SHAREHOLDERS' EQUITY

6 Months Ended

Jun. 30, 2021

Basic and diluted income per share was determined based on the following share data (in thousands):


	Three Months Ended June 30,		Six Months Ended June 30,
	2021	2020	2021	2020
Weighted average basic common shares	13,243	12,984	13,157	12,971
Effect of stock options	394	—	523	592
Effect of dilutive share awards	72	—	103	91
Effect of Convertible Senior Notes and warrants	10	—	130	300
Weighted average diluted common shares	13,719	12,984	13,913	13,954

For the second quarter of 2021, the weighted average shares that were anti-dilutive, and therefore excluded from the calculation of diluted income per share, included options to purchase 0.9 million shares of common stock and 0.2 million restricted stock units. For the first six months of 2021, the weighted average shares that were anti-dilutive included options to purchase 0.4 million shares of common stock.

For the second quarter of 2020, the Company had a loss from continuing operations and, as a result, no potentially dilutive securities were included in the denominator for computing diluted loss per share, because the impact would have been anti-dilutive. Accordingly, the weighted average basic shares outstanding was used to compute loss per share. Approximately 0.8 million shares related to potentially dilutive securities were excluded from the calculation of diluted loss per share for the second quarter of 2020, because their inclusion would have been anti-dilutive. For the second quarter of 2020, the weighted average shares that were anti-dilutive included options to purchase 0.7 million shares of common stock and 0.1 million restricted stock units. For the first six months of 2020, the weighted average shares that were anti-dilutive included options to purchase 0.2 million shares of common stock.

The convertible notes and the warrants issued by the Company could be converted into the Company’s common stock, subject to certain contingencies. See Note 13—Debt for additional information. Shares of the Company's common stock associated with the 0.50% Convertible Senior Notes due July 15, 2025 were excluded from the calculation of diluted income per share for the second quarter and first six months of 2021 as they were anti-dilutive since the conversion price of the notes was greater than the average market price of the Company’s common stock during the relevant periods. Shares of the Company's common stock associated with the warrants were excluded from the calculation of diluted income per share for the

second quarter and first six months of 2021 and the first six months of 2020 as they were anti-dilutive since the strike price of the warrants was greater than the average market price of the Company's common stock during the relevant periods.

Common Stock Repurchases

In each of February 2018 and February 2019, the board of directors authorized and the Company announced the repurchase of up to $100.0 million and $150.0 million, respectively, of LendingTree's common stock. There were no repurchases of the Company's common stock during the first six months of 2021 and 2020. At June 30, 2021, approximately $179.7 million of the previous authorizations to repurchase common stock remain available.
