisions of the notes could make it more difficult or more expensive for a third party to acquire us. Upon the occurrence of certain transactions constituting a change of control, holders of the notes will have the right, at their option, to require us to repurchase all of their notes or any portion of the principal amount of such notes in integral multiples of $1,000.

There is currently no public market for the notes, and an active trading market may not develop for the notes. The failure of a market to develop for the notes could adversely affect the liquidity and value of your notes.

       A market may not develop for the notes, and there can be no assurance as to the liquidity of any market that may develop for the notes. If an active, liquid market does not develop for the notes, the market price and liquidity of the notes may be adversely affected. If any of the notes are traded after their initial issuance, they may trade at a discount from their initial offering price. The liquidity of the trading market, if any, and future trading prices of the notes will depend on many factors, including, among other things, prevailing interest rates, our operating results, financial performance and prospects, the market for similar securities and the overall securities market, and may be adversely affected by unfavorable changes in these factors. Historically, the market for similar debt securities has been subject to disruptions that have caused volatility in prices. It is possible that the market for the notes will be subject to disruptions which may have a negative effect on the holders of the notes, regardless of our operating results, financial performance or prospects.

USE OF PROCEEDS

       We will not receive any proceeds from the resale of notes pursuant to this prospectus. The net proceeds of approximately $145.5 million from the issuance of the original notes were used to finance, in part, our acquisition of Carlton-Bates Company (“Carlton-Bates”) and to redeem a portion of our then outstanding 9¹/8 % Senior Subordinated Notes due 2008 (the “2008 Notes”).

CAPITALIZATION

       The following table sets forth WESCO International’s consolidated cash and cash equivalents and capitalization as of June 30, 2006. This table should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” WESCO International’s consolidated financial statements and related notes and the other information included elsewhere in this prospectus.

SELECTED CONSOLIDATED FINANCIAL DATA

       The table below sets forth certain of WESCO International’s consolidated financial data as of and for each of the periods indicated. The financial data for the years ended December 31, 2005, 2004 and 2003, and as of December 31, 2004 and 2005, is derived from its audited consolidated financial statements which appear elsewhere in this prospectus. The financial data for the years ended December 31, 2002 and 2001, and as of December 31, 2001, 2002 and 2003, is derived from WESCO International’s audited consolidated financial statements which do not appear in this prospectus. The financial data for the six-month periods ended June 30, 2005 and 2006, and as of June 30, 2005 and 2006, is derived from WESCO International’s unaudited condensed consolidated financial statements, which are included elsewhere in this prospectus. In WESCO International’s opinion, such unaudited condensed consolidated financial statements include all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of the financial data for such periods. The results for the six months ended June 30, 2006 are not necessarily indicative of the results to be achieved for the year ending December 31, 2006 or for any other future period.

       The data below should be read in conjunction with “Capitalization,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and WESCO International’s consolidated financial statements, including the notes thereto, which appear elsewhere in this prospectus.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

       The following discussion should be read in conjunction with the audited consolidated financial statements of WESCO International and the related notes thereto included elsewhere in this prospectus. For purposes of this discussion, the terms “we,” “us,” “our,” the “Company” and “WESCO” refer to WESCO International and its consolidated subsidiaries. The principal asset of WESCO International is all of the outstanding capital stock of WESCO Distribution.

Company Overview

       We are a full-line distributor of electrical supplies and equipment and a provider of integrated supply procurement services. WESCO has more than 370 full service branches and seven distribution centers located in the United States, Canada, Mexico, Puerto Rico, Guam, the United Kingdom, Nigeria, United Arab Emirates and Singapore. We serve over 100,000 customers worldwide, offering over 1,000,000 products from over 24,000 suppliers. Our diverse customer base includes a wide variety of industrial companies; contractors for industrial, commercial and residential projects; utility companies, and commercial, institutional and governmental customers. Approximately 87% of our net sales are generated from operations in the U.S., 11% from Canada and the remainder from other countries.

       Sales increases attributed to growth in our served markets and from the two acquisitions completed in 2005, along with positive impact from our productivity initiatives, contributed to improved financial results for the first six months of 2006. Sales increased $548.6 million, or 26.7%, over the same period last year. Gross margin was 20.1% and 18.5% for the first six months of 2006 and 2005, respectively. During the first six months of 2006, sales from our acquisitions, both of which were completed in the third quarter of 2005, were $214 million in the aggregate and accounted for 10.4% of the improved sales versus 2005. Favorable exchange rates accounted for approximately 1% of the higher revenues. The remainder of the 2006 sales increase was the result of a combination of market and share growth, higher commodity prices, hurricane rebuilding activity, and an additional workday. Operating income improved by $84.2 million, or 96%, with $24.8 million of the increase attributed to our 2005 acquisitions compared with last year’s similar period. Operating income improvement was due mainly to sales growth, gross margin expansion, acquisitions and cost containment. The net income for the six months ending June 30, 2006 and 2005 was $99.6 million and $38.8 million, respectively.

Cash Flow

       We generated $59.6 million in operating cash flow for the first six months of 2006. Included in this amount was a $17 million reduction in the amount outstanding under our Receivables Facility, whereby we sell, on a continuous basis, an undivided interest in all domestic accounts receivable to WESCO Receivables Corp., a wholly owned, special purpose entity. Investing activities in the first six months of 2006 included $8.7 million in capital expenditures and acquisition payments of $10.9 million. Financing activities during the first six months of 2006 consisted of borrowings of $215.9 million related to our revolving credit facility and repayments of $244.9 million related to our revolving credit facility, $20 million related to the Bruckner Note Payable and $0.6 million related our mortgage financing facility.

Financing Availability

       As of June 30, 2006, we had approximately $275 million in available borrowing capacity under our revolving credit facility, of which $225 million is the U.S sub-facility borrowing limit and $50 million is the Canadian sub-facility borrowing limit.

       We believe that acquisitions and improvements in operations and our capital structure made in 2005 have positioned us well for 2006. We continue to see macroeconomic data that reflects good activity levels in our major end markets. We continue to focus on selling and marketing initiatives to increase market share and pricing and procurement initiatives to achieve margin expansion and cost containment as we drive towards continued improvement in our operating performance for the second half of 2006.

Critical Accounting Policies and Estimates

       Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to supplier programs, bad debts, inventories, insurance costs, goodwill, income taxes, contingencies and litigation. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. If actual market conditions are less favorable than those projected by management, additional adjustments to reserve items may be required. We believe the following critical accounting policies affect our judgments and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition

       Revenues are recognized for product sales when title, ownership and risk of loss pass to the customer, or for services when the service is rendered or evidence of a customer arrangement exists. In the case of stock sales and special orders, a sale occurs at the time of shipment from our distribution point, as the terms of WESCO’s sales are FOB shipping point. In cases where we process customer orders but ship directly from our suppliers, revenue is recognized once product is shipped and title has passed. For some of our customers, we provide services such as inventory management or other specific support. Revenues are recognized upon evidence of fulfillment of the agreed upon services. In all cases, revenue is recognized once the sales price to our customer is fixed or is determinable and WESCO has reasonable assurance as to the collectibility in accordance with Staff Accounting Bulletin No. 104.

Gross Profit

       Our calculation of gross profit is net sales less cost of goods sold. Cost of goods sold includes our cost of the products sold and excludes cost for warehousing, selling, general and administrative expenses and depreciation and amortization, which are reported separately in the statement of income.

Allowance for Doubtful Accounts

       We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. We have a systematic procedure using estimates based on historical data and reasonable assumptions of collectibles made at the local branch level and on a consolidated corporate basis to calculate the allowance for doubtful accounts.

       We write down our inventory for estimated obsolescence or unmarketable inventory equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. A systematic procedure is used to determine excess and obsolete inventory reflecting historical data and reasonable assumptions for the percentage of excess and obsolete inventory on a consolidated basis.

