PART I

Item 1. Business.

In this Annual Report onForm 10-K, “WESCO” refers to WESCO International, Inc., and its subsidiaries and its predecessors unless the context otherwise requires. References to “we,” “us,” “our” and the “Company” refer to WESCO and its subsidiaries.

The Company

WESCO International, Inc. (“WESCO International”), incorporated in 1993 and effectively formed in February 1994 upon acquiring a distribution business from Westinghouse Electric Corporation, is a leading North American based distributor of products and provider of advanced supply chain management and logistics services used primarily in industrial, construction, utility and commercial, institutional and government (“CIG”) markets. We are a leading provider of electrical, industrial, and communications maintenance, repair and operating (“MRO”) and original equipment manufacturers (“OEM”) products, construction materials, and advanced supply chain management and logistics services. Our primary product categories include general electrical and industrial supplies, wire, cable and conduit, data and broadband communications, power distribution equipment, lighting and lighting control systems, control and automation, motors, and safety.

We serve over 75,000 active customers globally through approximately 475 full service branches and nine distribution centers located in the United States, Canada, and Mexico with offices in 15 additional countries. The Company employs approximately 9,200 employees worldwide. We distribute over 1,000,000 products, grouped into six categories, from more than 25,000 suppliers utilizing a highly automated, proprietary electronic procurement and inventory replenishment system.

In addition, we offer a comprehensive portfolio of value-added capabilities, which includes supply chain management, logistics and transportation, procurement, warehousing and inventory management, as well as kitting, limited assembly of products and system installation. Our value-added capabilities, extensive geographic reach, experienced workforce and broad product and supply chain solutions have enabled us to grow our business and establish a leading position in North America.

In December 2012, we completed the acquisition of EECOL Electric Corporation ("EECOL") with approximately $0.9 billion in annual sales, approximately 57 locations across Canada and approximately 20 in South America, and more than 20,000 customers.

Industry Overview

We operate in highly fragmented markets that include thousands of small regional and locally based, privately owned competitors. According to one industry publication, in 2012, the latest year for which market share data is available, the five largest North American electrical distributors, including WESCO, accounted for only approximately 29% of all industry sales in North America. Our global account, integrated supply and OEM programs provide customers with a regional, national, North American and global supply chain consolidation opportunities. The demand for these programs has grown in recent years, driven primarily by the desire of companies to reduce operating expenses by outsourcing operational and administrative functions associated with the procurement, management and utilization of MRO supplies and OEM components. We believe that significant opportunities exist for further expansion of these programs. The total potential in the United States for purchases of MRO and OEM supplies and services across all industrial distribution market segments and channels is currently estimated to be greater than $500 billion per an industry study.

According to management estimates, electrical distribution industry sales have grown at an approximately 4% compound 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, the proliferation of enhanced building and safety codes, and use of the internet. Wholesale distributors have also grown as a result of a long-term shift in procurement preferences that favor the use of distributors over direct relationships with manufacturers. It is estimated that approximately 75% of electrical products sold in the United States are delivered to the end user through the distribution channel.

Markets and Customers

We have a large base of over 75,000 active customers across a diverse set of end markets. Our top ten customers accounted for approximately 10% of our sales in 2013. No one customer accounted for more than 2% of our sales in 2013.

The following table outlines our sales breakdown by end market:

Year Ended December 31,	2013	2012	2011
(percentages based on total sales)
Industrial	43%	44%	43%
Construction	32%	32%	35%
Utility	13%	12%	11%
Commercial, Institutional and Governmental	12%	12%	11%

Industrial. Sales to industrial customers of MRO, OEM, and construction products and services accounted for approximately 43% of our sales in 2013, compared to 44% in 2012. Industrial sales product categories include a broad range of electrical equipment and supplies as well as lubricants, pipe, valves, fittings, fasteners, cutting tools, power transmission, and safety products. In addition, OEM customers require a reliable supply of assemblies and components to incorporate into their own products as well as value-added services such as supplier consolidation, design and technical support, just-in-time supply and electronic commerce, and supply chain management.

Construction. Sales of electrical and communications products to contractors accounted for approximately 32% of our sales in 2013 and 2012. Customers include a wide array of contractors and engineering, procurement and construction firms for industrial, infrastructure, commercial and data and broadband communications projects. Specific applications include projects for refineries, railways, hospitals, wastewater treatment facilities, data centers, security installations, offices, and modular and mobile homes. In addition to a wide array of electrical products, we offer contractors communications products for projects related to IT/network modernization, physical security upgrades, broadband deployments, network security, and disaster recovery.

Utility. Sales to utilities and utility contractors accounted for approximately 13% of our sales in 2013, compared to 12% in 2012. Customers include large investor-owned utilities, rural electric cooperatives, municipal power authorities and contractors that serve these customers. We provide our utility customers with products and services to support the construction and maintenance of their generation, transmission and distribution systems along with an extensive range of products that meet their power plant MRO and capital projects needs. Materials management and procurement outsourcing arrangements are also important in this market, as cost pressures and deregulation have caused utility customers to seek improvements in the efficiency and effectiveness of their supply chains.

Commercial, Institutional and Governmental ("CIG"). Sales to CIG customers accounted for approximately 12% of our sales in 2013 and 2012. Customers include schools, hospitals, property management firms, retailers and federal, state and local government agencies of all types, including federal contractors.

Business Strategy

Our goal is to grow organically at a rate greater than that of our industry while also making accretive acquisitions. Our organic growth strategy leverages our existing strengths and focuses on initiatives to enhance our sales and customer service, develop new end markets, broaden our product and service offerings and expand our geographic footprint. We utilize LEAN continuous improvement initiatives on a company-wide basis to deliver operational excellence and improve productivity. We also extend our LEAN initiatives to customers to improve the efficiency and effectiveness of their operations and supply chains. In addition, we seek to generate a distinct competitive advantage through talent management and employee development processes and programs.

We have identified certain growth engines that we believe provide substantial opportunities for above market growth. These growth engines include business models, selected end markets and product categories. The end markets are construction, government, international, and utility. The product categories are communications and security products, and lighting and sustainability. We believe our business models of global accounts and integrated supply programs also provide significant growth opportunities and are applicable to any of our served end markets. We have focused our growth efforts on these end markets, product categories, and business models as discussed below.

Grow Our Global Account Customer Relationships and Base. Our typical global account customer is a Fortune 1000 industrial or commercial company, a large utility, a major contractor, or a governmental or institutional customer, in each case with multiple locations. Our global account program is designed to provide customers with supply chain management services

3

and cost reductions by coordinating and standardizing activity for MRO materials and OEM direct materials across their multiple locations utilizing our broad geographic footprint and our largely integrated information technology platform. Comprehensive implementation plans are managed at the local, national and international levels 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 achievement of cost savings and process improvements.

Growth from our global account programs is an important component of our organic growth strategy. Our objective is to continue to increase revenue from our global account programs by expanding our product and service offerings to existing global account customers and expanding our reach to serve additional customer locations. We also plan on expanding our customer base by capitalizing on our industry expertise and supply chain optimization capabilities.

Extend Our Leadership Position in Integrated Supply Programs. Our integrated supply programs are focused on customers in the industrial, utility, construction and CIG markets. We combine our personnel, product and distribution expertise, electronic commerce technologies, and service capabilities with the customer's own internal resources to meet particular service requirements. Each integrated supply program is configured to reduce the number of suppliers, total procurement costs, and administrative expenses as well as improve operating controls. Our integrated supply programs focus on supply chain optimization and replace the traditional multi-vendor, resource-intensive procurement process with a single, outsourced, automated process. Our services range from timely product delivery to an outsourced procurement function. We believe that large customers will increasingly seek to utilize such services to consolidate and manage their MRO and OEM supply chains. We plan to expand our position as an integrated supply services leader in North America by building upon established relationships within our large customer base and premier supplier network, and extending our services to additional customers and locations around the world.

Expand Our Relationships with Construction Contractors. Our construction sales are focused on contractors, particularly those involved with healthcare, government facilities, enterprise data communications, telecommunication and energy and government infrastructure-related projects. We believe that significant cross selling opportunities exist for electrical and communications products and we intend to use our global account and integrated supply programs, LEAN initiatives and project management expertise to capitalize on construction business opportunities.

Expand Products and Services for Utilities. Our utility customers continue to focus on improving grid reliability as well as improving their operating efficiency and reducing costs.  As a result, we anticipate an increase in distribution grid improvement and transmission expansion projects as well as the adoption of integrated supply programs. Accordingly, we are focused on expanding our logistical and project services, integrated supply services and project management programs to increase our scope of supply on distribution grid, generation and other energy projects, including alternative energy projects.

Expand International Operations. We seek to capitalize on existing and emerging international market opportunities through local business development and the expansion of our global product and service platforms while taking advantage of acquisitions that expand our global footprint. We target large, growing markets where we can leverage our value proposition and relationships with key customers and suppliers. We believe this strategy of working with well-developed customer and supplier relationships significantly reduces risk and provides the opportunity to establish profitable business. Our priorities are focused on global vertical markets including energy, mining and metals, manufacturing, and infrastructure, as well as key product categories such as communications and security. Additionally, we are extending our procurement outsourcing and integrated supply programs following large, existing customers into international markets.

Grow Our Communications Products Position. Over the last several years, there has been a convergence of electrical and data communications contractors. Our ability to provide both electrical and communications products and services lines as well as automation, electromechanical, non-electrical MRO, physical security and utility products has presented cross selling opportunities across WESCO. Communications products have continued to be in demand due to networking upgrades, low voltage security investments, data center upgrades and increasing broadband and telecommunications utilization.

Grow Lighting System and Sustainability Sales. Lighting applications are undergoing significant innovation driven by energy efficiency and sustainability trends. We expanded our sales team and marketing initiatives and will continue to add resources in this product category and in product and service offerings to provide overall energy solutions. We opened our second Lighting & Sustainability Solutions Center to increase the customer's knowledge in lighting technology and solutions that contribute to an environmentally responsible future.

Pursue Strategic Acquisitions. In the first quarter of 2014 we completed the previously announced acquisition of LaPrairie, Inc., a wholesale distributor of electrical products located in Ontario, with annual sales of approximately $30 million. Our acquisitions of RS Electronics, Trydor Industries, Conney Safety, and EECOL Electric were completed in 2012 and our efforts focused on integrating these companies into WESCO in 2013. We believe that the highly fragmented nature of the electrical and industrial distribution industry will continue to provide acquisition opportunities. We expect that any future acquisitions will be financed with internally generated funds, additional debt and/or the issuance of equity securities.

Drive Operational Excellence. LEAN continuous improvement is a set of company-wide strategic initiatives to increase efficiency and effectiveness across the entire business enterprise, including sales, operations and administrative processes. The basic principles behind LEAN are to systematically identify and implement improvements through simplification, elimination of waste and reduction in errors. We apply LEAN in our distribution environment, and develop and deploy numerous initiatives through the Kaizen approach targeting improvements in sales, margin, warehouse operations, transportation, purchasing, inventory, accounts receivable, accounts payable, and administrative processes. Our objective is to continue to implement LEAN initiatives across our business enterprise and to extend LEAN services to our customers and suppliers.

Talent Management. Our strategy is to develop a distinct competitive advantage through talent management and employee engagement and development. We believe our ability to attract, develop and retain diverse human capital is imperative to ongoing business success. We improve workforce capability through various programs and processes that identify, recruit, develop and promote our talent base. Significant enhancements in these programs have been made over the last several years, and we expect to continue to refine and enhance these programs in the future.

The following table sets forth sales information about our sales by product category:

Year Ended December 31,	2013	2012	2011
(percentages based on total sales)
General and Industrial Supplies	40%	36%	34%
Wire, Cable and Conduit	16%	17%	18%
Data and Broadband Communications	14%	15%	17%
Power Distribution Equipment	11%	13%	11%
Lighting and Controls	10%	9%	9%
Control, Automation and Motors	9%	10%	11%

We purchase products from a diverse group of more than 25,000 suppliers. In 2013, our ten largest suppliers accounted for approximately 31% of our purchases. Our largest supplier accounted for approximately 12% of our total purchases. No other supplier accounted for more than 5% of our 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 over 300 preferred supplier arrangements and purchase over 60% of our products pursuant to these arrangements. 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

As part of our overall offering, we provide customers a comprehensive portfolio of value added services which includes more than 50 value add solutions in 11 categories including construction, e-business, energy, engineering services, green and sustainability, production support, safety and security, supply chain optimization, training, and working capital. These solutions are designed to address our customer’s business needs through:

• Providing technical support for manufacturing process improvements;

• Implementing inventory optimization programs, including just-in-time delivery and vendor managed inventory;

• Participating in joint cost savings teams;

• Assigning our employees as on-site support personnel;

• Consulting and recommending energy-efficient product upgrades; and

• Offering safety and product training for customer employees.

Competitive Strengths

We compete directly with global, national, regional and local distributors of electrical and other industrial supplies. Competition is primarily focused on the local service area, and is generally based on product line breadth, product availability, service capabilities and price. We also compete with 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 it is difficult to coordinate a diverse ownership group to provide consistent quality products and services across multiple geographic regions. Although certain Internet-based procurement service companies, auction businesses and trade exchanges remain in the marketplace, the impact on our business from these competitors has not been significant to date.

Market Leadership. Our ability to manage complex global supply chains, multi-site facility maintenance programs and construction projects that require special sourcing, technical advice, logistical support and locally based service has enabled us to establish a strong presence in our served markets. We have utilized these skills to generate significant revenues in a broad range of industries with intensive use of electrical and industrial products.

Broad Product Offering and Value-added Services. We provide a wide range of products, services and procurement solutions, which draw on our product knowledge, supply and logistics expertise, system capabilities and supplier relationships to enable our customers to maximize productivity, minimize waste, improve efficiencies, reduce costs and enhance safety. Our broad product offering and stable source of supply enables us to consistently meet virtually all of a customer’s capital project, product, MRO and OEM requirements.

Extensive Distribution Network. We operate approximately 475 geographically dispersed branch locations and nine distribution centers (five in the United States and four in Canada). Our distribution centers add value for our customers, suppliers, and branches through the combination of a broad and deep selection of inventory, online ordering, next-day shipment and central order handling and fulfillment. Our distribution center network reduces the lead-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. This extensive network, which would be difficult and expensive to duplicate, provides us with a distinct competitive advantage and allows us to:

• Enhance localized customer service, technical support and sales coverage;

• Tailor individual branch products and services to local customer needs; and

• Offer multi-site distribution capabilities to large customers and global accounts.

Low Cost Operator. Our competitiveness has been enhanced by our consistent favorable operating cost position, which is based on use of LEAN, strategically-located distribution centers, and purchasing economies of scale. As a result of these factors and others, our operating cost 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 2013 were 13.3%.

United States. To serve our customers in the United States, we operate a network of approximately 325 branches supported by five distribution centers located in Pennsylvania, Nevada, Mississippi, Wisconsin, and Arkansas. Sales in the United States represented approximately 70% of our total sales in 2013. According to the Electrical Wholesaling Magazine, the U.S. electrical wholesale distribution industry had estimated sales of approximately $95 billion in 2013.

Canada. To serve our Canadian customers, we operate a network of approximately 105 branches in nine provinces. Branch operations are supported by four distribution centers located in Edmonton, Montreal, Toronto, and Vancouver. Sales in Canada represented approximately 25% of our total sales in 2013. Total annual electrical industry sales in Canada are approximately $7.5 billion through December 31, 2013 according to a recent publication.

Mexico. We have 10 branch locations in Mexico. Our headquarters in Tlalnepantla Estado de Mexico operates similar to a distribution center to enhance the service capabilities of the local branches. Sales in Mexico represented approximately 1% of our total sales in 2013.

Other International. We sell to global customers through export sales offices located in Miami, Houston, Pittsburgh, Montreal, and Calgary within North America and sales offices and branch operations in various international locations. Sales from other international locations represented approximately 4% of our total sales in 2013. Our branches in Aberdeen, Scotland, Dublin, Ireland and Manchester, England support sales efforts in Europe and the Middle East. We have a branch in Singapore to support our sales to Asia, a branch in Perth to serve customers in Australia, and a branch near Shanghai to serve customers in China along with operations in nine additional countries. The EECOL acquisition expanded WESCO's footprint into South America. All of our international locations have been established to serve our growing list of customers with global operations.

Intellectual Property

We currently have trademarks, patents and service marks registered with the U.S. Patent and Trademark Office and Canadian Intellectual Property Office. The trademarks and service marks registered in the U.S. include: “WESCO^®”, our corporate logo and the running man logo. The Company's "EECOL" trademark is registered in Canada. In addition, trademarks, patents, and service mark applications have been filed in various foreign jurisdictions, including Canada, Mexico, Chile, the United Kingdom, Singapore, China, Hong Kong, Thailand 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 investigation, remediation and monitoring liabilities under environmental laws. In addition, anyone disposing of certain products we distribute, such as ballasts, fluorescent lighting and batteries, must comply with environmental laws that regulate certain materials in these products.

7

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 affected by a reduced level of activity. Sales during the second, third and fourth quarters are generally 4-6% higher than the first quarter. Sales typically increase beginning in March, with slight fluctuations per month through October. During periods of economic expansion or contraction our sales by quarter have varied significantly from this seasonal pattern.

Item 1A. Risk Factors.

