Related Party Transactions [Abstract] |
Related Party Transactions | Related Party Transactions Edison International and SCE provide and receive various services to and from its affiliates. Services provided to Edison International by SCE are priced at fully loaded cost (i.e., direct cost of good or service and allocation of overhead cost). Specified administrative services such as payroll, employee benefit programs, all performed by Edison International or SCE employees, are shared among all affiliates of Edison International. Costs are allocated based on one of the following formulas: percentage of time worked, equity in investment and advances, number of employees, or multi-factor (operating revenues, operating expenses, total assets and number of employees). Edison International allocates various corporate administrative and general costs to SCE and other subsidiaries using established allocation factors. Management believes that the methods used to allocate expenses are reasonable and meet the reporting and accounting requirements of its regulatory agencies. The tables below summarize Edison International's and SCE's related party receivables and payables with unconsolidated affiliates, net of allowances for uncollectible accounts. EME amounts outstanding prior to December 17, 2012 were excluded from Edison International's table as these transactions were included and eliminated from Edison International's consolidated financial statements.
