Report of Independent Registered Public Accounting Firm

To the Participants and Administrator

WESCO Distribution, Inc. Retirement Savings Plan

Pittsburgh, Pennsylvania

We have audited the accompanying statements of net assets available for benefits of the WESCO Distribution, Inc. Retirement Savings Plan (the “Plan”) as of December 31, 2014 and 2013, and December 29, 2013, and the related statements of changes in net assets available for benefits for the year ended December 31, 2014 and the period from December 30, 2013 to December 31, 2013. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes 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, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2014 and 2013, and December 29, 2013, and the changes in net assets available for benefits for the year ended December 31, 2014 and the period from December 30, 2013 to December 31, 2013, in conformity with accounting principles generally accepted in the United States of America.

The accompanying supplemental schedules of assets (held at end of year) as of December 31, 2014 and 2013 have been subjected to audit procedures performed in conjunction with the audits of the Plan’s financial statements. The supplemental schedules are the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental schedules reconcile to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental schedules. In forming our opinion on the supplemental schedules, we evaluated whether the supplemental schedules, including their form and content, are presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental schedules are fairly stated, in all material respects, in relation to the financial statements as a whole.

1.	Major Features of the Plan

Background

WESCO Distribution, Inc. Retirement Savings Plan (the “Plan”) was established as of February 28, 1994 (date of inception). At the date of inception, certain employees of the predecessor company became employees of WESCO Distribution, Inc. (the “Company”) and participants in the Plan. At the date of inception, all funds held by the prior plans of the predecessor company related to the employees of the Company were transferred to the Plan.

The Plan is a participant-directed defined contribution plan covering certain employees of the Company and former employees with a fund balance of at least $5,000 who elected to maintain their funds in the Plan. Former employees cannot make contributions to the Plan.

Participation for eligible employees requires an employee to be scheduled to work at least 1,000 hours per year and requires an employee to be paid through the Plan sponsor's payroll system.

Amendment to Plan Year

On August 23, 2013, the Plan’s Administrative and Investment Committee executed the sixth amendment to the Plan (the “Sixth Amendment”). Pursuant to the terms of the Sixth Amendment, the plan year was changed, effective December 30, 2013, to the consecutive 12 month period beginning January 1 and ending on December 31 of each calendar year. The two-day period beginning on December 30, 2013 and ending on December 31, 2013 is referred to throughout these financial statements and notes thereto as the "short plan year."

Contributions

The Plan is subject to the Employee Retirement Income Security Act of 1974, as amended (“ERISA”). Participants may elect to make tax deferred contributions ranging from 1% up to the lesser of 50% of their eligible compensation or $17,500 for 2014 and 2013. The $17,500 limit may be adjusted in future years by the Internal Revenue Service (“IRS”). The sum of the tax deferred contributions and the after-tax contributions cannot exceed 50% of the participant's eligible compensation. Subject to limitation, the Company will make matching contributions in an amount equal to 50% of a participant's total monthly contributions up to a maximum of 3% of their compensation. Also, the Company may, at the Board of Directors' discretion, make a discretionary contribution to the Plan provided certain predetermined profit levels are attained. Discretionary contributions of approximately $10,209,000 were made for the Plan's year ended December 31, 2014. The Company made no discretionary contributions for the short plan year ended December 31, 2013.

Participants may rollover into the Plan amounts representing distributions from other qualified retirement plans, an individual retirement account or an annuity. For the year ended December 31, 2014 and the short plan year ended December 31, 2013, the Plan accepted employee rollover contributions of approximately $1,886,000 and $17,000, respectively.

The Plan includes a negative enrollment policy. Under this policy, if an individual does not submit an automatic enrollment waiver or elect a deferral rate, the employee will be automatically enrolled in the Plan at a 3% deferral rate. The deferral rate is increased by 1% each September 1 until the deferral rate equals 6%.

Participants who have attained age 50 before the close of the plan year are eligible to make catch-up contributions in addition to pre-tax contributions. A catch-up contribution is a pre-tax contribution that exceeds the annual deferral limit. For 2014 and 2013, a participant's total catch-up contribution could not exceed $5,500. The catch up contribution limits are determined by the IRS and then indexed for inflation. In addition to cash, in-kind contributions are permitted which may consist of stocks, bonds, property or other securities.

Notes to Financial Statements

December 31, 2014 and 2013, and December 29, 2013

Vesting

Participants are fully vested in the value of their contributions and related investment income at all times and vest in their allocated share of employer matching and discretionary contributions according to the following table:



Less than two years of service	0	%
Two years of service	20	%
Three years of service	40	%
Four years of service	66	%
Five or more years of service	100	%

In conjunction with a leveraged recapitalization of the Company, all active employees as of June 5, 1998 became fully vested.

