An
actuary is a
business professional who deals with the financial impact of risk and uncertainty. Actuaries are experts in financial security systems, their reasons for being, their complexity, and their mathematics . They evaluate the likelihood of events and quantify the contingent outcomes in order to minimize losses, both emotional and financial, associated with uncertain undesirable events. Since many events, such as death, cannot be totally avoided, measures must be taken to minimize their financial impact when they occur. These risks can impact both sides of the balance sheet and require asset management, liability management, and valuation skills. Analytical skills, business knowledge and understanding of both human behavior and the vagaries of information systems are required to design and manage programs that control risk .
Actuaries' insurance disciplines may be classified as life, health, pensions, annuities, and asset management, social welfare programs, property, casualty, liability, general insurance and reinsurance. Life, health, and pension actuaries deal with
mortality risk, morbidity, and consumer choice regarding the ongoing utilization of drugs and medical services risk, and investment risk. Products prominent in their work include life insurance, annuities, pensions, mortgage and credit insurance, short and long term
disability, and medical, dental, health savings accounts and long term care insurance. In addition to these risks, social insurance programs are greatly influenced by public opinion, politics, budget constraints, changing demographics and other factors such as medical technology, inflation and cost of living considerations .
Casualty actuaries, also known as non-life or general insurance actuaries, deal with catastrophic, unnatural risks that can occur to people or property. Products prominent in their work include
auto insurance, homeowners insurance, commercial property insurance, workers’ compensation, title insurance, malpractice insurance, products liability insurance, directors and officers liability insurance, environmental and marine insurance, terrorism insurance and other types of liability insurance. Reinsurance products have to accommodate all of the previously mentioned products, and in addition have to properly reflect the increasing long term risks associated with cultural litigiousness,
acts of war,
terrorism and politics .
In 2002, a
Wall Street Journal is an influential international daily newspaper [i] published in New York City [i] ...
survey on the best jobs in the United States listed actuary as the second best job, while in previous editions of the list, actuaries had been the top rated job .
History
Need for insurance
The basic requirements of communal interests gave rise to risk sharing since the dawn of civilization. For example, people who lived their entire lives in a camp had the risk of fire, which would leave their band or family without shelter. As more complex forms of exchange developed beyond barter, new forms of risk manifested. Merchants embarking on trade journeys bore the risk of losing goods entrusted to them, their own possessions, or even their lives. Intermediaries developed to warehouse and trade goods, and they often suffered from financial risk. The primary providers in any extended families or household always ran the risk of premature death, disability or infirmity, leaving their dependents to starve. Credit procurement was difficult if the lender worried about repayment in the event of the borrower's death or infirmity. Alternatively, people sometimes lived too long, exhausting their savings, if any, or becoming a burden on others in the extended family or society .
Early attempts
In the ancient world there was no room for the sick, suffering, disabled, aged, or the poor—these were largely not part of the cultural consciousness of societies . Early methods of protection involved charity; religious organizations or neighbors would collect for the destitute and needy. By the middle of the
third century, 1,500 suffering people were being supported by charitable operations in
Rome . Charitable protection is still an active form of support to this very day . However, receiving charity is uncertain and is often accompanied by social stigma. Elementary mutual aid agreements and pensions did arise in antiquity . Early in the
Roman empire, associations were formed to meet the expenses of burial, cremation, and monuments—precursors to burial insurance and friendly societies. A small sum was paid into a communal fund on a weekly basis, and upon the death of a member, the fund would cover the expenses of rites and burial. These societies sometimes sold shares in the building of
columbaria, or burial vaults, owned by the fund—the precursor to mutual insurance companies . Other early examples of mutual surety and assurance pacts can be traced back to various forms of fellowship within the Saxon clans of England and their Germanic forbears, and to Celtic society . However, many of these earlier forms of surety and aid would fail due to lack of understanding and knowledge .
