| 1 |  | The mortality assumption for 2015 and 2014 for benefit obligations was based on the RP-2014 mortality table, with projection scales MP-2015 for 2015 and MP-2014 for 2014. The mortality assumption for 2013 was based on the RP-2000 mortality tables with projection of future mortality improvements using Scale AA, which aligned with the IRS prescriptions for cash funding valuations under the Pension Protection Act of 2006. The mortality assumption for net periodic benefit cost for 2015 was based on the RP-2014 mortality table with projection scale MP-2014, and for 2014 and 2013 was based on the RP-2000 mortality table.
| 2 |  | The discount rate reflects the rate at which benefits could be effectively settled and is equal to the equivalent single rate resulting from a yield-curve analysis. This analysis incorporated the projected benefit payments specific to CMS Energy’s and Consumers’ DB Pension Plan and OPEB Plan and the yields on high-quality corporate bonds rated Aa or better.
| 3 |  | In January 2016, CMS Energy and Consumers changed the method in which they determine the discount rate used to calculate the service cost and interest expense components of net periodic benefit costs for the DB Pension and OPEB Plans. Historically, the discount rate used for this purpose represented a single weighted-average rate derived from the yield curve used to determine the benefit obligation. CMS Energy and Consumers have elected to use instead a full-yield-curve approach in the estimation of service cost and interest expense; this approach is more accurate in that it applies individual spot rates along the yield curve to future projected benefit payments based on the time of payment. CMS Energy and Consumers expect that this change will result in a decrease in the service cost and interest expense components of net periodic benefit costs for the DB Pension and OPEB Plans, with an offsetting impact to the actuarial gain or loss recorded in, and later amortized from, the associated regulatory asset and AOCI. This change represents a change in accounting estimate and will not impact years prior to 2016.
| 4 |  | CMS Energy and Consumers determined the long-term rate of return using historical market returns, the present and expected future economic environment, the capital market principles of risk and return, and the expert opinions of individuals and firms with financial market knowledge. CMS Energy and Consumers considered the asset allocation of the portfolio in forecasting the future expected total return of the portfolio. The goal was to determine a long-term rate of return that could be incorporated into the planning of future cash flow requirements in conjunction with the change in the liability. Annually, CMS Energy and Consumers review for reasonableness and appropriateness the forecasted returns for various classes of assets used to construct an expected return model. CMS Energy’s and Consumers’ expected long-term rate of return on DB Pension Plan assets was 7.5 percent in 201 5. The actual return (loss) on DB Pension Plan assets was (2.0) percent in 201 5, 7.4 percent in 2014, and 12.5 percent in 201 3.

| 1 |  | The actuarial loss for 2014 was primarily the result of lowering the discount rates used in calculating the plans’ obligations and using the RP-2014 mortality table during the annual measurement of benefit obligations.
| 2 |  | CMS Energy received less than $1 million in 2015, $4 million in 2014, and $5 million in 2013 for the Medicare Part D subsidies. Consumers received less than $1 million in 2015 and $4 million in each of 2014 and 2013 for the Medicare Part D subsidies. The Medicare Part D subsidy payments are used to pay OPEB Plan benefits.
| 3 |  | At December 31, 2015, $368 million of the total funded status of the DB Pension Plan was attributable to Consumers, based on an allocation of expenses. At December 31, 2014, $532 million of the total funded status of the DB Pension Plan was attributable to Consumers, based on an allocation of expenses.

| 1 |  | The mortality assumption for 2015 and 2014 for benefit obligations was based on the RP-2014 mortality table, with projection scales MP-2015 for 2015 and MP-2014 for 2014. The mortality assumption for 2013 was based on the RP-2000 mortality tables with projection of future mortality improvements using Scale AA, which aligned with the IRS prescriptions for cash funding valuations under the Pension Protection Act of 2006. The mortality assumption for net periodic benefit cost for 2015 was based on the RP-2014 mortality table with projection scale MP-2014, and for 2014 and 2013 was based on the RP-2000 mortality table.
| 2 |  | The discount rate reflects the rate at which benefits could be effectively settled and is equal to the equivalent single rate resulting from a yield-curve analysis. This analysis incorporated the projected benefit payments specific to CMS Energy’s and Consumers’ DB Pension Plan and OPEB Plan and the yields on high-quality corporate bonds rated Aa or better.
| 3 |  | In January 2016, CMS Energy and Consumers changed the method in which they determine the discount rate used to calculate the service cost and interest expense components of net periodic benefit costs for the DB Pension and OPEB Plans. Historically, the discount rate used for this purpose represented a single weighted-average rate derived from the yield curve used to determine the benefit obligation. CMS Energy and Consumers have elected to use instead a full-yield-curve approach in the estimation of service cost and interest expense; this approach is more accurate in that it applies individual spot rates along the yield curve to future projected benefit payments based on the time of payment. CMS Energy and Consumers expect that this change will result in a decrease in the service cost and interest expense components of net periodic benefit costs for the DB Pension and OPEB Plans, with an offsetting impact to the actuarial gain or loss recorded in, and later amortized from, the associated regulatory asset and AOCI. This change represents a change in accounting estimate and will not impact years prior to 2016.
| 4 |  | CMS Energy and Consumers determined the long-term rate of return using historical market returns, the present and expected future economic environment, the capital market principles of risk and return, and the expert opinions of individuals and firms with financial market knowledge. CMS Energy and Consumers considered the asset allocation of the portfolio in forecasting the future expected total return of the portfolio. The goal was to determine a long-term rate of return that could be incorporated into the planning of future cash flow requirements in conjunction with the change in the liability. Annually, CMS Energy and Consumers review for reasonableness and appropriateness the forecasted returns for various classes of assets used to construct an expected return model. CMS Energy’s and Consumers’ expected long-term rate of return on DB Pension Plan assets was 7.5 percent in 201 5. The actual return (loss) on DB Pension Plan assets was (2.0) percent in 201 5, 7.4 percent in 2014, and 12.5 percent in 201 3.

| 1 |  | The actuarial loss for 2014 was primarily the result of lowering the discount rates used in calculating the plans’ obligations and using the RP-2014 mortality table during the annual measurement of benefit obligations.
| 2 |  | CMS Energy received less than $1 million in 2015, $4 million in 2014, and $5 million in 2013 for the Medicare Part D subsidies. Consumers received less than $1 million in 2015 and $4 million in each of 2014 and 2013 for the Medicare Part D subsidies. The Medicare Part D subsidy payments are used to pay OPEB Plan benefits.
| 3 |  | At December 31, 2015, $368 million of the total funded status of the DB Pension Plan was attributable to Consumers, based on an allocation of expenses. At December 31, 2014, $532 million of the total funded status of the DB Pension Plan was attributable to Consumers, based on an allocation of expenses.
