The chain-ladder technique is only accurate when patterns of loss development in the past can be assumed to continue in the future. [ 1 ] [ 3 ] [ 4 ] In contrast to other loss reserving methods such as the Bornhuetter–Ferguson method , it relies only on past experience to arrive at an incurred but not reported claims estimate.
Loss reserving is the calculation of the required reserves for a tranche of insurance business, [1] including outstanding claims reserves.. Typically, the claims reserves represent the money which should be held by the insurer so as to be able to meet all future claims arising from policies currently in force and policies written in the past.
Ultimate loss amounts are necessary for determining an insurance company's carried reserves. They are also useful for determining adequate insurance premiums, when loss experience is used as a rating factor [4] [5] [6] Loss development factors are used in all triangular methods of loss reserving, [7] such as the chain-ladder method.
For insurance, the loss ratio is the ratio of total losses incurred (paid and reserved) in claims plus adjustment expenses divided by the total premiums earned. [1] For example, if an insurance company pays $60 in claims for every $100 in collected premiums, then its loss ratio is 60% with a profit ratio/gross margin of 40% or $40.
Revenues and gross profit are recognized each period based on the construction progress, in other words, the percentage of completion. Construction costs plus gross profit earned to date are accumulated in an asset account (construction in process, also called construction in progress), and progress billings are accumulated in a liability account (billing on construction in process).
The Bornhuetter–Ferguson method was introduced in the 1972 paper "The Actuary and IBNR", co-authored by Ron Bornhuetter and Ron Ferguson. [4] [5] [7] [8]Like other loss reserving techniques, the Bornhuetter–Ferguson method aims to estimate incurred but not reported insurance claim amounts.
From this we can see that the present value of the loss to the insurance company now if the person dies in t years, is equal to the present value of the death benefit minus the present value of the premiums. The loss random variable described above only defines the loss at issue. For K(x) > t, the loss random variable at time t can be defined as:
