Item 2.02 Results of Operations and Financial Condition

On February 20, 2006, UIL Holdings Corporation (the Registrant) issued a press release that announces the Registrant's financial results for the three and twelve months ended December 31, 2006 and provides 2007 earnings guidance. A copy of the Registrant's press release is attached hereto as Exhibit 99. The information in this Form 8-K shall not be deemed to be "filed" for the purposes of Section 18 of the Securities and Exchange Act of 1934 (the "Exchange Act"), or otherwise subject to the liabilities of such section, nor shall such information be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

Use of Non-GAAP Measures

UIL Holdings believes earnings per share (EPS) information is useful in understanding the fluctuations in EPS between the current and prior periods. The amounts presented show the EPS from continuing operations and discontinued operations where applicable for each of UIL Holdings’ lines of business. Continuing Operations is further displayed for clarity by continuing operations and divested minority owned businesses on an EPS basis. EPS is calculated by dividing the income from continuing operations, divested minority owned businesses and discontinued operations for each line of business by the average number of shares of UIL Holdings common stock outstanding for the periods presented. The EPS for all periods presented are calculated on the same basis and reconcile to the amounts presented on a generally accepted accounting principle’s (GAAP) basis. The earnings per share for each of continuing operations, discontinued operations and combined total EPS is a GAAP basis presentation.

UIL Holdings also believes that a breakdown, presented on a per share basis, of how particular significant items contributed to the change in income from continuing operations, divested minority owned businesses and discontinued operations by line of business (Item Variance EPS Presentation) is useful in understanding the overall change in the consolidated results of operations for UIL Holdings from one reporting period to another. UIL Holdings presents such per share amounts by taking the dollar amount of the applicable change for the revenue or expense item, booked in accordance with GAAP, and applying UIL Holdings’ combined effective statutory federal and state tax rate. Any amounts provided as Item Variance EPS Presentation are provided for informational purposes only and are not intended to be used to calculate “Pro-forma” amounts.
