Annuities in the European Union

An annuity certain pays the annuitant for a number of years designated. This option is not suitable for retirement income, as the person may outlive the number of years the annuity will pay.

A life annuity or lifetime immediate annuity is most often used to provide an income in old age (i.e., a pension). This type of annuity may be purchased from an insurance (Ireland and the UK, Life Assurance) company.

This annuity can be compared to a loan which is made by the purchaser to the issuing company, who then pay back the original capital with interest 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 but life annuities are payable until the death of the last surviving annuitant. In order to guarantee that the income continues for life, the investment relies on cross-subsidy. Because an annuity population can be expected to have a distribution of lifespans around the population's mean (average) age, those dying earlier will support those living longer (longevity insurance).

Cross-subsidy remains one of the most effective ways of spreading a given amount of capital and investment return over a lifetime without the risk of funds running out.

Although this will reduce the available payments, an annuity can be arranged to continue until the death of the last survivor of two or more people. For example, many annuities continue to pay out (perhaps at a reduced rate) to the spouse of the main annuitant after his or her death, for as long as the spouse survives. The annuity paid to the spouse is called a reversionary annuity or survivorship annuity. However, if the annuitant is in good health, it may be more beneficial to select the higher payout option on their life only and purchase a life insurance policy that would pay income to the survivor.

Other features such as a minimum guaranteed payment period irrespective of death, known as life with period certain, or escalation where the payment rises by inflation or a fixed rate annually can also be purchased.

Annuities with guaranteed periods are available from most providers. In such a product, if death takes place within the guaranteed period, payments continue to be made to a nominated beneficiary.

Impaired life annuities for smokers or those with a particular illness are also available from some insurance companies. Since the life expectancy is reduced, the annuity rate is better (i.e. a higher annuity for the same initial payment). This can have the unfortunate appearance of one "betting against" the nominee.

Life annuities are priced based on the probability of the nominee 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.

Because immediate annuities generally provide a series of guaranteed payments, the annuity company normally matches its liabilities with government bonds and other high grade bonds, and the market yield available on these bonds largely determines the retail pricing of the annuities. (The companies are usually required by law to invest their funds in this way, to reduce the risk of default.)

These investments are generally regarded as less risky than other investments, such as those linked to the stock market, and probably offer a lower expected return. However fixed annuities do not protect the purchaser against the effects of inflation, which is a material risk.

For many elderly people, the financial risk of living longer than expected and running out of money is a bigger risk than investment risks such as exposure to a falling stock market. Immediate annuities protect against this risk.

Deferred pensions are often used as a savings vehicle by higher rate taxpayers, as in some jurisdictions they get higher rate tax relief on their pension contributions and their fund accumulates without investment returns being subject to tax. The proceeds will be taxed when they are taken as benefits, but maybe at a lower rate. Those in lower tax brackets may be told to avoid deferred pensions because they may not be able to recoup the charges made by the annuity company. (In some jurisdictions, some or all of the proceeds must by law be applied to purchase a pension.)

In technical language an annuity is said to be payable for an assigned status, this being a general word chosen in preference to such words as "time", "term" or "period", because it may include more readily either a term of years certain, or a life or combination of lives. The magnitude of the annuity is the sum to be paid (and received) in the course of each year. Thus, if £100 is to be received each year by a person, he is said to have "an annuity of £100". If the payments are made half-yearly, it is sometimes said that he has "a half-yearly annuity of £100"; but to avoid ambiguity, it is more commonly said he has "an annuity of £100, payable by half-yearly instalments". An annuity is considered as accruing during each instant of the status for which it is enjoyed, although it is only payable at fixed intervals. If the enjoyment of an annuity is postponed until after the lapse of a certain number of years, the annuity is said to be deferred. If an annuity, instead of being payable at the end of each year, half-year, etc., is payable in advance, it is called an annuity-due. The holder of an annuity is called an annuitant, and the person on whose life the annuity depends is called the nominee.[1]

