Basic earnings per share includes no dilution and is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects, in periods in which they have a dilutive effect, the effect of restricted stock-based awards, common shares issuable upon exercise of stock options and warrants and shares underlying convertible notes potentially issuable upon conversion. The difference between basic and diluted weighted-average common shares results from the assumption that all dilutive stock options outstanding were exercised, and all convertible notes have been converted into common stock.

For the Current Quarter, of the total potentially dilutive shares related to restricted stock-based awards and stock options, approximately 0.4 million shares were anti-dilutive, as compared to approximately 0.3 million shares that were anti-dilutive for the Prior Year Quarter.

For the Current Quarter, approximately 0.4 million of the performance related restricted stock-based awards issued to the Company’s named executive officers were anti-dilutive as compared to none of the performance related restricted stock-based awards issued to the Company’s named executive officers that were anti-dilutive in the Prior Year Quarter.

A reconciliation of weighted average shares used in calculating basic and diluted earnings per share follows:

	For the Three Months Ended March 31,
(in thousands)	2020		2019
Basic		11,772		8,465
Effect of convertible notes subject to conversion		—		36,269
Effect of assumed vesting of dilutive shares		—		52
Diluted		11,772		44,786

In accordance with ASC 480, the Company considers its redeemable non-controlling interest in its computation of both basic and diluted earnings per share. In addition, in accordance with ASC 260, the Company considers its 5.75% Convertible Notes in its computation of diluted earnings per share. For the Current Quarter and Prior Year Quarter, adjustments to the Company’s redeemable non-controlling interest and effects of potential conversion on the 5.75% Convertible Notes had impacts on the Company’s earnings per share calculations as follows:
