Schedule of Reserves | Reserves for the Site. As the result of the proposed consent decree, and assuming it is ultimately approved and stands on appeal, our assessment of the range of probable outcomes for this matter has changed. The higher end of our range of our exposure is now lower; however, the lower end of the range is higher. We increased our reserve by $40.0 million as of December 31, 2016, to reflect our analysis of the range of potential outcomes in this matter and our current estimate of the most likely scenario. Our reserve is set forth below:
