The following table sets forth the computation of basic and diluted net income per common share (in thousands, except per share amounts):



	Year ended March 31,
	2016		2015		2014
Net income attributable to Microchip Technology	$	324,132	$	369,009	$	395,281
Weighted average common shares outstanding	203,384		200,937		198,291
Dilutive effect of stock options and RSUs	3,350		3,642		3,910
Dilutive effect of 2037 junior subordinated convertible debentures	10,654		18,982		15,429
Weighted average common and potential common shares outstanding	217,388		223,561		217,630
Basic net income per common share attributable to Microchip Technology stockholders	$	1.59	$	1.84	$	1.99
Diluted net income per common share attributable to Microchip Technology stockholders	$	1.49	$	1.65	$	1.82

The Company computed basic earnings per common share attributable to its stockholders using net income available to common stockholders and the weighted average number of common shares outstanding during the period. The Company computed diluted earnings per common share attributable to its stockholders using net income available to stockholders and the weighted average number of common shares outstanding plus potentially dilutive common shares outstanding during the period.

Potentially dilutive common shares from employee equity incentive plans are determined by applying the treasury stock method to the assumed exercise of outstanding stock options and the assumed vesting of outstanding RSUs.

Diluted net income per common share attributable to stockholders for fiscal 2016, 2015, and 2014 includes 10,654,070, 18,982,440 and 15,429,003 shares, respectively, issuable upon the exchange of the Company's 2.125% junior subordinated convertible debentures due December 15, 2037 (see Note 15). The debentures have no impact on diluted net income per common share unless the average price of the Company's common stock exceeds the conversion price because the principal amount of the debentures will be settled in cash upon conversion. Prior to conversion, the Company will include, in the diluted net income per common share calculation, the effect of the additional shares that may be issued when the Company's common stock price exceeds the conversion price using the treasury stock method. The weighted average conversion price per share used in calculating the dilutive effect of the convertible debt for fiscal 2016, 2015 and 2014 was $24.73, $25.48 and $26.32, respectively.

There were no shares issuable upon the exchange of the Company's 1.625% senior subordinated convertible debentures due February 15, 2025 (see Note 14). The debentures have no impact on diluted net income per common share unless the average price of the Company's common stock exceeds the conversion price because the principal amount of the debentures will be settled in cash upon conversion. Prior to conversion, the Company will include, in the diluted net income per common share calculation, the effect of the additional shares that may be issued when the Company's common stock price exceeds the conversion price using the treasury stock method. The weighted average conversion price per share used in calculating the dilutive effect of the convertible debt for fiscal 2016 and 2015 was $67.19 and $68.25, respectively.

Weighted average common shares exclude the effect of option shares which are not dilutive. For fiscal 2016 and 2015, the number of option shares that were antidilutive was 298,015 and 19,305, respectively. There were no antidilutive option shares for fiscal 2014.
