The companies previously announced in June 2015 that POZEN would acquire Tribute and the combined company would be renamed Aralez Pharmaceuticals. With planned business operations in Ireland, Canada and the United States, the Canadian domicile offers a substantially similar corporate and tax structure to the previous Irish domicile, and will benefit from Tribute's…strong presence in Canada where Tribute is incorporated and from where it has always operated.
Hmm—there are clearly some tax-related details that entered into this decision; the company would not postpone the merger and send out all new proxies just for the reason stated above.