Supplier Volume Rebates

       We receive rebates from certain suppliers based on contractual arrangements with them. Since there is a lag between actual purchases and the rebates received from the suppliers, we must estimate and accrue the approximate amount of rebates available at a specific date. We record the amounts as other accounts receivable on the balance sheet. The corresponding rebate income is recorded as a reduction of cost of goods sold. The appropriate level of such income is derived from the level of actual purchases made by WESCO from suppliers, in accordance with the provisions of Emerging Issues Task Force Issue No. 02-16, Accounting by a Reseller for Cash Consideration Received from a Vendor.

Goodwill

       As described in the notes to the consolidated financial statements, we test goodwill for impairment annually or more frequently when events or circumstances occur indicating goodwill might be impaired. This process involves estimating fair value using discounted cash flow analyses. Considerable management judgment is necessary to estimate discounted future cash flows. Assumptions used for these estimated cash flows were based on a combination of historical results and current internal forecasts. Two primary assumptions were an average long-term revenue growth ranging from 3% to 13% depending on the end market served and a discount rate of 8%. We cannot predict certain events that could adversely affect the reported value of goodwill, which totaled $550.8 million at June 30, 2006, $542.2 million at December 31, 2005 and $401.6 million at December 31, 2004.

Intangible Assets

       We account for certain economic benefits purchased as a result of our acquisitions, including customer relations, distribution agreements and trademarks, as intangible assets and amortize them over a useful life determined by the expected cash flows produced by such intangibles and their respective tax benefits. Useful lives vary between five and 19 years, depending on the specific intangible asset.

Insurance Programs

       We use commercial insurance for auto, workers’ compensation, casualty and health claims as a risk reduction strategy to minimize catastrophic losses. Our strategy involves large deductibles where we must pay all costs up to the deductible amount. We estimate our reserve based on historical incident rates and costs.

Income Taxes

       We record our deferred tax assets at amounts that are expected to be realized. We evaluate future taxable income and potential tax planning strategies in assessing the potential need for a valuation allowance. Should we determine that we would not be able to realize all or part of our deferred tax assets in the future, an adjustment to the deferred tax asset would be charged to income in the period such determination was made. We review tax issues and positions taken on tax returns and determine the need and amount of contingency reserves necessary to cover any probable audit adjustments.

       Our Receivables Facility, through an SPE, sells, without recourse, to a third-party conduit all the eligible receivables while maintaining a subordinated interest, in the form of over-collateralization, in a portion of the receivables.

       We account for the Receivables Facility in accordance with SFAS No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities. At the time the receivables are sold, the balances are removed from our balance sheet. The Receivables Facility represents “off-balance sheet financing,” since the conduit’s ownership interest in the accounts receivable of the SPE results in the removal of accounts receivable from our consolidated balance sheets, rather than resulting in the addition of a liability to the conduit.

       We believe that the terms of the agreements governing this Receivables Facility not only provide a very favorable borrowing rate but also qualify our trade receivable sales transactions for “sale treatment” under generally accepted accounting principles, which requires us to remove the accounts receivable from our consolidated balance sheets. Absent this “sale treatment,” our consolidated balance sheet would reflect additional accounts receivable and debt. Our consolidated statements of income would not be impacted, except that other expenses would be classified as interest expense.

Results of Operations

       The following table sets forth the percentage relationship to net sales of certain items in our condensed consolidated statements of income for the periods presented:

       Sales increases attributed to growth in our markets served and from the two acquisitions completed in 2005, along with positive impact from gross margin improvements and our cost improvement initiatives, contributed to improved financial results for the second quarter of 2006. Net sales in the second quarter of 2006 totaled $1,336 million versus $1,062.1 million in the comparable period for 2005, an increase of $274 million or 25.8% over the same period last year. Second quarter 2006 sales from our acquisitions, both of which were completed in the third quarter of 2005, were $107.4 million. Favorable exchange rates accounted for approximately 1% of the higher sales. The remainder of the 2006 sales increase was the result of a combination of market and share growth and higher commodity prices.

       Gross profit for the second quarter of 2006 was $270.6 million versus $194.6 million for the comparable period in 2005, and gross margin percentage of net sales was 20.3% in 2006 versus 18.3% in 2005. The increase was attributable primarily to the combination of continued margin

       Selling, general and administrative (“SG&A”) expenses in the second quarter of 2006 totaled $169.6 million versus $142 million in last year’s comparable quarter. As a percentage of net sales, SG&A expenses were 12.7% in the second quarter of 2006 compared to 13.4% in the second quarter in 2005, reflecting the positive impact of cost containment initiatives and the leverage of higher sales volume.

       SG&A payroll expenses for the second quarter of 2006 of $120.1 million increased by $25.6 million compared to the same quarter in 2005, of which $11.6 million resulted from the 2005 acquisitions. Of the remaining $14 million increase in payroll expenses, $10 million was from increased salaries and variable commissions and incentive compensation costs resulting from increased sales and related gross margins, $1.1 million was from increased employee benefit costs, and $1 million was from increased stock option expense.

       The remaining SG&A expenses for the second quarter of 2006 of $49.5 million increased by approximately $1.9 million compared to same quarter in 2005, primarily from increases of $5.2 million resulting from the 2005 acquisitions. This increase was offset by a reduction in bad debts primarily due to a $2 million reversal of the $4 million in bad debt expense incurred in the first quarter related to the write-down of accounts receivables from a major customer which filed for bankruptcy.

       Depreciation and amortization for the second quarter of 2006 was $6.3 million versus $3.7 million in last year’s comparable quarter. Of the $2.6 million increase, $2.5 million is related to the two acquisitions in 2005, of which $1.9 million is due to the amortization expense of the intangible assets acquired and $0.6 million is due to the depreciation of the fixed assets acquired.

       Interest expense totaled $5.6 million for the second quarter of 2006 versus $6.8 million in last year’s comparable quarter, a decrease of 18%. This decrease was due primarily to lower interest on debt in 2006 resulting from the redemption of higher interest rate notes, which were replaced with lower interest rates on both the 2017 Notes and the Debentures.

       Other expense during the second quarter of 2006 increased to $6.3 million versus $3 million in 2005, reflecting costs associated with the Receivables Facility resulting from an increase in the average of the accounts receivable sold for the second quarter of 2006 to $389.7 million versus $317.4 million in last year’s comparable quarter and higher discount rates.

       Income tax expense totaled $27.7 million in the second quarter of 2006 and the effective tax rate was 33.4% compared to 29.8% in the same quarter in 2005. The current quarter’s effective tax rate differed from the statutory rate primarily as a result of the domestic tax benefit from foreign operations, and the domestic production activity deduction. The increase in the effective tax rate in 2006 as compared to 2005 is primarily due to the benefit in 2005 from research and development credits.

       For the second quarter of 2006, net income increased by $27.7 million to $55.2 million, or $1.05 per diluted share, compared with $27.4 million and $0.56 per diluted share for the second quarter of 2005. The increase in net income was primarily attributable to increased sales, gross margin expansion, decreases in the SG&A expenses as a percent of net sales, decrease in interest expense and increases in depreciation and amortization and other expense and a 3.6% point increase in the effective tax rate.

       Sales increases attributed to growth in our markets served and from the two acquisitions completed in 2005, along with positive impact from gross margin improvements and our cost improvement initiatives, contributed to improved financial results for the first six months of 2006. Net sales in the first six months of 2006 totaled $2,601.5 million versus $2,052.9 million in the comparable period for 2005, an increase of $548.6 million, or 26.7%, over the same period last year. First six months 2006 sales from our acquisitions, both of which were completed in the third quarter of 2005, were $214 million in the aggregate. Favorable exchange rates accounted for approximately 1% of the higher sales. The remainder of the 2006 sales increase was the result of a combination of market and share growth, higher commodity prices, hurricane rebuilding activity, and an additional workday.

