As of September 30, 2022, and December 31, 2021, SJW Group’s regulatory assets, net, not earning a return primarily included postretirement pensions and the unfunded amount of other medical benefits, and business combination debt premiums, net. The total amount of regulatory assets, net not earning a return at September 30, 2022, and December 31, 2021, either by interest on the regulatory asset/liability or as a component of rate base at the allowed rate of return was $86,113 and $84,887, respectively. Balancing and Memorandum Accounts SJWC has established balancing accounts for the purpose of tracking the under-collection or over-collection associated with expense changes and revenue authorized by the CPUC to offset those expense changes. SJWC also maintains memorandum accounts to track revenue impacts due to catastrophic events, certain unforeseen water quality expenses related to new federal and state water quality standards, energy efficiency, water conservation, water tariffs, and other approved activities or as directed by the CPUC. The Monterey Water Revenue Adjustment Mechanism (“MWRAM”) tracks the difference between the revenue received for actual metered sales through the tiered volumetric rate and the revenue that would have been received with the same actual metered sales if a uniform rate would have been in effect. The Water Conservation Memorandum Account (“WCMA”) allows SJWC to track lost revenue, net of related water costs, associated with reduced sales due to water conservation and associated calls for water use reductions. SJWC records the lost revenue captured in the WCMA balancing accounts. Drought surcharges collected are used to offset the revenue losses tracked in the WCMA. On October 11, 2022, the CPUC issued General Rate Case Decision No. 22-10-005, which approved a recovery of $18,174 in balancing and memorandum accounts from customers. Balancing and memorandum accounts recorded to regulatory assets, net for the three and nine months ended September 30, 2022, and 2021 are as follows:
