For the six months ended June 30, 2010 and 2009, the computation of diluted earnings per share excluded stock-settled stock appreciation rights of 1.8 million and 3.0 million, respectively, at weighted average exercise prices of $52 per share and $43 per share, respectively. These amounts were excluded because their effect would have been antidilutive. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Because of WESCO’s obligation to settle the par value of the 2.625% Convertible Senior Debentures due 2025 (the “2025 Debentures”), the 1.75% Convertible Senior Debentures due 2026 (the “2026 Debentures”) and the 6.0% Convertible Senior Debentures due 2029 (the “2029 Debentures” and together with the 2025 Debentures and 2026 Debentures, the “Debentures”) in cash, WESCO is not required to include any shares underlying the Debentures in its diluted weighted average shares outstanding until the average stock price per share for the period exceeds the conversion price of the respective Debentures. At such time, only the number of shares that would be issuable (under the treasury stock method of accounting for share dilution) would be included, which is based upon the amount by which the average stock price exceeds the conversion price. The conversion prices of the 2029 Debentures, 2026 Debentures and 2025 Debentures are $28.87, $88.15 and $41.86, respectively. Share dilution is limited to a maximum of 11,951,939 shares for the 2029 Debentures, 2,507 shares for the 2026 Debentures and 2,205,434 shares for the 2025 Debentures. Since the average stock prices for the three and six month periods ended June 30, 2010 were $37.52 per share and $34.13 per share, respectively, 2,756,454 shares and 1,843,267 shares, respectively, underlying the 2029 Debentures were included in the diluted share count, and the effect on diluted earnings per share for both periods was a decrease of approximately $0.04.

REVOLVING CREDIT FACILTY</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     At June 30, 2010, the aggregate borrowing capacity under the revolving credit facility was $375 million. The revolving credit facility consists of two separate sub-facilities: (i) a U.S. sub-facility and (ii) a Canadian sub-facility and includes a letter of credit sub-limit of up to $55 million. The facility matures on November 1, 2013 and is collateralized by the inventory of WESCO Distribution, Inc. (“WESCO Distribution”) and the inventory and accounts receivable of WESCO Distribution Canada, L.P. WESCO Distribution’s obligations under the revolving credit facility have been guaranteed by WESCO International, Inc. (“WESCO International”) and by certain of WESCO Distribution’s subsidiaries. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     On February 19, 2010, WESCO Distribution, along with certain of its subsidiaries, entered into a Limited Consent and Amendment No. 4 (the “Amendment”) to its Third Amended and Restated Revolving Credit Agreement, dated November 1, 2006 (the “Agreement”). The Amendment permits WESCO to complete certain legal entity restructuring actions, issue additional surety bonds and invest additional resources in foreign subsidiaries. In addition, the amendment enhances WESCO’s hedging capacities. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Pursuant to the terms of the Amendment, WESCO agreed to modify the Applicable Margins (as defined in the Agreement) paid to the lenders on borrowings and letters of credit. Availability under the facility is limited to the amount of eligible U.S. and Canadian inventory and Canadian receivables applied against certain advance rates. Depending upon the amount of excess availability under the facility, interest will be calculated at LIBOR plus a margin that ranges between 2.25% and 2.875% or at the Index Rate (prime rate published by the Wall Street Journal) plus a margin that ranges between 1.00% and 1.625%. This change represented a 1.125% to 1.25% adjustment in borrowing margin over the previous rates. The fee for unused capacity associated with the facility was not changed and will range between 0.25% and 0.375%. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     As long as the average daily excess availability for both the preceding and projected succeeding 90-day period is greater than $50 million, WESCO would be permitted to make acquisitions and repurchase outstanding public stock and bonds. The above permitted transactions would also be allowed if such excess availability is between $25 million and $50 million and WESCO’s fixed charge coverage ratio, as defined by Agreement, is at least 1.25 to 1.0 after taking into consideration the permitted transaction. Additionally, if excess availability under the revolving credit facility is less than $60 million, then WESCO must maintain a fixed charge coverage ratio of 1.1 to 1.0. At June 30, 2010, WESCO had $28.0 million outstanding under the facility. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif"> </div>

