The sum of basic and diluted earnings per share for each of the quarters may not equal the total basic and diluted earnings per share for the annual periods because of rounding differences and a difference in the way that in-the-money stock options are considered from quarter to quarter. 

⁽¹⁾  Our fourth quarter 2017 Net income and Net income attributable to Pool Corporation reflects benefits recorded due to U.S. tax reform. For additional information related to the impact of U.S. tax reform on our financial statements, see Note 7.
