Non-GAAP Diluted Earnings Per Share

The company provides non-GAAP financial measures to assist stockholders with the analysis of financial and business trends related to the company’s operations. These calculations are not in accordance with, or an alternative for, generally accepted accounting principles (GAAP) and may be different from non-GAAP measures presented by other companies.

Non-GAAP diluted earnings per share applicable to common stockholders in the third quarter of 2008 were $0.33, compared to $0.24 per diluted share in the comparable period last year on a non-GAAP basis. Non-GAAP diluted earnings per share applicable to common stockholders for the nine months ended September 30, 2008 were $0.54, compared to $0.56 per diluted share in the comparable period in 2007 on a non-GAAP basis. Non-GAAP diluted earnings per share excludes stock option expense, the effect of the intellectual property settlement, net of the impact of taxes applicable to the settlement, external expenses related to the company’s proposed merger agreement and the net effect of contract revenue and contract expense. Contract revenue is the result of the recognition of certain revenue that was carried on i2’s balance sheet as a portion of deferred revenue and was a result of the company’s 2003 financial restatement. As of March 31, 2007, the deferred contract revenue balance was zero.

A full reconciliation of GAAP to non-GAAP financial measures can be found in Schedule A included with this release.
