Earnings Per Share

EARNINGS PER SHARE

NOTE 6.    EARNINGS PER SHARE

Basic earnings per share ("EPS") is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding during the period. The computation of our diluted EPS is similar to the computation of our basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding (using the if-converted and treasury stock methods), if our outstanding stock options and restricted stock units had been converted to common shares, and if such assumed conversion is dilutive.

The following is a reconciliation of the weighted-average shares outstanding used in the calculation of basic and diluted EPS for the three and nine months ended September 30, 2019 and 2018:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2019		2018		2019		2018
Income from continuing operations	$	7,256	$	35,157	$	46,016	$	127,927
Income from continuing operations attributable to noncontrolling interest		10		7		29		82
Income from continuing operations attributable to Advanced Energy Industries, Inc.	$	7,246	$	35,150	$	45,987	$	127,845
Basic weighted-average common shares outstanding		38,313		38,970		38,258		39,309
Assumed exercise of dilutive stock options and restricted stock units		176		225		199		285
Diluted weighted-average common shares outstanding		38,489		39,195		38,457		39,594
Continuing operations:
Basic earnings per share	$	0.19	$	0.90	$	1.20	$	3.25
Diluted earnings per share	$	0.19	$	0.90	$	1.20	$	3.23

The following restricted stock units were excluded in the computation of diluted earnings per share because they were anti-dilutive:

	Three Months Ended September 30,		Nine Months Ended September 30,

Stock Buyback

In September 2015, our Board of Directors authorized a program to repurchase up to $150.0 million of our stock over a thirty-month period. In November 2017, our Board of Directors approved an extension of the share repurchase program to December 2019 from its original maturity of March 2018. In May 2018 our Board of Directors approved a $50 million increase in its authorization to repurchase shares of Company common stock under this same program. As of September 30, 2019, we had $24.9 million remaining for the future repurchase of shares of our common stock.

In order to execute the repurchase of shares of our common stock, the company periodically enters into stock repurchase agreements. During the three and nine months ended September 30, 2019 and 2018, the company has repurchased the following shares of common stock:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2019		2018		2019		2018
Amount paid to repurchase shares	$	—	$	30,962	$	—	$	69,021
Number of shares repurchased		—		533		—		1,121
Average repurchase price per share	$	—	$	58.12	$	—	$	61.57

There were no shares repurchased from related parties. All shares repurchased were recognized as a reduction to Additional paid-in capital. Repurchased shares were retired and assumed the status of authorized and unissued shares.
