Printable Version (including Fundamentals of Reinsurance)

-A-

Accident Year Experience - Reinsurance experience calculated by matching the total value of all losses occurring during a given twelve-month period (i.e., the dates of loss fall within the period) with the premiums earned for the same period. See also Calendar Year Experience and Policy Year Experience.

Acquisition Costs - All expenses directly related to acquiring insurance or reinsurance accounts, i.e., commissions paid to agents, brokerage fees paid to brokers, and expenses associated with marketing, underwriting, contract insurance and premium collection.

Admitted (Authorized) Reinsurance - Reinsurance for which credit is given in the ceding company's Annual Statement because the reinsurer is licensed or otherwise authorized to transact business in the jurisdiction in question.

Aggregate Excess of Loss Reinsurance - A form of excess of loss reinsurance which indemnifies the ceding company against the amount by which all of the ceding company's losses incurred during a specific period (usually 12 months) exceed either (1) a predetermined dollar amount or (2) a percentage of the company's subject premiums (loss ratio) for the specific period. This type of contract is also commonly referred to as "stop loss" reinsurance or "excess of loss ratio" reinsurance.

Alien - An insurer domiciled outside the United States.

Annual Statement (Also Statutory Annual Statement and Convention Blank) - The annual report format prescribed by the NAIC and the states.

Arbitration Clause - A provision found in many reinsurance contracts whereby the parties agree to submit their disputes to an unofficial tribunal of their own choosing rather than a court of law, generally subject to selection criteria and procedures set out in the clause, which produces an opinion ultimately enforceable by a court of law.

Assume - To accept all or part of a ceding company's insurance or reinsurance on a risk or exposure.

Assumption - A procedure under which one insurance company takes over or assumes the direct policy liabilities of another insurer.

Assumption of Liability Endorsement - A statement of coverage by the reinsurer under which payment is guaranteed to a party not in privity with the reinsurance contract.

Automatic Facultative Binder (AFB) or Automatic Facultative Treaty - See Facultative Treaty.

-B-

Base Premium - See Subject Premium.

Binder - A record of reinsurance coverage pending replacement by a formal reinsurance contract, usually a facultative certificate.

Bordereau - A report provided periodically by the reinsured detailing the reinsurance premiums and/or reinsurance losses with respect to specific risks ceded under the reinsurance agreement.

Broker - An intermediary who negotiates reinsurance contracts between the ceding company and the reinsurer(s). The broker generally represents the ceding company and receives a commission, almost always from the reinsurer(s), for placing the business and performing other necessary services.

Broker Market - The collective reference to those reinsurance companies which accept business mainly from reinsurance brokers. See Direct Writing Reinsurer.

Bulk Reinsurance - A transaction sometimes defined by statute as any quota share, surplus aid or portfolio reinsurance agreement through which, of itself or in combination with other similar agreements, an insurer assumes all or a substantial portion of the liability of the reinsured company.

Burning Cost - See Pure Loss Cost.

-C-

Calendar Year Experience - Reinsurance experience calculated by matching the total value of all losses incurred during a given twelve-month period ( regardless of the dates of loss) with the premiums earned for the same period. As the name implies, Calendar Year Experience is usually calculated for a twelve-month period beginning January 1st. Accident Year Experience and Policy Year Experience are related but not synonymous terms.

Capacity - The largest amount of insurance or reinsurance available from a company or the market in general. Also used to refer to the maximum amount of business (premium volume) which a company or the total market could write based on financial strength.

Catastrophe Reinsurance - A form of excess of loss reinsurance which, subject to a specific limit, indemnifies the ceding company in excess of a specified retention with respect to an accumulation of losses resulting from a catastrophic event or series of events arising from one occurrence. Catastrophe contracts can also be written on an aggregate basis under which protection is afforded for losses over a certain amount for each loss in excess of a second amount in the aggregate for all losses in all catastrophes occurring during a period of time (usually one year).

Cede - To transfer to a reinsurer all or part of the insurance or reinsurance risk written by a ceding company.

Ceding Commission - In calculating a reinsurance premium, an amount allowed by the reinsurer for part or all of a ceding company's acquisition and other overhead costs, including premium taxes. It may also include a profit factor. See Overriding Commission.

Ceding Company (Also Cedent, Reinsured, Reassured) - The insurer which cedes all or part of the insurance or reinsurance risk it has written to another insurer/reinsurer.

Cession - The amount of insurance risk transferred to the reinsurer by the ceding company.

Claims-Made Coverage - Any form of insurance under which the trigger of coverage is the presentation (or "making") of a claim against the insured rather than the date on which the loss occurred. A claims-made policy can provide for varying limitations as to the length of time prior to the policy period during which the loss event could have occurred (the "retroactive period") and the length of time after the policy has terminated during which the claim must be presented (the "tail" or "extended reporting period").

Clash Cover (or Contingency Cover) - An excess of loss reinsurance agreement with a retention level equal to or higher than the maximum limits written for any one reinsured policy or contract. Usually applicable to casualty lines of business, the clash cover is intended to protect the ceding company against accumulations of loss arising from multiple insureds and/or multiple lines of business for one insured involved in one loss occurrence.

