Retirement Benefits Retirement Benefits
CMS Energy and Consumers provide pension, OPEB, and other retirement benefits to employees under a number of different plans.
In September 2020, CMS Energy and Consumers determined it was probable that 2020 lump-sum payments to retired employees under DB Pension Plan A would exceed the plan’s service cost and interest cost components of net periodic cost for the year. These lump-sum payments constitute pension plan liability settlements; once such settlements meet the service and interest cost threshold, recognition in earnings is required. As a result, in accordance with GAAP, CMS Energy, including Consumers, performed a remeasurement of DB Pension Plan A as of August 31, 2020 and recognized a settlement loss of $36 million; of this amount, $35 million was deferred as a regulatory asset. Consumers recognized a settlement loss of $35 million, all of which was deferred as a regulatory asset. CMS Energy and Consumers will amortize the regulatory asset over nine years.
As a result of the remeasurement, the liability for DB Pension Plan A increased by $252 million at CMS Energy, with an offsetting increase in the associated regulatory asset of $245 million and a $7 million loss to AOCI. At Consumers, the liability and associated regulatory asset increased by $245 million.
