The 2021 Convertible Notes will not impact the calculation of diluted net income per share unless the average price of our common stock, as calculated in accordance with the terms of the indenture governing the 2021 Convertible Notes, exceeds the conversion price of $9.33 per share. At December 31, 2017 the average price of our common stock was $8.80 per share. We have the option to pay cash, issue shares of common stock, or any combination thereof for the aggregate amount due upon conversion of the 2021 Convertible Notes as further described in Note 6 above. If converted, we currently intend to settle the principal amount of the notes in cash and as a result, only the amounts payable in excess of the principal amount of the notes, if any, are assumed to be settled with shares of common stock for purposes of computing diluted net income from continuing operations per share.
