Throughout this “Segment Overview” section, the Company refers to changes in net sales, gross profit and selling and administrative expenses in EMEA and APAC excluding the effects of foreign currency movements. In computing these changes and percentages, the Company compares the current year amount as translated into U.S. dollars under the applicable accounting standards to the prior year amount in local currency translated into U.S. dollars utilizing the average translation rate for the current quarter.

Net of tax amounts referenced above were computed using the statutory tax rate for the taxing jurisdictions in the operating segment in which the related expenses were recorded.

UPDATED GUIDANCE

For the full year of 2012, the Company expects the global IT market to grow in the mid single digit range. The Company expects its business to grow faster than the market as the Company invests in its sales force and expands its capabilities into key markets. The Company expects diluted earnings per share for the full year of 2012 to be between $2.20 and $2.30.

This outlook reflects the following assumptions:

• An effective tax rate of 36% to 38% for 2012, up from 29.3% in 2011; and

• Diluted shares outstanding of approximately 45 million.

This outlook does not include any severance or restructuring expenses.