The following factors, among others, could cause our actual results to differ materially from the forward-looking statements we make. All forward-looking statements attributable to us or persons working on our behalf are expressly qualified by the following factors. This information should be read in conjunction with Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, Item 7A, Quantitative and Qualitative Disclosures about Market Risks and the consolidated financial statements and related notes included in this Form 10-K.

Adverse conditions in the global economy and disruptions of financial markets could negatively impact our results of operations.

Our results of operations are affected by the level of business activity of our customers, which in turn is affected by global economic conditions and market factors impacting the industries and markets that they serve. Certain global economies and markets continue to experience significant uncertainty and volatility. Adverse economic conditions or lack of liquidity in various markets, particularly in North America, may adversely affect our revenues and operating results. Economic and financial market conditions also affect the availability of financing for projects and for our customers' capital or other expenditures, which can result in project delays or cancellations and thus affect demand for our products. There can be no assurance that any governmental responses to economic conditions or disruptions in the financial markets ultimately will stabilize the markets or increase our customers' liquidity or the availability of credit to our customers. Should one or more of our larger customers declare bankruptcy, it could adversely affect the collectability of our accounts receivable, bad debt reserves and net income. In addition, our ability to access the capital markets may be restricted at a time when we would like, or need, to do so. The global economic and financial environment also may affect our business and financial condition in ways that we currently cannot predict, and there can be no assurance that global economic and market conditions will not adversely affect our results of operations, cash flow or financial position in the future. Fluctuations of the U.S. dollar relative to other currencies could negatively affect our business, financial results and liquidity.

Certain events or conditions could lead to interruptions in our operations, which may materially adversely affect our business, financial condition or results of operations.

    We operate a number of facilities and we coordinate company activities, including information technology systems and administrative services and the like, through our headquarters operations. Our operations depend on our ability to maintain existing systems and implement new technology, which includes allocating sufficient resources to periodically upgrade our information technology systems, and to protect our equipment and the information stored in our databases against both manmade and natural disasters, as well as power losses, computer and telecommunications failures, technological breakdowns, unauthorized intrusions, cyber-attacks, and other events. Conversions to new information technology systems may result in cost overruns, delays or business interruptions. If our information technology systems are disrupted, become obsolete or do not adequately support our strategic, operational or compliance needs, it could result in competitive disadvantage and adversely affect our financial results and business operations, including our ability to process orders, receive and ship products, maintain inventories, collect accounts receivable and pay expenses.

Because we rely heavily on information technology both in serving our customers and in our enterprise infrastructure in order to achieve our objectives, we may be vulnerable to damage or intrusion from a variety of cyber-attacks including computer viruses, worms or other malicious software programs that access our systems. Despite the precautions we take to mitigate the risks of such events, an attack on our enterprise information technology system could result in theft or disclosure of our proprietary or confidential information or a breach of confidential customer or employee information. Such events could have an adverse impact on revenue, harm our reputation, and cause us to incur legal liability and costs, which could be significant, to address and remediate such events and related security concerns.

We also depend on accessible office facilities, distribution centers and information technology data centers for our operations to function properly. 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. Such disaster related risks and effects are not predictable with certainty and, although they typically can be mitigated, they cannot be eliminated. We seek to mitigate our exposures to disaster events in a number of ways. For example, where feasible, we design the configuration of our facilities to reduce the consequences of disasters. We also maintain insurance for our facilities against casualties and we evaluate our risks and develop contingency plans for dealing with them. Although we have reviewed and analyzed a broad range of risks applicable to our business, the ones that actually affect us may not be those we have concluded most likely to occur. Furthermore, although our reviews have led to more systematic contingency planning, our plans are in varying stages of development and execution, such that they may not be adequate at the time of occurrence for the magnitude of any particular disaster event that befalls us.

10

Loss of key suppliers, product cost fluctuations, lack of product availability or inefficient supply chain operations 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 2013 accounted for approximately 31% of our purchases for the period. Our largest supplier in 2013 was Eaton Corporation accounting for approximately 12% of our purchases. The loss of, or a substantial decrease in the availability of, products from any of these suppliers, a supplier's change in sales strategy to rely less on distribution channels, 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, effects of economic or financial market conditions on a supplier's operations, 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. 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. The profitability of our business is also dependent upon the efficiency of our supply chain. An inefficient or ineffective supply chain strategy or operations could increase operational costs, reduce profit margins and adversely affect our business.

Expansion into new business activities, industries, product lines or geographic areas could subject the company to increased costs and risks and may not achieve the intended results.

Engaging in or significantly expanding business activities in product sourcing, sales and services could subject the company to unexpected costs and risks. Such activities could subject us to increased operating costs, product liability, regulatory requirements and reputational risks. Our expansion into new and existing markets, including manufacturing related or regulated businesses, may present competitive, distribution and regulatory challenges that differ from current ones. We may be less familiar with the target customers and may face different or additional risks, as well as increased or unexpected costs, compared to existing operations. Growth into new markets may also bring us into direct competition with companies with whom we have little or no past experience as competitors. To the extent we are reliant upon expansion into new geographic, industry and product markets for growth and do not meet the new challenges posed by such expansion, our future sales growth could be negatively impacted, our operating costs could increase, and our business operations and financial results could be negatively affected.

An increase in competition could decrease sales or earnings.

     We operate in a highly competitive industry and compete directly with global, national, regional and local providers of our products and services. Some of our existing competitors have, and new market entrants may have, greater resources than us. 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 as well as e-commerce companies.

Existing or future competitors may seek to gain or retain market share by reducing prices, and we may be required to lower our prices or may lose business, which could adversely affect our financial results. Also, to the extent that we do not meet changing customer preferences or demands or to the extent that one or more of our competitors becomes more successful with private label products or otherwise, our ability to attract and retain customers could be materially adversely affected. 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.

With the acquisition of EECOL Electric Corporation, our risk profile may differ materially from prior years as a result of increased levels of international operations, which could materially change our results of operations.

               On December 14, 2012 we completed our largest acquisition to date when we acquired EECOL Electric Corporation for approximately $1.1 billion.  EECOL is headquartered in Calgary, Alberta with approximately 57 locations throughout Canada and approximately 20 locations in South America.  While there are risks associated with acquisitions generally, including integration risks, there are additional risks more specifically associated with owning and operating businesses internationally, including those arising from import and export controls, exchange rate fluctuations, material developments in political, regulatory or economic conditions impacting those operations and various environmental and climatic conditions in particular areas of the world. Following this acquisition, a greater percentage of our revenues and expenses arise from international sources that may be subject to these risks from time to time. 

11

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 expanded our operations through organic growth and selected acquisitions of businesses and assets and may seek to do so in the future. Acquisitions involve various inherent risks, including: problems that could arise from the integration of the acquired business; uncertainties in assessing the value, strengths, weaknesses, contingent and other liabilities and potential profitability of acquisition candidates; the potential loss of key employees of an acquired business; the ability to achieve identified operating and financial synergies anticipated to result from an acquisition or other transaction; unanticipated changes in business, industry or general economic conditions that affect the assumptions underlying the acquisition or other transaction rationale; and expansion into new countries or geographic markets where we may be less familiar with operating requirements, target customers and regulatory compliance. Any one or more of these factors could increase our costs or cause us not to realize the benefits anticipated to result from the acquisition of business or assets.

We must attract, retain and motivate key employees, and the failure to do so may adversely affect our business and results of operations.

     Our success depends on hiring, retaining and motivating key employees, including executive, managerial, sales, technical, marketing and support personnel. We may have difficulty locating and hiring qualified personnel. In addition, we may have difficulty retaining such personnel once hired, and key people may leave and compete against us. The loss of key personnel or our failure to attract and retain other qualified and experienced personnel could disrupt or adversely affect our business, its sales and results of operations. In addition, our operating results could be adversely affected by increased costs due to increased competition for employees, higher employee turnover, which may also result in loss of significant customer business, or increased employee benefit costs.

We are subject to costs and risks associated with laws and regulations affecting our business, as well as litigation for product liability or other matters affecting our business.

     The complex legal and regulatory environment exposes us to compliance costs and risks, as well as litigation and other legal proceedings, that could materially affect our operations and financial results. These laws and regulations may change, sometimes significantly, as a result of political or economic events. They include tax laws and regulations, import and export laws and regulations, government contracting laws and regulations, labor and employment laws and regulations, product safety, occupational safety and health laws and regulations, securities and exchange laws and regulations (and other laws applicable to publicly-traded companies such as the Foreign Corrupt Practices Act), and environmental laws and regulations. In addition, proposed laws and regulations in these and other areas, such as healthcare, employment, or legal matters could affect the cost of our business operations. From time to time we are involved in legal proceedings which may relate to, for example, product liability, labor and employment (including wage and hour), tax, import and export compliance, worker health and safety, general commercial and securities matters. While we believe that the outcome of any pending matter is unlikely to have a material adverse effect on our financial condition or liquidity, additional legal proceedings may arise in the future and the outcome of any legal proceedings and other contingencies could require us to take actions which could adversely affect our operations or could require us to pay substantial amounts of money.

Because we conduct business in many countries, we are subject to income taxes as well as non-income based taxes in both the United States and various foreign jurisdictions. As a result, we are required to interpret the income tax laws and rulings in each jurisdiction in which we operate and are subject to ongoing tax audits in various jurisdictions. Due to ambiguity of tax laws in certain of these jurisdictions and the subjective nature of factual determinations, the respective taxing authorities may disagree with certain positions we have taken and assess additional taxes. While we regularly evaluate the likely outcomes of these audits in order to determine the appropriateness of our tax provision, there can be no assurance that we will accurately predict the outcomes of these audits, and the actual outcomes could adversely affect our results of operations.

Our outstanding indebtedness requires debt service commitments that could adversely affect our ability to fulfill our obligations and could limit our growth and impose restrictions on our business.

     As of December 31, 2013, we had $1,662.4 million of consolidated indebtedness (excludes debt discount), including $300.2 million in aggregate principal amount of term loans due 2019 (the “Term Loans”), $500.0 million in aggregate principal amount of 5.375% Senior Notes due 2021 (the “2021 Notes”) and $344.9 million in aggregate principal amount of 6.0% Convertible Senior Debentures due 2029 (the “2029 Debentures”). Our consolidated indebtedness also includes our revolving credit facility (the "Revolving Credit Facility"), which has an aggregate borrowing capacity of $600.0 million, and our accounts receivable securitization facility (the “Receivables Facility”), through which we sell up to $500.0 million of our accounts

12

receivable to third-party financial institutions. We and our subsidiaries may undertake additional borrowings in the future, subject to certain limitations contained in the instruments governing our indebtedness.

     Our debt service obligations have important consequences, including: our payments of principal and interest reduce the funds available to us for operations, future business opportunities and acquisitions and other purposes; they increase our vulnerability to adverse economic, financial market and industry conditions; our ability to obtain additional financing may be limited; they may hinder our ability to adjust rapidly to changing market conditions; we may be required to incur additional interest due to the contingent interest features of the 2029 Debentures, which are embedded derivatives; and our financial results are affected by increased interest costs. Our ability to make scheduled payments of principal and interest on our debt, refinance our indebtedness, make scheduled payments on our operating leases, fund planned capital expenditures or to finance acquisitions will depend on our future performance, which, to a certain extent, is subject to economic, financial, competitive and other factors beyond our control. There can be no assurance that our business will continue to generate sufficient cash flow from operations in the future to service our debt, make necessary capital expenditures or meet other cash needs. If unable to do so, we may be required to refinance all or a portion of our existing debt, to sell assets or to obtain additional financing. Our Revolving Credit Facility is subject to renewal in August 2016 and our Receivables Facility is subject to renewal in September 2016. There can be no assurance that available funding or any sale of additional receivables or additional financing will be possible at the times of renewal in amounts or terms favorable to us, if at all.

Over the next three years, we will be required to repay approximately $520.6 million of our currently outstanding indebtedness, of which $22.6 million is related to our Revolving Credit Facility, $453.6 million is related to our Receivables Facility, $37.6 million is related to our international lines of credit, and $4.2 million is related to our Term Loans.

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

     Our credit facilities also require us to maintain specific earnings to fixed expenses and to meet minimum net worth requirements in certain circumstances. Our Term Loan, 2021 Notes and credit facilities 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: incur additional debt or issue guarantees; create liens; make certain investments; enter into transactions with our affiliates; sell certain assets; make capital expenditures; redeem capital stock or make other restricted payments; declare or pay dividends or make other distributions to stockholders; and merge or consolidate with any person. Our Term Loan and credit facilities contain additional affirmative and negative covenants, and 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 the 2029 Debentures, the 2021 Notes, the credit facilities, the Term Loan, 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.

Goodwill and indefinite life intangible assets recorded as a result of our acquisitions could become impaired.

     As of December 31, 2013, our combined goodwill and indefinite life intangible assets amounted to $1,837.4 million. To the extent we do not generate sufficient cash flows to recover the net amount of any investments in goodwill and other indefinite life intangible assets recorded, the investment could be considered impaired and subject to write-off. We expect to record further goodwill and other indefinite life intangible assets as a result of future acquisitions we may complete. Future amortization of such assets or impairments, if any, of goodwill or indefinite life intangible assets would adversely affect our results of operations in any given period.

There is a risk that the market value of our common stock may decline.

     Stock markets have experienced significant price and trading volume fluctuations, and the market prices of companies in our industry have been volatile. In recent years, volatility and disruption reached unprecedented levels. For some issuers, the markets have exerted downward pressure on stock prices and credit capacity. It is impossible to predict whether the price of our common stock will rise or fall. Trading prices of our common stock will be influenced by our operating results and prospects and by global economic, financial and other factors.

Future sales of our common stock in the public market or issuance of securities senior to our common stock could adversely affect the trading price of our common stock and the value of the 2029 Debentures.

13

     Future sales of substantial amounts of our common stock or equity-related securities in the public market, or the perception that such sales could occur, could adversely affect prevailing trading prices of our common stock and the value of the 2029 Debentures and could impair our ability to raise capital through future offerings of equity or equity-related securities. No prediction can be made as to the effect, if any, that future sales of shares of common stock or the availability of shares of common stock for future sale will have on the trading price of our common stock or the value of the 2029 Debentures.

There may be future dilution of our common stock.

     To the extent options to purchase common stock under our stock option plans are exercised, holders of our common stock will incur dilution. Additionally, our 2029 Debentures include contingent conversion price provisions and options for settlement in shares. Based on our current stock price, the 2029 Debentures may be converted into common stock which would increase dilution to our stockholders.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

We have approximately 475 branches, of which approximately 325 are located in the United States, approximately 105 are located in Canada and the remainder are in other locations including Chile, Mexico, the United Kingdom, Singapore, China, and Australia. Approximately 26% of our branches are owned facilities, and the remainder are leased.

The following table summarizes our distribution centers:

	Square Feet	Leased/Owned
Location
Warrendale, PA	194,000	Owned
Sparks, NV	131,000	Leased
Byhalia, MS	148,000	Owned
Little Rock, AR	100,000	Leased
Madison, WI	136,000	Leased
Montreal, QC	126,000	Leased
Burnaby, BC	65,000	Owned
Edmonton, AB	101,000	Leased
Mississauga, ON	246,000	Leased

We also lease our 69,000 square-foot headquarters in Pittsburgh, Pennsylvania. We do not regard the real property associated with any single branch location as material to our operations. We believe our facilities are in good operating condition and are adequate for their respective uses.

Item 3. 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. However, management does not believe, based on information presently available, that the ultimate outcome of any such pending matters is likely to have a material adverse effect on our financial condition or liquidity, although the resolution in any quarter of one or more of these matters may have a material adverse effect on our results of operations for that period.

As initially reported in our 2008 Annual Report on Form 10-K, WESCO is a defendant in a lawsuit filed in a state court in Indiana in which a customer, ArcelorMittal Indiana Harbor, Inc. (“AIH”), alleges that the Company sold defective products to AIH in 2004 that were supplied to the Company by others. The lawsuit sought monetary damages in the amount of approximately $50 million. On February 14, 2013, the jury returned a verdict in favor of AIH and awarded damages in the

14

amount of approximately $36.1 million, and judgment was entered on the jury's verdict. As a result, the Company recorded a $36.1 million charge to selling, general and administrative expenses in 2012. The Company disputes this outcome and filed a post-trial motion challenging the verdict alleging various errors that occurred during trial. The Company received letters from its insurers confirming insurance coverage of the matter and recorded a receivable in the quarter ended March 31, 2013 in an amount equal to the previously recorded liability. AIH also filed a post-trial motion asking the court to award additional amounts to AIH, including prejudgment and post-judgment interest. The Court denied the Company's post-trial motion on June 28, 2013 and granted in part AIH's motion, awarding prejudgment interest in the amount of $3.9 million and ordering post-judgment interest to accrue on the entire judgment at 8% per annum. In the quarter ended June 30, 2013, the Company received letters from its insurers confirming insurance coverage of all prejudgment and post-judgment interest related to the matter, and recorded a liability and a corresponding receivable in the amount of $4.7 million for all interest accrued in connection with this matter. Final judgment was entered by the court on July 16, 2013, and the Company is appealing the judgment. The Company has recorded an additional liability and a corresponding receivable in the amount of $1.6 million for post-judgment interest accrued in connection with this matter in the second half of 2013. The judgment may increase or decrease based on the outcome of the appellate proceedings that cannot be predicted with certainty.

Information relating to legal proceedings is included in Note 13, Commitments and Contingencies of the Notes to Consolidated Financial Statements and is incorporated herein by reference.

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.

