Amounts are as reported in the Company’s financial statements in accordance with
generally accepted accounting principles or any other accounting reporting
system under which the Company is required to report its financial statements
(subject to possible exclusions as described below).

 
“EPS Growth” means the three-year average growth rate of the Company’s fully
diluted earnings per share (i.e. diluted earnings per share attributable to
WESCO International, Inc.), as reported in the Company’s financial statements in
accordance with generally accepted accounting principles or any other accounting
reporting system under which the Company is required to report its financial
statements (subject to possible exclusions as described below). The methodology
for calculating the three-year average EPS Growth rate is as follows:
[[20__ EPS – 20__ EPS]/20__ EPS] x 100 = Year 1 Growth Rate %
[[20__ EPS – 20__ EPS]/20__ EPS] x 100 = Year 2 Growth Rate %
[[20__ EPS – 20__ EPS]/20__ EPS] x 100 = Year 3 Growth Rate %

[Year 1 Growth Rate % + Year 2 Growth Rate % + Year 3 Growth Rate %]/3 =
three-year average EPS Growth rate

In calculating RONA and EPS Growth, the Committee may exclude certain items that
are not indicative of ongoing results. Examples of items that may be excluded
from calculating RONA and EPS Growth include, but are not limited to:
“strategic” items (investments, charges or credits related to the high-level
strategic direction of the Company, such as restructurings, acquisitions,
divestitures, the purchase or sale of equities, and the issuance or payment of
debt); “regulatory” items (charges or credits due to changes in tax or
accounting rules); “external” items (charges or credits due to external events
such as natural disasters); and “other” significant unusual, nonrecurring or
rare items (such as charges or credits due to litigation or legal settlements,
the disposal of assets or asset impairment).

The Committee shall adjust the Award to reflect a change in corporate
capitalization, such as a stock split or dividend, or a corporate transaction,
such as any merger of a corporation into another corporation, any consolidation
of two or more corporations into another corporation, any separation of the
Company or a Subsidiary (including a spinoff or other distribution of stock or
property by a corporation), any reorganization of the Company or its
Subsidiaries (whether or not such reorganization comes within the definition of
such term in Code Section 368), or any partial or complete liquidation by the
Company or its Subsidiaries.
