A par fund, or participating fund, is the pool of assets an insurer keeps for its participating policies. Policyholders share in its profits through bonuses or dividends, which are only fixed once declared.
A participating, or par, policy shares in the results of the insurer's par fund: its investment return, its claims and its expenses. Singapore, Hong Kong and Canada call the design participating; the UK calls it with-profits. Indexed universal life (IUL) is non-participating.
Premiums from par policies are pooled in a fund kept apart from the insurer's other business and invested in government and corporate bonds, equities, property and cash, in a mix the insurer sets. Each policy has contractual benefits, such as the sum assured, and bonuses or dividends paid from the fund's surplus, which are not fixed until declared:
Insurers smooth bonuses, holding back surplus in good years to support bonuses in poor ones, so payouts move less than the markets.
Illustrative figures, not a forecast.
International IUL is non-participating; one contract states on its first page that it is "non-participating (not eligible for dividends)". Each 12-month segment is credited with the index's price change, up to the cap rate, typically 9% to 11%, and never below the floor, 0% in most contracts. The cap is set when the segment starts, so the formula is known in advance; a par bonus is set after the year. Money waiting to enter the index earns a declared rate in the fixed account, the nearest IUL counterpart to dividends left to accumulate at interest. The account value is a contractual claim on the insurer's general account.
Par is short for participating. A par policy shares in the profits of the insurer's par fund through bonuses or dividends, which are not fixed until declared.
No. IUL credits interest from an index formula with a cap and a floor, 0% in most contracts, and pays no dividends. The full comparison with participating whole of life is in IUL vs whole of life.
It is a dividend option on a par policy. The declared dividend stays with the insurer, earns interest at a rate the insurer sets, and can be withdrawn later. The other usual options are cash, lower premiums and paid-up additions.