Market, Stockholder and Dividend Information. Our common stock is listed on the New York Stock Exchange under the symbol “WCC.” As of February 20, 2014, there were 44,383,594 shares of common stock outstanding held by approximately 21 holders of record. We have not paid dividends on the common stock and do not currently plan to pay dividends.  We do, however, evaluate the possibility from time to time. It is currently expected that earnings will be reinvested to support business growth, debt reduction or acquisitions. In addition, our Revolving Credit Facility and Term Loan Agreement restrict our ability to pay dividends. See Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources.” The following table sets forth the high and low sales prices per share of our common stock, as reported on the New York Stock Exchange, for the periods indicated.

Item 7. 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 and notes thereto included in Item 8 of this Annual Report onForm 10-K.

Company Overview

In 2013, we strengthened our organization and talent base, made improvements to our operations and capital structure, expanded our international presence, improved productivity, and integrated four accretive acquisitions into our operations. Sales increased $934.0 million, or 14.2%, over the prior year. Acquisitions positively impacted consolidated sales by 14.6%, organic sales were flat, and foreign currency exchange negatively impacted sales by 0.4%. Cost of goods sold as a percentage of net sales was 79.4% and 79.8% in 2013 and 2012, respectively. Operating income of $481.0 million increased over the prior year primarily due to the integration of EECOL's operations in 2013, and due to the $36.1 million 2013 ArcelorMittal litigation recovery and related fourth quarter 2012 charge of the same amount. Net income attributable to WESCO International, Inc. increased 37.0% over the prior year to $276.4 million. Diluted earnings per share attributable to WESCO International, Inc. were $5.25 in 2013, compared with $3.95 in 2012.

Our end markets consist of industrial firms, electrical and data communications contractors, utilities, and commercial organizations, institutions and governmental entities. Our transaction types to these markets can be categorized as stock, direct ship and special order. Stock orders are filled directly from existing inventory and represented approximately 50% and 45% of total sales for 2013 and 2012, respectively. Approximately 39% and 42% of our total sales were direct ship sales for 2013 and 2012, respectively. Direct ship sales are typically custom-built products, large orders or products that are too bulky to be easily handled and, as a result, are shipped directly to the customer from the supplier. Special orders are for products that are not ordinarily stocked in inventory and are ordered based on a customer’s specific request. Special orders represent the remainder of total sales.

We have historically financed our working capital requirements, capital expenditures, acquisitions, share repurchases and new branch openings through internally generated cash flow, debt issuances, borrowings under our credit facilities and funding through our Receivables Facility.

Cash Flow

We generated $315.1 million in operating cash flow during 2013. Cash provided by operating activities included net income of $276.5 million and adjustments to net income totaling $122.1 million. Cash used in investing activities consisted primarily of purchases of capital assets totaling $27.8 million, partially offset by proceeds of $10.8 million from the sale of assets. Financing activities during 2013 consisted of borrowings and repayments of $833.5 million and $1,026.7 million, respectively, related to our Revolving Credit Facility, borrowings and repayments of $96.5 million and $87.9 million, respectively, related to our Receivables Facility, repayments of $541.2 million related to our Term Loans, borrowings of $500.0 million related to our recently issued senior notes due 2021, and repayments of $26.4 million which extinguished our mortgage financing facility. Financing activities in 2013 also included borrowings and repayments on our various international lines of credit of $72.9 million and $56.5 million, respectively.

Free cash flow for the years ended December 31, 2013 and 2012 was $308.4 million and $265.1 million, respectively.

The following table sets forth the components of free cash flow:

	Twelve Months Ended
	December 31,
Free Cash Flow:	2013			2012
(In millions)
Cash flow provided by operations	$	315.1		$	288.2
Less: Capital expenditures	(27.8		)	(23.1		)
Add: Non-recurring pension contribution	21.1			—
Free cash flow	$	308.4		$	265.1

Note: Free cash flow is non-GAAP financial measure provided by the Company as an additional indicator of liquidity. Capital expenditures are deducted from operating cash flow to determine free cash flow. Free cash flow is available to provide a source of funds for any of the Company's financing needs. During the quarter ended September 30, 2013, a non-recurring contribution was made to fund the Canadian EECOL pension plan. This contribution was required pursuant to the terms of the share purchase agreement by which the Company acquired EECOL in 2012. EECOL sellers fully funded this contribution by way of a direct reduction in the purchase price at the date of acquisition.

18

U.S. GAAP requires the contribution to be shown as a reduction of operating cash flow, however, it is added back to accurately reflect free cash flow.

Financing Availability

As of December 31, 2013, the Company had $605.6 million in total liquidity. Available borrowing capacity under our Revolving Credit Facility, which has a maturity date in August 2016, was $512.2 million, of which $265.7 million was the U.S. sub-facility borrowing limit and $246.5 million was the Canadian sub-facility borrowing limit. The remaining liquidity was provided by invested cash of $93.4 million. At any time on or after September 15, 2016, the Company may redeem all or a part of the 2029 Debentures plus accrued and unpaid interest. For further discussion related to the Debentures, refer to Note 7 of our Notes to the Consolidated Financial Statements. We monitor the depository institutions that hold our cash and cash equivalents on a regular basis, and we believe that we have placed our deposits with creditworthy financial institutions. For further discussions refer to “Liquidity and Capital Resources.”

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. 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 our sales are predominantly 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. In all cases, revenue is recognized once the sales price to our customer is fixed or is determinable and we have reasonable assurance as to the collectability.

In certain customer arrangements, we provide services such as inventory management. We may perform some or all of the following services for customers: determine inventory stocking levels; establish inventory reorder points; launch purchase orders; receive material; put away material; and pick material for order fulfillment. We recognize revenue for services rendered during the period based upon a previously negotiated fee arrangement. We also sell inventory to these customers and recognize revenue at the time title and risk of loss transfers to the customer.

Selling, General and Administrative Expenses

We include warehousing, purchasing, branch operations, information services, and marketing and selling expenses in this category, as well as other types of general and administrative costs.

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.

Excess and Obsolete Inventory

We write down our inventory to its net realizable value based on internal factors derived from historical analysis of actual losses. We identify items at risk of becoming obsolete, which are defined as excess of 36 months supply relative to demand or movement. We then analyze the ultimate disposition of previously identified excess inventory items, such as sold, returned to supplier, or scrapped. This item by item analysis allows us to develop an estimate of the likelihood that an item identified as being in excess supply ultimately becomes obsolete. We apply the estimate to inventory items currently in excess of 36 months supply, and reduce our inventory carrying value by the derived amount. We revisit and test our assumptions on a periodic basis. Historically, we have not had material changes to our assumptions and do not anticipate any material changes in the future.

19

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 us from suppliers. Supplier volume rebate rates have historically ranged between approximately 0.8% and 1.4% of sales depending on market conditions. In 2013, the rebate rate was 1.4%.

Goodwill and Indefinite Life Intangible Assets

We test goodwill and indefinite life intangible assets for impairment annually during the fourth quarter using information available at the end of September, or more frequently when events or circumstances occur indicating that their carrying value may not be recoverable. We test for goodwill impairment on a reporting unit level. The evaluation of impairment involves comparing the current fair value of goodwill and indefinite life intangible assets to the recorded value. We estimate the fair value of goodwill using a combination of discounted cash flow analyses and market multiples. Assumptions used for these fair value techniques are based on a combination of historical results, current forecasts, market data and recent economic events. We evaluate the recoverability of indefinite life intangible assets using a discounted cash flow analysis based on projected financial information. The determination of fair value involves significant management judgment and we apply our best judgment when assessing the reasonableness of financial projections.

A possible indicator of goodwill impairment is the relationship of a company’s market capitalization to its book value. As of December 31, 2013, our market capitalization exceeded our book value and there were no indications of impairment with any of the Company's reporting units.

The reported value of indefinite life trademarks totaled $101.9 million and $105.1 million at December 31, 2013 and 2012, respectively. One trademark valued at $16.6 million is most sensitive to a decline in financial performance. We are taking actions to improve our financial performance related to this business; however, we cannot predict whether or not there will be certain events that could adversely affect the reported value of this trademark.

Intangible Assets

We account for certain economic benefits purchased as a result of our acquisitions, including customer relations, distribution agreements, technology and trademarks, as intangible assets. Most trademarks have an indefinite life. We amortize all other intangible assets over a useful life determined by the expected cash flows produced by such intangibles and their respective tax benefits. Useful lives vary between 4 and 20 years, depending on the specific intangible asset.

Insurance Programs

We use commercial insurance for auto, workers’ compensation, casualty and health claims as a risk sharing strategy to reduce our exposure to 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 account for income taxes using the asset and liability method.  Under this method, deferred tax assets and liabilities result from (i) temporary differences in the recognition of income and expense for financial and income tax reporting requirements, and (ii) differences between the recorded value of assets acquired in business combinations accounted for as purchases for financial reporting purposes and their corresponding tax bases.  Deferred income tax assets are reduced by a valuation allowance if it is more-likely-than-not that some portion of the deferred income tax asset will not be realized.  In evaluating our ability to recover our deferred tax assets, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations.

We recognize the tax benefit from an uncertain tax position only if it is at least more-likely-than-not that the tax position will be sustained upon examination by the taxing authorities based on the technical merits of the position.  The amount of the tax benefit that is recognized is measured as the largest amount of benefit that is more-likely-than-not to be realized upon effective settlement.  We will adjust the tax benefit recognized with regard to an uncertain tax position if our judgment changes as the result of the evaluation of new information not previously available.  Due to the subjectivity inherent in the evaluation of uncertain tax positions, the tax benefit ultimately recognized may materially differ from our estimate.  We recognize interest related to uncertain tax benefits as part of interest expense.  Penalties are recognized as part of income tax expense.

20

Convertible Debentures

We separately account for the liability and equity components of our convertible debentures in a manner that reflects our nonconvertible debt borrowing rate. We estimate our non-convertible debt borrowing rate through a combination of discussions with our financial institutions and review of relevant market data. The discounts to the convertible debenture balances are amortized to interest expense, using the effective interest method, over the implicit life of the debentures.

Stock-Based Compensation

Our stock-based employee compensation plans are comprised of stock options, stock-settled stock appreciation rights, restricted stock units, and performance-based awards. Compensation cost for all stock-based awards is measured at fair value on the date of grant, and compensation cost is recognized, net of estimated forfeitures, over the service period for awards expected to vest. The fair value of stock options and stock-settled appreciation rights is determined using the Black-Scholes valuation model. The performance-based awards are valued based upon a Monte Carlo simulation model. Expected volatilities are based on historical volatility of our common stock. We estimate the expected life of stock options and stock-settled stock appreciation rights using historical data pertaining to option exercises and employee terminations. The risk-free rate is based on the U.S. Treasury yields in effect at the time of grant. The forfeiture assumption is based on our historical employee behavior, which we review on an annual basis. Restricted stock units with vesting dependent upon service conditions are valued based on the market price on the grant date. No dividends are assumed for stock-based awards.

Results of Operations

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

Year Ended December 31,	2013		2012		2011
Net sales	100.0	%	100.0	%	100.0	%
Cost of goods sold	79.4		79.8		79.8

Provision for income taxes	1.4		1.2		1.4
Net income attributable to WESCO International, Inc.	3.7	%	3.1	%	3.2	%

2013 Compared to 2012

Net Sales. Sales in 2013increased 14.2% to $7,513.3 million, compared with $6,579.3 million in 2012. The increase in sales included a positive impact from acquisitions of 14.6% and a negative impact from foreign exchange of 0.4%. Additionally, management estimates a price impact on net sales of approximately 0.2%.

     The following table sets forth normalized organic sales growth:

	Twelve Months Ended
	December 31,
Normalized Organic Sales:	2013		2012
Change in net sales	14.2	%	7.4	%
Less: Impact from acquisitions	14.6	%	3.3	%
Less: Impact from foreign exchange rates	(0.4	)%	(0.3	)%
Less: Impact from number of workdays	—	%	—	%
Normalized organic sales growth	—	%	4.4	%

Note: Normalized organic sales growth is a non-GAAP financial measure provided by the Company to provide a better understanding of the Company's sales growth trends. Normalized organic sales growth is calculated by deducting the percentage impact on net sales from acquisitions, foreign exchange rates and number of workdays from the overall percentage change in consolidated net sales.

21

Cost of Goods Sold. Cost of goods sold increased 13.7% in 2013 to $5,967.9 million, compared with $5,247.9 million in 2012. Cost of goods sold as a percentage of net sales was 79.4% and 79.8% in 2013 and 2012, respectively. The decrease in cost of goods sold percentage was due to the positive margin impact from the Company's EECOL, Conney and Trydor acquisitions.

Selling, General and Administrative (“SG&A”) Expenses. SG&A expenses include costs associated with personnel, shipping and handling, travel, advertising, facilities, utilities and bad debts. SG&A expenses increased by $35.8 million, or 3.7%, to $996.8 million in 2013. The increase in SG&A expenses is primarily due to the EECOL, Conney and Trydor acquisitions. 2013 SG&A expenses include a $36.1 million favorable impact from the recognition of insurance coverage for a litigation-related charge recorded in 2012. Excluding the impact of this item in both periods, SG&A expenses were $1,032.9 million and $924.9 million, or 13.7% and 14.1% of sales, in 2013 and 2012, respectively.

     SG&A payroll expenses for 2013 of $720.2 million increased by $58.6 million compared to 2012. The increase in SG&A payroll expense was primarily due to an increase in salary expense of $71.7 million, partially offset by a decrease in commissions, incentives and benefits of $13.6 million. The increase in payroll expense was primarily due to an increase in headcount, which is the result of the EECOL, Conney and Trydor acquisitions.

     The remaining SG&A expenses for 2013 of $312.7 million increased by $49.4 million compared to 2012, primarily due to increased occupancy and transportation costs of $19.7 million and $13.9 million, respectively, related to recent acquisitions.

Depreciation and Amortization. Depreciation and amortization increased $30.1 million to $67.6 million in 2013, compared with $37.6 million in 2012. The increase in depreciation and amortization was primarily due to the impact from the acquisitions of EECOL, Conney and Trydor in 2012. Amortization of intangible assets of EECOL, Conney and Trydor totaled $26.7 million for 2013.

Income from Operations. Income from operations increased by $148.1 million to $481.0 million in 2013, compared to $332.9 million in 2012.

Interest Expense. Interest expense totaled $85.6 million in 2013, compared with $47.8 million in 2012, an increase of 79.2%. Non-cash interest expense, which includes convertible debt interest, interest related to uncertain tax positions, and the amortization of deferred financing fees, for 2013 and 2012 was $10.2 million and $1.5 million, respectively.

The following table sets forth the components of interest expense:

	Twelve Months Ended
	December 31,
	2013		2012
(In millions)
Amortization of convertible debt	$	4.3	$	2.3
Amortization of deferred financing fees	4.9		2.6
Interest related to uncertain tax provisions	1.0		(3.4		)
Non-Cash Interest Expense	10.2		1.5
Cash Interest Expense	75.4		46.3
	$	85.6	$	47.8

Loss on Debt Extinguishment. In 2013 the Company incurred a loss on debt extinguishment of $13.2 million in connection with the repayment of $500 million of the Company's term loan. In 2012, a loss on debt extinguishment of $3.5 million was incurred due to the redemption of the 2017 Notes.

Loss on Sale of Argentina Business. The Company recorded a loss in 2013 of $2.3 million resulting from the sale and complete divestiture of its EECOL Electric Argentina operations. EECOL Electric Argentina was acquired in 2012 as part of the EECOL Electric acquisition.

Income Taxes. Our effective income tax rate decreased to 27.2% in 2013, compared with 28.4% in 2012, primarily as a result of recording the tax benefit associated with certain foreign tax credits. Our effective tax rate is affected by the relative amounts of income earned in the United States and foreign jurisdictions and the related tax rate differentials on that income.

Net Income. Net income increased by $74.8 million, or 37.1%, to $276.4 million in 2013, compared to $201.8 million in 2012.

Net Income (Loss) attributable to noncontrolling interest. Net income attributable to noncontrolling interest was $0.1 million in 2013. Net loss attributable to noncontrolling interest totaled less than $0.1 million in 2012.

22

Net Income attributable to WESCO International, Inc. Net income and diluted earnings per share attributable to WESCO International, Inc. on a consolidated basis totaled $276.4 million and $5.25 per share, respectively, in 2013, compared with $201.8 million and $3.95 per share, respectively, in 2012.

2012 Compared to 2011

Net Sales. Sales in 2012 increased 7.4% to $6,579.3 million, compared with $6,125.7 million in 2011. Sales were positively impacted by execution of our growth initiatives and recent acquisitions. The increase in sales included a positive impact from acquisitions of 3.3% and a negative impact from foreign exchange of 0.3%. Additionally, management estimates the price impact on net sales was approximately 1.0%.

The following table sets forth normalized organic sales growth:

	Twelve Months Ended
	December 31,
Normalized Organic Sales:	2012		2011
Change in net sales	7.4	%	21.0	%
Less: Impact from acquisitions	3.3	%	6.8	%
Less: Impact from foreign exchange rates	(0.3	)%	0.8	%
Less: Impact from number of workdays	—	%	—	%
Normalized organic sales growth	4.4	%	13.4	%

Cost of Goods Sold. Cost of goods sold increased 7.3% in 2012 to $5,247.9 million, compared with $4,889.1 million in 2011. Cost of goods sold as a percentage of net sales was 79.8% in both 2012 and 2011.