Distributions

A participant may not withdraw any amount from their vested account balance unless they are age 59½, retire, become deceased or disabled, terminate employment, or experience financial hardship.

A participant who qualifies for a hardship withdrawal is suspended from making contributions to the Plan for six months. Under present IRS rules, a “hardship” means an immediate and heavy need to draw on financial resources to meet obligations related to health, education, housing, or death of a family member.

A participant, upon termination of service, may either receive a lump-sum payment of their vested account balance or transfer their balance to the trustee or custodian of another eligible retirement plan.

Forfeitures

Employer contributions forfeited by participants not vested at their termination date are used to reinstate previously forfeited account balances of former participants who have returned to the Company, reduce employer contributions in accordance with the Plan's provisions or pay Plan expenses. Total forfeitures that reduced employer contributions in 2014 were approximately $1,179,000. There were no forfeitures during the short plan year ended December 31, 2013. As of December 31, 2014, a balance of approximately $356,000 was available to reduce employer contributions in 2015.

Participant Accounts

An account is maintained for each participant, which is credited with the participant's and the employer's matching contributions and an allocation of employer's discretionary contributions, and plan earnings and charged with benefit payments and an allocation of plan losses and administrative expenses. Allocations are based on participant contributions or account balances, as defined by the Plan. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account balance.

Promissory Notes from Participants

Participants are permitted to borrow against a portion of their vested account balance, pursuant to nondiscriminatory rules established by the Administrative and Investment Committee, up to a maximum of $50,000 or 50% of their vested account balance. Each loan is to be repaid over a period not to exceed five years.

Plan Termination

Although the Company has not expressed any intent to do so, it has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event the Plan terminates, participants will become 100% vested in their accounts, and all vested assets shall be distributed to the participants in accordance with the terms of the Plan, or in such other manner, not inconsistent with the requirements of any applicable law or regulation, as the Company may in its sole discretion determine.


2.	Summary of Significant Accounting Policies

Accounting Principles

The financial statements of the Plan have been prepared in accordance with accounting principles generally accepted in the United States of America. The following are the significant accounting policies followed by the Plan:

Basis of Accounting

The accounting records of the Plan are maintained on the accrual basis of accounting.

Reclassifications

The Statement of Net Assets Available for Benefits and Note 4 as of December 29, 2013 include certain reclassifications to previously reported amounts to conform to the current period presentation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make significant estimates and assumptions. These estimates may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements. Actual results could differ from those estimates.

Investment Valuation and Income Recognition

The Plan has adopted a framework for measuring fair value under current accounting pronouncements that requires fair value measurements and enhanced disclosures about fair value measurements. This framework defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction. Disclosures include a fair value hierarchy that requires an entity to maximize the use of observable inputs when measuring fair value.

The three levels of inputs that may be used to measure fair value are as follows:


•	Level 1 - Observable inputs such as quoted prices in active markets for identical investments that the Plan has the ability to access.


•	Level 2 - Inputs include:


1.	Quoted prices for similar assets or liabilities in active markets;


2.	Quoted prices for identical or similar assets or liabilities in inactive markets;


3.	Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and


4.	Inputs that are derived principally from, or corroborated by, observable market data by correlation or other means.

WESCO Distribution, Inc.

Retirement Savings Plan

Notes to Financial Statements

December 31, 2014 and 2013, and December 29, 2013


•	Level 3 - Unobservable inputs in which there is little or no market activity for the asset or liability, which require the reporting entity to develop its own estimates and assumptions relating to the pricing of the asset or liability, including assumptions regarding risk.

The asset's or liability's fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in the methodologies used as of December 31, 2014 and 2013, and December 29, 2013.

•

Common stocks are valued at the closing price reported on the active market on which the individual securities are traded. Common stocks include the WESCO International Pooled Stock Fund, which is an employer stock unitized fund. Such fund consists of WESCO International, Inc. common stock and a short-term cash component, which provides liquidity for daily trading. WESCO International, Inc. common stock is valued at the quoted closing market price from a national securities exchange and the short term cash investments are valued at cost, which approximates fair value.


•	Registered investment companies are valued at the net asset value of shares held by the Plan as of December 31, 2014 and 2013, and December 29, 2013.


•	The Stable Value Fund (Note 5) is valued based on the underlying securities, which include corporate bonds, commercial mortgage-backed securities and government securities.


•	The RAFI Enhanced Large Company Fund is valued at net asset value based on the value of the underlying securities, which primarily include common stocks. The fund seeks to provide growth through exposure to a broad class of securities. There are no unfunded commitments or restrictions on participant redemptions.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Plan believes its valuation methods are 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 as of the reporting date.

