SHAREHOLDERS' EQUITY

9 Months Ended

Sep. 30, 2020

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



	Three Months Ended September 30,		Nine Months Ended September 30,
	2020	2019	2020	2019
Weighted average basic common shares	13,033	12,890	12,992	12,805
Effect of stock options	—	726	—	760
Effect of dilutive share awards	—	136	—	176
Effect of Convertible Senior Notes and warrants	—	880	—	888
Weighted average diluted common shares	13,033	14,632	12,992	14,629

For the three and nine months ended September 30, 2020, the Company had losses 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 1.3 million and 1.1 million shares related to potentially dilutive securities were excluded from the calculation of diluted loss per share for the three and nine months ended September 30, 2020, respectively, because their inclusion would have been anti-dilutive. For the three and nine months ended September 30, 2020, the weighted average shares that were anti-dilutive included options to purchase 0.1 million and 0.2 million shares of common stock, respectively.

For each of the three and nine months ended September 30, 2019, the weighted average shares that were anti-dilutive included options to purchase 0.1 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 14—Debt for additional information. Shares of the Company's common stock associated with the 0.50% Convertible Senior Notes due July 15, 2025 and the warrants issued by the Company in 2020 were excluded from the calculation of diluted loss per share for the three and nine months ended September 30, 2020, as they were anti-dilutive since the conversion price of the notes and the strike price of the warrants were greater than the average market price of the Company's common stock during these 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. During the first nine months of 2019, the Company purchased 18,580 shares of its common stock for aggregate consideration of $4.3 million. At September 30, 2020, approximately $179.7 million of the previous authorizations to repurchase common stock remain available.