Upon immediate annuitization, a wide variety of options are available in the way the stream of payments is paid. If the annuity is paid over a fixed period independent of any contingency, it is known as an annuity with period certain, or just annuity certain; if it is to continue for ever, it is called a perpetuity; and if in the latter case it is not to commence until after a term of years, it is called a deferred perpetuity. An annuity depending on the continuance of an assigned life or lives would commonly be called a life annuity, but also known as a life-contingent annuity or simply lifetime annuity; but more commonly the simple term "annuity" is understood to mean a life annuity, unless the contrary is stated.[1] The payments can also be paid over the lifetime of the nominee(s) or for a fixed period, whichever is longer. This is known as life with period certain.

A hybrid of these is when the payments stop at death, but also after a predetermined number of payments, if this is earlier: known as a temporary life annuity. The difference with the period certain annuity is that the period certain annuity will keep paying after the death of the nominee until the period is completed.

If not otherwise stated, it is always understood that an annuity is payable yearly, and that the annual payment (or rent, as it is sometimes called) is a single currency unit.[1]

Instances of perpetuities are the dividends upon the public stocks in England, France and some other countries. Thus, although it is usual to speak of £100 consols, the reality is the yearly dividend which the government pays by quarterly instalments. The practice of the French in this is arguably more logical. In speaking of their public funds (rentes) they do not mention the ideal capital sum, but speak of the annuity or annual payment that is received by the public creditor. Other instances of perpetuities are the incomes derived from the debenture stocks of railway companies, also the feu-duties commonly payable on house property in Scotland. The number of years' purchase which the perpetual annuities granted by a government or a railway company realize in the open market, forms a very simple test of the credit of the various governments or railways.[1]

In the United Kingdom, the income from compulsory purchase annuities purchased with pension funds or by an employer immediately on retirement (a Hancock annuity) is treated as taxable income. The income from purchased life annuities, bought by any other means, has an element which is considered return of capital, and only the excess over this is considered a gain that is subject to income tax. The element considered capital return is based on life expectancy and will therefore increase with age.

In the United Kingdom contributions into pension savings are generally net of income tax (i.e. tax relief is available), up to certain limits. On retirement if an annuity is not purchased, retirement income up until the age of 75 can be drawn from the pension fund by using pension income withdrawal commonly known as income drawdown. This is an unsecured pension as opposed to an annuity which is a secured backed pension. Unsecured pensions operate under age-related income limits calculated by the Government Actuarial Department to prevent the fund being eroded too fast. Before A-day, individuals could vary withdrawals between 35% and 100% of a maximum limit, recalculated every three years at what was known as the triennial review. Following changes introduced by HMRC as part of the A-day legislation, individuals can now draw an income between zero and 120% of the "GAD rate". On reaching 75, the individual must then secure their pension fund by the purchase of an annuity, except that up to 25% of the fund can be taken as tax-free cash, also known as the pension commencement lump sum, or enter into an alternatively secured pension (ASP). Under an ASP arrangement the rate of income must fall between 55% and 90% of the GAD rate for a 75-year-old. The GAD rates are subject to periodic review and are based on the return of a level, single life annuity paid monthly in arrears without any guarantee or value protection for an individual in good health. These rates are in turn largely dependent on long-term gilt yields and mortality data.

Unsecured or alternatively secured pensions carry both the investment risk of the invested pension fund and mortality drag that occurs from the loss of cross-subsidy and advancing average age expectancy that occurs in the time over which annuity purchase is delayed.

