Big increases in profits for individual annuity, individual life, group benefits and international life operations helped lead to higher earnings at Hartford Financial Services Group Inc. during the third quarter.

Hartford Financial, Hartford, is reporting $851 million in net income for the latest quarter on $5.8 billion in revenue, compared with $758 million in net income on $7.4 billion in revenue for the third quarter of 2006.

Net income from life operations increased 23%, to $525 million, the company says.

Sales of variable annuities and mutual funds were up 25%, and retail assets under management increased 19%, to $184 billion.

Total company revenue was down because net investment results from equity securities held for trading fell to a loss of $698 million, from a gain of $1.2 billion reported for the third quarter of 2006

The loss on equity securities held for trading “includes investment income and mark-to-market effects of equity securities held for trading supporting the international variable annuity business, which are classified in net investment income with corresponding amounts credited to policyholders within benefits, losses and loss adjustment expenses,” Hartford says.