       Gross profit for the first six months of 2006 was $523.7 million versus $379.8 million for the comparable period in 2005, and gross margin percentage of net sales was 20.1% in 2006 versus 18.5% in 2005. The increase was attributable primarily to the combination of continued margin improvement initiatives and the higher margins from the acquisitions completed in the second half of 2005.

       SG&A expenses in the first six months of 2006 totaled $339.4 million versus $284.7 million in last year’s comparable period. As a percentage of net sales, SG&A expenses were 13% in the first six months of 2006 compared to 13.9% in the second six months of 2005, reflecting the positive impact of cost containment initiatives and the leverage of higher sales volume.

       SG&A payroll expenses for the first six months of 2006 of $239 million increased by $46.8 million compared to the same period in 2005, of which $22.5 million resulted from the 2005 acquisitions. Of the remaining $24.3 million increase in payroll expenses, $17.3 million was from increased salaries and variable commissions and incentive compensation costs resulting from increased sales and related gross margins, $2.0 million was from increased employee benefit costs, and $1.9 million was from increased stock option expense ($.1 million attributable to the implementation of SFAS 123R).

       The remaining SG&A expenses for the first six months of 2006 of $100.4 million increased by approximately $7.9 million compared to same period in 2005, primarily from increases of $10.8 million resulting from the 2005 acquisitions and $2 million in bad debt expense related to the write-down of accounts receivables from a major customer which filed for bankruptcy. This

       Depreciation and amortization for first six months of 2006 was $12.6 million versus $7.6 million in last year’s comparable period. Of the $5 million increase, $4.9 million is related to the two acquisitions in 2005, of which $3.7 million is due to the amortization expense of the intangible assets acquired and $1.2 million is due to the depreciation of the fixed assets acquired.

       Interest expense totaled $12 million for the first six months of 2006 versus $16 million in last year’s comparable period, a decrease of 25%. This decrease was due primarily to lower interest on debt in 2006 resulting from the redemption of higher interest rate notes, which were replaced with lower interest rates on both the 2017 Notes and the Debentures.

       On March 1, 2005, we redeemed $123.8 million in aggregate principal amount of our 2008 Notes and incurred a pretax loss of $10.1 million resulting from the payment of the call premium and the write-off of the unamortized original issue discount and debt issue costs.

       Other expense during the first six months of 2006 increased to $11.3 million versus $5 million in 2005, reflecting costs associated with the Receivables Facility resulting from an increase in the average of the accounts receivable sold for the first six months of 2006 to $386.2 million versus $289.2 million in last year’s comparable period and higher discount rates.

       Income tax expense totaled $48.7 million in the first six months of 2006, and the effective tax rate was 32.8% compared to 31.3% in the same period in 2005. The current period’s effective tax rate differed from the statutory rate primarily as a result of the domestic tax benefit from foreign operations, and the domestic production activity deduction. The increase in the effective tax rate in 2006 as compared to 2005 is primarily due to the benefit in 2005 from research and development credits.

       For the first six months of 2006, net income increased by $60.8 million to $99.6 million, or $1.91 per diluted share, compared with $38.8 million and $0.79 per diluted share for the first six months of 2005. The increase in net income was primarily attributable to increased sales, gross margin expansion, decreases in the SG&A expenses as a percent of net sales, decrease in interest expense, the 2005 loss on debt extinguishment and increases in depreciation and amortization and other expense and a 1.5% point increase in the effective tax rate.

2005 Compared to 2004

       Net Sales. Sales in 2005 increased 18.2% to $4,421 million, compared with $3,741 million in 2004, primarily as a result of strong growth in our markets served, acquisitions and market share gains. Sales from our 2005 acquisitions, both of which were purchased in the third quarter, were $104.4 million or approximately 2.8% over 2004 sales. Sales in 2005 also benefited by approximately 4.0% over 2004 from price increases which kept pace with rising cost of sales, approximately 0.9% from favorable currency exchange rates, and the remaining 10.5% from higher sales volume, of which approximately 1.0% was hurricane related. Sales volume in 2005 grew faster than that of our end markets served.

       Gross Profit. Gross profit increased 18.1% in 2005 to $841 million, compared with $712 million in 2004, driven primarily by higher sales volume including acquisitions completed in 2005. Gross margin percentage was 19.0% in both years. Price increases in 2005 matched increases in cost of sales. Gross margin impact from sales mix was slightly less favorable in 2005 compared with 2004. However, acquisitions contributed positively to gross margin in 2005, resulting in equivalent gross margin percentages for both years.

       Depreciation and Amortization. Depreciation and amortization increased $0.5 million to $18.6 million in 2005, compared with $18.1 million in 2004. Depreciation and amortization related to acquisitions completed in 2005 was $2.7 million. Depreciation and amortization from operations excluding acquisition declined by $2.2 million from 2004 amounts as certain assets became fully depreciated.

       Income from Operations. Income from operations increased by $59.8 million, or 40%, to $209.3 million in 2005, compared with $149.4 million in 2004. The increase in operating income resulted from higher sales, an increase in gross profit and control over SG&A expenses.

       Interest Expense. Interest expense totaled $30.2 million in 2005, compared with $40.8 million in 2004. The decrease was due primarily to redemptions of the 2008 Notes, which occurred in 2005 and to comparatively lower interest rates on the original notes and our Debentures.

       Loss on Debt Extinguishment. Loss on debt extinguishment was $14.9 million in 2005 resulting from charges associated with the redemption of $324 million in aggregate principal amount of 2008 Notes. Loss on debt extinguishment in 2004 was $2.6 million, reflecting redemptions of $55.0 million in aggregate principal amount of 2008 Notes.

       Other Expenses. Other expenses increased in 2005 to $13.3 million, compared to $6.6 million in 2004, as a result of higher interest rates and increased borrowing under our Receivables Facility in 2005.

       Income Taxes. Our effective income tax rate decreased to 31.4% in 2005, compared with 34.7% in 2004, as a result of tax planning initiatives, which included U.S. tax benefits from foreign operations and U.S. tax credits.

       Net Income. Net income and diluted earnings per share on a consolidated basis totaled $103.5 million and $2.10 per share, respectively, in 2005, compared with $64.9 million and $1.47 per share, respectively, in 2004.

2004 Compared to 2003

       Net Sales. Net sales for 2004 increased by approximately $454 million, or 13.8%, compared with the prior year. Approximately 11% of the increase in sales was attributable to strong demand from our end markets served. The remaining increase was split between approximately 2% from improved pricing which compensated for rising costs of commodity products and approximately 1% from the strength of the Canadian dollar.

       Selling, General and Administrative Expenses. SG&A expenses include costs associated with personnel, shipping and handling, travel and entertainment, advertising, utilities and bad debts. SG&A expenses increased by $43.1 million, or 8.6%, to $544.5 million. Total payroll expense increased approximately $40.9 million over last year principally from increased variable incentive compensation costs of $19.7 million, increased healthcare and benefits costs of $10.1 million, and expense related to equity awards, which increased by $2.3 million compared to 2003. Bad debt expense decreased to $5.8 million for 2004, compared to $10.2 million for 2003, primarily due to efficient collection efforts and an improved economic environment. Shipping and handling expense included in SG&A was $36.6 million in 2004 compared with $36.2 million in 2003. As a percentage of net sales, SG&A expenses decreased to 14.6%, compared with 15.3% in 2003, reflecting LEAN initiatives and the leverage of higher sales volume.

       Depreciation and Amortization. Depreciation and amortization decreased $4.4 million to $18.1 million in 2004 versus $22.6 million in 2003. Amortization decreased by $1.6 million due to less amortization associated with a non-compete agreement that was fully amortized in 2003. Amortization of capitalized software decreased $1.1 million as assets became fully amortized. Depreciation decreased $1.1 million principally due to less depreciation expense on computer hardware as the applicable assets became fully depreciated.

