Koo, 

No one from Resverlogix has ever given a guarantee of end of BETonMACE by end of 2018. If you or someone else has an official company communication that provides a 2018 guarantee, then share the quote and source here and we can discuss it. But keep in mind that hopes, plans, expectations and other forward looking statements covered by safe harbor are not the same as a guarantee.