Development of theory
The
seventeenth century was a period of extraordinary advances in mathematics in Germany, France and England. At the same time there was a rapidly growing desire and need to place the valuation of personal risk on a more scientific basis. Independently from each other, compound interest was studied and probability theory emerged as a well understood mathematical discipline. Another important advance came in 1662 from a London draper named John Graunt, who showed that there were predictable patterns of longevity and death in a defined group, or cohort, of people, despite the uncertainty about the future longevity or mortality of any one individual person. This study became the basis for the original
life table. It was now possible to set up an insurance scheme to provide life insurance or pensions for a group of people, and to calculate with some degree of accuracy how much each person in the group should contribute to a common fund assumed to earn a fixed rate of interest. The first person to demonstrate publicly how this could be done was
Edmond Halley. In addition to constructing his own life table, Halley demonstrated a method of using his life table to calculate the premium someone of a given age should pay to purchase a life-annuity .
Early actuaries
James Dodson’s pioneering work on the level premium system led to the formation of the Society for Equitable Assurances on Lives and Survivorship in London in 1762. This was the first life insurance company to use premium rates which were calculated scientifically for long-term life policies, using Dodson’s work. The company still exists, though it has run into difficulties recently. After Dodson’s death in 1757, Edward Rowe Mores took over the leadership of the group that eventually became the Society for Equitable Assurances in 1762. It was he who specified that the chief official should be called an ‘actuary’ . Previously, the use of the term had been restricted to an official who recorded the decisions, or ‘acts’, of ecclesiastical courts, in ancient times originally the secretary of the
Roman senate, responsible for compiling the Acta Senatus . Other companies which did not originally use such mathematical and scientific methods most often failed or were forced to adopt the methods pioneered by Equitable .
Development of the modern profession
In the
eighteenth and
nineteenth centuries, computational complexity was limited to manual calculations. The actual calculations required to compute fair insurance premiums are rather complex. The actuaries of that time developed methods to construct easily-used tables, using sophisticated approximations called commutation functions, to facilitate timely, accurate, manual calculations of premiums . Over time, actuarial organizations were founded to support and further both actuaries and
actuarial science, and to protect the public interest by ensuring competency and ethical standards . However, calculations remained cumbersome, and actuarial shortcuts were commonplace. Non-life actuaries followed in the footsteps of their life compatriots in the early
twentieth century. The 1920 revision to workers compensation rates took over two months of around-the-clock work by day and night teams of actuaries . In the 1930s and 1940s, however, rigorous mathematical foundations for stochastic processes were developed . Actuaries could now begin to forecast losses using models of random events instead of deterministic methods. Computers further revolutionized the actuarial profession. From pencil-and-paper to punchcards to microcomputers, the modeling and forecasting ability of the actuary has grown exponentially .
Another modern development is the convergence of modern financial theory with actuarial science . In the early twentieth century, actuaries were developing many techniques that can be found in modern financial theory, but for various historical reasons, these developments did not achieve much recognition . However, in the late 1980s and early 1990s, there was a distinct effort for actuaries to combine financial theory and stochastic methods into their established models . Today, the profession, both in practice and in the educational syllabi of many actuarial organizations, combines tables, loss models, stochastic methods, and financial theory , but is still not completely aligned with modern financial economics.
Responsibilities
Actuaries use skills in
mathematics,
economics,
finance, probability and
statistics, and
business to help businesses assess the risk of certain events occurring, and to formulate policies that minimize the cost of that risk. For this reason, actuaries are essential to the insurance and reinsurance industry, either as staff employees or as consultants, as well as to government agencies such as the Government Actuary’s Department in the UK or the
Social Security Administration in the US. Actuaries assemble and analyze data to estimate the probability and likely cost of the occurrence of an event such as death, sickness, injury, disability, or loss of property. Actuaries also address financial questions, including those involving the level of pension contributions required to produce a certain retirement income and the way in which a company should invest resources to maximize its return on investments in light of potential risk. Using their broad knowledge, actuaries help design and price insurance policies, pension plans, and other financial strategies in a manner which will help ensure that the plans are maintained on a sound financial basis .