Selling, General and Administrative Expenses. SG&A expenses include costs associated with personnel, shipping and handling, travel, advertising, facilities, utilities and bad debts. SG&A expenses increased by $89.0 million, or 10.2%, to $961.0 million in 2012. The increase in SG&A expenses is primarily due to the $36.1 million 2012 fourth quarter charge related to the ArcelorMittal jury verdict. Additionally, SG&A expenses increased due to the impact from recent acquisitions of $29.7 million and compensation expenses related to the growth in sales. As a percentage of net sales, SG&A expenses increased to 14.6% of sales, compared with 14.2% in 2011.

     SG&A payroll expenses for 2012 of $661.6 million increased by $52.7 million compared to 2011. The increase in SG&A payroll expense was primarily due to an increase in salary expense of $40.8 million and an increase in benefits of $15.5 million. These increases are primarily due to an increase in headcount, which is the result of both recent acquisitions and organic growth initiatives. Temporary labor costs and other SG&A payroll related costs each decreased $2.0 million.

     The remaining SG&A expenses for 2012 of $263.3 million increased by $0.2 million compared to 2011.

Depreciation and Amortization. Depreciation and amortization increased $6.0 million to $37.6 million in 2012, compared with $31.6 million in 2011. The increase in depreciation and amortization was primarily due to the impact from recent acquisitions of $4.6 million.

Income from Operations. Income from operations decreased by $0.1 million to $332.9 million in 2012, compared to $333.0 million in 2011.

Interest Expense. Interest expense totaled $47.8 million in 2012, compared with $53.6 million in 2011, a decrease of 10.9%. Non-cash interest expense, which includes convertible debt interest, interest related to uncertain tax positions, and the amortization of deferred financing fees, for 2012 and 2011 was $1.5 million and $8.8 million, respectively.

Cash Interest Expense	46.3			44.8
	$	47.8		$	53.6

Loss on Debt Extinguishment. In 2012, a loss on debt extinguishment of $3.5 million was incurred due to the redemption of the 2017 Notes.

Income Taxes. Our effective income tax rate decreased to 28.4% in 2012, compared with 29.8% in 2011, primarily as a result of the increase in taxable income outside the United States that is taxed at a lower rate. Our effective tax rate is affected by the relative amounts of income earned in the United States and foreign jurisdictions and the related tax rate differentials on that income.

Net Income. Net income increased by $5.5 million, or 2.8%, to $201.8 million in 2012, compared to $196.2 million in 2011.

Net Loss attributable to noncontrolling interest. Net loss attributable to noncontrolling interest totaled less than $0.1 million in 2012 and 2011.

Net Income attributable to WESCO International, Inc. Net income and diluted earnings per share attributable to WESCO International, Inc. on a consolidated basis totaled $201.8 million and $3.95 per share, respectively, in 2012, compared with $196.3 million and $3.96 per share, respectively, in 2011.

Liquidity and Capital Resources

Total assets were $4.6 billion at December 31, 2013 and 2012. Total liabilities at December 31, 2013 compared to December 31, 2012 decreased by $223.6 million to $2.9 billion. The decrease in total liabilities was primarily due to a decrease in long-term debt of $247.8 million. Stockholders’ equity increased by 13.6% to $1.8 billion at December 31, 2013, compared with $1.6 billion at December 31, 2012, primarily as a result of net earnings of $276.4 million.

Our liquidity needs generally arise from fluctuations in our working capital requirements, capital expenditures, acquisitions and debt service obligations. As of December 31, 2013, we had $512.2 million in available borrowing capacity under our Revolving Credit Facility, which combined with invested cash of $93.4 million provided liquidity of $605.6 million. Invested cash included in our determination of liquidity represents cash deposited in interest bearing accounts. We believe cash provided by operations and financing activities will be adequate to cover our current operational and business needs.

We communicate on a regular basis with our lenders regarding our financial and working capital performance and liquidity position. We are in compliance with all covenants and restrictions contained in our debt agreements as of December 31, 2013.

Our financial leverage ratio as of December 31, 2013 and December 31, 2012 was 3.2 and 4.7, respectively.

The following table sets forth the Company's financial leverage ratio as of December 31, 2013 and December 31, 2012:

Financial leverage ratio based on total debt	3.2			4.7
Financial leverage ratio based on total debt, net of cash	3.0			4.5

Note: Financial leverage is a non-GAAP financial measure provided by the Company as an indicator of capital structure position. Financial leverage ratio based on total debt is calculated by dividing total debt, including debt discount, by Adjusted EBITDA. Financial leverage ratio based on total debt, net of cash, is calculated by dividing total debt, including debt discount, net of cash, by Adjusted EBITDA. Adjusted EBITDA is defined as the trailing twelve months earnings before interest, taxes, depreciation and amortization, excluding the ArcelorMittal litigation charge. Financial leverage ratio based on total net debt is calculated by dividing total debt, including debt discount less cash and cash equivalents, by Adjusted EBITDA.

At December 31, 2013, we had cash and cash equivalents totaling $123.7 million, of which $97.9 million was held by foreign subsidiaries. Included in cash held by foreign subsidiaries is approximately $31.5 million, which was obtained in connection with the acquisition of EECOL on December 14, 2012. This amount is expected to be returned to the sellers in the first half of 2014 and is fully accrued at December 31, 2013. The cash held by some of our foreign subsidiaries could be subject to additional U.S. income taxes if repatriated. We believe that we are able to maintain a sufficient level of liquidity for our domestic operations and commitments without repatriation of the cash held by these foreign subsidiaries.

Over the next several quarters, we expect to maintain working capital productivity, and it is expected that excess cash will be directed primarily at debt reduction and acquisitions. Our near term focus will be managing our working capital as we experience sales growth and maintaining ample liquidity and credit availability. We anticipate capital expenditures in 2014 to be at levels similar to 2013. We believe our balance sheet and ability to generate ample cash flow provides us with a durable business model and should allow us to fund expansion needs and growth initiatives.

We finance our operating and investing needs as follows:

Term Loan Facility

On December 12, 2012, WESCO Distribution, as U.S. borrower, WDCC (WDCC and together with WESCO Distribution, the “Borrowers”), as Canadian borrower, and WESCO International entered into a Term Loan Agreement (the “Term Loan Agreement”) among WESCO Distribution, WDCC, the Company, the lenders party thereto and Credit Suisse AG Cayman Islands Branch, as administrative agent and as collateral agent.

The Term Loan Agreement provided a seven-year term loan facility (the “Term Loan Facility”), which consisted of two separate sub-facilities: (i) a Canadian sub-facility in an aggregate principal amount of CAD $150 million, issued at a 2.0% discount and (ii) a U.S. sub-facility in an aggregate principal amount of US $700 million, issued at a 1.0% discount. The proceeds of the Term Loan Facility were used to finance the acquisition of EECOL, to pay fees and expenses incurred in connection with the acquisition and certain other transactions. Subject to the terms of the Term Loan Agreement, the Borrowers may request incremental term loans from time to time in an aggregate principal amount not to exceed at any time US $300 million, with an equivalent principal amount in U.S. Dollars being calculated for any incremental term loan denominated in Canadian Dollars.

On November 19, 2013, the Borrowers and WESCO International entered into an amendment (the “Term Loan Amendment”) to the Term Loan Agreement. The Term Loan Amendment, among other things, reduced the applicable margin on U.S. term loans by 0.50% and the LIBOR floor applicable to the U.S. sub-facility from 1.00% to 0.75%. The modified pricing terms were effective December 13, 2013.

On November 26, 2013, WESCO Distribution sold $500 million aggregate principal amount of 5.375% Senior Notes due 2021 (the “2021 Notes”), and used the net proceeds plus excess cash to prepay $500 million under the Company's U.S. sub-facility of the Term Loan Facility (see discussion below under “5.375% Senior Notes due 2021” for additional information). The prepayment satisfied all remaining quarterly repayment obligations under the U.S. sub-facility. As a result, the Company recorded a non-cash pre-tax loss on debt extinguishment of $13.2 million in the fourth quarter of 2013. WESCO will amortize the remaining debt discount and financing costs over the life of the instrument. Non-cash interest expense of $2.2 million and $0.1 million was recorded for the years ended December 31, 2013 and 2012, respectively.

Borrowings under the Term Loan Facility bear interest at base rates plus applicable margins. At December 31, 2013, the interest rates on borrowings under the Canadian sub-facility and U.S. sub-facility were approximately 5.3% and 3.75%, respectively. At December 31, 2012, the interest rates on borrowings under the Canadian sub-facility and U.S. sub-facility were approximately 5.2% and 4.5%, respectively. The Canadian Borrower will pay quarterly installments of principal equal to 0.25% of the original principal amount of its term loan sub-facility, plus accrued and unpaid interest. To the extent not previously paid, the term loans will become due and payable on December 12, 2019, with any unpaid incremental term loans becoming due and payable on the respective maturity dates applicable to those incremental term loans. Other than in certain circumstances prior to June 13, 2014, at any time or from time to time, the Borrowers may prepay borrowings under the Term Loan Facility in whole or in part without premium or penalty. The Borrowers' obligations under the Term Loan Facility are secured by substantially all of the assets of the Borrowers, the Company and certain of the Company's other subsidiaries; provided that, with respect to borrowings under the U.S. sub-facility, the collateral does not include assets of certain foreign subsidiaries or more than 65% of the issued and outstanding equity interests in certain foreign subsidiaries.

The Term Loan Facility contains customary affirmative and negative covenants for credit facilities of this type. The Term Loan Facility also provides for customary events of default.

5.375% Senior Notes due 2021

In November 2013, WESCO Distribution issued $500 million aggregate principal amount of 2021 Notes through a private offering exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). The 2021 Notes were issued at 100% of par and are governed by an indenture (the “Indenture”) entered into on November 26, 2013 with WESCO International and U.S. Bank National Association, as trustee. The 2021 Notes are unsecured senior obligations of WESCO Distribution and are guaranteed on a senior unsecured basis by WESCO International. The 2021 Notes bear interest at a stated rate of 5.375%, payable semi-annually in arrears on June 15 and December 15 of each year, with the first interest payment occurring on June 15, 2014. In addition, WESCO recorded deferred financing fees related to the issuance of the 2021 Notes totaling $8.2 million which will be amortized over the life of the notes. The 2021 Notes mature on December 15, 2021. The net proceeds of the 2021 Notes were used to prepay a portion of the U.S. Term Loan sub-facility.

At any time on or after December 15, 2016, WESCO Distribution may redeem all or a part of the 2021 Notes. On and after December 15, 2019, WESCO Distribution may redeem all or a part of the 2021 Notes at a redemption price equal to 100% of the principal amount.

The Indenture governing the 2021 Notes contains customary covenants and customary events of default. In addition, upon a change of control, the holders of 2021 Notes have the right to require WESCO Distribution to repurchase all or any part of the 2021 Notes at a redemption price equal to 101% of the principal amount, plus accrued and unpaid interest.

Mortgage Financing Facility

In 2003, WESCO finalized a mortgage financing facility of $51 million. This facility was extinguished with repayments of $26.4 million in the first quarter of 2013. The interest rate on borrowings under this facility was fixed at 6.5%.

Accounts Receivable Securitization Facility

On September 20, 2013, WESCO Distribution and its subsidiary WESCO Receivables Corp. entered into an amendment (the “Amendment”) of the Third Amended and Restated Receivables Purchase Agreement (the “Receivables Facility”). The Amendment increased the purchase limit under the Receivables Facility from $475 million to $500 million, with the opportunity to exercise an accordion feature which permits increases in the purchase limit of up to an additional $100 million, extended the term of the Receivables Facility to September 20, 2016, and added and amended certain defined terms. The Amendment also reduced the interest rate spread and commitment fee from 1.10% to 0.95% and from 0.55% to 0.45%, respectively. Substantially all other provisions of the Receivables Facility remained unchanged.

Under the Receivables Facility, WESCO sells, on a continuous basis, an undivided interest in all domestic accounts receivable to WESCO Receivables Corp., a wholly owned special purpose entity (the “SPE”). The SPE sells, without recourse, a senior undivided interest in the receivables to financial institutions for cash while maintaining a subordinated undivided interest in the receivables, in the form of overcollateralization. WESCO has agreed to continue servicing the sold receivables for the third-party conduits and financial institutions at market rates; accordingly, no servicing asset or liability has been recorded.

As of December 31, 2013 and 2012, accounts receivable eligible for securitization totaled approximately $586.4 million and $601.1 million, respectively. The consolidated balance sheets as of December 31, 2013 and 2012 include $453.6 million and $445.0 million, respectively, of account receivable balances legally sold to third parties, as well as borrowings for equal amounts. At December 31, 2013 and 2012, the interest rate on borrowings under this facility was approximately 1.2% and 1.4%, respectively.

Revolving Credit Facility

The revolving credit facility (the “Revolving Credit Facility”) was entered into pursuant to the terms and conditions of an Amended and Restated Credit Agreement, dated as of December 12, 2012 (the “Credit Agreement”), among WESCO Distribution, the other US Borrowers party thereto, WESCO Distribution Canada LP (“WESCO Canada”) and WDCC, as Canadian Borrowers, the other Loan Parties party thereto, the Lenders party thereto, JPMorgan Chase Bank, N.A., as Administrative Agent, and JPMorgan Chase Bank, N.A., Toronto Branch, as Canadian Administrative Agent. Subsequent to the acquisition of EECOL on December 14, 2012, EECOL was added as a Canadian Borrower. On November 19, 2013, WESCO Distribution and certain other subsidiaries of the Company entered into a First Amendment to Amended and Restated Credit Agreement and Waiver (the “First Amendment”). The First Amendment, among other things, revised certain covenants and financial statement covenant calculations in the Credit Agreement. The Revolving Credit Facility contains an accordion feature allowing WESCO Distribution to request increases to the borrowing commitments under the Credit Facility of up to US $100 million in the aggregate.

The Revolving Credit Facility matures in August 2016 and consists of two separate sub-facilities: (i) a Canadian sub-facility with a borrowing limit of up to US $400 million, which is collateralized by substantially all assets of WESCO Canada, WDCC

27

and EECOL, and (ii) a U.S. sub-facility with a borrowing limit of up to US $600 million less the amount of outstanding borrowings under the Canadian sub-facility. The U.S. sub-facility is collateralized by substantially all assets of WESCO Distribution and its U.S. subsidiaries other than real property and accounts receivable sold or intended to be sold pursuant to the Receivables Facility. Availability under the Revolving Credit Facility is based upon the amount of eligible inventory and receivables applied against certain advance rates. The applicable interest rate for borrowings under the Revolving Credit Facility includes interest rate spreads based on available borrowing capacity that range between 1.50% and 2.00% for LIBOR and CDOR-based borrowings and 0.50% and 1.00% for prime rate-based borrowings. The otherwise applicable interest rate is reduced by 0.25% if the Company's leverage ratio falls below a ratio of 2.5 to 1.0. At December 31, 2013, the interest rate on borrowings under this facility was approximately 3.5%.

The Credit Agreement contains customary affirmative and negative covenants for credit facilities of this type. Subject to the terms of the Credit Agreement, the Company is permitted to pay dividends, repurchase common stock or repurchase indebtedness without limitation so long as pro forma combined availability under the Revolving Credit Facility and the Receivables Facility exceeds US $163.8 million and the adjusted fixed charge ratio is not less than a ratio of 1.1 to 1.0.

During 2013, WESCO borrowed $833.5 million in the aggregate under the Revolving Credit Facility and made repayments in the aggregate amount of $1,026.7 million. During 2012, aggregate borrowings and repayments were $814.1 million and $632.9 million, respectively. WESCO had $512.2 million available under the Revolving Credit facility at December 31, 2013, after giving effect to outstanding letters and international lines of credit, as compared to approximately $270.9 million at December 31, 2012.

7.50% Senior Subordinated Notes due 2017

On December 10, 2012, WESCO International announced that WESCO Distribution would redeem all of its outstanding 2017 Notes on January 9, 2013 (the “Redemption Date”) at a redemption price equal to 101.25% of the principal amount thereof plus accrued and unpaid interest to, but excluding, the Redemption Date, for a total of $1,030 per $1,000 principal amount of 2017 Notes. The aggregate principal amount of 2017 Notes outstanding was $150.0 million. On December 11, 2012, in accordance with the terms of the Indenture, dated as of September 27, 2005, among WESCO Distribution, WESCO International and The Bank of New York Mellon, as trustee (the “Trustee”), WESCO Distribution irrevocably deposited with the Trustee funds sufficient to pay principal and interest of all outstanding 2017 Notes on the Redemption Date. As a result, the Indenture was satisfied and discharged.

International Lines of Credit

Certain foreign subsidiaries of WESCO have entered into uncommitted lines of credit, which serve as overdraft facilities, to support local operations. The maximum borrowing limit varies by facility and ranges between US $1.0 million and US $15.0 million. The applicable interest rate for borrowings under these lines of credit varies by country and is governed by the applicable loan agreement. The international lines of credit are renewable on an annual basis and certain facilities are fully and unconditionally guaranteed by WESCO Distribution. Accordingly, these lines directly reduce availability under the Revolving Credit Facility.