Combination Plan Reinsurance - A reinsurance agreement which combines the excess of loss and the quota share forms of coverage within one contract, with the reinsurance premium established as a fixed percentage of the ceding company's subject premium. After deducting the excess recovery on any one loss for one risk, the reinsurer indemnifies the ceding company based on a fixed quota share percentage. If a loss does not exceed the excess of loss retention level, only the quota share coverage applies.

Commutation Agreement - An agreement between the ceding insurer and the reinsurer that provides for the valuation, payment and complete discharge of all obligations between the parties under particular reinsurance contract(s). Although more common where the ceding insurer or reinsurer has concerns about the other party's financial condition, commutation agreements can be used whenever the parties wish to settle and discharge all future obligations.

Commutation Clause - The clause in a reinsurance agreement which provides for the valuation, payment, and complete discharge of all obligations between the ceding company and the reinsurer, including future obligations for reinsurance losses incurred. The clause is most often found in workers compensation reinsurance contracts where future payments are of a continuous and generally known value.

Contingent Commission (Also Profit Commission) - A commission feature whereby the cedent is allowed a commission based on the reinsurer's profitability under the reinsurance contract.

Continuous Contract - A form of reinsurance contract for accepting new business which does not terminate automatically but rather is intended to continue from year to year unless one of the parties delivers notice of intent to discontinue or termination is mutually agreed to in accordance with the termination provisions of the contract.

Cover Note - A statement indicating that the coverage has been effected.

Credit for Reinsurance - A statutory accounting procedure permitting a ceding company to treat amounts due from reinsurers as assets or reductions from liability based on the status of the reinsurer.

Cut-Off (Also Clean-cut) - The termination provision of a reinsurance contract stipulating that the reinsurer shall not be liable for loss as a result of occurrences taking place after the date of termination.

Cut-Through Endorsement - An endorsement added to an insurance policy to provide that, in the event of the insolvency of the insurance company, the amount of any loss which would have been recovered from the reinsurer by the insurance company will be paid instead directly to the policyholder by the reinsurer. Also referred to as an Assumption of Liability Endorsement (ALE). See Guarantee Endorsement.

-D-

Deposit Premium - The amount of premium (usually for an excess of loss reinsurance contract) which the ceding company pays to the reinsurer on a periodic basis during the term of the contract. This amount is generally determined as a percentage of the estimated amount of premium which the contract will produce based on the rate and estimated subject premium. It is often the same as the Minimum Premium but may be higher or lower. The deposit premium will be adjusted to the higher of the actual developed premium or the minimum premium after the actual subject premium has been determined.

Direct Writing Reinsurer - A reinsurance company which develops its business by using its own personnel and does not (ordinarily) accept business from a broker or intermediary.

Drop-Down - See Second Event Retention.

Excess of Loss Reinsurance - A form of reinsurance which, subject to a specified limit, indemnifies the ceding company against the amount of loss in excess of a specified retention. It includes various types of a reinsurance, such as catastrophe reinsurance, per risk reinsurance, per occurrence reinsurance and aggregate excess of loss reinsurance. See also Non-Proportional Reinsurance.

Excess Per Risk Reinsurance - A form of excess of loss reinsurance which, subject to a specified limit, indemnifies the ceding company against the amount of loss in excess of a specified retention for each risk involved in each occurrence.

Experience Rating (Loss Rating, Merit Rating) - A method of rating under which the reinsurance rate is based upon the reinsured's own experience, actual or reconstructed, rather than upon the exposure inherent in the business. See also Retrospective Rating and Prospective Rating.

Exposure Rating - A method of rating, usually applied to excess of loss reinsurance, under which the rate is determined based on an analysis of the exposure inherent in the business to be covered and not on the loss experience the business has demonstrated in the past. Both exposure rating and loss rating can be used by the reinsurance underwriter to determine the price which is quoted.

Extra-Contractual Obligations (ECO) Clause - A clause in a reinsurance treaty which protects the ceding company against all or part of its liability arising from claim settlement activities and falling outside of strict policy provisions.

-F-

Facultative Certificate of Reinsurance - A contract formalizing a reinsurance cession on a specific risk.

Facultative Obligatory Treaty (Also Semi-obligatory Treaty) - A reinsurance contact under which the ceding company may cede exposures or risks of a defined class that the reinsurer must accept if ceded.

Facultative Treaty - A reinsurance contract under which the ceding company has the option to cede and the reinsurer has the option to accept or decline classified risks of a specific business line. The contract merely reflects how individual facultative reinsurance shall be handled.

Finite Reinsurance (Nontraditional Reinsurance, Limited Risk Reinsurance, and Financial Reinsurance) - A term used to describe a broad spectrum of treaty reinsurance arrangements which provide reinsurance coverage at lower margins than traditional reinsurance, in return for a lower probability of loss to the reinsurer. This reinsurance is often multi-year and financially oriented, and can provide a means of financial management beyond that usually provided by traditional reinsurance.

