Incurred but not reported (IBNR)
Incurred but not reported loss reserves represent, Insured losses that have occurred but not reported to the primary insurance company. When a policy of insurance is written it will typically cover a defined period from inception of the policy. When the policy is sold, a premium is paid by the insured party to the insurer. The number and cost of claims that will arise from the policy are unknown and unknowable amounts at inception. Indeed, at expiry of the policy there can be a high degree of uncertainty as to what the cost of claims will ultimately be. There might be some information available on incurred claims amounts but this can often be zero.
These types of claims have a tremendous effect on reinsurance treaty,which may be showing a healthy profit when in reality it is losing money.Since the insurer knows neither how many of these losses (the frequency) have occurred, nor the severity of each loss, IBNR is necessarily an estimate.
The quality of this estimation is often used as a tool in assessing the financial accounting skills of a given insurer. Insurers track IBNR by policy periods along with other categorization's.Hence under the false security, the reinsurer will continue operating under a rating plan that is totally inadequate for the losses. This explains why a provision for IBNR losses should be made for rating plan. Also the reinsurer must establish an adequate reserve for IBNR claims to make a correct analysis of its business.
The insurer will conduct a reserving exercise with a view to assessing what this ultimate cost will be. This enables them to assess the profitability of the business that they have written and are planning to write in the future.This balancing item between the incurred claims and the ultimate claims is commonly referred to as the IBNR or the IBNR reserve. In pure terms, it only allows for those claims that have occurred before the valuation date but have not yet been reported to the insurer either directly or through the broker, hence the name. This pure usage is not used in practice. The more common usage includes reserves for items such as reopened claims, future claims on exposures to be written within the projection period, salvage .
The calculation of the IBNR reserve is a process that requires judgement and the results of which will remain uncertain for several years. The reserving process is typically done at an aggregate level. For example, at a class of business, underwriting year and currency level. It is important to try to achieve a homogeneous data grouping and to treat any special claims separately.
Such reserving calculations should be performed at a gross of reinsurance level and also for outwards proportional reinsurance and outwards excess of loss reinsurance separately.Reserving is increasingly undertaken by actuaries who are professionally qualified people. There are still a large number of statisticians with years of experience but no formal qualifications undertaking such work.
Typical reserving methods used to assess ultimate claims and hence IBNR reserves include:
* Incurred Chain Ladder
* Paid Chain Ladder
* Incurred Bornhuetter-Ferguson
* Paid Bornhuetter-Ferguson
* Exposure-based methods
These methods normally follows the Insurance Regulatory Authorities of their state government. Solvency I and Solvency II are the Regulatory Authorities for the European Union(The European Union (EU) is an economic and political union of 27 member states which are located primarily in Europe) .
First Solvency framework in the early 1970s, sophisticated risk management systems have been developed. Solvency II introduces a comprehensive framework for risk management for defining required capital levels and to implement procedures to identify, measure, and manage risk levels. Once the Omnibus II directive is approved by the European Parliament, Solvency II will be scheduled to come into effect on 1 January 2013.There is an exceptionally low degree of agreement within general insurance as to what much of the terminology actually means. IBNR is a widely accepted term with a fairly standard meaning.