1.75% Convertible Senior Debentures due 2026

Proceeds of $300 million were received in connection with the issuance of the 2026 Debentures by WESCO International in November 2006. On August 27, 2009, WESCO International completed an exchange offer pursuant to which it issued $345 million in aggregate principal amount of 2029 Debentures in exchange for approximately $299.7 million and $57.7 million in aggregate principal amounts of its outstanding 2026 Debentures and 2025 Debentures, respectively (see the 6.0% Convertible Senior Debentures due 2029 discussion below for additional information). On November 30, 2011, WESCO International announced that it would redeem all of its 2026 Debentures on January 3, 2012. WESCO International redeemed the remaining $0.1 million aggregate principal amount of outstanding 2026 Debentures at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest. Following the redemption on January 3, 2012, there were no 2026 Debentures outstanding.

6.0% Convertible Senior Debentures due 2029

On August 27, 2009, WESCO International completed an exchange offer pursuant to which it issued $345 million in aggregate principal amount of 2029 Debentures in exchange for approximately $299.7 million and $57.7 million in aggregate principal amounts of its outstanding 2026 Debentures and 2025 Debentures, respectively. As a result of the debt exchange, WESCO recorded a gain of $6.0 million, which included the write-off of debt issuance costs. The 2029 Debentures were issued pursuant to an Indenture dated August 27, 2009 (the “Indenture”), with The Bank of New York Mellon, as trustee, and are unconditionally guaranteed on an unsecured senior subordinate basis by WESCO Distribution.

28

WESCO utilized an interest rate of 13.875% to reflect the non-convertible debt borrowing rate of its offering upon issuance, which was determined based on discussions with its financial institutions and a review of relevant market data, and resulted in a $181.2 million discount to the 2029 Debenture balance and a net increase in additional capital of $106.5 million. In addition, the financing costs related to the issuance of the 2029 Debentures were allocated between the debt and equity components. WESCO is amortizing the debt discount and financing costs over the life of the instrument. Non-cash interest expense of $10.2 million and $1.5 million was recorded for the years ended December 31, 2013 and 2012, respectively. The debt discount amortization will approximate $3.4 million in 2014, $3.9 million in 2015, $4.5 million in 2016, $5.1 million in 2017, and $5.8 million in 2018.

While the 2029 Debentures accrue interest at an effective interest rate of 13.875% (as described above), the coupon interest rate of 6.0% per annum is payable in cash semi-annually in arrears on each March 15 and September 15. Beginning with the six-month period commencing September 15, 2016, WESCO International will also pay contingent interest during any six-month period in which the trading price of the 2029 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 2029 Debentures. During any six-month period when contingent interest shall be payable, the contingent interest payable per $1,000 principal amount of 2029 Debentures will equal 0.25% of the average trading price of $1,000 principal amount of the 2029 Debentures during the five trading days ending on the second trading day immediately preceding the first day of the applicable six-month interest period. In accordance with guidance related to derivatives and hedging, the contingent interest feature of the 2029 Debentures is an embedded derivative that is not considered clearly and closely related to the host contract. The contingent interest component had no significant value at December 31, 2013 or 2012.

The 2029 Debentures are convertible into cash, and in certain circumstances, shares of WESCO International's common stock, $0.01 par value, at any time on or after September 15, 2028, or prior to September 15, 2028 in certain circumstances. The 2029 Debentures will be convertible based on an initial conversion rate of 34.6433 shares of common stock per $1,000 principal amount of the 2029 Debentures (equivalent to an initial conversion price of approximately $28.87 per share). The conversion rate and conversion price may be adjusted under certain circumstances.

At any time on or after September 15, 2016, the Company may redeem all or a part of the 2029 Debentures plus accrued and unpaid interest (including contingent interest and additional interest, if any) to, but not including, the redemption date. If WESCO International undergoes certain fundamental changes, as defined in the Indenture, prior to maturity, holders of the 2029 Debentures will have the right, at their option, to require WESCO International to repurchase for cash some or all of their 2029 Debentures at a repurchase price equal to 100% of the principal amount of the 2029 Debentures being repurchased, plus accrued and unpaid interest (including contingent interest and additional interest, if any) to, but not including, the repurchase date.

The following table sets forth the components of WESCO's outstanding convertible debenture indebtedness:

	December 31, 2013				December 31, 2012
	Principal Balance	Discount		Net Carrying Amount	Principal Balance	Discount		Net Carrying Amount
(In thousands)
2029 Convertible Debentures	344,901	(170,752	)	174,149	344,921	(173,708	)	171,213

Covenant Compliance

We were in compliance with all relevant covenants contained in our debt agreements as of December 31, 2013.

Primary uses of cash in 2012 included $29.3 million for the increase in inventory, $24.3 million for the decrease in payables and $21.8 million for the increase in other accounts receivable.

29

Investing Activities. Net cash used by investing activities in 2013 was $18.2 million, compared with $1,311.0 million of net cash used in 2012. Capital expenditures were $27.8 million and $23.1 million in 2013 and 2012, respectively. Proceeds from the sale of assets were $10.8 million and $1.6 million in 2013 and 2012, respectively. During 2012, payments of $1,289.5 million were made for the acquisition of the businesses of EECOL, RS, Trydor and Conney.

Financing Activities. Net cash used by financing activities in 2013 was $257.5 million, compared with $1,044.0 million of net cash provided in 2012. During 2013 financing activities consisted of borrowings and repayments of $833.5 million and $1,026.7 million, respectively, related to our Revolving Credit Facility, borrowings and repayments of $96.5 million and $87.9 million, respectively, related to our Receivables Facility, repayments of $541.2 million related to our Term Loan Facility, borrowings of $500.0 million related to our recently issued 2021 Notes, and repayments of $26.4 million which extinguished our mortgage financing facility. Financing activities in 2013 also included borrowings and repayments on our various international lines of credit of $72.9 million and $58.3 million, respectively. During 2012, financing activities consisted of borrowings and repayments of $787.0 million and $605.7 million, respectively, related to our Revolving Credit Facility, borrowings and repayments of $672.1 million and $477.1 million, respectively, related to our Receivables Facility, borrowings of $840.8 related to the Term Loan Facility, and repayments of $150.0 related to early redemption of all the outstanding 2017 Notes.

Contractual Cash Obligations and Other Commercial Commitments

The following summarizes our contractual obligations, including interest, at December 31, 2013 and the effect such obligations are expected to have on liquidity and cash flow in future periods.

	2014		2015 to 2016		2017 to 2018		2019 - After		Total
(In millions)
Contractual cash obligations (including interest):
Debt, excluding debt discount	$	40.1	$	480.5	$	3.6	$	1,138.3	$	1,662.5
Interest on indebtedness(1)	68.4		131.7		121.7		313.3		635.1
Non-cancelable operating leases	55.9		92.2		60.9		63.7		272.7
Total contractual cash obligations	$	164.4	$	704.4	$	186.2	$	1,515.3	$	2,570.3

⁽¹⁾  Interest on the variable rate debt was calculated using the rates and balances outstanding at December 31, 2013.

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. Also, we do not consider obligations to taxing authorities for uncertain tax benefits to be contractual obligations requiring disclosure due to the uncertainty surrounding the ultimate settlement and timing of these obligations. As such, we have not included $34.1 million of such estimated liability in the table above.

Inflation

The rate of inflation, as measured by changes in the producer price index, affects different commodities, the cost of products purchased and ultimately the pricing of our different products and product classes to our customers. Our pricing related to inflation did not have a material impact on our sales revenue for the year ended December 31, 2013. Historically, price changes from suppliers have been consistent with inflation and have not had a material impact on the results of operations.

Seasonality

Our operating results are not significantly affected by seasonal factors. Sales during the first quarter are affected by a reduced level of activity. Sales during the second, third and fourth quarters are generally 4-6% higher than the first quarter. Sales typically increase beginning in March, with slight fluctuations per month through October. During periods of economic expansion or contraction our sales by quarter have varied significantly from this pattern.

Item 7A. Quantitative and Qualitative Disclosures about Market Risks.

Foreign Currency Risks

Approximately 70% 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, South America, Europe, Africa, Asia and Australia and may establish additional foreign subsidiaries in the future. Accordingly, we may derive a larger 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

Fixed Rate Borrowings: Approximately 51% of our debt portfolio is comprised of fixed rate debt. At various times, we have refinanced our debt to mitigate the impact of interest rate fluctuations. As the 2021 Notes and 2029 Debentures were issued at fixed rates, interest expense would not be impacted by interest rate fluctuations, although market value would be. The aggregate fair value of the 2021 Notes and 2029 Debentures was $505.6 million and $1,124.3 million, respectively, at December 31, 2013. Interest expense on our other fixed rate debt also would not be impacted by changes in market interest rates. For this fixed rate debt, fair value approximated carrying value at December 31, 2013 (see Note 7 to the Consolidated Financial Statements).

Floating Rate Borrowings: The Company's variable rate borrowings at December 31, 2013 were comprised of the amounts outstanding under the Term Loan Facility, Receivables Facility and Revolving Credit Facility. The fair value of these debt instruments at December 31, 2013 approximated carrying value, which totaled $776.4 million. We entered into the Term Loan Facility on December 12, 2012 and the proceeds were primarily used to finance the acquisition of EECOL. Borrowings under the U.S. and Canadian sub-facilities of the Term Loan Facility bear interest at 0.75% and 1.0%, respectively, or, if greater, the applicable LIBOR (London Interbank Offered Rate) / CDOR (Canadian Dealer Offered Rate) or base rates plus applicable margins and therefore are subject to fluctuations in interest rates. We borrow under our Revolving Credit Facility and Receivables Facility for general corporate purposes, including working capital requirements and capital expenditures. Borrowings under our Revolving Credit Facility bear interest at base rates plus applicable margins, whereas, borrowings under the Receivables Facility bear interest at the 30 day LIBOR plus applicable margins. A 100 basis point increase or decrease in interest rates would not have a significant impact on future earnings under our current capital structure.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of WESCO International, Inc.:

In our opinion, the consolidated balance sheets and the related consolidated statements of comprehensive income, stockholders’ equity and cash flows present fairly, in all material respects, the financial position of WESCO International, Inc. and its subsidiaries at December 31, 2013 and 2012, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2013 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the indexappearing under Item 15 (a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control - Integrated Framework(1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION

WESCO International, Inc. ("WESCO International") and its subsidiaries (collectively, “WESCO”), headquartered in Pittsburgh, Pennsylvania, is a full-line distributor of electrical, industrial and communications maintenance, repair and operating (“MRO”) and original equipment manufactures (“OEM”) products, construction materials, and advanced supply chain management and logistics services used primarily in the industrial, construction, utility and commercial, institutional and government markets. We serve over 75,000 active customers globally, through approximately 475 full service branches and nine distribution centers located primarily in the United States, Canada and Mexico, with operations in 15 additional countries.

2. ACCOUNTING POLICIES

Basis of Consolidation

The consolidated financial statements include the accounts of WESCO International and all of its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. Although these estimates are based on management’s best knowledge of current events and actions WESCO may undertake in the future, actual results may ultimately differ from the estimates.

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. In the case of stock sales and special orders, a sale occurs at the time of shipment from WESCO's distribution point, as the terms of WESCO’s sales are typically FOB shipping point. In cases where WESCO processes customer orders but ships directly from its suppliers, revenue is recognized once product is shipped and title has passed. In all cases, revenue is recognized once the sales price to the customer is fixed or is determinable and WESCO has reasonable assurance as to the collectability.

In certain customer arrangements, WESCO provides services such as inventory management. WESCO may perform some or all of the following services for customers: determine inventory stocking levels; establish inventory reorder points; launch purchase orders; receive material; put away material; and pick material for order fulfillment. WESCO recognizes revenue for services rendered during the period based upon a previously negotiated fee arrangement. WESCO also sells inventory to these customers and recognizes revenue at the time title and risk of loss transfers to the customer. The amount of revenue attributed to these services totaled $24.2 million, $17.6 million, and $10.8 million in 2013, 2012 and 2011, respectively.

Selling, General and Administrative Expenses

WESCO includes warehousing, purchasing, branch operations, information services, and marketing and selling expenses in this category, as well as other types of general and administrative costs.

Supplier Volume Rebates

WESCO receives volume rebates from certain suppliers based on contractual arrangements with such suppliers. Volume rebates are included within other accounts receivable on the balance sheet, and represent the estimated amounts due to WESCO under the rebate provisions of the various supplier contracts. 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. Receivables under the supplier rebate program were $75.0 million at December 31, 2013 and $68.7 million at December 31, 2012. Supplier volume rebate rates have historically ranged between approximately 0.8% and 1.4% of sales depending on market conditions. In 2013, the rebate rate was 1.4%.

Shipping and Handling Costs and Fees

WESCO records the costs and fees associated with transporting its products to customers as a component of selling, general and administrative expenses. These costs totaled $63.8 million, $49.9 million and $50.9 million in 2013, 2012 and 2011, respectively.

Cash Equivalents

Cash equivalents are defined as highly liquid investments with original maturities of 90 days or less when purchased.

38

Asset Securitization

WESCO maintains control of the receivables transferred pursuant to its accounts receivable securitization program (the “Receivables Facility”); therefore the transfers do not qualify for “sale” treatment. As a result, the transferred receivables remain on the balance sheet, and WESCO recognizes the related secured borrowing. The expenses associated with the Receivables Facility are reported as interest expense in the statement of income.

Allowance for Doubtful Accounts

WESCO maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. WESCO has a systematic procedure using estimates based on historical data and reasonable assumptions of collectability made at the local branch level and on a consolidated corporate basis to calculate the allowance for doubtful accounts. If the financial condition of WESCO’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The allowance for doubtful accounts was $19.3 million at December 31, 2013 and $17.2 million at December 31, 2012. The total amount recorded as selling, general and administrative expense related to bad debts was $2.9 million, $1.1 million and $6.6 million for 2013, 2012 and 2011, respectively.

Inventories

Inventories primarily consist of merchandise purchased for resale and are stated at the lower of cost or market. Cost is determined principally under the average cost method. WESCO makes provisions for obsolete or slow-moving inventories as necessary to reflect reduction in inventory value. WESCO writes down its inventory to its net realizable value based on internal factors derived from historical analysis of actual losses. Retrospectively, WESCO identifies items at risk of becoming obsolete, which are defined as excess of 36 months supply relative to demand or movement. WESCO then analyzes the ultimate disposition of previously identified excess inventory items, such as sold, returned to supplier, or scrapped. This item by item analysis allows WESCO to develop an estimate of the historical likelihood that an item identified as being in excess supply ultimately becomes obsolete. WESCO applies the estimate to inventory items currently in excess of 36 months supply, and reduces its inventory carrying value by the derived amount. Reserves for excess and obsolete inventories were $17.4 million and $16.7 million at December 31, 2013 and 2012, respectively. The total expense related to excess and obsolete inventories, included in cost of goods sold, was $7.5 million, $11.4 million and $5.5 million for 2013, 2012 and 2011, respectively. WESCO absorbs into the cost of inventory certain overhead expenses related to inventory such as purchasing, receiving and storage and at December 31, 2013 and 2012, $62.1 million and $62.2 million, respectively, of these costs were included in ending inventory.

Other Assets

WESCO amortizes deferred financing fees over the term of the various debt instruments. Deferred financing fees in the amount of $12.2 million were incurred during the year ending December 31, 2013. As of December 31, 2013 and 2012, the amount of other assets related to unamortized deferred financing fees was $24.8 million and $26.4 million, respectively.

Property, Buildings and Equipment

Property, buildings and equipment are recorded at cost. Depreciation expense is determined using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized over either their respective lease terms or their estimated lives, whichever is shorter. Estimated useful lives range from five to forty years for leasehold improvements and buildings and three to ten years for furniture, fixtures and equipment.

Capitalized computer software costs are amortized using the straight-line method over the estimated useful life, typically three to five years, and are reported at the lower of unamortized cost or net realizable value.

Expenditures for new facilities and improvements that extend the useful life of an asset are capitalized. Ordinary repairs and maintenance are expensed as incurred. When property is retired or otherwise disposed of, the cost and the related accumulated depreciation are removed from the accounts and any related gains or losses are recorded and reported as selling, general and administrative expenses.

WESCO assesses its long-lived assets for impairment by periodically reviewing operating performance and respective utilization of real and tangible assets. Upon closure of any branch, asset usefulness and remaining life are evaluated and charges are taken as appropriate. Of WESCO’s $198.7 million net book value of property, plant and equipment as of December 31, 2013, $125.3 million consists of land, buildings and leasehold improvements and are geographically dispersed among WESCO’s 475 branches and nine distribution centers, mitigating the risk of impairment. Approximately $33.3 million of assets consist of computer equipment and capitalized software and are evaluated for use and serviceability relative to carrying value. The remaining fixed assets, mainly furniture and fixtures, warehousing equipment and transportation equipment, are similarly evaluated for serviceability and use.

Goodwill and Indefinite Life Intangible Assets

Goodwill and indefinite life intangible assets are tested for impairment annually during the fourth quarter using information available at the end of September, or more frequently if events or circumstances occur indicating that their carrying value may not be recoverable. The evaluation of impairment involves comparing the current fair value of goodwill and indefinite life intangible assets to the recorded value. WESCO estimates the fair value of goodwill using a combination of discounted cash flow analyses and market multiples. Assumptions used for these fair value techniques are based on a combination of historical results, current forecasts, market data and recent economic events. WESCO evaluates the recoverability of indefinite life intangible assets using a discounted cash flow analysis based on projected financial information. The determination of fair value involves significant judgment and management applies its best judgment when assessing the reasonableness of financial projections. At December 31, 2013 and 2012, goodwill and indefinite life trademarks totaled $1,837.4 million and $1,882.9 million, respectively. No impairment losses were identified in 2013 as a result of this review.

Definite Lived Intangible Assets

Intangible assets are amortized over 4 to 20 years. A portion of intangible assets related to certain customer relationships are amortized using an accelerated method whereas all other intangible assets subject to amortization use a straight-line method which reflects the pattern in which the economic benefits of the respective assets are consumed or otherwise used. Intangible assets are tested for impairment if events or circumstances occur indicating that the respective asset might be impaired.

Insurance Programs

WESCO uses commercial insurance for auto, workers’ compensation, casualty and health claims as a risk-reduction strategy to minimize catastrophic losses. The Company’s strategy involves large deductibles where WESCO must pay all costs up to the deductible amount. WESCO estimates the reserve based on historical incident rates and costs. The assumptions included in developing this accrual include the period of time from incurrence of a claim until the claim is paid by the insurance provider. The total liability related to the insurance programs was $11.4 million at December 31, 2013 and $11.3 million at December 31, 2012.

Income Taxes

WESCO accounts for income taxes using the asset and liability method.  Under this method, deferred tax assets and liabilities result from (i) temporary differences in the recognition of income and expense for financial and income tax reporting requirements, and (ii) differences between the recorded value of assets acquired in business combinations accounted for as purchases for financial reporting purposes and their corresponding tax bases.  Deferred income tax assets are reduced by a valuation allowance if it is more-likely-than-not that some portion of the deferred income tax asset will not be realized.  In evaluating our ability to recover our deferred tax assets, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations.

WESCO recognizes the tax benefit from an uncertain tax position only if it is at least more-likely-than-not that the tax position will be sustained upon examination by the taxing authorities based on the technical merits of the position.  The amount of the tax benefit that is recognized is measured as the largest amount of benefit that is more-likely-than-not to be realized upon effective settlement.  We will adjust the tax benefit recognized with regard to an uncertain tax position if our judgment changes as the result of the evaluation of new information not previously available.  Due to the subjectivity inherent in the evaluation of uncertain tax positions, the tax benefit ultimately recognized may materially differ from our estimate.  WESCO recognizes interest related to uncertain tax benefits as part of interest expense.  Penalties are recognized as part of income tax expense.

Convertible Debentures

WESCO separately accounts for the liability and equity components of its convertible debentures in a manner that reflects its non-convertible debt borrowing rate. WESCO estimates its non-convertible debt borrowing rate through a combination of discussions with its financial institutions and review of relevant market data. The discounts to the convertible note balances are amortized to interest expense, using the effective interest method, over the implicit life of the Debentures.

Foreign Currency

The local currency is the functional currency for the majority of WESCO’s operations outside the United States. Assets and liabilities of these operations are translated to U.S. dollars at the exchange rate in effect at the end of each period. Income statement accounts are translated at the average exchange rate prevailing during the period. Translation adjustments arising from the use of differing exchange rates from period to period are included as a component of other comprehensive income within stockholders’ equity. Gains and losses from foreign currency transactions are included in net income for the period.

Defined Benefit Pension Plan

In connection with the December 14, 2012 acquisition of EECOL, the Company assumed a contributory defined benefit plan covering all Canadian employees of EECOL. The plan provides retirement benefits based upon earnings and credited service, and participants contribute 2% or 4% of their earnings to the plan depending on their employment level.

The Company also assumed EECOL's Supplemental Executive Retirement Plan (SERP) which provides additional pension benefits to certain executives based on earnings, credited service, and executive service.

Liabilities and expenses for pension benefits are determined using actuarial methodologies and incorporate significant assumptions, including the interest rate used to discount the future estimated cash flows, the expected long-term rate of return on plan assets, and several assumptions relating to the employee workforce (salary increases, retirement age, and mortality).

The interest rate used to discount future estimated cash flows is determined using a high quality corporate bonds yield curve model developed with the assistance of an external actuary. The cash flows of the plans' projected benefit obligations are discounted using a single equivalent rate derived from yields on high quality corporate bonds. The yield curve model parallels the plans' projected cash flows. The discount rate used to determine benefit obligations for the Canadian pension was 4.9% in 2013. An increase in the discount rate of one quarter percent would decrease the projected benefit obligation by $4.5 million, and a decrease in the discount rate of one quarter percent would increase the projected benefit obligation by $5.1 million. The impact of a change in the discount rate of one quarter percent would be either a charge or credit of $0.3 million to earnings in the following year.

The expected long-term rate of return on plan assets is applied to the fair market-related value of plan assets.

Stock-Based Compensation

WESCO’s stock-based employee compensation plans are comprised of stock options, stock-settled stock appreciation rights, restricted stock units, and performance-based awards. Compensation cost for all stock-based awards is measured at fair value on the date of grant, and compensation cost is recognized, net of estimated forfeitures, over the service period for awards expected to vest. The fair value of stock options and stock-settled appreciation rights is determined using the Black-Scholes valuation model. Expected volatilities are based on historical volatility of WESCO’s common stock. The expected life of stock options and stock-settled appreciation rights is estimated using historical data pertaining to option exercises and employee terminations. The risk-free rate is based on the U.S. Treasury yields in effect at the time of grant. The forfeiture assumption is based on WESCO’s historical employee behavior that is reviewed on an annual basis. The fair value of restricted stock units is determined by the grant-date closing price of WESCO’s common stock. Performance-based awards are valued using a Monte Carlo simulation model. The probability of meeting market criteria is considered when calculating the estimated fair market value on the date of grant. These awards are accounted for as awards with market conditions, which are recognized over the service period, regardless of whether the market conditions are achieved and the awards ultimately vest. No dividends are assumed for stock based awards.

Treasury Stock

Common stock purchased for treasury is recorded at cost. At the date of subsequent reissue, the treasury stock account is reduced by the cost of such stock, with cost determined on a weighted average basis.

Fair Value of Financial Instruments

The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable and other accrued liabilities, and outstanding indebtedness. The estimated fair value of the Company’s outstanding indebtedness described in Note 7 at December 31, 2013 and 2012 was $2,443.9 million and $2,423.7 million, respectively. The aggregate fair value of the 2021 Notes, Term Loan Facility and debentures was approximately $1,930.2 million and $1,704.5 million at December 31, 2013 and 2012, respectively. The fair values of fixed rate facilities are estimated based upon market price quotes. The fair values of the mortgage facility, the Term Loan Facility, the accounts receivable securitization facility (the "Receivables Facility") and the revolving credit facility ("the Revolving Credit Facility"), approximated carrying values. The fair values for these facilities are based upon market price quotes and market comparisons available for instruments with similar terms and maturities. For all remaining WESCO financial instruments, carrying values are considered to approximate fair value due to their short maturities.

Environmental Expenditures

WESCO has facilities and operations that distribute certain products that must comply with environmental regulations and laws. Expenditures for current operations are expensed or capitalized, as appropriate. Expenditures relating to existing conditions caused by past operations, and that do not contribute to future revenue, are expensed. Liabilities are recorded when remedial efforts are probable and the costs can be reasonably estimated.

Recently Adopted Accounting Pronouncements

In June 2011, the Financial Accounting Standards Board (the "FASB") issued new disclosure guidance related to the presentation of the statement of comprehensive income. This guidance provides an entity the option to present the total of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements; the option to report other comprehensive income and its components in the statement of changes in stockholders' equity was eliminated. This accounting standard is effective for periods beginning on or after December 15, 2011. WESCO has elected the option to present the components of net income and the components of comprehensive income in a single continuous statement of comprehensive income.

In July 2012, the Financial Accounting Standards Board (the "FASB") issued updated guidance on the periodic testing of indefinite-lived intangible assets, other than goodwill, for impairment. This updated guidance allows companies the option to first assess qualitative factors to determine if it is more-likely-than-not that an indefinite-lived intangible asset might be impaired and whether it is necessary to perform the quantitative impairment test required under current accounting standards. This guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. WESCO adopted this guidance in 2013. Adoption of this guidance did not have a material impact on WESCO's financial position, results of operations or cash flows.

In February 2013, the FASB issued updated guidance on the reporting of amounts reclassified from accumulated other comprehensive income. This updated guidance requires entities to present significant amounts reclassified from each component of accumulated other comprehensive income and the income statement line items affected by the reclassification. This guidance is effective for interim and annual periods beginning after December 15, 2012. WESCO adopted this guidance in 2013. Adoption of this guidance did not have a material impact on WESCO's financial position, results of operations or cash flows.

Recently Issued Accounting Pronouncements

In July 2013, the FASB issued updated guidance on the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This updated guidance requires entities to present unrecognized tax benefits, or a portion of unrecognized tax benefits, in the financial statements as a reduction to deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, with certain exceptions. This guidance is effective for interim and annual periods beginning after December 15, 2013. WESCO will adopt this guidance in 2014. Adoption of this guidance is not expected to have a material impact on WESCO's financial position, results of operations or cash flows.

Other pronouncements issued by the FASB or other authoritative accounting standards groups with future effective dates are either not applicable or are not expected to be significant to WESCO’s financial position, results of operations or cash flows.

4. CONCENTRATIONS OF CREDIT RISK AND SIGNIFICANT SUPPLIERS

WESCO distributes its products and services and extends credit to a large number of customers in the industrial, construction, utility, commercial, institutional, and governmental markets. WESCO’s largest supplier accounted for approximately 12% of WESCO's purchases in 2013 and 2012, and 10% of purchases in 2011, and therefore, WESCO could potentially incur risk due to supplier concentration. Based upon WESCO’s broad customer base, the Company has concluded that it has no material credit risk as a result of customer concentration.

Acquisition of EECOL Electric Corporation

On December 14, 2012, WESCO International completed its acquisition of EECOL Electric Corporation (“EECOL”). WESCO paid at closing a cash purchase price of approximately $1.1 billion, of which $50.8 million was placed in escrow to address post-closing purchase price adjustments and potential indemnification claims. The remaining escrow will be distributed to the sellers in the first half of 2014. To fund the purchase price paid at closing, WESCO and its subsidiaries borrowed $851 million under new term loans and $264 million under the Revolving Credit Facility. The Company incurred $4.0 million in acquisition costs related to the EECOL acquisition in 2012. With the acquisition of EECOL, WESCO obtained a 60% ownership in a joint venture. This entity has been consolidated. The noncontrolling interest recognized income of less than $0.1 million in 2013 and 2012.

EECOL is a full-line distributor of electrical equipment, products and services with approximately 57 locations across Canada and approximately 20 in South America. EECOL has a warehouse-based business focused on serving industrial, oil, gas, mining, utility, and commercial and residential construction customers.

The preliminary purchase price was allocated to the respective assets and liabilities based upon their estimated fair values as of the acquisition date. The fair value of the intangible assets was estimated by management and the allocation resulted in intangible assets of $301.7 million and goodwill of $676.1 million which is not deductible for tax purposes. The intangible assets include customer relationships of $246 million amortized over 20 years and trademarks of $55.7 million. Trademarks have an indefinite life and are not being amortized. No residual value is estimated for these intangible assets. The goodwill arising from the acquisition is based largely on the depth and diversity of name brand products, warehouse locations, and a highly-trained and knowledgeable workforce. The purchase price allocation was finalized in 2013. The fair value of assets and liabilities acquired have been retrospectively adjusted for certain measurement period adjustments resulting in an increase to goodwill of $5.7 million, a decrease in all other assets of $0.9 million, and a corresponding increase in liabilities of $4.8 million.

Approximately $31.5 million of the $32.1 million of cash and equivalents that was transferred to the Company is expected to be remitted back to the sellers in the first half of 2014, and accordingly, a corresponding liability has been recorded at December 31, 2013.

Term Loan Facility

On December 12, 2012, WESCO Distribution, as U.S. borrower, WDCC (WDCC and together with WESCO Distribution, the “Borrowers”), as Canadian borrower, and WESCO International entered into a Term Loan Agreement (the “Term Loan Agreement”) among WESCO Distribution, WDCC, the Company, the lenders party thereto and Credit Suisse AG Cayman Islands Branch, as administrative agent and as collateral agent.

The Term Loan Agreement provided a seven-year term loan facility (the “Term Loan Facility”), which consisted of two separate sub-facilities: (i) a Canadian sub-facility in an aggregate principal amount of CAD $150 million, issued at a 2.0% discount and (ii) a U.S. sub-facility in an aggregate principal amount of US $700 million, issued at a 1.0% discount. The proceeds of the Term Loan Facility were used to finance the acquisition of EECOL, to pay fees and expenses incurred in

47

connection with the acquisition and certain other transactions. Subject to the terms of the Term Loan Agreement, the Borrowers may request incremental term loans from time to time in an aggregate principal amount not to exceed at any time US $300 million, with an equivalent principal amount in U.S. Dollars being calculated for any incremental term loan denominated in Canadian Dollars.

On November 19, 2013, the Borrowers and WESCO International entered into an amendment (the “Term Loan Amendment”) to the Term Loan Agreement. The Term Loan Amendment, among other things, reduced the applicable margin on U.S. term loans by 0.50% and the LIBOR floor applicable to the U.S. sub-facility from 1.00% to 0.75%. The modified pricing terms were effective December 13, 2013.

On November 26, 2013, WESCO Distribution sold $500 million aggregate principal amount of 5.375% Senior Notes due 2021 (the “2021 Notes”), and used the net proceeds plus excess cash to prepay $500 million under the Company's U.S. sub-facility of the Term Loan Facility (see discussion below under “5.375% Senior Notes due 2021” for additional information). The prepayment satisfied all remaining quarterly repayment obligations under the U.S. sub-facility. As a result, the Company recorded a non-cash pre-tax loss on debt extinguishment of $13.2 million in the fourth quarter of 2013. WESCO will amortize the remaining debt discount and financing costs over the life of the instrument. Non-cash interest expense of $2.2 million and $0.1 million was recorded for the years ended December 31, 2013 and 2012, respectively.

Borrowings under the Term Loan Facility bear interest at base rates plus applicable margins. At December 31, 2013, the interest rates on borrowings under the Canadian sub-facility and U.S. sub-facility were approximately 5.3% and 3.75%, respectively. At December 31, 2012, the interest rates on borrowings under the Canadian sub-facility and U.S. sub-facility were approximately 5.2% and 4.5%, respectively. The Canadian Borrower will pay quarterly installments of principal equal to 0.25% of the original principal amount of its term loan sub-facility, plus accrued and unpaid interest. To the extent not previously paid, the term loans will become due and payable on December 12, 2019, with any unpaid incremental term loans becoming due and payable on the respective maturity dates applicable to those incremental term loans. Other than in certain circumstances prior to June 13, 2014, at any time or from time to time, the Borrowers may prepay borrowings under the Term Loan Facility in whole or in part without premium or penalty. The Borrowers' obligations under the Term Loan Facility are secured by substantially all of the assets of the Borrowers, the Company and certain of the Company's other subsidiaries; provided that, with respect to borrowings under the U.S. sub-facility, the collateral does not include assets of certain foreign subsidiaries or more than 65% of the issued and outstanding equity interests in certain foreign subsidiaries.

The Term Loan Facility contains customary affirmative and negative covenants for credit facilities of this type. The Term Loan Facility also provides for customary events of default.

5.375% Senior Notes due 2021

In November 2013, WESCO Distribution issued $500 million aggregate principal amount of 2021 Notes through a private offering exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). The 2021 Notes were issued at 100% of par and are governed by an indenture (the “Indenture”) entered into on November 26, 2013 with WESCO International and U.S. Bank National Association, as trustee. The 2021 Notes are unsecured senior obligations of WESCO Distribution and are guaranteed on a senior unsecured basis by WESCO International. The 2021 Notes bear interest at a stated rate of 5.375%, payable semi-annually in arrears on June 15 and December 15 of each year, with the first interest payment occurring on June 15, 2014. In addition, WESCO recorded deferred financing fees related to the issuance of the 2021 Notes totaling $8.2 million which will be amortized over the life of the notes. The 2021 Notes mature on December 15, 2021. The net proceeds of the 2021 Notes were used to prepay a portion of the U.S. Term Loan sub-facility.

At any time on or after December 15, 2016, WESCO Distribution may redeem all or a part of the 2021 Notes. Between December 15, 2016 and December 14, 2017, WESCO Distribution may redeem all or a part of the 2021 Notes at a redemption price equal to 104.031% of the principal amount. Between December 15, 2017 and December 14, 2018, WESCO Distribution may redeem all or a part of the 2021 Notes at a redemption price equal to 102.688% of the principal amount. Between December 15, 2018 and December 14, 2019, WESCO Distribution may redeem all or a part of the 2021 Notes at a redemption price equal to 101.344% of the principal amount. On and after December 15, 2019, WESCO Distribution may redeem all or a part of the 2021 Notes at a redemption price equal to 100% of the principal amount.

The Indenture governing the 2021 Notes contains customary covenants and customary events of default. In addition, upon a change of control, the holders of 2021 Notes have the right to require WESCO Distribution to repurchase all or any part of the 2021 Notes at a redemption price equal to 101% of the principal amount, plus accrued and unpaid interest.

Mortgage Financing Facility

In 2003, WESCO finalized a mortgage financing facility of $51 million. This facility was extinguished with repayments of $26.4 million in the first quarter of 2013. The interest rate on borrowings under this facility was fixed at 6.5%.

