Gartner expects the acquisition of Burton Group to be accretive to its revenue, earnings and cash flow over time. On a reported GAAP basis, the transaction is expected to be dilutive to income per share by ($0.12) " ($0.10) in 2010 and accretive to income per share by at least $0.00 " $0.03 in 2011. Excluding estimated acquisition and integration related charges, the transaction is expected to be modestly accretive to income per share in 2010 and add at least $0.04 " $0.06 to income per share in 2011.

Non-GAAP Financial Measures

Investors are cautioned that income per share, excluding estimated acquisition and integration related charges is not a financial measure under generally accepted accounting principles (GAAP). In addition, it should not be construed as an alternative to any other measures of performance determined in accordance with GAAP. This non-GAAP financial measure is provided to enhance the user's overall understanding of the expected impact of the acquisition of Burton Group on Gartner's future operating results. We believe that income per share, excluding estimated acquisition and integration related charges, is an important measure of the expected benefits from the acquisition of Burton Group as it excludes charges that may not be indicative of Gartner's core ongoing operating results.

The following is a reconciliation of the expected impact of the acquisition of Burton Group on income per share, excluding estimated acquisition and integration related charges, to GAAP income per share:

2010 2011

Expected impact on GAAP income per share ($0.12) " ($0.10) $0.00 " $0.03
