[1] On March 31, 2015 the Company granted to its Chief Executive Officer ("CEO") options to purchase 400,000 of the Company's ordinary shares. On the same date, the Company cancelled 112,500 of the CEO's out-of-money options. The Company accounted for the cancellation of options, accompanied by the concurrent grant of options in accordance with ASC 718-20-35-8, "Cancellation and Replacement," and calculated the incremental compensation cost as the excess of the fair value of the replacement award over the fair value of the cancelled award at the cancellation date.
