3 SCANA CORPORATION Note (1): In the first quarter of 2010, pursuant to authorization by the Public Service Commission of South Carolina in connection with its annual review of fuel cost and rates, the Company accelerated the recognition of previously deferred state income tax credits in the amount of $17 million (thereby lowering income tax expense), and recorded an offsetting reduction of 2010’s recovery of fuel costs (electric revenue). These offsetting decreases had no effect on income available to common shareholders. Note (2): In May 2010, SCANA entered into an equity forward sales agreement.

Earlier this year, the South Carolina Supreme Court ruled that the contingency reserve of $438 million under the Base Load Review Act order could not be pre-approved as the Public Service Commission of South Carolina (PSC) had done. Instead, the Company is now required to submit costs above its base budget for approval by the PSC as they are identified to specific budget items. The Company anticipates filing within the next 30 days for an amount estimated to be between $150 million and $200 million, in 2007 dollars. The costs in question would be incurred over the course of the construction project which is scheduled to be completed in 2019. The Company still anticipates completing the project within the original budget estimate that included the contingency projection of $438 million and is simply responding to the court's decision by seeking commission approval to reclassify these costs from contingency funds to specific budget categories.
