Quality incentive premium revenue recognized
The following table quantifies the quality incentive premium revenue recognized for the periods presented, including the amounts earned in the periods presented and prior periods. Although the reasonably possible effects of a change in estimate related to quality incentive premium revenue as of December 31, 2016 are not known, we have no reason to believe that the adjustments to prior periods noted below are not indicative of the potential future changes in our estimates as of December 31, 2016, other than the Texas quality revenue recognized in the second quarter of 2016 described above.
