Effect of currency on ATryn royalties:

>Is GTC paid by Leo in Euros? More profit compared to 2006 approval!<

Leo converts its ATryn sales in each country from local currency to dollars using the average exchange rate for a given quarter, and this is done before calculating the royalty payable to GTC. Thus, a declining dollar relative to the British pound and the Euro increase GTC’s dollar-denominated royalties.

Effect of currency on ATryn selling price:

ThomasS astutely noted that the dollar has declined substantially relative to the British pound and the Euro in recent years. Although ATryn’s listed selling price in the UK of $22,600 (£11,000) is about 50% higher than the $15K price I had expected, a substantial portion of this difference is attributable to decline of the dollar during the past few years.
