In the United States, an annuity is a contractually executed, relatively low-risk investment product, where the insured pays a life insurance company a lump-sum premium at the start of the contract. That money is to be paid back to the insured in fixed, incremental amounts, over some future period. The insurer invests the premium; the resulting profit/return on investment funds the payments received by the insured and compensate the insurer. Conventional annuity contracts provide a predictable, guaranteed stream of future income until the death(s) of the beneficiaries(s) named in the contract, or, until a future termination date — whichever occurs first
Although annuities have existed in their present form only for a few decades, the idea of paying out a stream of income to an individual or family dates back to the Roman Empire. The Latin word annua meant annual stipends, and during the reign of the emperors, the word signified a contract that made annual payments. Individuals would make a single large payment into the annua and then receive an annual payment each year until death, or for a specified period of time. The Roman speculator and jurist Gnaeus Domitius Annius Ulpianus is cited as one of the earliest dealers of these annuities, and he is also credited with creating the first actuarial life table. Roman soldiers were paid annuities as a form of compensation for military service. During the Middle Ages, annuities were used by feudal lords and kings to help cover the heavy costs of their constant wars and conflicts with each other. At this time, annuities were offered in the form of a ton-tine, or a large pool of cash from which payments were made to investors.
One of the early recorded uses of annuities in the United States was by the Presbyterian Church in 1720. The purpose was to provide a secure retirement to aging ministers and their families, and was later expanded to assist widows and orphans. In 1912, Pennsylvania Company Insurance was among the first to begin offering annuities to the general public in the United States. Some prominent figures who are noted for their use of annuities include: Benjamin Franklin assisting the cities of Boston and Philadelphia; Babe Ruth avoiding losses during the great depression, O. J. Simpson protecting his income from lawsuits and creditors. Ben Bernanke in 2006 disclosed that his major financial assets are two annuities.
Annuity contracts in the United States are defined by the Internal Revenue Code and regulated by the individual states. Variable annuities have features of both life insurance and investment products. In the U.S., annuity insurance may be issued only by life insurance companies, although private annuity contracts may be arranged between donors to non-profits to reduce taxes. Insurance companies are regulated by the states, so contracts or options that may be available in some states may not be available in others. Their federal tax treatment, however, is governed by the Internal Revenue Code. Variable annuities are regulated by the Securities and Exchange Commission and the sale of variable annuities is overseen by the Financial Industry Regulatory Authority.
There are two possible phases for an annuity, one phase in which the customer deposits and accumulates money into an account (the deferral phase), and another phase in which customers receive payments for some period of time (the annuity or income phase). During this latter phase, the insurance company makes income payments that may be set for a stated period of time, such as five years, or continue until the death of the customer(s) named in the contract. Annuitization over a lifetime can have a death benefit guarantee over a certain period of time, such as ten years. Annuity contracts with a deferral phase always have an annuity phase and are called deferred annuities. An annuity contract may also be structured so that it has only the annuity phase; such a contract is called an immediate annuity. Note this is not always the case.
The term "annuity," as used in financial theory, is most closely related to what is today called an immediate annuity. This is an insurance policy which, in exchange for a sum of money, guarantees that the issuer will make a series of payments. These payments may be either level or increasing periodic payments for a fixed term of years or until the ending of a life or two lives, or even whichever is longer. It is also possible to structure the payments under an immediate annuity so that they vary with the performance of a specified set of investments, usually bond and equity mutual funds. Such a contract is called a variable immediate annuity. See also life annuity, below.
A life annuity works somewhat like a loan that is made by the purchaser (contract owner) to the issuing (insurance) company, which pays back the original capital or principal (which isn't taxed) with interest and/or gains to the annuitant on whose life the annuity is based. The assumed period of the loan is based on the life expectancy of the annuitant. In order to guarantee that the income continues for life, the insurance company relies on a concept called cross-subsidy or the "law of large numbers". Because an annuity population can be expected to have a distribution of lifespans around the population's mean age, those dying earlier will give up income to support those living longer whose money would otherwise run out. Thus it is a form of longevity insurance.
A life annuity, ideally, can reduce the "problem" faced by a person when they don't know how long they will live, and so they don't know the optimal speed at which to spend their savings. Life annuities with payments indexed to the Consumer Price Index might be an acceptable solution to this problem, but there is only a thin market for them in North America.
For an additional expense, an annuity or benefit rider can be purchased on another life such as a spouse, family member or friend for the duration of whose life the annuity is wholly or partly guaranteed. For example, it is common to buy an annuity which will continue to pay out to the spouse of the annuitant after death, for so long as the spouse survives. The annuity paid to the spouse is called a recessionary annuity or survivor-ship annuity. However, if the annuitant is in good health, it may be more advantageous to select the higher payout option on his or her life only and purchase a life insurance policy that would pay income to the survivor.
The pure life annuity can have harsh consequences for the annuitant who dies before recovering his or her investment in the contract. Such a situation, called a forfeiture, can be mitigated by the addition of a period-certain feature under which the annuity issuer is required to make annuity payments for at least a certain number of years; if the annuitant outlives the specified period certain, annuity payments continue until the annuitant's death, and if the annuitant dies before the expiration of the period certain, the annuitant's estate or beneficiary is entitled to the remaining payments certain. The trade off between the pure life annuity and the life-with-period-certain annuity is that the annuity payment for the latter is smaller. A viable alternative to the life-with-period-certain annuity is to purchase a single-premium life policy that would cover the lost premium in the annuity.
Life annuities are priced based on the probability of the annuitant surviving to receive the payments. Longevity insurance is a form of annuity that defers commencement of the payments until very late in life. A common longevity contract would be purchased at or before retirement but would not commence payments until 20 years after retirement. If the nominee dies before payments commence there is no payable benefit. This drastically reduces the cost of the annuity while still providing protection against outliving one's resources.
The second usage for the term annuity came into being during the 1970s. Such a contract is more properly referred to as a deferred annuity and is chiefly a vehicle for accumulating savings with a view to eventually distributing them either in the manner of an immediate annuity or as a lump-sum payment.