Fronting - Arrangements by which an authorized insurer, for a specified fee or premium, issues its policies to cover certain risks underwritten or otherwise managed by unauthorized insurers and then transfers all, or substantially all, of its liability to such unauthorized insurers by means of reinsurance.

Funds Withheld - A provision in a reinsurance treaty under which the premium due the reinsurer, usually an unauthorized reinsurer, is not paid but rather is withheld by the ceding company to enable the ceding company to reduce the provision for unauthorized reinsurance in its statutory statement. The reinsurer's asset, in lieu of cash, is "Funds held by or deposited with reinsured companies."

-G-

Gross Line - The total limit of liability accepted by an insurer on an individual risk (net line plus all reinsurance ceded).

Ground Up (From the) - A phrase referring to reinsurance losses subject to the contract under consideration before the application of the retention, but after reduction because of any other reinsurance which inures to the benefit of the coverage being considered. Also sometimes used to describe losses before reduction for inuring reinsurance.

Guarantee Endorsement - An endorsement added to an insurance policy covering the policyholder's mortgaged property to provide that, in the event of the insolvency of the insurance company, the reinsurer shall pay directly to the mortgagee and/or the policyholder the amount of loss which would have been recovered from the reinsurer by the insurance company. The endorsement may provide that the reinsurer will pay the full loss amount in accordance with the insurance protection afforded by the insurance company. The Guarantee Endorsement is also known as the Mortgagee Endorsement, and is similar in concept to the Cut-Through Endorsement.

-I-

Incurred But Not Reported (IBNR) - The loss reserve value established by insurance and reinsurance companies in recognition of their liability for future payments on losses which have occurred but which have not yet been reported to them. This definition is often erroneously expanded to include adverse loss development on reported claims; the term Incurred But Not Enough Reported (IBNER) is coming into increased usage to more accurately reflect the adverse development on inadequately reserved reported claims.

Indexing - A procedure sometimes incorporated into an excess of loss reinsurance treaty to adjust the retention and limit according to the value of a specified public economic index (for example: wage, price, or cost-of-living.)

Insolvency Clause - A contractual provision, generally required by statute or regulation as a prerequisite to receiving credit for reinsurance, under which the reinsurer agrees, in the event of the ceding insurer's insolvency, to pay its reinsurance obligations under the contract whether or not the insurer has paid its obligations.

Line Sheet (Also Line Guide) - A schedule showing the limits of liability to be written by a ceding company for different classes of risk and (usually) also showing the lines which can be ceded to proportional reinsurance treaties.

Loss Adjustment Expense (LAE) - The expense incurred by the ceding insurer in the defense and settlement of claims under its policies but not the insurer's overhead expenses. The definition of LAE depends on the terms of the reinsurance contract.

Loss Development - The difference between the estimated amount of loss(es) as initially reported to the reinsurer and the amount of an evaluation of the same loss(es) at a later date or the amount paid in final settlement(s).

Loss Loading or "Multiplier" (Also Loss Conversion Factor) - A factor is applied to the anticipated losses (or loss cost) for an excess of loss reinsurance agreement in order to develop the reinsurance premium (or rate.) This factor provides for the reinsurer's loss adjustment expense, overhead expense, and profit margin.

Loss Rating - A method of rating, usually applying to excess of loss reinsurance, under which the rate is determined based on the ceding insurer's historical loss experience, actual or reconstructed, rather than on the exposure inherent in the business. Both loss rating and exposure rating can be used as different rating approaches by the reinsurance underwriter to calculate the price which is quoted.

-M-

Minimum Premium - An amount of premium which will be charged (usually for an excess of loss reinsurance contract), notwithstanding that the actual premium developed by applying the rate to the subject premium could have produced a lower figure. See Deposit Premium.

Ninety Day Rule - The Annual Statement requirement which provides that an insurer must establish a provision for certain balances when it has reinsurance recoverables over ninety days past due.

No Claims Bonus - A form of profit commission under which the ceding company receives a stated percentage of the premium ceded in the event no claims are presented under the reinsurance treaty for a stipulated period of time. The no claims bonus differs from an ordinary profit commission in that no distribution occurs if any claims are made even if the treaty may have produced a profit.

Non-Admitted Reinsurance - Reinsurance for which no credit is given in the ceding company's statutory statement because the reinsurer is not licensed or authorized in the jurisdiction in question.

Non-Proportional Reinsurance - See Excess of Loss Reinsurance.

Payback - (1) A method of rating under which the underwriter sets the price based upon his view of how frequently the loss event might occur over a period of time. Thus, if the underwriter felt that the loss would occur only once in five years, the price would be set (without regard to expenses and profit margins) to be equal to the limit divided by five and the contract would thus be said to have a "five year payback." See also Rate on Line. (2) Can also refer to premium charged in addition to the cost of an ongoing program for prior losses and, thus "payback" reinsurers.

Placement Slip - A temporary record of reinsurance arrangements for which coverage has been effected, pending replacement by a formal reinsurance contract. Also known as a slip. See Binder.
