Most insurance companies have reported earnings, and the news is generally good for life insurers. With few exceptions, life insurance companies have met or beaten analyst expectations, according to UBS Investment Research.

Earnings from The Hartford Group , Prudential Financial , and Nationwide Financial should be in within the week.
