In DESC’s Consolidated Statements of Comprehensive Income, the service cost component of net periodic benefit (credit) cost is reflected in other operations and maintenance expense with the non-service cost components reflected in other income. Components of net periodic benefit cost (credit) recorded by DESC were as follows:

During the three months ended March 31, 2023, DESC made no contributions to its pension trust and does not expect to make any such contributions in 2023. DESC recovers current pension costs through either a rate rider that may be adjusted annually for retail electric operations or through cost of service rates for gas operations.
