 of the Committee as needed in connection with advising the Committee. The Committee has assessed the independence of Meridian pursuant to SEC and NYSE rules and concluded that Meridian’s work for the Committee does not raise any conflict of interest. In particular, the Committee retains Meridian to prepare compensation plan reviews, identify general trends and practices in executive compensation programs, provide information on new developments, including regulatory and legislative updates, related to compensation, assist in selecting the appropriate peer group, prepare a market analysis of target total compensation for the NEOs based on comparable and similarly-sized(by revenue) companies, and furnish its input regarding the compensation and incentives of the Chief Executive Officer and other executives. The Committee’s Chairman meets with management and Meridian regularly throughout the course of the year. The Committee reports to the entire Board of Directors at every Board meeting on its activities, the research commissioned from our compensation consultant and on the Committee’s specific compensation deliberations and decisions that directly affect our executive leadership team. Compensation Peer Group As part of our compensation review process, the Committee annually assesses the competitiveness of the target pay opportunities for each of our NEOs against similarly situated executives from a custom peer group of companies. The peer group, reviewed and approved annually by the Committee, generally reflects:

| • |     | distribution companies similar in size, but also companies from general industry (excluding companies that are demonstrably variant to Wesco – e.g., agriculture, financial services, healthcare, retail) to reflect the broader market for talent |

| • |     | companies with similar business and financial characteristics, including revenue size, margins, market capitalization and capital intensity |

We chose a large number of similarly sized companies to ensure a proper sample size for comparison purposes and because we believe that they are representative of the companies against whom we compete to recruit and retain talent. This approach has proven successful, as many of the executive officers that we recently hired came from large corporations that were not direct competitors of ours and not in the distribution industry. Furthermore, it is not feasible or appropriate to construct a peer group of only distributor competitors, as many of our competitors are smaller and/or privately-held companies, in the case of local competitors, or larger non-U.S.based companies, in the case of global competitors. To adjust for a variation in size among our
