Actuaries Institute
An actuary is a professional with advanced mathematical skills who deals with the measurement and management of risk and uncertainty. These risks can affect both sides of the balance sheet and require asset management, liability management, and valuation skills. Actuaries provide assessments of financial security systems, with a focus on their complexity, their mathematics, and their mechanisms. The name of the corresponding academic discipline is actuarial science. While the concept of insurance dates to antiquity, the concepts needed to scientifically measure and mitigate risks have their origins in 17th-century studies of probability and annuities. Actuaries in the 21st century require analytical skills, business knowledge, and an understanding of human behavior and information systems; actuaries use this knowledge to design programs that manage risk, by determining if the implementation of strategies proposed for mitigating potential risks does not exceed the expected cos ...

Hurricane Katrina
Hurricane Katrina was a powerful, devastating and historic tropical cyclone that caused 1,392 fatalities and damages estimated at $125 billion in late August 2005, particularly in the city of New Orleans and its surrounding area. It is tied with Hurricane Harvey as being the List of the costliest tropical cyclones, costliest tropical cyclone in the Atlantic basin. Katrina was the twelfth tropical cyclone, the fifth hurricane, and the third major hurricane of the 2005 Atlantic hurricane season. It was also the fourth-most intense Atlantic hurricane to make landfall in the contiguous United States, gauged by barometric pressure. Katrina formed on August 23, 2005, with the merger of a tropical wave and the remnants of a tropical depression. After briefly weakening to a Tropical cyclone, tropical storm over south Florida, Katrina entered the Gulf of Mexico on August 26 and Rapid intensification, rapidly intensified to a Saffir–Simpson scale, Category 5 hurricane befo ...

Liability (financial Accounting)
In financial accounting, a liability is a quantity of value that a financial entity owes. More technically, it is value that an entity is expected to deliver in the future to satisfy a present obligation arising from past events. The value delivered to settle a liability may be in the form of assets transferred or services performed. Characteristics A liability is defined by the following characteristics: * Any type of borrowing from persons or banks for improving a business or personal income that is payable during short or long time; * A duty or responsibility to others that entails settlement by future transfer or use of assets, provision of services, or other transaction yielding an economic benefit, at a specified or determinable date, on occurrence of a specified event, or on demand; * A duty or responsibility that obligates the entity to another, leaving it little or no discretion to avoid settlement; and, * A transaction or event obligating the entity that has already occ ...

Disability Insurance
Disability Insurance, often called DI or disability income insurance, or income protection, is a form of insurance that insures the beneficiary's earned income against the risk that a disability creates a barrier for completion of core work functions. For example, the worker may be unable to maintain composure in the case of psychological disorders or sustain an injury, illness or condition that causes physical impairment or incapacity to work. DI encompasses paid sick leave, short-term disability benefits (STD), and long-term disability benefits (LTD). The same concept is instantiated in some countries as income protection insurance. History In the late 19th century, modern disability insurance began to become available. It was originally known as "accident insurance". The first company to offer accident insurance was the Railway Passengers Assurance Company, formed in 1848 in England to insure against the rising number of fatalities on the nascent railway system. It was regi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Life Annuity
A life annuity is an annuity, or series of payments at fixed intervals, paid while the purchaser (or annuitant) is alive. The majority of life annuities are insurance products sold or issued by life insurance companies. However, substantial case law indicates that annuity products are not necessarily insurance products. Annuities can be purchased to provide an income during retirement, or originate from a ''structured settlement'' of a personal injury lawsuit. Life annuities may be sold in exchange for the immediate payment of a lump sum (single-payment annuity) or a series of regular payments (flexible payment annuity), prior to the onset of the annuity. The payment stream from the issuer to the annuitant has an unknown duration based principally upon the date of death of the annuitant. At this point the contract will terminate and the remainder of the fund accumulated is forfeited unless there are other annuitants or beneficiaries in the contract. Thus a life annuity is a for ...

Life Insurance
Life insurance (or life assurance, especially in the Commonwealth of Nations) is a contract A contract is an agreement that specifies certain legally enforceable rights and obligations pertaining to two or more parties. A contract typically involves consent to transfer of goods, services, money, or promise to transfer any of thos ... between an insurance policy holder and an insurance , insurer or assurer, where the insurer promises to pay a designated beneficiary a sum of money upon the death of an insured person. Depending on the contract, other events such as terminal illness or critical illness can also trigger payment. The policyholder typically pays a premium, either regularly or as one lump sum. The benefits may include other expenses, such as funeral expenses. Life policies are legal contracts and the terms of each contract describe the limitations of the insured events. Often, specific exclusions written into the contract limit the liability of the insurer; c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morbidity Rate
In epidemiology, prevalence is the proportion of a particular population found to be affected by a medical condition (typically a disease or a risk factor such as smoking or seatbelt use) at a specific time. It is derived by comparing the number of people found to have the condition with the total number of people studied and is usually expressed as a fraction, a percentage, or the number of cases per 10,000 or 100,000 people. Prevalence is most often used in questionnaire studies. Difference between prevalence and incidence Prevalence is the number of disease cases ''present ''in a particular population at a given time, whereas incidence is the number of new cases that ''develop ''during a specified time period. Prevalence answers "How many people have this disease right now?" or "How many people have had this disease during this time period?". Incidence answers "How many people acquired the disease uring a specified time period". However, mathematically, prevalence is proport ...