It appears that it had long been the practice in Holland for life annuities to be granted to nominees of any age, in the constant proportion of double the rate of interest allowed on stock; that is to say, if the towns were borrowing money at 6%, they would be willing to grant a life annuity at 12%, and so on. De Witt states that "annuities have been sold, even in the present century, first at six years' purchase, then at seven and eight; and that the majority of all life annuities now current at the country's expense were obtained at nine years' purchase"; but that the price had been increased in the course of a few years from eleven years' purchase to twelve, and from twelve to fourteen. He also states that the rate of interest had been successively reduced from 6-¼% to 5%, and then to 4%. The principal object of his report is to prove that, taking interest at 4%, a life annuity was worth at least sixteen years' purchase; and, in fact, that an annuitant purchasing an annuity for the life of a young and healthy nominee at sixteen years' purchase, made an excellent bargain.[4]

He argues that it is more to the advantage, both of the country and of the private investor, that the public loans should be raised by way of grant of life annuities rather than perpetual annuities. It appears from De Witt's correspondence with Hudde, that the rate of mortality assumed was deduced from the mortality that had actually prevailed among the nominees on whose lives annuities had been granted in former years. De Witt appears to have come to the conclusion that the probability of death is the same in any half-year from the age of 3 to 53 inclusive; that in the next ten years, from 53 to 63, the probability is greater in the ratio of 3 to 2; that in the next ten years, from 63 to 73, it is greater in the ratio of 2 to 1; and in the next seven years, from 73 to 80, it is greater in the ratio of 3 to 1; and he places the limit of human life at 80. If a mortality table of the usual form is deduced from these suppositions, out of 212 persons alive at the age of 3, 2 will die every year up to 53, 3 in each of the ten years from 53 to 63, 4 in each of the next ten years from 63 to 73, and 6 in each of the next seven years from 73 to 80, when all will be dead.[5]

De Witt calculates the value of an annuity in the following way. Assume that annuities on 10,000 lives each ten years of age, which satisfy the Hm mortality table, have been purchased. Of these nominees 79 will die before attaining the age of 11, and no annuity payment will be made in respect of them; none will die between the ages of 11 and 12, so that annuities will be paid for one year on 9921 lives; 40 attain the age of 12 and die before 13, so that two payments will be made with respect to these lives. Reasoning in this way we see that the annuities on 35 of the nominees will be payable for three years; on 40 for four years, and so on. Proceeding thus to the end of the table, 15 nominees attain the age of 95, 5 of whom die before the age of 96, so that 85 payments will be paid in respect of these 5 lives. Of the survivors all die before attaining the age of 97, so that the annuities on these lives will be payable for 86 years. Having previously calculated a table of the values of annuities certain for every number of years up to 86, the value of all the annuities on the 10,000 nominees will be found by taking 40 times the value of an annuity for 2 years, 35 times the value of an annuity for 3 years, and so on—the last term being the value of 10 annuities for 86 years—and adding them together; and the value of an annuity on one of the nominees will then be found by dividing by 10,000. Before leaving the subject of De Witt, we may mention that we find in the correspondence a distinct suggestion of the law of mortality that bears the name of Demoivre. In De Witt's letter, dated 27 October 1671 (Ass. Mag. vol. iii. p. 107), he speaks of a "provisional hypothesis" suggested by Hudde, that out of 80 young lives (who, from the context, may be taken as of the age 6) about 1 dies annually. In strictness, therefore, the law in question might be more correctly termed Hudde's than Demoivre's.[6]

De Witt's report being thus of the nature of an unpublished state paper, although it contributed to its author's reputation, did not contribute to advance the exact knowledge of the subject; and the author to whom the credit must be given of first showing how to calculate the value of an annuity on correct principles is Edmund Halley. He gave the first approximately correct mortality table (deduced from the records of the numbers of deaths and baptisms in the city of Breslau), and showed how it might be employed to calculate the value of an annuity on the life of a nominee of any age.[7]

Previously to Halley's time, and apparently for many years subsequently, all dealings with life annuities were based upon mere conjectural estimates. The earliest known reference to any estimate of the value of life annuities rose out of the requirements of the Falcidian law, which in 40 B.C. was adopted in the Roman Empire, and which declared that a testator should not give more than three-fourths of his property in legacies, so that at least one-fourth must go to his legal representatives. It is easy to see how it would occasionally become necessary, while this law was in force, to value life annuities charged upon a testator's estate. Aemilius Macer (A.D. 230) states that the method which had been in common use at that time was as follows:--From the earliest age until 30 take 30 years' purchase, and for each age after 30 deduct 1 year. It is obvious that no consideration of compound interest can have entered into this estimate; and it is easy to see that it is equivalent to assuming that all persons who attain the age of 30 will certainly live to the age of 60, and then certainly die. Compared with this estimate, that which was propounded by the praetorian prefect Ulpian was a great improvement. His table is as follows:[6]

Here also we have no reason to suppose that the element of interest was taken into consideration; and the assumption, that between the ages of 40 and 50 each addition of a year to the nominee's age diminishes the value of the annuity by one year's purchase, is equivalent to assuming that there is no probability of the nominee dying between the ages of 40 and 50. Considered, however, simply as a table of the average duration of life, the values are fairly accurate. At all events, no more correct estimate appears to have been arrived at until the close of the 17th century.[6]

The mathematics of annuities has been very fully treated in Demoivre's Treatise on Annuities (1725); Simpson's Doctrine of Annuities and Reversions (1742); P. Gray, Tables and Formulae; Baily's Doctrine of Life Annuities; there are also innumerable compilations of Valuation Tables and Interest Tables, by means of which the value of an annuity at any age and any rate of interest may be found. See also the article interest, and especially that on insurance.[6]

Commutation tables, aptly so named in 1840 by Augustus De Morgan (see his paper "On the Calculation of Single Life Contingencies," Assurance Magazine, xii. 328), show the proportion in which a benefit due at one age ought to be changed, so as to retain the same value and be due at another age. The earliest known specimen of a commutation table is contained in William Dale's Introduction to the Study of the Doctrine of Annuities, published in 1772. A full account of this work is given by F. Hendriks in the second number of the Assurance Magazine, pp. 15–17. William Morgan's Treatise on Assurances, 1779, also contains a commutation table. Morgan gives the table as furnishing a convenient means of checking the correctness of the values of annuities found by the ordinary process. It may be assumed that he was aware that the table might be used for the direct calculation of annuities; but he appears to have been ignorant of its other uses.[6]

The first author who fully developed the powers of the table was John Nicholas Tetens, a native of Schleswig, who in 1785, while professor of philosophy and mathematics at Kiel, published in the German language an Introduction to the Calculation of Life Annuities and Assurances. This work appears to have been quite unknown in England until F. Hendriks gave, in the first number of the Assurance Magazine, pp. 1–20 (Sept. 1850), an account of it, with a translation of the passages describing the construction and use of the commutation table, and a sketch of the author's life and writings, to which we refer the reader who desires fuller information. It may be mentioned here that Tetens also gave only a specimen table, apparently not imagining that persons using his work would find it extremely useful to have a series of commutation tables, calculated and printed ready for use.[8]

The use of the commutation table was independently developed in England-apparently between the years 1788 and 1811—by George Barrett, of Petworth, Sussex, who was the son of a yeoman farmer, and was himself a village schoolmaster, and afterwards farm steward or bailiff. It has been usual to consider Barrett as the originator in England of the method of calculating the values of annuities by means of a commutation table, and this method is accordingly sometimes called Barrett's method. (It is also called the commutation method and the columnar method.) Barrett's method of calculating annuities was explained by him to Francis Baily in 1811, and was first made known to the world in a paper written by the latter and read before the Royal Society in 1812.[9]

By what has been universally considered an unfortunate error of judgment, this paper was not recommended by the council of the Royal Society to be printed, but it was given by Baily as an appendix to the second issue (in 1813) of his work on life annuities and assurances. Barrett had calculated extensive tables, and with Baily's aid attempted to get them published by subscription, but without success; and the only printed tables calculated according to his manner, besides the specimen tables given by Baily, are the tables contained in Babbage's Comparative View of the various Institutions for the Assurance of Lives, 1826.[9]

In 1825 Griffith Davies published his Tables of Life Contingencies, a work which contains, among others, two tables, which are confessedly derived from Baily's explanation of Barrett's tables.[9]

