SAG holds annual teleconference meetings to review recommended NTG values prepared by independent evaluators and reach agreement on NTG values for the next Program Year. See below for background information and final Net-to-Gross materials. NTG discussions for the program year beginning on June 1, 2017 were held in February 2017 to reach agreement on NTG values by March 1, 2017. Draft NTG recommendations are removed from this page after NTG values are finalized.
