10.	STOCKHOLDERS’ EQUITY

Stock Split and Treasury Stock

On January 27, 2017, our Board of Directors (“Board”) approved a two-for-one stock split of our common stock in the form of a stock dividend paid on March 31, 2017 to shareholders of record as of close of business on February 16, 2017. All share and per share information have been retroactively adjusted to reflect the stock split and the incremental par value of the newly issued shares was recorded with the offset to additional paid-in capital.

On March 31, 2017, we retired 6.2 million shares of treasury stock. The retired stock had a carrying value of $158.9 million, which was deducted from common stock, for the par value of the retired shares, and from retained earnings, for the excess of cost over the par value.