       Income from Operations. Income from operations increased $63.4 million to $149.4 million in 2004, compared with $86.0 million in 2003. The increase in operating income was principally attributable to the increase in gross profit partially offset by the increase in SG&A expenses.

       Interest and Other Expenses. Interest expense totaled $40.8 million for 2004, a decrease of $1.5 million from 2003. The decline was primarily due to a lower average amount of indebtedness outstanding during the current period as compared to 2003, as we continued to improve our liquidity by reducing debt. Loss on debt extinguishments of $2.6 million related to losses on the repurchase of 2008 Notes versus $0.2 million last year. Other expenses, which reflects costs associated with the accounts receivable securitization, totaled $6.6 million and $4.5 million in 2004 and 2003, respectively, as a result of an increase in the average receivable balance and higher interest rates.

       Income Taxes. Income tax expense totaled $34.6 million in 2004, an increase of $25.5 million from 2003. The effective tax rates for 2004 and 2003 were 34.7% and 23.2%, respectively. In 2004, we recapitalized our Canadian operations to reflect the proportionate debt structure of the Canadian and U.S. operations and to improve efficiency in cash flow movement of funds for business purposes. The 2003 tax provision included a benefit of $2.6 million as a result of the favorable conclusion of an IRS examination. Additionally, foreign tax credits contributed to the reduction in the effective rate during 2003.

       Net Income. Net income and diluted earnings per share totaled $64.9 million and $1.47 per share, respectively, in 2004, compared with $30.0 million and $0.65 per share, respectively, in 2003.

Liquidity and Capital Resources

       Total assets at June 30, 2006 and December 31, 2005 were $1.8 billion and $1.7 billion, respectively. During the first six months of 2006, total liabilities decreased by $23 million to $1.1 billion. This decrease was due primarily to a reduction in accrued payroll and benefit costs of $14.1 million primarily from the payment in 2006 of the 2005 management incentive

       Our liquidity needs arise from working capital requirements, capital expenditures, acquisitions and debt service obligations. In addition, an acquisition agreement to which we are a party contains contingent consideration for the final acquisition payment which management has estimated will be $1.1 million and paid in 2007 and is included in the current portion of deferred acquisition payable of $4.6 million at June 30, 2006.

       We finance our operating and investing needs, as follows:

       The revolving credit facility matures in June 2010 and provides for an aggregate borrowing limit of up to $275 million. During the six months ended June 30, 2006, borrowings were $215.9 million and repayments were $244.9 million, with no outstanding balance at June 30, 2006, and, consequently, we were not subject to any covenants in the agreement governing the revolving credit facility.

       In February 2003, we finalized a $51 million mortgage financing facility, $47.6 million of which was outstanding as of June 30, 2006. Borrowings under the mortgage financing are collateralized by 75 domestic properties and are subject to a 22-year amortization schedule with a balloon payment due at the end of the 10-year term. Interest rates on borrowings under this facility are fixed at 6.5%.

       Pursuant to the Bruckner purchase agreement and in accordance with the terms of a promissory note, the remaining payment of $20 million was paid in June 2006.

       At June 30, 2006, $150 million in aggregate principal amount of the 2017 Notes were outstanding. The 2017 Notes were issued by WESCO Distribution under an indenture dated as of September 27, 2005 with J.P. Morgan Trust Company, National Association, as trustee, and are unconditionally guaranteed on an unsecured basis by WESCO International. The 2017 Notes accrue interest at the rate of 7.50% per annum and are payable in cash semi-annually in arrears on each April 15 and October 15, commencing April 15, 2006.

       At June 30, 2006, $150 million in aggregate principle amount of the Debentures was outstanding. The Debentures were issued by WESCO International under an indenture dated as of September 27, 2005 with J.P. Morgan Trust Company, National Association, as Trustee, and are unconditionally guaranteed on an unsecured senior subordinated basis by WESCO Distribution. The Debentures accrue interest at the rate of 2.625% per annum and are payable in cash semi-annually in arrears on each April 15 and October 15, commencing April 15, 2006. Beginning with the six-month interest period commencing October 15, 2010, we also will pay contingent interest in cash during any six-month interest period in which the trading price of the Debentures for each of the five trading days ending on the second trading day immediately preceding the first day of the applicable six-month interest period equals or exceeds 120% of the principal amount of the Debentures. During any interest period when contingent interest shall be payable, the contingent interest payable per $1,000 principal amount of Debentures will equal

       The Debentures are convertible into cash and, in certain circumstances, shares of WESCO International, Inc.’s common stock, $0.01 par value, at any time on or after October 15, 2023, or prior to October 15, 2023 in certain circumstances. The Convertible Debentures will be convertible based on an initial conversion rate of 23.8872 shares of common stock per $1,000 principal amount of the Debentures (equivalent to an initial conversion price of approximately $41.86 per share). The conversion rate and the conversion price may be adjusted under certain circumstances.

       At any time on or after October 15, 2010, we may redeem all or a part of the Debentures at a redemption price equal to 100% of the principal amount of the Debentures plus accrued and unpaid interest (including contingent interest and additional interest, if any) to, but not including, the redemption date. Holders of Debentures may require us to repurchase all or a portion of their Debentures on October 15, 2010, October 15, 2015 and October 15, 2020 at a cash repurchase price equal to 100% of the principal amount of the Debentures, plus accrued and unpaid interest (including contingent interest and additional interest, if any) to, but not including, the repurchase date. If we undergo certain fundamental changes prior to maturity, holders of Debentures will have the right, at their option, to require us to repurchase for cash some or all of their Debentures at a repurchase price equal to 100% of the principal amount of the Debentures being repurchased, plus accrued and unpaid interest (including contingent interest and additional interest, if any) to, but not including, the repurchase date.

       Operating Activities-2006. Cash provided by operating activities for the first six months of 2006 totaled $59.6 million primarily as the result of net income of $99.6 million, adjusted for, among other items, depreciation and amortization of $12.6 million of which $4.9 million is related to two acquisitions in the second half of 2005, stock-based compensation of $5.1 million and the reclassification of $24.2 million related to the excess tax benefit from stock-based compensation expense. Cash provided by operating activities in the first six months of 2006 included $24.9 million from prepaid expenses and other current assets including $2.5 million from foreign income taxes receivable and $35.4 million in accounts payable related to increased sales and inventory. Additionally, $3.0 million was provided from other current and noncurrent liabilities of which $1.3 million is related to a decrease in accrued interest payable primarily from the payment in April 2006 related to the 2017 Notes and Debentures and the payment in June 2005 related to the Bruckner Note Payable and $3.0 million increase in accrued acquisition related expenses related to the Carlton-Bates acquisition. Cash used by operating activities in the first six months of 2006 included: $17.0 million reduction in the receivables facility; $35.8 million increase in trade and other receivables resulting from higher sales volume; $32.8 million increase in inventories to accommodate increased sales demand and $14.1 million reduction in accrued payroll and benefit costs primarily from $27.4 million of incentive compensation payments related to 2005 which was offset by increased accrued payroll and benefits costs primarily related to the $16.2 million accrual of the 2006 incentive compensation.

       Operating Activities-2005. Cash provided by operating activities during the first six months of 2005 totaled $135.2 million as the result of net income of $38.8 million, adjusted for, among other items, $1.9 million related to the loss on debt extinguishment, $7.6 million of depreciation and amortization and $3.1 million of stock-based compensation. Cash provided by operating activities in the first six months of 2005 included: $122.0 million related to the receivables facility;

       Investing Activities. Net cash used in investing activities for the first six months of 2006 and 2005 was $20.1 million and $8.9 million, respectively, of which capital expenditures were $8.7 million and $7.9 million, respectively, and expenditures of $10.9 million in 2006 and $1 million in 2005 were made pursuant to the terms of an acquisition purchase agreement.

