Earnings (Loss) Per Share

3 Months Ended

Mar. 31, 2020

Basic earnings (loss) per share is computed by dividing the earnings (loss) attributable to Oasis common stockholders by the weighted average number of shares outstanding for the periods presented. The calculation of diluted earnings (loss) per share includes the potential dilutive impact of unvested restricted stock awards and contingently issuable shares related to PSUs and the Senior Convertible Notes during the periods presented, unless its effect is anti-dilutive. There are no adjustments made to the income (loss) attributable to Oasis available to common stockholders in the calculation of diluted earnings (loss) per share.

The following is a calculation of the basic and diluted weighted average shares outstanding for the three months ended March 31, 2020 and 2019:


	Three Months Ended March 31,
	2020	2019

	(In thousands)
Basic and diluted weighted average common shares outstanding	316,828	314,464

For the three months ended March 31, 2020 and 2019, the Company incurred a net loss, and therefore the diluted loss per share calculation for those periods excludes the anti-dilutive effect of unvested stock awards. The following is a calculation of weighted average common shares excluded from diluted loss per share due to the anti-dilutive effect:


	Three Months Ended March 31,
	2020	2019

	(In thousands)
Restricted stock awards and PSUs	11,166	9,800

The Company has the option to settle conversions of its Senior Convertible Notes (see Note 10 — Long-Term Debt) with cash, shares of common stock or a combination of cash and common stock at its election. The Company’s intent is to settle the principal amount of the Senior Convertible Notes in cash upon conversion. As a result, only the amount by which the conversion value exceeds the aggregate principal amount of the notes (conversion spread) is considered in the diluted earnings per share computation under the treasury stock method. As of March 31, 2020 and 2019, the conversion value did not exceed the principal amount of the notes, and accordingly, there was no impact to diluted loss per share for the three months ended March 31, 2020 and 2019.
