The calculation of diluted net income per share for the three month period ended March 31, 2018 includes the impact of the Company’s convertible senior notes as the average stock price of the Company’s common stock during the period was above the initial conversion price of approximately $11.70 per share. The convertible notes matured in May 2018, so there were no dilutive shares in 2019.
