Regulatory Balancing Accounts
 
The Utility's recovery of revenue requirements and costs is generally decoupled from the volume of sales.  The Utility records (1) differences between the Utility's authorized revenue requirement and actual customer billings, and (2) differences between incurred costs and customer billings.  To the extent these differences are probable of recovery or refund over the next 12 months, the Utility records a current regulatory balancing account receivable or payable.  Regulatory balancing accounts that the Utility does not expect to collect or refund over the next 12 months are included in other noncurrent assets - regulatory assets or noncurrent liabilities - regulatory liabilities, respectively, in the Condensed Consolidated Balance Sheets.
 
The Utility sells and delivers electricity and natural gas.  The Utility also administers public purpose programs, primarily related to customer energy efficiency programs.  The balancing accounts associated with these items will fluctuate during the year based on seasonal electric and gas usage and the timing of when costs are incurred and customer revenues are collected.
