INCOME TAXES
INCOME TAXES	NOTE K — INCOME TAXES We recorded a benefit from income tax of $3.7 million and $6.2 million for the three months ended March 31, 2019 and 2018, respectively. The effective tax rate was 35.0% and 21.5% for the three months ended March 31, 2019 and 2018, respectively. The increase in the effective tax rate for the three months ended March 31, 2019 compared with the three months ended March 31, 2018 is primarily attributable to the change from the discrete method in the three months ended March 31, 2018 to the annual effective tax rate for the three months ended March 31, 2019, an increased estimated annual income, and the windfall from stock-based compensation recorded as a discrete item during the period. Our effective tax rate for the three months ended March 31, 2019 differed from the federal statutory tax rate of 21% primarily due to non-deductible expenses and the windfall from stock-based compensation recorded as a discrete item during the period. Our effective tax rate for the three months ended March 31, 2018 differed from the federal statutory tax rate of 21% primarily due to non-deductible expenses and the shortfall from stock-based compensation recorded as a discrete item during the period.