EQUITY INVESTMENT</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     During the first quarter of 2008, WESCO and Deutsch Engineered Connecting Devices, Inc. (“Deutsch”) completed a transaction with respect to WESCO’s LADD operations, which resulted in a joint venture in which Deutsch owned a 60% interest and WESCO owned a 40% interest. WESCO accounted for its investment in the joint venture using the equity method of accounting. Accordingly, earnings from the joint venture were recorded as other income in the consolidated statement of income. Deutsch was entitled, but not obliged, to acquire the remaining 40% after January 1, 2010. Deutsch paid to WESCO aggregate consideration of approximately $75.0 million, consisting of $60.0 million in cash plus a $15.0 million promissory note for its 60% interest in the joint venture. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     On January 15, 2010, WESCO received $1.8 million in accrued interest related to the promissory note for the period from January 2, 2008 to January 2, 2010. In addition, Deutsch and WESCO entered into an amended promissory note agreement. The amendment extended the maturity date for the payment of principal and interest to the earlier of (a) the closing date of Deutsch’s option to acquire the remaining 40% joint venture interest or (b) the maturity date of Deutsch’s credit facility or mezzanine financing facility. Interest accrued at a rate of 8.5% compounded annually. Management believed this rate was commensurate with a market rate of interest; therefore, no reserve or allowance was recorded against the promissory note. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     On April 30, 2010, Deutsch notified WESCO it would exercise its option to purchase the remaining 40% of the LADD joint venture. The option price for Deutsch to acquire the remaining 40% of the joint venture was determined based upon a multiple of trailing earnings, with a minimum purchase price of $40.0 million and maximum purchase price of $50.0 million. The investment in the LADD joint venture at March 31, 2010 was $43.4 million, and the estimated option exercise price was $40.0 million. As a result, WESCO recorded a pre-tax impairment loss of $3.4 million to selling, general and administrative expenses during the first quarter of 2010. On June 7, 2010, WESCO completed the sale of its 40% interest in the LADD joint venture and recorded an additional impairment charge of $0.4 million to selling, general and administrative expenses. WESCO received $40.0 million for its 40% interest plus $15.0 million for the outstanding promissory note and $0.5 million for accrued interest. </div> </div>

EMPLOYEE BENEFIT PLANS</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     A majority of WESCO’s employees are covered by defined contribution retirement savings plans for their services 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. For the six months ended June 30, 2010 and 2009, WESCO incurred charges of $11.0 million and $5.0 million, respectively, for all such plans. Effective January 1, 2010, WESCO reinstated all discretionary contributions that had been suspended since August 1, 2009 with the exception of a certain group of employees comprised of corporate officers and others. Reinstatement for these employees will be contingent upon WESCO reaching certain financial objectives. Contributions are made in cash to all employee retirement savings plan accounts, except for the deferred compensation plan. Employees then have the option to transfer balances allocated to their accounts into any of the available investment options, including WESCO common stock. </div> </div>

WESCO’s three and six month effective tax rates are lower than the federal statutory rate of 35% primarily due to benefits resulting from the recapitalization of Canadian operations, which are partially offset by nondeductible expenses, state taxes and foreign rate differences. The effective tax rate for the six months ended June 30, 2010 reflects discrete adjustments totaling $1.2 million related to changes in uncertain tax positions and discrete adjustments totaling $0.5 million associated with prior years’ taxes.

During the next twelve months, it is reasonably possible that the amount of unrecognized tax benefits will decrease by $1.4 million due to the resolution of federal, state and foreign tax examinations. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     WESCO records interest related to uncertain tax positions as a part of interest expense in the consolidated statement of income. As of June 30, 2010 and December 31, 2009, WESCO had an accrued liability for interest related to uncertain tax positions of $4.8 million and $4.5 million, respectively. Penalties are recognized as part of income tax expense. There were no penalties recorded during the six months ended June 30, 2010. </div> </div>
