NOTE 9: Income Taxes

For the first quarter of 2012, the Corporation recognized income tax expense of $21 million, compared to income tax expense of $8 million for the first quarter of 2011. The effective tax rate was 32.70% for the first quarterof 2012, compared to an effective tax rate of 25.63% for the first quarter of 2011. The change in income tax expense and the effective tax rate was primarily due to the level of pretax income between the comparable first quarter periods. Income tax expense is also impacted by ongoing federal and state income tax audits and changes in tax law.
