The increase in the costs of our subscription right plans is primarily related to the issuance of our subscription right plans 2020 to a higher number of beneficiaries as well as a higher fair value of the attached subscription rights mainly due to the increase in the price and the volatility of the Galapagos share. Under these subscription right plans, 2,173,335 subscription rights were granted to the beneficiaries of the plans. The subscription rights have an exercise term of eight years as of the date of the offer and have an exercise price of €168.42 (the average closing price of the share on Euronext Amsterdam and Brussels during the thirty days preceding the date of the offer on April 17, 2020). The subscription rights are not transferable and can in principle not be exercised prior to January 1, 2024. Each subscription right gives the right to subscribe to one new Galapagos share.
