SCEcorp, parent of Southern California Edison Co., reported a 5% decline in first-quarter earnings and announced a 2-for-1 stock split.

Net income for the quarter slipped to $148.9 million, or 67 cents a share, from $156.7 million, or 71 cents, in the year-earlier period. Revenue increased to $1.78 billion from $1.72 billion.
