Diluted	$	0.04	$	0.03	$	0.23	$	0.04

We excluded the following weighted-average potential shares from the calculations of diluted net income per share during the applicable periods because their inclusion would have been anti-dilutive:



	Third Quarter		First Nine Months
(In thousands)	2018	2017	2018	2017
Stock options and restricted stock awards	735	1,693	1,184	2,149
2017 Convertible Notes	—	7,569	—	7,569

The unsecured convertible senior notes due 2017 (“2017 Convertible Notes”) were repaid upon maturity in October 2017. The 2021 Convertible Notes (as defined in Note 7) only impact the calculation of diluted net income per share in periods that 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. 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 7. 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 per share.
