Basic earnings (loss) per share includes no dilution and is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per share reflect, 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 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.

As of December 31, 2019, of the total potentially dilutive shares related to restricted stock-based awards and stock options, less than 0.1 million were anti-dilutive, compared to approximately 0.2 million that were anti-dilutive as of December 31, 2018. Additionally, as of December 31, 2019, of total potentially dilutive shares related to potential conversion of the Company’s 5.75% Convertible Notes, all of the shares (or approximately 33.7 million) were anti-dilutive, compared to approximately 8.1 million as of December 31, 2018.

As of December 31, 2019, of the performance related restricted stock-based awards issued in connection with the Company’s named executive officers, approximately 0.3 million shares were anti-dilutive compared to none that were anti-dilutive as of December 31, 2018.

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

	FY 2019		FY 2018
Basic		10,559		6,734
Effect of assumed vesting of restricted stock		—		—
Effect of convertible notes subject to conversion		—		—
Diluted		10,559		6,734

As a result of the Company being in a net loss position during FY 2019 and FY 2018, dilution from the exercise of vesting of restricted stock has been excluded in the diluted earnings per share calculation.

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 FY 2019 and FY 2018, adjustments to the Company’s redeemable non-controlling interest and effects of the potential conversion of the 5.75% Convertible Notes had impacts on the Company’s earnings per share calculations as follows:

	Year Ended			Year Ended
	December 31, 2019			December 31, 2018
For earnings (loss) per share - basic:
Net loss attributable to Iconix Brand Group, Inc.	$	(111,513	)	$	(100,521	)
Accretion of redeemable non-controlling interest		—			—
Net income (loss) attributable to Iconix Brand Group, Inc. after accretion of redeemable non- controlling interest for basic earnings (loss) per share	$	(111,513	)	$	(100,521	)

For earnings (loss) per share - diluted:
Net loss attributable to Iconix Brand Group, Inc.	$	(111,513	)	$	(100,521	)
Effect of potential conversion of 5.75% Convertible Notes ⁽¹⁾		—			—
Accretion of redeemable non-controlling interest		—			—
Net loss attributable to Iconix Brand Group, Inc. after the effect of potential conversion of 5.75% Convertible Notes for diluted earnings (loss) per share	$	(111,513	)	$	(100,521	)

Earnings (loss) per share:
Basic	$	(10.56	)	$	(14.93	)
Diluted	$	(10.56	)	$	(14.93	)
Weighted average number of common shares outstanding:
Basic		10,559			6,734
Diluted		10,559			6,734

⁽¹⁾	There was no effect of potential conversion of the Company’s 5.75% Notes on the Company’s diluted earnings per share calculation for FY 2019 or FY 2018, as the effect was anti-dilutive.
