Net income per share attributable to Tyson:
Class A basic	$	1.24	$	1.29	$	3.84	$	3.61
Class B basic	$	1.12	$	1.17	$	3.47	$	3.28

Approximately 1 million of our stock-based compensation shares were antidilutive for each of the three and nine months ended July 1, 2017. We had no stock-based compensation shares that were antidilutive for the three and nine months ended July 2, 2016.

We have two classes of capital stock, Class A stock and Class B stock. Cash dividends cannot be paid to holders of Class B stock unless they are simultaneously paid to holders of Class A stock. The per share amount of cash dividends paid to holders of Class B stock cannot exceed 90% of the cash dividends paid to holders of Class A stock.

We allocate undistributed earnings based upon a 1 to 0.9 ratio per share to Class A stock and Class B stock, respectively. We allocate undistributed earnings based on this ratio due to historical dividend patterns, voting control of Class B shareholders and contractual limitations of dividends to Class B stock.