       Financing Activities. Net cash used by financing activities for the six months of 2006 and 2005 was $23.7 million and $145.6 million, respectively. During the first six months of 2006, borrowings and repayments of debt included borrowings of $215.9 million related to our revolving credit facility and repayments of $244.9 million related to our revolving credit facility, $20 million related to the Bruckner Note Payable and $0.6 million related to our mortgage financing facility. During the first six months of 2005, the Company redeemed $123.8 million in aggregate principal amount of 2008 Notes. Proceeds and repayments from long-term debt, inclusive of the redemption of the senior subordinated notes during the first six months of 2005, were $147.4 million and $297.3 million, respectively. During the first six months of 2006 and 2005, the proceeds from the exercise of stock-based compensation arrangements were $6.6 million and $5.3 million, respectively. During the first six months of 2006, expenditures of $0.6 million were made in conjunction with the issuance of the 2017 Notes and the Debentures 7.5%. During the first six months of 2005, expenditures of $0.9 million were made in conjunction with the amendments to the revolving credit facility and the receivables facility.

Contractual Cash Obligations and Other Commercial Commitments

       The following summarizes our contractual obligations, including interest, at December 31, 2005 and the effect such obligations are expected to have on liquidity and cash flow in future periods. There were not any material changes in our contractual obligations and other commercial commitments in the fiscal quarter ended June 30, 2006.

       Purchase orders for inventory requirements and service contracts are not included in the table above. Generally, our purchase orders and contracts contain clauses allowing for cancellation. We do not have significant agreements to purchase material or goods that would specify minimum order quantities.

       Management believes that cash generated from operations, together with amounts available under our revolving credit facility and the Receivables Facility, will be sufficient to meet our working capital, capital expenditures estimated to be $16.0 million in 2006 and other cash

Off-Balance Sheet Arrangements

       We maintain a Receivables Facility, that had a total purchase commitment of $400 million as of June 30, 2006. The Receivables Facility has a term of three years and is subject to renewal in May 2008. Under the Receivables Facility, we sell, on a continuous basis, an undivided interest in all domestic accounts receivable to WESCO Receivables Corporation, a wholly owned SPE. The SPE sells, without recourse, to a third-party conduit all the eligible receivables while maintaining a subordinated interest, in the form of over-collateralization, in a portion of the receivables. We have agreed to continue servicing the sold receivables for the financial institution at market rates; accordingly, no servicing asset or liability has been recorded. As of June 30, 2006, $380 million in funding was outstanding under the Receivables Facility.

Inflation

       The rate of inflation affects different commodities and the cost of products purchased and ultimately the pricing of our different products and product classes. On an overall basis, our pricing related to inflation comprised an estimated $65 to $80 million of our sales growth for the three months ended June 30, 2006 and an estimated $125 to $155 million of our sales growth for the six months ended June 30, 2006.

Seasonality

       Our operating results are not significantly affected by seasonal factors. Sales during the first quarter are generally less than 2% below the sales of the remaining three quarters due to a reduced level of activity during the winter months of January and February. Sales increase beginning in March with slight fluctuations per month through December.

Impact of Recently Issued Accounting Standards

       In May 2005, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 154, Accounting Changes and Error Corrections, which changes the requirements for the accounting and reporting of a change in accounting principle. SFAS No. 154 applies to all voluntary changes in accounting principle as well as to changes required by an accounting pronouncement that does not include specific transition provisions. SFAS No. 154 eliminates the requirement to include the cumulative effect of changes in accounting principle in the income statement and instead requires that changes in accounting principle be retroactively applied. A change in accounting estimate continues to be accounted for in the period of change and future periods if necessary. A correction of an error continues to be reported by restating prior period financial statements. SFAS No. 154 is effective for us for accounting changes and correction of errors made on or after January 1, 2006. The adoption of SFAS No. 154 is not expected to have a material impact on our financial position or results of operations.

       In March 2006, the FASB issued SFAS No. 156, Accounting for Servicing of Financial Assets.-.an amendment of FASB Statement No. 140 (SFAS 156) which amends FASB Statement No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities, with respect to the accounting for separately recognized servicing assets and servicing liabilities. This statement clarifies when servicing rights should be separately accounted for, requires companies to account for separately recognized servicing rights initially at fair value, and gives companies the option of subsequently accounting for those servicing rights at either fair value or under the amortization method. SFAS 156 is effective for fiscal years beginning after September 15, 2006. Consistent with its requirements, WESCO will adopt SFAS 156 on January 1, 2007. WESCO is currently evaluating the effect that implementation of SFAS 156 will have on its financial position, results of operations and cash flows.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS

Foreign Currency Risks

       Approximately 90% of our sales are denominated in U.S. dollars and are primarily from customers in the United States. As a result, currency fluctuations are currently not material to our operating results. We do have foreign subsidiaries located in North America, Europe and Asia and may establish additional foreign subsidiaries in the future. Accordingly, we may derive a more significant portion of our sales from international operations, and a portion of these sales may be denominated in foreign currencies. As a result, our future operating results could become subject to fluctuations in the exchange rates of those currencies in relation to the U.S. dollar. Furthermore, to the extent that we engage in international sales denominated in U.S. dollars, an increase in the value of the U.S. dollar relative to foreign currencies could make our products less competitive in international markets. We have monitored and will continue to monitor our exposure to currency fluctuations.

Interest Rate Risk

       At various times, we have refinanced our fixed rate debt to better leverage the impact of interest rate fluctuations. The majority of our debt portfolio is comprised of fixed rate debt in order to mitigate the impact of fluctuations in interest rates. Our variable rate borrowings at December 31, 2005 and 2004 of $29.0 million and $49.4 million, respectively, represented approximately 7% and 12% of total indebtedness at December 31, 2005 and 2004, respectively.

       Fixed Rate Borrowings: In 2005 we reduced our borrowing rate on a major portion of our fixed-rate debt, redeeming $323.5 million in aggregate, principal outstanding on our 2008 Notes at 9.125%, and issuing $150 million of our original notes at 7.50% and $150 million of our Debentures at 2.625%. As these borrowings were issued at fixed rates, interest expense would not be impacted by interest rate fluctuations, although market value would be. Historically, we have used interest swap agreements to mitigate the risk of changes in fair value due to interest rate fluctuations. At December 31, 2005, interest rates were within 100 basis points of the coupon rate of the original notes and the Debentures. Fair value exceeded carrying value of these debt instruments (see Note 8 to WESCO International’s audited consolidated financial statements appearing elsewhere in this prospectus). Interest expense on our other fixed rate debt also was not impacted due to changes in market interest rates, and fair value approximated carrying value for this debt as well.

       Floating Rate Borrowings: We borrow under our revolving credit facility for general corporate purposes, including working capital requirements and capital expenditures. During 2005, our average daily borrowing under the facility was $11.9 million. Borrowings under our facility bear interest at the applicable LIBOR or base rate, as defined, and therefore we are subject to fluctuations in interest rates.

BUSINESS

The Company

       With sales of $4.4 billion in 2005 and $2.6 billion in the six months ended June 30, 2006, we are a leading North American provider of electrical construction products and electrical and industrial maintenance, repair and operating supplies, commonly referred to as “MRO.” We believe we are the largest distributor in terms of sales in the estimated $74 billion* U.S. electrical wholesale distribution industry based upon published industry sources and our assessment of peer company 2005 sales. We believe we are also the largest provider of integrated supply services for MRO goods and services in the United States.

       Our distribution capability combined with integrated supply solutions and outsourcing services are designed to fulfill a customer’s MRO procurement needs. We have more than 370 full service branches and seven distribution centers located in the United States, Canada, Mexico, Puerto Rico, Guam, the United Kingdom, Nigeria, United Arab Emirates and Singapore. We serve approximately 100,000 customers worldwide, offering more than 1,000,000 products from more than 24,000 suppliers utilizing a highly automated, proprietary electronic procurement and inventory replenishment system. Our diverse customer base includes a wide variety of industrial companies; contractors for industrial, commercial and residential projects; utility companies; and commercial, institutional and governmental customers. Our top ten customers accounted for approximately 14% of our sales in 2005. Our leading market positions, experienced workforce, extensive geographic reach, broad product and service offerings and acquisition program have enabled us to grow our market position.

