Prudential, the largest U.S. life insurer by assets, earned $1.3 billion (980.69 million pounds), or $3.01 per share, in adjusted profit during the third quarter, up from $1.2 billion, or $2.66 per share, in the year-ago period.

Its profit topped analysts' average estimate of $2.71 per share, according to Thomson Reuters I/B/E/S.

Although Prudential's annuities sales declined dramatically, the insurer still generated more fees from the business because market performance drove overall account values to a record high. It reported record assets under management and retirement account values for the same reason.

During the third quarter, major global stock indexes posted gains, with some benchmarks like the S&P 500 <.SPX> hitting new records. Bond markets were impacted by an uptick in interest rates, which the insurance industry has long been waiting for to drive profits higher.

Adjusted operating earnings in Prudential's U.S. retirement solutions and investment management business, its largest division, rose about 6 percent to $1.1 billion.

Its U.S. individual life and group insurance division reported $211 million in adjusted operating earnings, a 22 percent jump.

The adjusted earnings exclude one-time items related to the deferred cost of acquiring new policies, reserves for minimum annuity benefits and legal costs in either quarter.
