ExxonMobil 4Q earnings dive on low oil prices

ExxonMobil reported a big drop in fourth-quarter earnings Tuesday, as low oil and natural prices continued to weigh on results. Net income in the fourth-quarter plunged 39.6 percent to $1.7 billion, while full year earnings fell by more than half to $7.8 billion. Results also were marred by a $2 billion asset downgrade due to low prices, much of it due to impairments in a natural gas region in the Rocky Mountains in the middle of the United States.
The asset write down resulted in a loss of $642 million in ExxonMobil's normally lucrative upstream business, which explores for and produces petroleum.