Mortality Rate
Mortality rate, or death rate, is a measure of the number of deaths (in general, or due to a specific cause) in a particular Statistical population, population, scaled to the size of that population, per unit of time. Mortality rate is typically expressed in units of deaths per 1,000 individuals per year; thus, a mortality rate of 9.5 (out of 1,000) in a population of 1,000 would mean 9.5 deaths per year in that entire population, or 0.95% out of the total. It is distinct from "morbidity", which is either the prevalence or Incidence (epidemiology), incidence of a disease, and also from the incidence rate (the number of newly appearing cases of the disease per unit of time). An important specific mortality rate measure is the crude death rate, which looks at mortality from all causes in a given time interval for a given population. , for instance, the Central Intelligence Agency, CIA estimates that the crude death rate globally will be 7.7 deaths per 1,000 people in a population p ...

Pension
A pension (; ) is a fund into which amounts are paid regularly during an individual's working career, and from which periodic payments are made to support the person's retirement from work. A pension may be either a " defined benefit plan", where defined periodic payments are made in retirement and the sponsor of the scheme (e.g. the employer) must make further payments into the fund if necessary to support these defined retirement payments, or a " defined contribution plan", under which defined amounts are paid in during working life, and the retirement payments are whatever can be afforded from the fund. Pensions should not be confused with severance pay; the former is usually paid in regular amounts for life after retirement, while the latter is typically paid as a fixed amount after involuntary termination of employment before retirement. The terms " retirement plan" and " superannuation" tend to refer to a pension granted upon retirement of the individual; the terminolog ...

Social Security Administration
The United States Social Security Administration (SSA) is an Independent agencies of the United States government, independent agency of the Federal government of the United States, U.S. federal government that administers Social Security (United States), Social Security, a social insurance program consisting of retirement, disability and survivor benefits. The Social Security Administration was established by the Social Security Act of 1935 and is codified in (). It was created in 1935 as the "Social Security Board", then assumed its present name in 1946. Its current leader is Commissioner Frank Bisignano. SSA offers its services to the public through 1,200 field offices, a website, and a national toll-free number.

Government Actuary's Department
The Government Actuary's Department (GAD) provides actuarial solutions including risk analysis, modelling and advice to support the UK public sector. It is a department of the Government of the United Kingdom. History In 1912 the Government appointed a chief actuary to the National Health Insurance Joint Committee, following the Old Age Pensions Act 1908 and the National Insurance Act 1911 The National Insurance Act 1911 (1 & 2 Geo. 5. c. 55) created National Insurance, originally a system of health insurance for industrial workers in Great Britain based on contributions from employers, the government, and the workers themselves. .... As the role of the Chief Actuary expanded, the post of Government Actuary was created in 1917. The Government Actuary's Department was formed 2 years later. The role of GAD within government expanded significantly in the 1940s and 1950s, coinciding with an expansion of the state's role in pensions, social security and health care. By the 19 ...

Mathematical Statistics
Mathematical statistics is the application of probability theory and other mathematical concepts to statistics, as opposed to techniques for collecting statistical data. Specific mathematical techniques that are commonly used in statistics include mathematical analysis, linear algebra, stochastic analysis, differential equations, and measure theory. Introduction Statistical data collection is concerned with the planning of studies, especially with the design of randomized experiments and with the planning of surveys using random sampling. The initial analysis of the data often follows the study protocol specified prior to the study being conducted. The data from a study can also be analyzed to consider secondary hypotheses inspired by the initial results, or to suggest new studies. A secondary analysis of the data from a planned study uses tools from data analysis, and the process of doing this is mathematical statistics. Data analysis is divided into: * descriptive stati ...

Probability
Probability is a branch of mathematics and statistics concerning events and numerical descriptions of how likely they are to occur. The probability of an event is a number between 0 and 1; the larger the probability, the more likely an event is to occur."Kendall's Advanced Theory of Statistics, Volume 1: Distribution Theory", Alan Stuart and Keith Ord, 6th ed., (2009), .William Feller, ''An Introduction to Probability Theory and Its Applications'', vol. 1, 3rd ed., (1968), Wiley, . This number is often expressed as a percentage (%), ranging from 0% to 100%. A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes ("heads" and "tails") are both equally probable; the probability of "heads" equals the probability of "tails"; and since no other outcomes are possible, the probability of either "heads" or "tails" is 1/2 (which could also be written as 0.5 or 50%). These concepts have been given an axiomatic mathematical formaliza ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