48

Accounts Receivable Securitization Facility

On September 20, 2013, WESCO Distribution and its subsidiary WESCO Receivables Corp. entered into an amendment (the “Amendment”) of the Third Amended and Restated Receivables Purchase Agreement (the “Receivables Facility”). The Amendment increased the purchase limit under the Receivables Facility from $475 million to $500 million, with the opportunity to exercise an accordion feature which permits increases in the purchase limit of up to an additional $100 million, extended the term of the Receivables Facility to September 20, 2016, and added and amended certain defined terms. The Amendment also reduced the interest rate spread and commitment fee from 1.10% to 0.95% and from 0.55% to 0.45%, respectively. Substantially all other provisions of the Receivables Facility remained unchanged.

Under the Receivables Facility, WESCO sells, on a continuous basis, an undivided interest in all domestic accounts receivable to WESCO Receivables Corp., a wholly owned special purpose entity (the “SPE”). The SPE sells, without recourse, a senior undivided interest in the receivables to financial institutions for cash while maintaining a subordinated undivided interest in the receivables, in the form of overcollateralization. WESCO has agreed to continue servicing the sold receivables for the third-party conduits and financial institutions at market rates; accordingly, no servicing asset or liability has been recorded.

As of December 31, 2013 and 2012, accounts receivable eligible for securitization totaled approximately $586.4 million and $601.1 million, respectively. The consolidated balance sheets as of December 31, 2013 and 2012 include $453.6 million and $445.0 million, respectively, of account receivable balances legally sold to third parties, as well as borrowings for equal amounts. At December 31, 2013 and 2012, the interest rate on borrowings under this facility was approximately 1.2% and 1.4%, respectively.

Revolving Credit Facility

The revolving credit facility (the “Revolving Credit Facility”) was entered into pursuant to the terms and conditions of an Amended and Restated Credit Agreement, dated as of December 12, 2012 (the “Credit Agreement”), among WESCO Distribution, the other US Borrowers party thereto, WESCO Distribution Canada LP (“WESCO Canada”) and WDCC, as Canadian Borrowers, the other Loan Parties party thereto, the Lenders party thereto, JPMorgan Chase Bank, N.A., as Administrative Agent, and JPMorgan Chase Bank, N.A., Toronto Branch, as Canadian Administrative Agent. Subsequent to the acquisition of EECOL on December 14, 2012, EECOL was added as a Canadian Borrower. On November 19, 2013, WESCO Distribution and certain other subsidiaries of the Company entered into a First Amendment to Amended and Restated Credit Agreement and Waiver (the “First Amendment”). The First Amendment, among other things, revised certain covenants and financial statement covenant calculations in the Credit Agreement. The Revolving Credit Facility contains an accordion feature allowing WESCO Distribution to request increases to the borrowing commitments under the Credit Facility of up to US $100 million in the aggregate.

The Revolving Credit Facility matures in August 2016 and consists of two separate sub-facilities: (i) a Canadian sub-facility with a borrowing limit of up to US $400 million, which is collateralized by substantially all assets of WESCO Canada, WDCC and EECOL, and (ii) a U.S. sub-facility with a borrowing limit of up to US $600 million less the amount of outstanding borrowings under the Canadian sub-facility. The U.S. sub-facility is collateralized by substantially all assets of WESCO Distribution and its U.S. subsidiaries other than real property and accounts receivable sold or intended to be sold pursuant to the Receivables Facility. Availability under the Revolving Credit Facility is based upon the amount of eligible inventory and receivables applied against certain advance rates. The applicable interest rate for borrowings under the Revolving Credit Facility includes interest rate spreads based on available borrowing capacity that range between 1.50% and 2.00% for LIBOR and CDOR-based borrowings and 0.50% and 1.00% for prime rate-based borrowings. The otherwise applicable interest rate is reduced by 0.25% if the Company's leverage ratio falls below a ratio of 2.5 to 1.0. At December 31, 2013, the interest rate on borrowings under this facility was approximately 3.5%.

The Credit Agreement contains customary affirmative and negative covenants for credit facilities of this type. Subject to the terms of the Credit Agreement, the Company is permitted to pay dividends, repurchase common stock or repurchase indebtedness without limitation so long as pro forma combined availability under the Revolving Credit Facility and the Receivables Facility exceeds US $163.8 million and the adjusted fixed charge ratio is not less than a ratio of 1.1 to 1.0.

During 2013, WESCO borrowed $833.5 million in the aggregate under the Revolving Credit Facility and made repayments in the aggregate amount of $1,026.7 million. During 2012, aggregate borrowings and repayments were $814.1 million and $632.9 million, respectively. WESCO had $512.2 million available under the Revolving Credit facility at December 31, 2013, after giving effect to outstanding letters and international lines of credit, as compared to approximately $270.9 million at December 31, 2012.

7.50% Senior Subordinated Notes due 2017

On December 10, 2012, WESCO International announced that WESCO Distribution would redeem all of its outstanding 2017 Notes on January 9, 2013 (the “Redemption Date”) at a redemption price equal to 101.250% of the principal amount thereof plus accrued and unpaid interest to, but excluding, the Redemption Date, for a total of $1,030 per $1,000 principal amount of 2017 Notes. The aggregate principal amount of 2017 Notes outstanding was $150 million. On December 11, 2012, in accordance with the terms of the Indenture, dated as of September 27, 2005, among WESCO Distribution, WESCO International and The Bank of New York Mellon, as trustee (the “Trustee”), WESCO Distribution irrevocably deposited with the Trustee funds sufficient to pay principal and interest of all outstanding 2017 Notes on the Redemption Date. As a result, the Indenture was satisfied and discharged.

International Lines of Credit

Certain foreign subsidiaries of WESCO have entered into uncommitted lines of credit, which serve as overdraft facilities, to support local operations. The maximum borrowing limit varies by facility and ranges between US $1.0 million and US $15.0 million. The applicable interest rate for borrowings under these lines of credit varies by country and is governed by the applicable loan agreement. The international lines of credit are renewable on an annual basis and certain facilities are fully and unconditionally guaranteed by WESCO Distribution. Accordingly, these lines directly reduce availability under the Revolving Credit Facility.

1.75% Convertible Senior Debentures due 2026

Proceeds of $300 million were received in connection with the issuance of the 2026 Debentures by WESCO International in November 2006. On August 27, 2009, WESCO International completed an exchange offer pursuant to which it issued $345 million in aggregate principal amount of 2029 Debentures in exchange for approximately $299.7 million and $57.7 million in aggregate principal amounts of its outstanding 2026 Debentures and 2025 Debentures, respectively (see the 6.0% Convertible Senior Debentures due 2029 discussion below for additional information). On November 30, 2011, WESCO International announced that it would redeem all of its 2026 Debentures on January 3, 2012. WESCO International redeemed the remaining $0.1 million aggregate principal amount of outstanding 2026 Debentures at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest. Following the redemption on January 3, 2012, there were no 2026 Debentures outstanding.

6.0% Convertible Senior Debentures due 2029

On August 27, 2009, WESCO International completed an exchange offer pursuant to which it issued $345 million in aggregate principal amount of 2029 Debentures in exchange for approximately $299.7 million and $57.7 million in aggregate principal amounts of its outstanding 2026 Debentures and 2025 Debentures, respectively. As a result of the debt exchange, WESCO recorded a gain of $6.0 million, which included the write-off of debt issuance costs. The 2029 Debentures were issued pursuant to an Indenture dated August 27, 2009 (the “Indenture”), with The Bank of New York Mellon, as trustee, and are unconditionally guaranteed on an unsecured senior subordinate basis by WESCO Distribution.

WESCO utilized an interest rate of 13.875% to reflect the non-convertible debt borrowing rate of its offering upon issuance, which was determined based on discussions with its financial institutions and a review of relevant market data, and resulted in a $181.2 million discount to the 2029 Debenture balance and a net increase in additional capital of $106.5 million. In addition, the financing costs related to the issuance of the 2029 Debentures were allocated between the debt and equity components. WESCO is amortizing the debt discount and financing costs over the life of the instrument. Non-cash interest expense of $3.3 million and $2.2 million was recorded for the years ended December 31, 2013 and 2012, respectively. The debt discount amortization will approximate $3.4 million in 2014, $3.9 million in 2015, $4.5 million in 2016, $5.1 million in 2017, and $5.8 million in 2018.

While the 2029 Debentures accrue interest at an effective interest rate of 13.875% (as described above), the coupon interest rate of 6.0% per annum is payable in cash semi-annually in arrears on each March 15 and September 15. Beginning with the six-month period commencing September 15, 2016, WESCO International will also pay contingent interest during any six-month period in which the trading price of the 2029 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 2029 Debentures. During any six-month period when contingent interest shall be payable, the contingent interest payable per $1,000 principal amount of 2029 Debentures will equal 0.25% of the average trading price of $1,000 principal amount of the 2029 Debentures during the five trading days ending on the second trading day immediately preceding the first day of the applicable six-month interest period. In accordance with guidance related to derivatives and hedging, the contingent interest feature of the 2029 Debentures is an embedded derivative that is not considered clearly and closely related to the host contract. The contingent interest component had no significant value at December 31, 2013 or 2012.

50

The 2029 Debentures are convertible into cash, and in certain circumstances, shares of WESCO International's common stock, $0.01 par value, at any time on or after September 15, 2028, or prior to September 15, 2028 in certain circumstances. The 2029 Debentures will be convertible based on an initial conversion rate of 34.6433 shares of common stock per $1,000 principal amount of the 2029 Debentures (equivalent to an initial conversion price of approximately $28.87 per share). The conversion rate and conversion price may be adjusted under certain circumstances.

At any time on or after September 15, 2016, the Company may redeem all or a part of the 2029 Debentures plus accrued and unpaid interest (including contingent interest and additional interest, if any) to, but not including, the redemption date. If WESCO International undergoes certain fundamental changes, as defined in the Indenture, prior to maturity, holders of the 2029 Debentures will have the right, at their option, to require WESCO International to repurchase for cash some or all of their 2029 Debentures at a repurchase price equal to 100% of the principal amount of the 2029 Debentures being repurchased, plus accrued and unpaid interest (including contingent interest and additional interest, if any) to, but not including, the repurchase date.

The following table sets forth the components of WESCO’s outstanding convertible debenture indebtedness:

Debt discount on convertible debentures and term loan facility	(174,686		)
Total debt	$	1,487,695

WESCO’s credit agreements contain various restrictive covenants that, among other things, impose limitations on (i) dividend payments or certain other restricted payments or investments; (ii) the incurrence of additional indebtedness and guarantees; (iii) creation of liens; (iv) mergers, consolidation or sales of substantially all of WESCO’s assets; (v) certain transactions among affiliates; (vi) payments by certain subsidiaries to WESCO; and (vii) capital expenditures. In addition, the revolving credit agreement and Receivables Facility require WESCO to meet certain fixed charge coverage tests depending on availability or liquidity, respectively.

8. CAPITAL STOCK

Preferred Stock

There are 20 million shares of preferred stock authorized at a par value of $.01 per share. The Board of Directors has the authority, without further action by the stockholders, to issue all authorized preferred shares in one or more series and to fix the number of shares, designations, voting powers, preferences, optional and other special rights and the restrictions or qualifications thereof. The rights, preferences, privileges and powers of each series of preferred stock may differ with respect to dividend rates, liquidation values, voting rights, conversion rights, redemption provisions and other matters.

51

Common Stock

There are 210 million shares of common stock and 20 million shares of Class B common stock authorized at a par value of $.01 per share. The Class B common stock is identical to the common stock, except for voting and conversion rights. The holders of Class B common stock have no voting rights. With certain exceptions, Class B common stock may be converted, at the option of the holder, into the same number of shares of common stock.

Under the terms of the Revolving Credit Facility and the Term Loan Agreement, WESCO International is restricted from declaring or paying dividends and as such, at December 31, 2013 and 2012, no dividends had been declared, and therefore no retained earnings were reserved for dividend payments.

Additional Capital

WESCO separately accounts for the liability and equity components of its 2029 Debentures and 2026 Debentures in a manner that reflects its non-convertible debt borrowing rate. As of December 31, 2013 and 2012, the net equity included in additional capital related to the 2029 Debentures and 2026 Debentures totaled $106.3 million.

As of December 31, 2013, WESCO’s foreign subsidiaries had unremitted earnings of approximately $525.6 million, which would be subject to tax at the U.S. tax rate, net of applicable foreign tax credits. WESCO asserts that these earnings are permanently reinvested and, therefore, has not provided a deferred tax liability on these earnings. WESCO’s current plans do not require it to repatriate these earnings to fund liquidity needs in the U.S. and it intends to utilize these earnings to fund growth in foreign markets. It is not practicable for WESCO to determine the deferred tax liability associated with repatriation of these earnings as such determination involves material uncertainties about the potential extent and timing of any distributions, the availability and complexity of calculating foreign tax credits, and the potential indirect tax consequences of such distributions, including withholding taxes.

The following table sets forth deferred tax assets and liabilities:

As of December 31, 2013 and 2012, WESCO had deferred tax assets of $3.8 million and $4.4 million, respectively, related to state net operating loss carryforwards. These carryforwards expire beginning in 2014 through 2026. As of December 31, 2013 and 2012, WESCO had deferred tax assets of $30.3 million and $18.9 million, respectively, related to Canadian net operating loss carryforwards. These carryforwards expire beginning in 2028 through 2029. In addition, WESCO had deferred tax assets of $1.8 million as of December 31, 2013 related to Mexican net operating loss carryforwards. These carryforwards expire in 2023. The Company has determined that it more-likely-than-not will utilize these net operating loss carryforwards before expiration and, accordingly, has not recorded any valuation allowance.

53

The Company is under examination by tax authorities in the United States and Canada and remains subject to examination until the applicable statutes of limitation expire. The statutes of limitation for the material jurisdictions in which the Company files income tax returns remain open as follows:

United States — Federal	1996, 1997, 2000 - 2008, 2009 and forward
United States — Material States	2010 and forward
Canada	2004 and forward

The statutes of limitation with respect to the Company’s 1996, 1997, and 2000-2007 U.S. federal income tax returns are open by waiver only, in connection with Mutual Agreement Procedure proceedings under the income tax treaty between the U.S. and Canada. The statute of limitation with respect to the Company’s 2008 U.S. federal income tax return is open by waiver only, in connection with Advance Pricing Agreement negotiations between the U.S. and Canada. The statute of limitation with respect to the Company’s 2009 U.S. Federal income tax return is open by waiver in connection with the IRS examination of that year.

The recognition and measurement of tax benefits associated with uncertain income tax positions requires the use of judgment and estimates by management, which are inherently subjective. Changes in judgment about uncertain tax positions taken in previous periods may result from new information concerning an uncertain tax position, completion of an audit, or expiration of statutes of limitation. These changes may create volatility in the Company’s effective tax rate in future periods.

The following table sets forth the reconciliation of gross unrecognized tax benefits:

	December 31,

Foreign currency translation	(558		)	—			—
Ending balance December 31	$	25,548		$	21,075		$	20,878

*In 2011, additions for tax positions of prior years primarily relate to transfer pricing adjustments made by Canada Revenue Agency, which are subject to Mutual Agreement Procedure proceedings under the U.S./Canada income tax treaty. The Company recorded an offsetting deferred tax asset in the amount of $23.1 million, excluding interest, related to the correlative impact of these adjustments on the Company’s U.S. income tax liability.

The total amount of unrecognized tax benefits were $25.5 million, $21.1 million, and $20.9 million as of December 31, 2013, 2012, and 2011, respectively. The amount of unrecognized tax benefits that would affect the effective tax rate if recognized in the consolidated financial statements was $25.7 million, $21.2 million, and $19.7 million, respectively. These amounts would be offset by deferred tax expense resulting from the reversal of the deferred tax asset discussed above. The amounts recognized would be discrete items in the quarter recognized.

It is reasonably possible that the amount of unrecognized tax benefits will decrease by approximately $19.6 million within the next twelve months due to the effective settlement of uncertain tax positions related to transfer pricing adjustments made by Canada Revenue Agency and/or the expiration of statutes of limitation. Of this amount, approximately $16.4 million could be offset by deferred tax expense as discussed above.

The Company classifies interest related to unrecognized tax benefits as interest expense in the consolidated statement of income. As of December 31, 2013, 2012 and 2011, WESCO had an accrued liability of $8.6 million, $8.0 million and $11.4 million respectively, for interest expense related to unrecognized tax benefits. The Company classifies penalties related to unrecognized tax benefits as part of income tax expense. Penalties recorded as part of income tax expense were immaterial in amount in 2013, 2012, and 2011, respectively.

10. EARNINGS PER SHARE

Basic earnings per share are computed by dividing net income by the weighted average common shares outstanding during the periods. Diluted earnings per share are computed by dividing net income by the weighted average common shares and common share equivalents outstanding during the periods. The dilutive effect of common share equivalents is considered in the diluted earnings per share computation using the treasury stock method, which includes consideration of stock-based compensation.

The following table sets forth the details of basic and diluted earnings per share:

	Year Ended December 31
	2013		2012		2011
(In thousands, except per share data)
Net income attributable to WESCO International, Inc.	$	276,430	$	201,777	$	196,251
Weighted average common shares outstanding used in computing basic earnings per share	44,148		43,677		43,220
Common shares issuable upon exercise of dilutive stock options	1,121		1,147		1,179
Common shares issuable from contingently convertible debentures (see below for basis of calculation)	7,381		6,310		5,224
Weighted average common shares outstanding and common share equivalents used in computing diluted earnings per share	52,650		51,133		49,623
Earnings per share attributable to WESCO International, Inc.
Basic	$	6.26	$	4.62	$	4.54
Diluted	$	5.25	$	3.95	$	3.96

As of December 31, 2013, 2012 and 2011, the computation of diluted earnings per share attributable to WESCO International, Inc. excluded stock-settled stock appreciation rights of approximately 0.3 million, 0.9 million and 1.2 million at weighted average exercise prices of $66.08 per share, $64.17 per share and $62.48 per share, respectively. These amounts were excluded because their effect would have been antidilutive.

