The following potentially dilutive securities, prior to the use of the treasury stock method, have been excluded from the computation of diluted weighted-average shares outstanding, as they would be anti-dilutive. For the three and nine months ended September 30, 2020 and 2019, respectively, all of the Company’s options to purchase common stock and restricted stock units outstanding were assumed to be anti-dilutive as earnings attributable to common stockholders was in a loss position.


	Three and Nine Months Ended September 30,
	2020	2019
Options to purchase common stock	5,868,348	4,860,997

Restricted stock units	686,069	655,723
Performance units	70,000	79,000

The Company has the option to settle the conversion obligation for the Convertible Notes in cash, shares or any combination of the two. As the Convertible Notes are not convertible as of September 30, 2020, they are not participating securities and they will not have an impact on the calculation of basic earnings or loss per share. Based on the Company’s net loss position, there is no impact on the calculation of dilutive loss per share during the three and nine-month periods ended September 30, 2020 and 2019, respectively.
