business. We evaluated the materiality of the error from qualitative and quantitative perspectives and concluded it was not material to any prior periods. The correction of the error in the third quarter of 2009 could be considered material to the results of operations for the three months ended September 30, 2009, but is not material to the results of operations for the nine months ended September 30, 2009. Accordingly, we made an adjustment in the third quarter of 2009 that resulted in a decrease in DPAC amortization expense. On an after-tax basis, the adjustment for prior periods resulted in an $18.9 million increase in net income for the three months ended September 30, 2009. </dd></dl></div></td></tr></table> 20.
