\b\ We constrain RXC 03 to be equal to average plan liability for RXC 03 drugs, RXC 04 to be equal to the
  average plan liability for RXC 04 drugs, and we constrain RXC 03 x HCC142 and RXC 04 x HCC184, 183, 187, 188
  to be equal to zero. See March 2016 Risk Adjustment Methodology Discussion Paper (2016 March, 16), available
