Income Taxes	Income Taxes Our effective tax rate resulted in an expense of 29.0% on income in the second quarter of 2013 as compared to 32.5% in the second quarter of 2012. On a year to date basis, the effective tax rate was 29.1% for the first six months of 2013 as compared to 5.0% in the first six months of 2012. In the first six months of 2012, our tax rate was favorably impacted by certain one-time discrete items including a $1.5 million benefit related to the reversal of the valuation allowance resulting from the liquidation of the auction rate securities portfolio.
