NOTE 10. INCOME PER SHARE AND PARTNERSHIP UNIT

Income per share and unit has been computed using the two-class method, which is computed by dividing the sum of distributed earnings to common stockholders and undistributed earnings allocated to common stockholders by the weighted average number of shares of common stock outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both shares of common stock and participating securities based on the weighted average shares outstanding during the period. Classification of the Company's unvested restricted stock, which contain rights to receive nonforfeitable dividends, are deemed participating securities under the two-class method. Under the two-class method, earnings attributable to unvested restricted shares are deducted from income from continuing operations in the computation of net income attributable to common stockholders.

The table below is a reconciliation of the numerator and denominator used in the computation of basic and diluted net (loss) income per share and unit computed using the two-class method (dollars in thousands):

The Corporation intends to satisfy its exchange obligation for the principal amount of the 2021 Convertible Notes to the note holders entirely in cash; therefore, the "if-converted" method does not apply and the treasury stock method is being used. For the nine months ended September 30, 2020 and 2019, the Corporation’s average stock price was below the conversion price, resulting in zero potentially dilutive shares related to the conversion spread of the 2021 Convertible Notes.