Industry Overview

       The electrical distribution industry serves customers in a number of markets including the industrial, electrical contractors, utility, government and institutional markets. Electrical distributors provide logistical and technical services for customers along with a wide range of products typically required for the construction and maintenance of electrical supply networks, including wire, lighting, distribution and control equipment and a wide variety of electrical supplies. Many customers demand that distributors provide a broader and more complex package of services as they seek to outsource non-core functions and achieve cost savings in purchasing, inventory and supply chain management.

       Electrical Distribution. According to Electrical Wholesaling Magazine, the U.S. electrical wholesale distribution industry had forecasted sales of approximately $74 billion in 2005. According to published sources*, our industry has grown at an approximate 5% compounded annual rate over the past 20 years. This expansion has been driven by general economic growth, increased price levels for key commodities, increased use of electrical products in businesses and industries, new products and technologies and customers who are seeking to more efficiently purchase a broad range of products and services from a single point of contact, thereby eliminating the costs and expenses of purchasing directly from manufacturers or multiple sources. The U.S. electrical distribution industry is highly fragmented. In 2004, the latest year for which market share data is available, the four national distributors, including us, accounted for approximately 18% of estimated total industry sales.

       Integrated Supply. The market for integrated supply services has grown rapidly in recent years. Growth has been driven primarily by the desire of large industrial companies to reduce operating expenses by implementing comprehensive third-party programs, which outsource cost-

Electrical Wholesaling’s 2004 estimated industry sales of $83 billion had aggregated $67 billion wholesale and $16 billion retail sales.

Business Strategy

       We believe we are the leading provider of electrical products and MRO supplies and services to companies in North America and selected international markets. Our goal is to grow earnings at a faster rate than sales by continuing to focus on margin enhancement and continuous productivity improvement. Our growth strategy utilizes our existing strengths and focuses on developing new initiatives and programs to position us to grow at a faster rate than the industry.

       Enhance Our Leadership Position in Electrical Distribution. We will continue to capitalize on our extensive market presence and brand equity in the WESCO name to grow our market position in electrical distribution. As a result of our geographical coverage, effective information systems and value-added products and services, we believe we have become a leader in serving several important and growing markets including:

       We are focusing our sales and marketing efforts in three primary areas:

       Continue to Grow Our Premier Position in National Accounts. From 2002 through 2005, revenue from our national accounts program increased at a compound annual growth rate of 10%. We plan to continue to invest in the expansion of this program. Through our national accounts program, we coordinate electrical MRO procurement and purchasing activities across multiple locations, primarily for large industrial and commercial companies and for electric utilities. We have well-established relationships with more than 290 companies, providing us with a recurring base of revenue through multi-year agreements with these companies. Our objective is to continue to increase revenue from our national account customers by:

       Extend Our Leadership Position in Integrated Supply Services. We believe we are the largest provider of integrated supply services for MRO goods and services in the United States. We provide a full complement of outsourcing solutions, focusing on improving the supply chain management process for our customers’ indirect purchases. Our integrated supply programs replace the traditional multi-vendor, resource-intensive procurement process with a single, outsourced, fully automated process capable of managing all MRO and related service requirements. Our solutions range from timely product delivery to assuming full responsibility for the entire procurement function. Our customers include some of the largest industrial companies in the United States. We plan to expand our leadership position as the largest integrated supply services provider in the United States by building upon established relationships within our large customer base and premier supplier network, to meet customer’s continued interest in outsourcing.

       Gain Share in Fragmented Local Markets. Significant opportunities exist to gain market share in highly fragmented local markets. We intend to increase our market share in key geographic markets through a combination of increased sales and marketing efforts at existing branches, acquisitions that expand our product and customer base and new branch openings. To promote this growth, we have a compensation system for branch managers that encourage them to increase sales and optimize business activities in their local markets, including managing the sales force, configuring inventories, targeting potential customers for marketing efforts and tailoring local service options.

       Expand our LEAN Initiative. LEAN is a company-wide, strategic initiative to drive continuous improvement across the entire enterprise, including sales, operations and administrative processes. The basic principles behind LEAN are to rapidly identify and implement improvements through simplification, elimination of waste and reducing errors throughout a defined process. We have been highly successful in applying LEAN in a distribution environment and have developed and deployed numerous initiatives through the Kaizen approach. The initiatives are primarily centered around our branch operations and target nine key areas: sales, pricing, warehouse operations, transportation, purchasing, inventory, accounts receivable, accounts payable and administrative processes. In 2006, our objective is to continue to implement the initiatives across our branch locations and headquarters operations, consistent with our long-term strategy of continuously refining and improving our processes to achieve both sales and operational excellence.

       Pursue Strategic Acquisitions. Since 1995, we have completed and successfully integrated 27 acquisitions. Our most recent acquisitions were completed in July and September 2005. We believe that the highly fragmented nature of the electrical and industrial MRO distribution industry will continue to provide us with acquisition opportunities. We expect that any future acquisitions will be financed with internally generated funds, additional debt and/or the issuance of equity securities. However, our ability to make acquisitions will be subject to our compliance with certain conditions under the terms of our revolving credit facility. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources,” for a further description of the revolving credit facility.

       Capitalize on Our Information System Capabilities. We intend to utilize our sophisticated information technology capabilities to drive increased sales performance and market share. Our information systems support targeted direct mail marketing campaigns, sales promotions, sales productivity and profitability assessments and coordination with suppliers and overall supply chain programs that improve customer profitability and enhance our working capital productivity. Our information systems provide us with detailed, actionable information across all facets of our broad network, allowing us to quickly and effectively identify and act on profitability and efficiency-related initiatives.

       Expand Our International Operations. Our international sales, the majority of which are in Canada, accounted for approximately 13% in 2005 and in the six months ended June 30, 2006, respectively. We believe that there is significant additional demand for our products and services outside the United States and Canada. Many of our multinational domestic customers are seeking distribution, integrated supply and project management solutions globally. We follow our established customers and pursue business that we believe utilizes and extends our existing capabilities. We believe this strategy of working through well-developed customer and supplier relationships significantly reduces risk and provides the opportunity to establish profitable incremental business. We currently have seven locations in Mexico. Additionally, our locations in Aberdeen, Scotland and London, England support our sales efforts in Europe and the former Soviet Union. We also have operations in Nigeria to serve West Africa, an office in Singapore to support our operations in Asia and an office in United Arab Emirates to serve the Middle East.

Competitive Strengths

       We believe the following strengths are central to the successful execution of our business strategy:

       Market Leadership. Our ability to manage large construction projects, complex multi-site plant maintenance programs, procurement projects that require special sourcing, technical advice, logistical support and locally based service has enabled us to establish leadership positions in our principal markets. We have utilized these skills to generate significant revenues in industries with intensive use of electrical and MRO products, including electrical contracting, utilities, OEM, process manufacturing and other commercial, institutional and governmental entities. We also have extended our position within these industries to expand our customer base.

       Value-added Services. We are a leader in providing a wide range of services and procurement solutions that draw on our product knowledge, supply and logistics expertise and systems capabilities, enabling our customers with large operations and multiple locations to reduce supply chain costs and improve efficiency. Our expansive geographical coverage is essential to our ability to provide these services. We have more than 370 branches to complement our national sales and marketing activities with local customer service, product

       Broad Product Offering. We provide our customers with a broad product selection consisting of more than 1,000,000 electrical, industrial, data communications, MRO and utility products sourced from more than 24,000 suppliers. Our broad product offering and stable source of supply enables us to meet virtually all of a customer’s electrical product and MRO requirements.