Investment contracts held by a defined-contribution plan are required to be reported at fair value. However, contract value is the relevant measurement for that portion of the net assets available for benefits of a defined-contribution plan attributable to fully benefit-responsive investment contracts, because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the plan. As required by accounting principles generally accepted in the United States of America, the statements of net assets available for benefits present the fair value of the investment contracts as well as the adjustment of the fully benefit-responsive investment contracts from fair value to contract value. The statements of changes in net assets available for benefits are prepared on a contract value basis.

Purchases and sales of securities are recorded on a trade date basis. Dividends are recorded on the ex-dividend date. Interest income is recorded on an accrual basis.

WESCO Distribution, Inc.

Retirement Savings Plan

Notes to Financial Statements

December 31, 2014 and 2013, and December 29, 2013

Net Appreciation in Value of Investments

The Plan presents in the statements of changes in net assets available for benefits the net appreciation (depreciation) in the fair value of its investments, consisting of realized gains (losses) and unrealized gains (losses) in the registered investment companies, Stable Value Fund, RAFI Enhanced Large Company Fund, WESCO International stock and other common stocks.

Risks and Uncertainties

The Plan provides for various investment options in any combination of stocks, bonds, fixed income securities and other investment securities. Investment securities are exposed to various risks, such as interest rate, market and credit risk. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in the near-term could materially affect (i) participants' account balances, and (ii) the amounts reported in the (a) statements of net assets available for benefits and the (b) statements of changes in net assets available for benefits.

Payment of Benefits

Benefits are recorded when paid.

Recently Issued Accounting Pronouncments

In May 2015, the Financial Accounting Standards Board (FASB) issued updated guidance to remove the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value (NAV) per share practical expedient. The practical expedient criteria differ from the criteria used to categorize other fair value measurements within the hierarchy. Currently, investments valued using the practical expedient are categorized within the fair value hierarchy on the basis of whether the investment is redeemable with the investee at NAV on the measurement date, never redeemable with the investee at NAV, or redeemable with the investee at NAV at a future date. Under this updated guidance, investments for which fair value is measured at NAV per share (or its equivalent) using the practical expedient should not be categorized in the fair value hierarchy. A reporting entity should continue to disclose information on investments for which fair value is measured at net asset value (or its equivalent) as a practical expedient to help users understand the nature and risks of the investments and whether the investments, if sold, are probable of being sold at amounts different from net asset value. The guidance is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years, and should be applied retrospectively. The retrospective approach requires that an investment for which fair value is measured using the net asset value per share practical expedient be removed from the fair value hierarchy in all periods presented in an entity’s financial statements. Earlier application is permitted. The Plan's management has not yet evaluated the future impact of this guidance on the Plan's financial statements and notes thereto.

Other

All administrative expenses were paid by the Plan during the year ended December 31, 2014 and the short plan year ended December 31, 2013.


3.	Tax Status

The IRS has determined and informed the Company by a letter dated November 15, 2012, that the Plan is designed in accordance with Section 401(a) of the Internal Revenue Code (“IRC”) and, therefore, is exempt from federal taxes under provisions of Section 501(a). Accordingly, no provision for income taxes has been included in the Plan's financial statements. The Plan has been amended since receiving its determination letter. However, the Plan administrator and the Plan's tax counsel believe the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC.

Accounting principles generally accepted in the United States of America require plan management to evaluate tax positions taken by the plan and recognize a tax liability (or asset) if the plan has taken an uncertain position that more likely than not

would not be sustained upon examination by a taxing authority. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The plan administrator believes it is no longer subject to income tax examinations for years prior to 2011.

* The Plan did not hold an investment in this fund as of the respective reporting date.


5.	The Stable Value Fund

During 2007, the Plan began investing in a fully benefit-responsive synthetic guaranteed interest contract (“GIC”) with an insurance company as part of offering the Stable Value Fund (the “Fund”) investment option to participants. Contributions to this Fund are used to purchase units of a collective trust vehicle that is invested in high-quality U.S. bonds, including U.S. government treasuries, corporate debt securities, and other high-credit-quality asset-backed securities. The GIC issuer is contractually obligated to repay the principal and a specified interest rate that is guaranteed to the Plan. There are no reserves against contract value for credit risk of the contract issuer or otherwise.

The Fund has entered into a wrap contract with an insurance company under which the insurance company provides a guarantee with respect to the availability of funds to make distributions from this investment option. This insurance contract is carried at contract value in the participants' accounts.

