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,
	2019	2018	2019	2018
Weighted average basic common shares	12,805	12,416	12,762	12,254

For each of the three and six months ended June 30, 2019, the weighted average shares that were anti-dilutive, and therefore excluded from the calculation of diluted income per share, included options to purchase 0.1 million shares of common stock. For each of the three and six months ended June 30, 2018, the weighted average shares that were anti-dilutive, and therefore excluded from the calculation of diluted income per share, included options to purchase 0.4 million shares of common stock.

The 0.625% Convertible Senior Notes due June 1, 2022 and the warrants issued by the Company in 2017 could be converted into the Company’s common stock in the future, subject to certain contingencies. See Note 13—Debt for additional information.