       Extensive Distribution Network. We are a full-line distributor of electrical supplies and equipment with operations in the United States, Canada, Mexico, Guam, the United Kingdom, Nigeria, United Arab Emirates and Singapore. We operate more than 370 branch locations and eight distribution centers (six in the United States and two in Canada). This extensive network, which would be extremely difficult and expensive to duplicate, allows us to:

       Low Cost Operator. Our competitive position has been enhanced by our low cost position, which is based on:

       As a result of these factors, we believe that our operating costs as a percentage of sales is one of the lowest in our industry. Our selling, general and administrative expenses as a percentage of revenues for the six months ended June 30, 2006 decreased to 13.0% from 13.9% for 2005, significantly below our peer group 2004 average of approximately 20%, according to the National Association of Electrical Distributors. Our low cost position enables us to generate a significant amount of net cash flow, as the amount of capital investment required to maintain our business is relatively low. Consequently, more of the cash we generate is available for debt reduction, continued investment in the growth of the business and strategic acquisitions.

Products

       Our network of branches and distribution centers stock more than 200,000 unique product SKUs. Each branch tailors its inventory to meet the needs of the customers in its local market, stocking an average of approximately 2,500 SKUs. Our business allows our customers to access more than 1,000,000 products.

       Representative products and services that we offer include:

       We purchase products from a diverse group of more than 24,000 suppliers. In 2005, our ten largest suppliers accounted for approximately 34% of our purchases. The largest of these was Eaton Corporation, through its Eaton Electrical division, accounting for approximately 12% of total purchases. No other supplier accounted for more than 5% of total purchases.

       Our supplier relationships are important to us, providing access to a wide range of products, technical training and sales and marketing support. We have preferred supplier agreements with more than 200 of our suppliers and purchase over 60% of our stock inventory pursuant to these agreements. Consistent with industry practice, most of our agreements with suppliers, including both distribution agreements and preferred supplier agreements, are terminable by either party on 60 days notice or less.

Services

       In conjunction with product sales, we offer customers a wide range of services and procurement solutions that draw on our product and supply management expertise and systems capabilities. These services include national accounts programs, integrated supply programs and major project programs. We are responding to the needs of our customers, particularly those in processing and manufacturing industries. To more efficiently manage the MRO process on behalf of our customers, we offer a range of supply management services, including:

       National Accounts Programs. The typical national account customer is a Fortune 500 industrial company, a large utility or other major customer, in each case with multiple locations. Our national accounts programs are designed to provide customers with total supply chain cost reductions by coordinating purchasing activity for MRO supplies and direct materials across multiple locations. Comprehensive implementation plans establish jointly managed teams at the local and national level to prioritize activities, identify key performance measures and track progress against objectives. We involve our preferred suppliers early in the implementation process, where they can contribute expertise and product knowledge to accelerate program implementation and the achievement of cost savings and process improvements.

       Integrated Supply Programs. Our integrated supply programs offer customers a variety of services to support their objectives for improved supply chain management. We integrate our personnel, product and distribution expertise, electronic technologies and service capabilities with the customer’s own internal resources to meet particular service requirements. Each integrated supply program is uniquely configured to deliver a significant reduction in the number of MRO suppliers, reduce total procurement costs, improve operating controls and lower administrative expenses. Our solutions range from just-in-time fulfillment to assuming full responsibility for the entire procurement function for all indirect purchases. We believe that customers will increasingly seek to utilize us as an “integrator,” responsible for selecting and managing the supply of a wide range of MRO and OEM products.

Markets and Customers

       We have a large base of approximately 100,000 customers diversified across our principal markets. No customer accounted for more than 4% of our total sales in 2005.

       Industrial Customers. Sales to industrial customers, which include numerous manufacturing and process industries and OEMs accounted for approximately 41% of our sales in 2005.

       MRO products are needed to maintain and upgrade the electrical and communications networks at industrial sites. Expenditures are greatest in the heavy process industries, such as food processing, metals, pulp and paper and petrochemical. Typically, electrical MRO is the first or second ranked product category by purchase value for total MRO requirements for an industrial site. Other MRO product categories include, among others, lubricants, pipe, valves and fittings, fasteners, cutting tools and power transmission products.

       OEM customers incorporate electrical components and assemblies into their own products. OEMs typically require a reliable, high-volume supply of a narrow range of electrical items. Customers in this market are particularly service and price sensitive due to the volume and the critical nature of the product used, and they also expect value-added services such as design and technical support, just-in-time supply and electronic commerce.

       Electrical Contractors. Sales to electrical contractors accounted for approximately 36% of our sales in 2005. These customers range from large contractors for major industrial and commercial projects, which represent the customer types we principally serve, to small residential contractors, which represent a small portion of our sales. Electrical products purchased by electrical subcontractors typically account for approximately 40% to 50% of their installed project cost, so therefore, accurate cost estimates and competitive material costs are critical to a contractor’s success in obtaining profitable projects.

       Utilities. Sales to utilities accounted for approximately 17% of our sales in 2005. This market includes large investor-owned utilities, rural electric cooperatives and municipal power authorities. We provide our utility customers with transmission and distribution products and an extensive range of supplies to meet their MRO and capital projects needs. Full materials

       Commercial, Institutional and Governmental (“CIG”) Customers. Sales to CIG customers accounted for approximately 6% of our sales in 2005. This fragmented market includes schools, hospitals, property management firms, retailers and government agencies of all types. We have a platform to sell integrated lighting control and distribution equipment in a single package for multi-site specialty retailers, restaurant chains and department stores.

Distribution Network

       Branch Network. We have more than 370 branches, of which approximately 310 are located in the United States, about 50 are located in Canada and the remainder located in Mexico, Puerto Rico, Guam, the United Kingdom, Nigeria, United Arab Emirates and Singapore. In addition to consolidations in connection with acquisitions, we occasionally open, close or consolidate existing branch locations to improve market coverage and operating efficiency.

       Distribution Centers. To support our branch network, we have eight distribution centers located in the United States and Canada, with facilities located near Pittsburgh, Pennsylvania, serving the Northeast and Midwest United States; near Reno, Nevada, serving the Western United States; near Memphis, Tennessee, serving the Southeast and Central United States; in Columbia, South Carolina, serving the Southeast United States; near Dayton, Ohio, serving the Midwest United States; in Little Rock, Arkansas, serving the Northeast, Central and Western United States; near Montreal, Quebec, serving Eastern and Central Canada; and near Vancouver, British Columbia, serving Western Canada.

       Our distribution centers add value for our branches, suppliers and customers through the combination of a broad and deep selection of inventory, online ordering, same-day shipment and central order handling and fulfillment. Our distribution center network reduces the lead-time and improves the reliability of our supply chain, giving us a distinct competitive advantage in customer service. Additionally, the distribution centers reduce the time and cost of supply chain activities through automated replenishment and warehouse management systems and economies of scale in purchasing, inventory management, administration and transportation.

Sales Organization

       Sales Force. Our general sales force is based at the local branches and comprises of approximately 2,100 of our employees, almost half of whom are outside sales representatives with the remainder being inside sales personnel. Outside sales representatives are paid under a compensation structure that is primarily weighted toward commissions. They are responsible for making direct customer calls, performing on-site technical support, generating new customer relations and developing existing territories. The inside sales force is a key point of contact for responding to routine customer inquiries such as price and availability requests and for entering and tracking orders.

       National Accounts. Our national accounts sales force comprises an experienced group of sales executives who negotiate and administer contracts, coordinate branch participation and identify sales and service opportunities. National accounts managers’ efforts target specific customer industries, including automotive, pulp and paper, petrochemical, steel, mining and food processing.

