Basic and diluted earnings per share for the quarter and year ended December 31, 2013 were reduced by $0.05 for the impact of an equity put option related to one of our redeemable non-controlling interests in one of our consolidated subsidiaries. The equity put option allows the non-controlling interest party to sell its ownership interest in a joint venture to the Company at a future date for a minimum pre-established amount. While net income on the consolidated statement of comprehensive income was not reduced by the amount of this equity put option, earnings per share are required to be calculated after reducing net income by the amount of the equity put option.
