Subsequent event | 16 Subsequent event On October 27, 2017, the Company completed its public offering which was announced on October 23, 2017. The Company issued and sold 5,000,000 ordinary shares at $18.25 per ordinary share, resulting in gross proceeds to the Company of approximately $91.3 million. The net proceeds to the Company from this offering were approximately $85.4 million, after deducting underwriting discounts and commissions and other estimated offering expenses payable by the Company. The Company has granted the underwriters an option to purchase up to 750,000 ordinary shares at the public offering price of $18.25 for within thirty days of the date of the underwriting agreement. The Company intends to use the net proceeds from this offering to fund the continued clinical development of AMT-061 in hemophilia B and other programs, including AMT-130 in Huntington’s disease and other preclinical product candidates focused on rare and orphan diseases and to fund general corporate and working capital purposes. The above equity financing entitles the Company to extend the interest interest-only payment period of its 2016 Amended Facility by 12 months from November 2017 to November 2018 as described in footnote 8.
