The LV= with-profits fund generated a return on investment of 15.4% in 2009.
An estimated £76.3m in bonuses will be added to the company's with-profits policies.
Annual bonus rates on currently-sold with-profits show increases for the 2008 entry pensions annuity of 1.7% compared with last year, the 2009/10 entry pension annuity of 2.5% and the income bond of 0.25% on 2008.
However bonus rates were cut on the 2007 entry pensions annuity, and held on
Life ISA, flexible savings plan, personal pensions, growth bond and the tax-free savings plan.
The company says with further equity market volatility likely in the future, it has taken the opportunity in the last two months to crystallise previous equity gains and increase the weighting of fixed-interest investments in the fund.
As of 28 February, the fund was 47.6% exposed to equities, compared to 53.8% on 31 December 2009.
The manager has increased the fund's exposure to fixed interest from 22.2% as of 31 December last year, to 31.9% on 28 February.
The fund is currently 100% invested.
John Perks, LV= customer solutions director, says the company was able to do well despite volatility in equity markets in recent years because of the financial strength it gains as a mutual, with no corporate borrowings and no shareholders to pay.
