1. 250-980Regulated Operations250 Accounting Changes and Error Corrections

   This Subtopic applies the general accounting change and error correction rules of Topic 250 to entities with regulated operations that meet the criteria of paragraph 980-10-15-2 (so that costs designated for future recovery by the regulator are probable of recovery). Its core rule is that a change in accounting method that does not affect costs allowable for rate-making purposes is reported the same way an unregulated entity would report it, whereas a change that does affect allowable costs is generally implemented the way it is implemented for regulatory purposes. It also confirms that prior period adjustments are limited to error corrections and prior interim period adjustments of the current fiscal year, and that previously unaccrued estimated refunds are charged to income when the accrual criteria are first met.