       We also have a sales management group, comprising our most experienced construction management personnel, which focus on serving the complex needs of North America’s largest engineering and construction firms and the top regional and national electrical contractors. These contractors typically specialize in large, complex projects such as building industrial sites, water treatment plants, airport expansions, healthcare facilities, correctional institutions, sports stadiums and convention centers.

       E-Commerce. Our primary e-business strategy is to serve existing customers by tailoring our catalog and Internet-based procurement applications to their internal systems or through their preferred technology and trading exchange partnerships. We continue to expand our e-commerce capabilities, meeting our customers’ requirements as they develop and implement their e-procurement business strategies. We have strengthened our business and technology relationships with the trading exchanges chosen by our customers as their e-procurement partners. We continue to enhance and enrich our customized electronic catalogs provided to our customers for use with their internal business systems. We believe that we lead our industry in rapid e-implementation to customers’ procurement systems and integrated procurement functionality using “punch-out” technology, a direct system-to-system link with our customers.

       We continue to enhance “WESCO Express,” a direct ship fulfillment operation responsible for supporting smaller customers and select national account locations. Customers can order from more than 83,000 electrical and data communications products stocked in our warehouses through a centralized customer service center or over the Internet at www.WESCOdirect.com. We also use a proactive sales approach utilizing catalogs, direct mail, e-mail and personal phone selling to provide a high level of customer service. Our 2005-2006 WESCO’s Buyers Guide^® was produced and released in 2005.

International Operations

       To serve the Canadian market, we operate a network of approximately 50 branches in nine provinces. Branch operations are supported by two distribution centers located near Montreal and Vancouver. With sales of approximately US$500 million, Canada represented approximately 11% of our total sales in 2005. The Canadian market for electrical distribution is considerably smaller than the U.S. market, with roughly US$4.3 billion in total sales in 2005, according to the Canadian Distribution Council.

       We also have seven locations in Mexico headquartered in Tlalnepantla, which serve all of metropolitan Mexico City and the Federal District and the states of Chihuahua, Hidalgo, Mexico, Morelos and Nuevo Leon.

       We sell to other international customers through domestic export sales offices located within North America and sales offices in international locations. Our operations in Aberdeen, Scotland and London, England support sales efforts in Europe, oil and gas customers on a global basis, engineering procurement companies and the former Soviet Union. We have an operation in Nigeria to serve West Africa, an office in United Arab Emirates to serve the Middle East and an office in Singapore to support our sales to Asia and global oil and gas customers. All of the international locations have been established to primarily serve our growing list of customers with global operations referenced under National Accounts above.

Management Information Systems

       We have implemented data processing systems to provide support for a full range of business functions, such as customer service, inventory and logistics management, accounting and administrative support. Our branch information system, known as WESNET, is the primary data processing vehicle for all branch operations (other than our Bruckner Integrated Supply Division and certain acquired branches). The WESNET system provides all of the basic day-to-day order management and order fulfillment functions. The WESNET application and server reside locally within each branch and provide us with a flexible and cost-effective approach to facilitate expansion and organizational growth. The distributed systems are connected to a centralized data processing center via a wide area network that provides a tightly coupled, yet flexible system.

       The centralized corporate information system and data warehouse provide a platform with capability that we believe exceeds many of the most advanced enterprise resource planning packages available on the market. Our centralized servers contain near real-time transactional data from each branch system, as well as multiple years of historical transaction data. The centralized server and data warehouse technology provide a cost-effective mechanism to better monitor, manage and enhance operational processes. These systems have become the principal technology supporting inventory management, purchasing management, automated stock replenishment, margin analysis, and financial and operating analytics.

       The data warehouse is also utilized to perform extensive operational analysis and provide detailed insight for all major business processes. By providing this technology, employees at all levels have the ability to analyze their area of responsibility and drive improvements through the organization. The system contains a variety of analytic tools, including activity-based costing capability for analyzing profitability by customer, sales representative, product type and shipment type. Many other tools permit analysis of sales and margins, supplier sales planning, item analysis, market analysis, product insight and many other operational reporting and trending applications.

       The centralized platform facilitates the processing of customer orders, shipping notices, suppliers’ purchase orders and funds transfer via EDI. We have long supported standard EDI with many trading partners. Over the years we have added capability to support several other integration vehicles beyond standard EDI to better support our customers’ needs. The evolving integration capability allows us to seamlessly connect our information systems platform with those of our customers and suppliers. Our e-commerce purchasing and order fulfillment platform is a user-friendly platform that will be integrated with our legacy systems.

Competition

       We believe that we are the largest distributor in the estimated $74 billion* U.S. electrical distribution industry and the largest provider of integrated supply services for MRO goods and services in the United States. We operate in a highly competitive and fragmented industry. We compete directly with national, regional and local providers of electrical and other industrial MRO supplies. In 2004, the latest year for which industry-published market share data is available, the four national distributors, including us, accounted for approximately 18% of estimated total industry sales. Competition is primarily focused on the local service area, and is generally based on product line breadth, product availability, service capabilities and price. Another source of competition is buying groups formed by smaller distributors to increase purchasing power and provide some cooperative marketing capability. While increased buying power may improve the competitive position of buying groups locally, we believe these groups have not been able to compete effectively with us for national account customers due to the difficulty in coordinating a diverse ownership group. Although certain Internet-based procurement service companies, auction businesses and trade exchanges remain in the marketplace, the impact on our business from these potential competitors has been minimal to date.

Employees

       As of June 30, 2006, we had approximately 6,150 employees worldwide, of which approximately 5,430 were located in the United States and approximately 720 in Canada and our other international locations. Less than 5% of our employees are represented by unions. We believe our labor relations are generally good.

Intellectual Property

       We currently have trademarks and service marks registered with the U.S. Patent and Trademark Office. The registered trademarks and service marks include: “WESCO^®”, our corporate logo, the running man logo, the running man in box logo and “The Extra Effort People^®”. In 2005, two trademarks, “CB Only the Best is Good Enough” and “LADD,” were added as a result of the acquisition of Carlton-Bates. Certain of these and other trademark and service mark registration applications have been filed in various foreign jurisdictions, including Canada, Mexico, the United Kingdom, Singapore and the European Community.

Environmental Matters

       Our facilities and operations are subject to federal, state and local laws and regulations relating to environmental protection and human health and safety. Some of these laws and regulations may impose strict, joint and several liabilities on certain persons for the cost of investigation or remediation of contaminated properties. These persons may include former, current or future owners or operators of properties and persons who arranged for the disposal of hazardous substances. Our owned and leased real property may give rise to such

       *Electrical wholesale estimated industry sales per Electrical Wholesaling (November, 2005) based upon U.S. Census Bureau Survey segregating electrical wholesale vs. electrical retail sales. Electrical Wholesaling’s 2004 estimated industry sales of $83 billion had aggregated wholesale and retail sales.

       We believe that we are in compliance, in all material respects, with applicable environmental laws. As a result, we do not anticipate making significant capital expenditures for environmental control matters either in the current year or in the near future.

Seasonality

       Our operating results are not significantly affected by seasonal factors. Sales during the first quarter are generally less than 2% below the sales of the remaining three quarters due to a reduced level of activity during the winter months of January and February. Sales increase beginning in March, with slight fluctuations per month through December. As a result, our reported sales and earnings in the first quarter are generally lower than in subsequent quarters.

PROPERTIES

       We have approximately 370 branches, of which approximately 310 are located in the United States, approximately 50 are located in Canada and the remainder are located in Mexico, Puerto Rico, Guam, the United Kingdom, Nigeria, United Arab Emirates and Singapore. Approximately 25% of our branches are owned facilities, and the remainder are leased.

       The following table summarizes our distribution centers:

LEGAL PROCEEDINGS

       From time to time, a number of lawsuits and claims have been or may be asserted against us relating to the conduct of our business, including routine litigation relating to commercial and employment matters. The outcome of any litigation cannot be predicted with certainty, and some lawsuits may be determined adversely to us.
