The Company reports both basic and diluted loss per share, which is based on the weighted average number of common shares outstanding during the period.

A reconciliation of the numerator and denominator used in the calculation of basic and diluted net loss per common share follows (in thousands):

	Three Months Ended March 31,						Nine Months Ended March 31,
	2019			2018			2019			2018
Numerator:
Net loss used to compute basic and diluted loss per share	$	(1,184	)	$	(8,852	)	$	(15,030	)	$	(22,953	)
Denominator:
Weighted average shares used to compute basic and diluted loss per share		87,962			85,459			87,220			84,594

The potentially dilutive shares of the Company’s common stock resulting from the assumed exercise of outstanding stock options, the settlement of vested Restricted Stock Units (“RSUs”), Market Stock Units (“MSUs”) and Performance Stock Units (“PSUs”), and the purchase of shares under the Company’s Employee Stock Purchase Program (“ESPP”), as determined under the treasury stock method, are excluded from the computation of diluted net loss per share because their effect would have been anti-dilutive. Additionally, the 3.50% Convertible Notes are included in the calculation of diluted net income per share only if their inclusion is dilutive.

The following table sets forth all potentially dilutive securities excluded from the computation in the table above because their effect would have been anti-dilutive (in thousands):

	As of March 31,
	2019		2018
Stock options		5,199		2,672
RSUs, PSUs and MSUs		3,744		5,202
		8,943		7,874

The 3.75% Convertible Notes have, and the 3.50% Series A Convertible Notes had, an optional physical (share), cash or combination settlement feature and contain certain conditional conversion features. The 3.50% Series A Convertible Notes were retired in February 2018. Due to the optional cash settlement feature and management’s intent to settle the principal amount thereof in cash, the shares of our common stock issuable upon conversion of the outstanding principal amount of the 3.75% Convertible Notes as of March 31, 2019 and 2018, totaling approximately 14.9 million shares of our common stock, were not included in the basic and diluted net loss per common share table above.
