(a)

For the nine months ended September 30, 2011, the federal and state current tax expense (benefit) of zero and ($0.1) million, respectively, (zero and $0.1 million for the quarter ended September 30, 2011) is due to a net operating loss (NOL) which resulted primarily from the bonus depreciation provision of the Small Business Jobs Act of 2010. The 2011 federal and state NOL will be carried forward to offset future taxable income. For the quarter and nine months ended September 30, 2010, we recorded a federal current tax benefit as a result of tax planning initiatives and the bonus depreciation provision in the Small Business Jobs Act of 2010. The 2010 federal NOL was partially utilized by carrying it back against prior years’ income with the remainder carried forward to offset future years’ income.

(b)

The nine months ended September 30, 2011, includes a second quarter income tax benefit of $2.9 million related to the MPUC approval of our request to defer the retail portion of the tax charge taken in 2010 as a result of PPACA and a first quarter benefit for the reversal of a $6.2 million deferred tax liability related to a revenue receivable that Minnesota Power agreed to forgo as part of a stipulation and settlement agreement in its 2010 rate case. Included in the nine months ended September 30, 2010, is a first quarter charge of $4.0 million as a result of PPACA. (See Note 6. Regulatory Matters.)
