Note 5 – Income Taxes

Income tax expense was $6,182,000 for the first quarter in 2013 as compared to $6,035,000 for the same period in 2012. Our effective tax rates on pretax income were 25.0% and 25.4% for the first quarter of 2013 and 2012, respectively. The effective tax rates differ from the statutory federal tax rate of 35% largely due to tax exempt interest income earned on certain investment securities and loans, the deductibility of dividends paid to our employee stock ownership plan and Texas state taxes.
