8. Fair value re-measurement of share subscription agreement

On 16 December 2015, Gilead Sciences, Inc. and Galapagos NV entered into a global collaboration for the development and commercialization of filgotinib, in the framework of which Gilead committed to an upfront payment of $725 million consisting of a license fee of $300 million and a $425 million equity investment in Galapagos NV by subscribing to new shares at a price of €58 per share, including issuance premium. This agreement was effectively completed and entered into force on 19 January 2016 and the full payment was received.

In connection with the agreement, we recognized a deferred income and an offsetting short term financial asset (derivative) of €39 million upon signing of the share subscription agreement with Gilead as required under IAS 39. This financial asset initially reflects the share premium that Gilead committed to pay above our closing share price on the day of entering into the subscription agreement. Under IAS 39 the fair value of the financial asset is re-measured at year-end and again upon entering into force of the share subscription agreement on 19 January 2016, when the financial asset expired. Variations in fair value of the financial asset are recorded in the income statement.

The decrease in the fair value of the financial asset resulting from the increase in the Galapagos share price between signing of the subscription agreement and 31 December 2015 resulted in a negative, non-cash fair value charge of €30.6 million in the financial results. The subsequent increase in the fair value of the financial asset resulting from the decrease in our share price between 1 January 2016 and 19 January 2016 will result in a positive non-cash gain of €57.5 million in the financial result of the first quarter of 2016.
