(26) Quarterly Financial Information (Unaudited) The following is a summary of quarterly financial data: (1) Net income per share (“EPS”) in each quarter is computed using the weighted-average number of shares outstanding during that quarter, while EPS for the full year is computed using the weighted-average number of shares outstanding during the year. Thus, the sum of the four quarters EPS does not necessarily equal the full-year EPS. (2) Basic shares outstanding includes shares held in a grantor trust. On February 21, 2019, the Company announced that its Board of Directors approved a 3-for-2 common stock split to be paid in the form of a stock dividend to holders of record on March 14, 2019.
