1 | Under GAAP, a settlement is recorded when lump-sum payments exceed estimated annual service and interest costs. Lump sum payments made in April 2017 to Edison International executives retiring in 2016 from the Executive Retirement Plan exceeded the estimated service and interest costs, resulting in a partial settlement of that plan. A settlement loss of approximately $7.7 million ($4.6 million after tax) was recorded at Edison International in the second quarter of 2017.
2 | Includes the amount of net loss reclassified from other comprehensive loss. The amount reclassified for Edison International and SCE was $2 million and $1 million, respectively, for the three months ended June 30, 2017, and $5 million and $3 million, respectively, for the six months ended June 30, 2017. The amount reclassified for Edison International and SCE was $3 million and $1 million, respectively, for the three months ended June 30, 2016, and $6 million and $3 million, respectively, for the six months ended June 30, 2016.