Traditional employment
On both the life and casualty sides, the classical function of actuaries is to calculate premiums and reserves for insurance policies covering various risks. Premiums are the amount of money the insurer needs to collect from the policyholder in order to cover the expected losses, expenses, and a provision for profit. Reserves are provisions for future liabilities and indicate how much money should be set aside now to reasonably provide for future payouts. If you inspect the balance sheet of an insurance company, you will find that the liability side consists mainly of reserves.
On the casualty side, this analysis often involves quantifying the probability of a loss event, called the frequency, and the size of that loss event, called the severity. Further, the amount of time that occurs before the loss event is also important, as the insurer will not have to pay anything until after the event has occurred. On the life side, the analysis often involves quantifying how much a potential sum of money or a financial liability will be worth at different points in the future. Since neither of these kinds of analysis are purely deterministic processes, stochastic models are often used to determine frequency and severity distributions and the
parameters of these distributions. Forecasting interest yields and currency movements also plays a role in determining future costs, especially on the life side.
Actuaries do not always attempt to predict aggregate future events. Often, their work may relate to determining the cost of financial liabilities that have already occurred, called retrospective reinsurance, or the development or re-pricing of new products.
Actuaries also design and maintain products and systems. They are involved in financial reporting of companies’ assets and liabilities. They must communicate complex concepts to clients who may not share their language or depth of knowledge. Actuaries work under a strict code of ethics that covers their communications and work products, but their clients may not adhere to those same standards when interpreting the data or using it within different kinds of businesses.
Non-traditional employment
Many actuaries are general business managers or financial officers. They analyze prospective business prospects with their financial skills in valuing or discounting risky future cash flows, and many apply their pricing expertise from insurance to other lines of business. Some actuaries act as expert witnesses by applying their analysis in court trials to estimate the economic value of losses such as lost profits or lost wages.
There has been a recent widening of the scope of the actuarial field to include investment advice and asset management. Further, there has been a convergence from the financial fields of risk management and quantitative analysis with
actuarial science. Now, actuaries also work as risk managers, quantitative analysts, or investment specialists. Even actuaries in traditional roles are now studying and using the tools and data previously in the domain of finance .
Remuneration
The credentialing and examination procedure for becoming a fully qualified actuary can be discouraging. Consequently, the profession remains very small throughout the world. As a result, actuaries are in high demand, and they are highly paid for the services they render . In the UK, where there are approximately 8,000 fully qualified actuaries, typical starting salaries range between
GBP £24,000 and £30,000 and newly qualified actuaries in insurance companies earn somewhere between £44,000 and £64,000 per year. Many successful actuaries earn over £100,000 a year .
In developing markets such as
India, annual compensation for newly qualified actuaries starts at around 8 lakh and can go as high as 20 lakh .
Credentialing and exams
Becoming a fully credentialed actuary requires passing a rigorous series of exams, usually taking several years. In some countries, such as France, most study takes place in a university setting. In others, such as the U.S. and the UK, most study takes place during employment.
UK and Republic of Ireland
Qualification in the
United Kingdom and the
Republic of Ireland consists of a combination of exams and courses provided by the professional bodies, the Institute of Actuaries based in
London,
England, and the Faculty of Actuaries based in
Edinburgh,
Scotland—separate but coinciding bodies. No geographic limitations exist for these bodies. Students and actuaries in any part of the UK or the Republic of Ireland may be a member of either or both bodies. The exams may only be taken upon having officially joined the body, unlike many other countries where exams may be taken earlier. However, a candidate may offer proof of having previously covered topics, usually while at university, in order to be exempt from taking certain subjects. The exams themselves are split into four sections: Core Technical , Core Applications , Specialist Technical , and Specialist Applications . In addition to exams and courses, it is required that the candidate have at least three years' experience of actuarial work under supervision of a recognized actuary for him or her to qualify as a “Fellow of the of Actuaries” .
