Compensation and Retirement Disclosure [Abstract] |
Pension Plans and Postretirement Other Than Pensions | Pension Plans and Postretirement Benefits Other Than Pensions Pension Plans As part of the pension funding provisions contained in the Surface Transportation Extension Act of 2012 passed by Congress in June 2012, SCE's projected 2012 plan contributions have been reduced to $172 million from $263 million, pending a final interest rate to be issued by the IRS. SCE made contributions of $55 million during the six months ended June 30, 2012 and in July 2012, made a further required $58 million contribution to the pension fund. Contributions to date exceed the $55 million currently being collected through customer rates. In the 2012 GRC, SCE requested recovery of plan contributions of $168 million with recovery of any undercollection through the continuation of the existing balancing account mechanism. This proposal has been challenged by intervenors and is pending the outcome of the 2012 GRC decision. Annual contributions to these plans are expected to be, at a minimum, equal to the related annual expense. Expense components are:
