Why Create Claim Reserves A takaful is a legal contract in which the risk of loss occurring in a given period are covered and paid for by the takaful fund. For any given point in time during the contract, coverage must remain in force until the expiry date of the takaful contract For regulatory and prudential management purposes, it is essential that a quantification be done of the monetary amount a takaful contract is still ‘on risk’ at a given point in time ‘Amount on Risk’ at a given point in time is known as the provision for claims or claims liability.

Why Create Claim Reserves Hence Operator have to determine the following: What is the takaful claims reserves/liability at a given date? What is the excess of takaful fund assets over liabilities (i.e. surplus) of the takaful fund? [this will be of interest to participants (and operator) who may have a share in the underwriting surplus] What is the profit generated for the year up to the given date? (If operator revenue is also derived from a share of underwriting surplus then obviously claims reserving will have an important impact on operator revenue and profit)

Reserving in General Takaful Additional questions:- Is there a possibility that claims may have been reported to ABC but the payments have yet to be paid from the takaful fund. Such claims which have occurred but have not been paid yet should be provided for. There is also the possibility that claims have occurred but those claims have yet to be reported. These incurred but not reported claims represent a liability as well to the takaful fund. As at valuation date, there is also the remaining unexpired contract period of coverage to expiry date in which claims can still arise.

Reserving in General Takaful Claim Reserves comprise: a provision for claims which may occur in the remaining period to expiry of the takaful contract – this is also known as the claims provision or reserve for unexpired risk; plus a provision for claims already occurred – this is also known as the claims provision or reserve for outstanding claims made up of: A provision for claims occurred and reported but not yet paid A provision for claims occurred but not yet reported also known as provisions for claims Incurred But Not Reported (IBNR)

Reserving in General Takaful Unexpired Contribution Reserve ( at reserve valuation date ) = Contribution x (1-E) x Unexpired Contract Period Original Contract Duration Where E = margin for operator expenses Additional Unexpired Risk Reserve (AURR) which is the reserve held in excess of the unearned contribution reserve for unexpired risks.

Claims Estimation in General Takaful The outstanding claims reserve would largely consist of the sum total of individual claims estimates in respect of all outstanding claims as at a given accounting or reserve valuation date. Individual claims estimation which is typically carried out by the claims department of a takaful operator would require assumptions as to : the severity of the claim the time taken to final claims settlement the rate of inflation on claims costs between the accounting date and settlement trends in the court system with respect to court awards in relation to settlement of liability claims, etc

Claim Estimation Methods in General Takaful Claim run-off analysis is the technique of triangulating claims The technique requires basic claims settlement data to be tracked or sorted by year of claim since the original year of claims occurrence or issue of coverage. The analysis may be in terms of claim numbers or claim amounts.

Claim Estimation Method in General Takaful The Chain Ladder Method (also known as the linked ratio method) is based on extrapolating claims using the above claims triangulation table. A major assumption of the Chain Ladder method is that the pattern of claims delay over time is not affected by external factors such as inflation which will cause claims to increase over time or changes in the underlying risk or mix of takaful business. Given such stability we can work out ratios of claims buildup from one development year (year claim is paid) to the next and use the ratios to project claims for all years of issue.

Possible Claims Development Factors Year of Issue From Year to Year

Chain Ladder Method Example As at 2007 end the estimated outstanding reserves for 2003 is $5,000. Based on the previous paid claims triangulation data and 2003 estimate, calculate the estimated outstanding claims as at 2007 for issue years 2004, 2005, 2006 and Ultimate cumulative claims in respect of 2003 year of issues =2003 cumulative estimated reserves =190, ,000 =195,000

The furthermost data we have on ultimate claims (projected cumulative) developing is for claims arising in year 4 which is in respect of the claims arising from 2003 year of issues. These are the cumulative claims paid up to 2007 plus any estimate of outstanding claims as at end of 2007 which originate from year of issue Claims Development factor from development year 3 to year 4 for issue year 2003; M3,4 = ultimate claims in respect of development year 4 Claims in development year 3 = 190, ,000 = ,000 Calculation of Claims Development Factors

Claims development factor from year 2 to year 3 for issue years 2003 and 2004; M2,3 = Total Cumulative Claims in development year 3 Total cumulative Claims in development year 2 = (180, ,000)= (450,000) = , , ,000 Claims development factor from year 1 to year 2 for issue years 2003, 2004 and 2005; M1,2 = Total Cumulative Claims in development year 2 Total Cumulative Claims in development year 1 = (160, , ,000)= (720,000) = , , , ,000 Calculation of Claims Development Factors

If the claims statistics used includes claims which are reported late, then this method of estimating claims outstanding implicitly includes a provision for IBNR claims;

Other Claim Estimation Method in General Takaful Relatively easy to compute given but the main drawback to the method lies in its assumption that the patterns of claims amount paid over time are relatively stable. Another key ingredient of traditional chain ladder methods is that sufficient claims statistics exist in order to triangulate claims and thereby build claims development factors. The Bornhuetter Ferguson Method may be used where claims data is not available. Ultimate losses projected based on an expected average claim size or an expected loss ratio. Usually an expected loss ratio based on industry statistics is used for projection of ultimate losses. Providing for claims handling expense especially in respect of long tail claims where the expense of handling claims may stretch over many years also need to be made.

Reserving in Family Takaful As the life (family) takaful fund is typically made up of two funds, liability provisioning will need to be done for each of the funds. Due to the long term nature of many life (family) takaful products, an expected annual rate of profit from money invested over time is typically incorporated into the liability provisioning (reserving) calculation The liability provision for the savings fund just involve the adding up of the balances in each of the participants’ accounts ( same way a bank would account for the monies held in bank deposit accounts placed by individual depositors).

Reserving in Family Takaful For life (family) takaful products in particular, the liability provisioning or reserving process would need to take into account the duration of coverage provided under the product and the nature of contributions charged to finance the benefit For example, a family (life) takaful plan which provides decreasing term takaful coverage (e.g. MRTT for house financing) over 10 years based on a single contribution would obviously have a pattern of liability that will be probably be highest at point of plan inception and then decline over time until contract expiry.

Reserving in Family Takaful The pattern of liability will differ greatly depending on the nature of renewability, the point being that a plan with guaranteed coverage or renewability over an extended period of time will carry a much higher liability risk profile compared to a plan with shorter term coverage or renewability. For example, if the coverage of a plan is annually renewable then the takaful fund is technically only on risk for a year at a time. On each contract renewal date, the contract may be revised and repriced to reflect the risks covered and ascertained at that renewal date.

Reserving in Family Takaful The liability calculation for longer term takaful plans in the takaful risk fund would need to incorporate the opportunity cost of cash flows over future years and hence, discounting the expected benefit payment using an assumed investment profit rate forms part of the valuation process. t V x = A x+t – Cont.x a x+t

Regulations on Reserving The regulator usually requires an assumption of mortality that was heavier (i.e. higher probability) than that assumed in pricing the product. For solvency/statutory purposes where the assumptions incorporate additional margins such that the reserves so calculated would usually be more than sufficient to meet claims to a high degree of certainty. It is possible to find fund deficits occurring merely as a result of the difference between the pricing basis and the valuation basis.

ISSUES Valuation centers on the timing of income recognition in the accounts and ensuring liabilities are set up accordingly. Conceptually reserving practices would be similar to conventional insurers, with a few special concerns:- To ensure that investment assumptions are reasonable; considering Wakala and Mudharaba profit sharing

ISSUES (…contd) Need to build up contingency /claims stabilization reserves Depending on the model some surplus may be held back in a contingency reserves to act as a buffer for adverse experience (solvency margin)