United States
In the U.S., for life and health actuaries, exams are given by the
Society of Actuaries, while for property and casualty actuaries the exams are administered by the
Casualty Actuarial Society. The Society of Actuaries’ membership requirements include passing six examinations for Associateship, and an additional two exams, together with the completion of a professional paper, for Fellowship . The Casualty Actuary Society requires the successful completion of seven examinations for Associateship and two additional exams for Fellowship. In addition to these requirements, casualty actuarial candidates must also complete professionalism education and be recommended for membership by existing members . Continuing education is required after certification for all actuaries.
In order to sign statements of actuarial opinion, however, American actuaries must be members of the
American Academy of Actuaries. Academy membership requirements include membership in one of the recognized actuarial societies, at least three years of full-time equivalent experience in responsible actuarial work, and either residency in the United States for at least three years or a non-resident or new resident who meets certain requirements .
Canada
The Canadian Institute of Actuaries, or the CIA, recognizes fellows of both the Society of Actuaries and the Casualty Actuary Society, provided that they have specialized study in Canadian actuarial practice. For fellows of the SOA, this is fulfilled by taking the CIA’s Practice Education Course . For fellows of the Casualty Actuarial Society, this is fulfilled by taking exam 7C instead of exam 7US. Unlike their American counterparts, the CIA only has one class of actuary—Fellow. Further, the CIA requires three years of actuarial practice within the previous decade, and 18 months of Canadian actuarial practice within the last three years, to become a fellow .
Sweden
Actuarial training
Sweden takes place at
Stockholm University. The four year master's program covers the subjects
mathematics,
mathematical statistics,
insurance mathematics, financial mathematics, insurance
law and insurance
economics. The program operates under the Division of Mathematical Statistics .
Other countries
Many other countries pattern their requirements after the larger societies of the US or UK. In general, the websites of these organizations are often the easiest source for finding out about membership requirements.
Exam support
As these qualifying exams are rigorous, support is usually available to people progressing through the exams. Often, employers provide paid on-the-job study time and paid attendance at seminars designed for the exams . Also, many companies which employ actuaries have automatic pay raises or promotions when exams are passed. As a result, actuarial students have strong incentives for devoting adequate study time during off-work hours. A common rule of thumb for exam students is to put in roughly 400 hours of study time per full exam taken . Thus, several thousands of hours of study time should be anticipated over several years, assuming no failures . In practice, as the historical passing percentages remain below 50% for these exams, the “travel time” to credentialing is extended and more study time is needed. This process resembles formal schooling, so that actuaries who are sitting for exams are still called “students” or “candidates” despite holding important positions with substantial responsibilities.
Notable actuaries
;
Edmond Halley :While Halley actually predated much of what is now considered the start of the actuarial profession, he was the first to mathematically and statistically rigorously calculate premiums for a life insurance policy .
;Edward Rowe Mores :First person to use the title ‘actuary’ with respect to a business position .
;William Morgan :Morgan was the appointed Actuary of the Society for Equitable Assurances in 1775. He expanded on Mores's and Dodson's work, and may be rightly considered the father of the actuarial profession in that his title became applied to the field as a whole..
;Isaac M. Rubinow :Founder and first president of the
Casualty Actuarial Society .
Fictional actuaries
Due to the low public-profile of the job, two of the most recognisable actuaries to the general public happen to be characters in movies. Many actuaries were unhappy with the stereotypical portrayals of these actuaries as unhappy, math-obsessed and socially inept people; others have claimed that the portrayals are close to home, if a bit exaggerated. .
;Warren Schmidt: Warren is portrayed by
Jack Nicholson and is from the movie
About Schmidt. The movie mostly covers Schmidt's retirement from an insurance company. Schmidt is portrayed as antisocial and unfriendly. He does not want to retire and spends his free time still working on actuarial calculations.
