On 15th October, 2010, the board of directors of Ensor Materials Corporation approved a stock option plan for key executives. On 1st January, 2011, 20 million stock options were granted, exercisable for 20 million shares of Ensor's $1 par common stock. The options are exercisable between 1st January, 2014, and 31st December, 2016, at 80% of the quoted market price on 1st January, 2011, which was $15. The fair value of the 20 million options, estimated by an appropriate option pricing model, is $6 per option.
Two million options were forfeited when an executive resigned in 2012. All other options were exercised on 12th July, 2015, when the stock's price jumped unexpectedly to $19 per share.
