Basic and diluted net income per share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. The number of diluted shares reflects the potential dilution that could occur if holders of in-the-money options and warrants were to exercise their right to convert these instruments into common stock and unvested restricted stock units (“RSUs”) were to vest. Additionally, performance-based RSUs are considered contingent shares; therefore, at each reporting date we determine the probable number of shares that will vest and include these contingently issuable shares in our diluted share calculation unless they are anti-dilutive. Once these performance-based RSUs vest, they are included in our basic net income per share calculation.

The following table presents a reconciliation of basic and diluted net income per share, including the number of dilutive equity awards included in the dilutive net income per share computation (in thousands):
