EARNINGS AND DIVIDENDS PER COMMON SHARE

The weighted average number of common shares outstanding during the reporting period is used to calculate basic earnings per common share. Diluted earnings per common share assume the exercise of stock options and vesting of restricted shares using the treasury stock method, to the extent dilutive. Dilution resulting from the conversion option within our convertible debt is determined by computing an average of incremental shares included in each quarterly diluted EPS computation. If NHI’s current share price increases above the adjusted conversion price, further dilution will be attributable to the conversion feature.

The following table summarizes the average number of common shares and the net income used in the calculation of basic and diluted earnings per common share (in thousands, except share and per share amounts):