Because of WESCO’s obligation to settle the par value of the 2029 Debentures in cash, WESCO is not required to include any shares underlying the 2029 Debentures in its diluted weighted average shares outstanding until the average stock price per share for the period exceeds the conversion price of the 2029 Debentures. At such time, only the number of shares that would be issuable (under the treasury stock method of accounting for share dilution) will be included, which is based upon the amount by which the average stock price exceeds the conversion price. The conversion price of the 2029 Debentures is $28.87. Share dilution is limited to a maximum of 11,948,513 shares for the 2029 Debentures. For the periods ended December 31, 2013, 2012, and 2011, the effect of the 2029 Debentures on diluted earnings per share attributable to WESCO International, Inc. was a decrease of $0.86, $0.56, and $0.47, respectively.

11. EMPLOYEE BENEFIT PLANS

Defined Contribution Plans

     A majority of WESCO’s employees are covered by defined contribution retirement savings plans for their service rendered subsequent to WESCO’s formation. WESCO also offers a deferred compensation plan for select individuals. For U.S. participants, WESCO will make contributions in an amount equal to 50% of the participant’s total monthly contributions up to a maximum of 6% of eligible compensation. For Canadian participants, WESCO will make contributions in an amount ranging from 1% to 7% of the participant’s eligible compensation based on years of continuous service. In addition, employer contributions may be made at the discretion of the Board of Directors. Discretionary employer contributions charges of $18.6 million and $16.2 million were incurred 2012 and 2011, respectively. For the years ended December 31, 2013, 2012 and 2011, WESCO incurred charges of $22.1 million, $31.8 million, and $27.6 million, respectively, for all such plans. Contributions are made in cash to employee retirement savings plan accounts. Employees then have the option to transfer balances allocated to their accounts into any of the available investment options, including WESCO common stock.

Defined Benefit Plans

     In connection with the December 14, 2012 acquisition of EECOL discussed in Note 5, the Company assumed a contributory defined benefit plan covering all employees of EECOL. The plan provides retirement benefits based on earnings and credited service, and participants may contribute 2% of their earnings to the plan. Participants become 100% vested after two years of continuous service.

     The Company also assumed EECOL's Supplemental Executive Retirement Plan (SERP) which provides additional pension benefits to certain executives based on earnings, credited service, and executive service. Participants in the plan are vested after two years of continuous service and may contribute 4% of their earnings to the plan.

     The following tables present the changes in benefit obligations, plan assets and funded status for the pension plans and the components of net periodic pension cost.

2016	2,427
2017	2,549
2018	2,608
2019-2024	19,297

     The Company expects to contribute approximately $3.0 million to the plans in 2014.

The Company's pension plan weighted asset allocations as of December 31, 2013 by asset category are as follows:

Asset Category
Equity securities	57.1	%
Debt securities	42.9	%
	100.0	%

     The Plan's long-term overall objective is to maintain benefits at their current level without affecting the cost of maintaining the plan, assuming that the demographic make-up of the group of members remains the same.

57

     The primary investment objective, in support of the overall objective, is to earn the highest rate of return possible for the Plan, while keeping risk at acceptable levels. The long-term return objective of the Plan is to achieve a minimum annualized rate of return in excess of the actuarial requirements. This translates into a required return of 3.5% percent above inflation, net of investment management fees. The return objective is consistent with the overall investment risk level that the Plan assumes in order to meet the pension obligations of the Plan. To achieve this long term investment objective, the Plan has adopted an asset mix that has a combination of equity and fixed income investments. Risk is controlled by investing in a well-diversified portfolio of asset classes. To meet this objective, a benchmark portfolio is established based on the expected returns for each asset class available. The investment of the Plan's assets in accordance with the benchmark portfolio should enable the Plan to not only attain, but also exceed the minimum overall objective.

     The following table presents the target asset mix based on market value for each investment category within which the investment managers must invest the Plan's assets. The manager is required to rebalance the asset mix back to the target on a quarterly basis.

Asset Category	Target %
Canadian equities	25	%
U.S. equities	15	%
Non-North American equities	20	%
Total equities	60	%
Fixed income bond managers	40	%

     Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity's own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:

• Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

• Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset and liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

• Level 3 - Inputs that are both significant to the fair value measurement and unobservable.

     The following section describes the valuation methodologies used by the trustees to measure the fair value of plan assets, including an indication of the level in the fair value hierarchy in which each type of asset is generally classified.

Equity Securities. These securities consist of the plan's share of segregated funds that invest in the stock of publicly traded companies and are valued at the net asset value of shares held at December 31. As such, these securities are generally included in Level 2.

Debt Securities. These securities consist of segregated funds that invest in publicly traded U.S and non-U.S. fixed interest obligations and government securities and are valued through consultation and evaluation with brokers in the institutional market using other observable market data. As such, these securities are generally included in Level 2. Also, these securities include cash and cash equivalents consisting of money market funds and are generally valued using quoted prices or observable market data. As such, these funds are included in Level 1.

     The fair value methods described above may not be indicative of net realizable value or reflective of future fair values. Additionally, while the Company believes the valuation method used by the plan's trustee is appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

58

     The following table represents the fair value of plan assets classified under the appropriate level of fair value hierarchy:

	Level 1		Level 2		Level 3		Total
Equity securities	$	—	$	50,023	$	—	$	50,023
Debt securities	389		37,194		—		37,583
Total investments	$	389	$	87,217	$	—	$	87,606

12. STOCK-BASED COMPENSATION

WESCO has sponsored four stock option plans: the 1999 Long-Term Incentive Plan, as amended and restated (“LTIP”), the 1998 Stock Option Plan, the Stock Option Plan for Branch Employees and the 1994 Stock Option Plan. The LTIP was designed to be the successor plan to all prior plans. Any shares remaining reserved for future issuance under the prior plans are available for issuance under the LTIP. The LTIP and predecessor plans are administered by the Compensation Committee of the Board of Directors.

On May 30, 2013, the Company renewed and restated the LTIP, increasing the maximum number of shares of common stock that may be issued under the plan by 1.6 million shares to 4.0 million. Under the LTIP, the total number of shares of Common Stock authorized to be issued under the LTIP will be reduced by 1 share of Common Stock for every 1 share that is subject to an option or stock appreciation right granted under the LTIP on or after May 30, 2013, and 1.83 shares of Common Stock for every 1 share that was subject to an award other than an option or stock appreciation right granted on or after May 30, 2013. As of December 31, 2013, 4.0 million shares of common stock were reserved under the LTIP for future equity award grants.

Except for the performance-based award, awards granted vest and become exercisable once criteria based on time is achieved. Performance-based awards vest based on market or performance conditions. All awards vest immediately in the event of a change in control. Each award terminates on the tenth anniversary of its grant date unless terminated sooner under certain conditions.

WESCO recognized $15.9 million, $15.1 million and $15.4 million of non-cash stock-based compensation expense, which is included in selling, general and administrative expenses, in 2013, 2012 and 2011, respectively. As of December 31, 2013, there was $17.2 million of total unrecognized compensation expense related to non-vested stock-based compensation arrangements for all awards previously made of which approximately $10.7 million is expected to be recognized in 2014, $5.7 million in 2015 and $0.8 million in 2016.

The total intrinsic value of awards exercised during the years ended December 31, 2013, 2012, and 2011 was $23.4 million, $41.1 million, and $13.8 million, respectively. The total amount of cash received from the exercise of options was less than $0.1 million, $3.2 million, and $0.4 million, respectively. The tax benefit associated with the exercise of stock options and stock-settled stock appreciation rights totaled $8.4 million, $11.4 million, and $5.4 million in 2013, 2012, and 2011, respectively. WESCO uses the direct only method and tax law ordering approach to calculate the tax effects of stock-based compensation. The tax benefit was recorded as a credit to additional paid-in capital.

The following table sets forth a summary of both stock options and stock appreciation rights and related information for the years indicated:

	2013							2012				2011
	Awards		Weighted Average Exercise Price		Weighted Average Remaining Contractual Life	Aggregate Intrinsic Value (In thousands)		Awards		Weighted Average Exercise Price		Awards		Weighted Average Exercise Price

WESCO granted the following stock-settled stock appreciation rights at the following weighted average assumptions:

	2013	2012	2011
Stock-settled appreciation rights granted	253,999	257,932	399,260
Risk free interest rate	0.9%	0.9%	2.3%
Expected life (in years)	5.0	5.0	5.0
Expected volatility	50%	50%	49%

The following table sets forth a summary of time-based restricted stock units and related information for the year ended December 31, 2013:

	Awards		Weighted Average Fair Value
Unvested at December 31, 2012	187,335		$	52.28
Granted	69,393		72.15
Vested	(65,705	)	33.63
Forfeited	(6,277	)	61.03
Unvested at December 31, 2013	184,746		$	66.08

The weighted average fair value per stock-settled appreciation right granted was $31.34, $27.89 and $26.46 for the years ended December 31, 2013, 2012 and 2011, respectively. The weighted average fair value per restricted stock unit granted was $72.15, $64.27 and $60.05 for the years ended December 31, 2013, 2012 and 2011, respectively.

The following table sets forth a summary of performance-based awards for the year ended December 31, 2013:

	Awards		Weighted Average Fair Value
Unvested at December 31, 2012	46,500		$	75.72
Granted	48,058		78.20
Vested	—		—
Forfeited	(2,074	)	76.66
Unvested at December 31, 2013	92,484		$	76.98

The unvested performance-based awards at December 31, 2013 includes 46,242 market-based performance awards. The number of shares that vest from these awards will be dependent upon WESCO's total stockholder return over a three-year period in relation to the total stockholder return of a select group of peer companies. These awards are valued based upon a Monte Carlo simulation model. The probability of meeting the market criteria was considered when calculating the estimated fair market value on the date of grant. These awards were accounted for as awards with market conditions, which are recognized over the service period, regardless of whether the market conditions are achieved and the awards ultimately vest.

60

The fair value of the performance shares based on total stockholder return granted during the year ended December 31, 2013 were estimated using the following weighted-average assumptions:

Weighted Average Assumptions
Grant date share price	$	72.15
WESCO expected volatility	37.8		%
Peer group median volatility	29.1		%
Risk-free interest rate	0.38		%
Correlation	116.8		%

Vesting of the remaining 46,242 shares of performance-based awards in the table above will be dependent upon the three-year average growth rate of WESCO's net income. These awards are valued based upon the grant-date closing price of WESCO's common stock. These awards were accounted for as awards with performance conditions, accordingly stock-based compensation expense is recognized over the performance period and considers the probability that the performance targets will be achieved.

13. COMMITMENTS AND CONTINGENCIES

Rental expense for the years ended December 31, 2013, 2012 and 2011 was $60.0 million, $50.0 million and $48.0 million, respectively.

From time to time, a number of lawsuits and claims have been or may be asserted against WESCO relating to the conduct of its business, including routine litigation relating to commercial and employment matters. The outcomes of litigation cannot be predicted with certainty, and some lawsuits may be determined adversely to WESCO. However, management does not believe that the ultimate outcome is likely to have a material adverse effect on WESCO’s financial condition or liquidity, although the resolution in any fiscal quarter of one or more of these matters may have a material adverse effect on WESCO’s results of operations for that period.

As initially reported in our 2008 Annual Report on Form 10-K, WESCO is a defendant in a lawsuit filed in a state court in Indiana in which a customer, ArcelorMittal Indiana Harbor, Inc. (“AIH”), alleges that the Company sold defective products to AIH in 2004 that were supplied to the Company by others. The lawsuit sought monetary damages in the amount of approximately $50 million. On February 14, 2013, the jury returned a verdict in favor of AIH and awarded damages in the amount of approximately $36.1 million, and judgment was entered on the jury's verdict. As a result, the Company recorded a $36.1 million charge to selling, general and administrative expenses in 2012. The Company disputes this outcome and filed a post-trial motion challenging the verdict alleging various errors that occurred during trial. The Company received letters from its insurers confirming insurance coverage of the matter and recorded a receivable in the quarter ended March 31, 2013 in an amount equal to the previously recorded liability. AIH also filed a post-trial motion asking the court to award additional amounts to AIH, including prejudgment and post-judgment interest. The Court denied the Company's post-trial motion on June 28, 2013 and granted in part AIH's motion, awarding prejudgment interest in the amount of $3.9 million and ordering post-judgment interest to accrue on the entire judgment at 8% per annum. In the quarter ended June 30, 2013, the Company received letters from its insurers confirming insurance coverage of all prejudgment and post-judgment interest related to the matter, and recorded a liability and a corresponding receivable in the amount of $4.7 million for all interest accrued in connection with this matter. Final judgment was entered by the court on July 16, 2013, and the Company is appealing the judgment. The Company

61

has recorded an additional liability and a corresponding receivable in the amount of $1.6 million for post-judgment interest accrued in connection with this matter in the second half of 2013. The judgment may increase or decrease based on the outcome of the appellate proceedings that cannot be predicted with certainty.

The Company revised its condensed consolidating balance sheet as of December 31, 2012 to include WESCO Finance Corporation ("WESCO Finance"), a subsidiary of WESCO International, as a non-guarantor subsidiary. Previously, WESCO Finance was included in the WESCO International column of the Company's condensed consolidating balance sheets. In doing so, the Company recorded the $480.2 million investment in WESCO Finance as an increase in investments in affiliates, with an offsetting increase in intercompany payables, net. The Company increased intercompany receivables, net by $679.9 million with a corresponding increase in stockholders' equity of non-guarantor subsidiaries to record WESCO Finance as a non-guarantor subsidiary. Additionally, the Company recorded the cumulative accrued interest payable of $198.1 million related to an intercompany loan between WESCO Distribution and WESCO Finance by adjusting the stockholders' equity of WESCO Distribution at December 31, 2012 with a corresponding increase in intercompany payables, net. The Company also decreased non-current liabilities of WESCO International by $1.6 million with a corresponding increase to intercompany payable, net at December 31, 2012. The Company made additional immaterial revisions related to other intercompany transactions in the condensed consolidating balance sheet at December 31, 2012.

The Company revised its condensed consolidating statements of income and comprehensive income for interest expense related to intercompany borrowings, increasing interest expense of WESCO Distribution by $29.2 million and $27.9 million and decreasing interest expense of non-guarantor subsidiaries by $29.2 million and $27.9 million for the years ended December 31, 2012 and 2011, respectively. In addition, the Company revised its methodology for allocating income tax expense during interim reporting periods, resulting in a decrease in income tax expense of WESCO International by $17.1 million and $16.3 million, a decrease in income tax expense of WESCO Distribution by $9.6 million and $5.0 million and an increase in income tax expense of non-guarantor subsidiaries by $26.7 million and $21.3 million for the years ended December 31, 2012 and 2011, respectively.

The Company revised its condensed statements of cash flows to present proceeds from issuance of debt and repayments of debt for the years ended December 31, 2012 and 2011. For the year ended December 31, 2012, the Company revised its condensed statement of cash flows to properly classify debt between WESCO Distribution (proceeds of $1,145.3 million and repayments of $469.2 million) and non-guarantor subsidiaries (proceeds of $1,179.1 million and repayments of $784.8 million). For the year ended December 31, 2011, the Company revised its condensed statement of cash flows to properly classify debt between WESCO Distribution (proceeds of $291.3 million and repayments of $264.4 million) and non-guarantor subsidiaries (proceeds of $357.3 million and repayments of $466.5 million). The Company revised its condensed consolidating statements of cash flows for 2012 to reflect a $3.6 million advance from WESCO International to WESCO Distribution, and for 2011 to reflect a $7.5 million advance from WESCO Distribution to WESCO International.

The impact of the revisions noted above, which the Company has determined is not material to the consolidated financial statements taken as a whole, did not have any impact on the consolidated amounts previously reported, nor did they impact the Company's obligations under the 2029 Debentures. The prior period condensed consolidating financial statements will be similarly revised as the information is presented in the Company's first quarter Form 10-Q filing for 2014.

^(A)  Earnings per share (EPS) in each quarter is computed using the weighted average number of shares outstanding during the quarter while EPS for the full year is computed by taking the average of the weighted average number of shares outstanding each quarter. Thus, the sum of the four quarters’ EPS may not equal the full-year EPS.

^(B)  Diluted EPS in each quarter is computed using the weighted average number of shares outstanding and common share equivalents during that quarter while Diluted EPS for the full year is computed by taking the average of the weighted average number of shares outstanding and common share equivalents each quarter. Thus, the sum of the four quarters’ Diluted EPS may not equal the full-year Diluted EPS.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

None.

Item 9A. Controls and Procedures.

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of our disclosure controls and procedures as such term is defined under Rule 13a-15(e) promulgated under the Exchange Act. Based on this evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Exchange Act Rule 13a-15(f). Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the

69

risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control — Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control — Integrated Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2013.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2013 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report, which is included herein.

Changes in Internal Control Over Financial Reporting

During the last fiscal quarter of 2013, there were no changes in the Company’s internal control over financial reporting identified in connection with management’s evaluation of the effectiveness of the Company’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
