Earnings per Share

Basic income per share is calculated by dividing net income attributable to Del Taco’s common shareholders for the period by the weighted average number of common shares outstanding for the period. In computing dilutive income per share, basic income per share is adjusted for the assumed issuance of all applicable potentially dilutive share-based awards, including warrants, restricted stock, common stock options and restricted stock units.

Below are basic and diluted net income per share for the periods indicated (amounts in thousands except share and per share data):