Participant accounts in the Fund are credited with interest at a fixed rate that is reset quarterly based on an agreed-upon formula as defined in the contract. The primary variables that could impact the future interest rates that are credited to the participant's accounts (“credited rates”) include (i) the amount and timing of participant contributions, (ii) transfers and withdrawals into/out of the contract, (iii) the current yield of the assets underlying the contract, (iv) the duration of the assets underlying the contract, and (v) the existing difference between fair value of the securities and the contract value of the assets within the insurance contract. The credited rate of security-backed contracts will track current market yields on a trailing basis. The rate reset feature allows the contract value to converge with the fair value of the underlying portfolio over time, assuming the portfolio continues to earn the current yield for a period of time equal to the current portfolio duration.

To the extent that the underlying portfolio has unrealized and/or realized losses, a positive adjustment is made when reconciling from fair value to contract value under contract value accounting. As a result, the future credited rate may be lower over time than the current market rates. Similarly, if the underlying portfolio generates unrealized and/or realized gains, a negative adjustment is made when reconciling from fair value to contract value, and in the future, the credited rate may be higher than the current market rates. The insurance contract cannot credit an interest rate that is less than zero percent.

Certain events limit the ability of the Plan to transact at contract value with the insurance company. Such events are limited to premature termination of the contract by the Plan or plan termination. The plan sponsor has not expressed any intention to take either of these actions.

As described in Note 2, because the synthetic GIC is fully benefit-responsive, contract value is the relevant measurement attribute for that portion of the net assets available for benefits attributable to the synthetic GICs. Participants may ordinarily direct the withdrawal or transfer of all or a portion of their investment at contract value.

Notes to Financial Statements

December 31, 2014 and 2013, and December 29, 2013

The average yields earned by the Fund are as follows:



	December 31,		December 29,
Average yield for synthetic GICs	2014	2013	2013
Based on actual earnings	1.91%	2.05%	2.05%
Based on interest rate credited to participants	2.32%	2.36%	2.35%


6.	Promissory Notes From Participants

The interest rate applied to participant loans is established each month by the Administrative and Investment Committee at 1% above the prime interest rate. The interest rate on loans outstanding ranged between 4.25% and 9.25% for the year ended December 31, 2014 and the short plan year ended December 31, 2013. Principal and interest payments are generally made through monthly payroll deductions and are credited to the participant's individual account. Loans of approximately $7,787,000 were made from the Plan and loan principal repayments of approximately $7,253,000 were received by the Plan during the year ended December 31, 2014. Loans of approximately $70,000 were made from the Plan during the short plan year ended December 31, 2013. The Plan did not receive any loan principal repayments during the short plan year ended December 31, 2013. Interest on the promissory notes of approximately $587,000 was earned by the Plan for the year ended December 31, 2014. The Plan did not accrue any interest on the promissory notes during the short plan year ended December 31, 2013.


7.	Party-In-Interest

Participants of the Plan may elect to invest in WESCO International, Inc. common stock within the WESCO Pooled Stock Fund. WESCO International, Inc. owns 100% of the Company. Therefore, these transactions qualify as party-in-interest transactions. Purchases and sales proceeds within the WESCO Pooled Stock Fund for the year ended December 31, 2014 were approximately $3,470,000 and $4,286,000, respectively, and purchases and sales proceeds for the short plan year ended December 31, 2013 were approximately $3,000 and $1,000, respectively.


8.	Plan Transfers

On June 18, 2014, the Plan's Administrative and Investment Committee executed the eighth amendment to the Plan (the "Eighth Amendment") to merge the Talcup, Inc. Employee Savings Plan Local 243 (the "Talcup Union Plan") into the WESCO Distribution, Inc. Retirement Savings Plan. The participants in the Talcup Union Plan were certain employees of RS Electronics. The Company, through a wholly-owned subsidiary, acquired RS Electronics on January 3, 2012. Effective August 1, 2014, participants in the Talcup Union Plan became participants in the WESCO Distribution, Inc. Retirement Savings Plan. Talcup Union Plan assets of approximately $100,000 were transfered into the WESCO Distribution, Inc. Retirement Savings Plan on such date. The terms of the Eighth Amendment provide that eligible employees who were transferred to the Plan received vesting service credit for their service under the Talcup Union Plan prior to the transfer and employees whose accounts are merged into the Plan shall be fully vested in such transferred accounts and in their new accounts under the Plan.

The Company acquired Hi-Line Utility Supply ("Hi-Line") on June 11, 2014. As a result of this acquisition, approximately 30 employees were accepted into the Plan. Such employees did not rollover any amounts from the retirement savings plan maintained by Hi-Line's plan administrator into the Plan during the year ended December 31, 2014.


9.	Subsequent Event

The plan sponsor evaluated subsequent events and transactions for potential recognition or disclosure in the financial statements through June 29, 2015, the day the financial statements were approved and authorized for issue, and concluded that all events that would require recognition or disclosure are appropriately reflected in these financial statements.