Those who desire to pursue the subject further can refer to the appendix to Baily's Life Annuities and Assurances, De Morgan's paper "On the Calculation of Single Life Contingencies," Assurance Magazine, xii. 348-349; Gray's Tables and Formulae chap. viii.; the preface to Davies's Treatise on Annuities; also Hendriks's papers in the Assurance Magazine, No. 1, p. 1, and No. 2, p. 12; and in particular De Morgan's "Account of a Correspondence between Mr George Barrett and Mr Francis Baily," in the Assurance Magazine, vol. iv. p. 185.[9]

The principal commutation tables published in England are contained in the following works:--David Jones, Value of Annuities and Reversionary Payments, issued in parts by the Useful Knowledge Society, completed in 1843; Jenkin Jones, New Rate of Mortality, 1843; G. Davies, Treatise on Annuities, 1825 (issued 1855); David Chisholm, Commutation Tables, 1858; Nelson's Contributions to Vital Statistics, 1857; Jardine Henry, Government Life Annuity Commutation Tables, 1866 and 1873; Institute of Actuaries Life Tables, 1872; R. P. Hardy, Valuation Tables, 1873; and Dr William Farr's contributions to the sixth (1844), twelfth (1849), and twentieth (1857) Reports of the Registrar General in England (English Tables, I. 2), and to the English Life Table, 1864.[9]

The theory of annuities may be further studied in the discussions in the English Journal of the Institute of Actuaries. The institute was founded in 1848, the first sessional meeting being held in January 1849. Its establishment has contributed in various ways to promote the study of the theory of life contingencies. Among these may be specified the following:--Before it was formed, students of the subject worked for the most part alone, and without any concert; and when any person had made an improvement in the theory, it had little chance of becoming publicly known unless he wrote a formal treatise on the whole subject. But the formation of the institute led to much greater interchange of opinion among actuaries, and afforded them a ready means of making known to their professional associates any improvements, real or supposed, that they thought they had made. Again, the discussions which follow the reading of papers before the institute have often served, first, to bring out into bold relief differences of opinion that were previously unsuspected, and afterwards to soften down those differences,--to correct extreme opinions in every direction, and to bring about a greater agreement of opinion on many important subjects. In no way, probably, have the objects of the institute been so effectually advanced as by the publication of its Journal. The first number of this work, which was originally called the Assurance Magazine, appeared in September 1850, and it has been continued quarterly down to the present time. It was originated by the public spirit of two well-known actuaries (Mr Charles Jellicoe and Mr Samuel Brown), and was adopted as the organ of the Institute of Actuaries in 1852, and called the Assurance Magazine and Journal of the Institute of Actuaries, Mr Jellicoe continuing to be the editor,--a post he held until the year 1867, when he was succeeded by Mr T. B. Sprague (who contributed to the 9th edition of this Encyclopaedia an elaborate article on "Annuities," on which the above account is based). The name was again changed in 1866, the words "Assurance Magazine" being dropped; but in the following year it was considered desirable to resume these, for the purpose of showing the continuity of the publication, and it is now called the Journal of the Institute of Actuaries and Assurance Magazine. This work contains not only the papers read before the institute (to which have been appended of late years short abstracts of the discussions on them), and many original papers which were unsuitable for reading, together with correspondence, but also reprints of many papers published elsewhere, which from various causes had become difficult of access to the ordinary reader, among which may be specified various papers which originally appeared in the Philosophical Transactions, the Philosophical Magazine, the Mechanics' Magazine, and the Companion to the Almanac; also translations of various papers from the French, German, and Danish. Among the useful objects which the continuous publication of the Journal of the institute has served, we may specify in particular two:--that any supposed improvement in the theory was effectually submitted to the criticisms of the whole actuarial profession, and its real value speedily discovered; and that any real improvement, whether great or small, being placed on record, successive writers have been able, one after the other, to take it up and develop it, each commencing where the previous one had left off.[9]
