IFoA SA4 key terms

A group of members at Lloyd's that pools capital to underwrite a defined portfolio of insurance risks for a single underwriting year, operating under Lloyd's oversight and relying on the market's central guarantee chain.

A firm granted underwriting authority by an insurer or Lloyd's syndicate, often handling pricing, binding and claims while the capacity provider retains the risk and regulatory capital burden.

A contractual arrangement in which an insurer gives another party permission to act on its behalf, typically for underwriting, claims handling or distribution, within written limits and controls.

The documented scope within which an agent may accept risks for an insurer, specifying classes, limits, exclusions, pricing rules and reporting obligations.

The recurring pattern in general insurance where periods of soft pricing and loose terms are followed by capital erosion, capacity withdrawal and hardening rates, driven by competition and loss experience.

A phase of the underwriting cycle in which abundant capacity and competition push premiums down and coverage terms widen, often masking deteriorating underlying loss trends.

A phase of the underwriting cycle in which capacity shrinks and insurers raise rates, tighten terms and restrict coverage, usually following poor results or a major catastrophe.

The risk-based prudential regime for European insurers, built on three pillars covering quantitative capital requirements, governance and supervision, and disclosure, with prescribed valuation and reporting standards.

The capital an insurer must hold to absorb a one-in-200-year adverse shock over one year, calculated by a prescribed standard formula or an approved internal model.

A lower capital floor below which supervisory intervention is triggered, calculated more simply than the solvency capital requirement and subject to absolute bounds.

An insurer's own forward-looking assessment of the risks it faces and the capital needed over its business planning horizon, documented and submitted for supervisory review.

A firm-built framework for quantifying risk and capital, calibrated to a stated confidence level, which must be approved by the supervisor before it can be used in regulatory capital calculations.

The amount an insurer must hold to meet its insurance obligations, comprising a best estimate of future cash flows plus a risk margin for non-hedgeable risk.

The probability-weighted present value of expected future claim payments, expenses and premiums, using assumptions that reflect current experience without deliberate prudence.

An addition to the best estimate in regulatory technical provisions, representing what another insurer would require to take on the obligations, often computed by a cost-of-capital method.

The risk that future claims and expenses on business not yet written, or written but not yet earned, exceed the premiums charged, including reserve risk on unexpired exposure.

The risk that provisions for claims already incurred prove inadequate because actual settlements differ from the assumptions used at valuation, including latent and development uncertainty.

The risk of severe loss from a single event or accumulation of events, such as a windstorm, flood or earthquake, modelled with frequency-severity and exposure data.

The concentration of exposure to loss from one event or common cause across policies, locations or lines, which must be monitored and controlled to avoid excessive single-event losses.

An estimate of the largest loss expected from a defined event at a stated probability level, used to size reinsurance purchases and monitor catastrophe exposure.

A table of cumulative paid or incurred claims by accident period and development period, used to estimate patterns of claim emergence and project ultimate costs.

A reserving technique that derives age-to-age development factors from historical triangles and applies them to cumulative claims to project ultimate losses.

A reserving approach blending an expected loss ratio with observed development, giving weight to the prior expectation for immature periods where reported claims are unreliable.

The ratio of projected ultimate losses to earned premium, often set from pricing assumptions or benchmark data and used as a prior in reserving and planning.

An amount set aside for an individual reported claim based on the claims handler's assessment of likely ultimate cost, reviewed as the claim develops.

Provisions for claims that have occurred but not yet been reported to the insurer, plus development on reported claims beyond current case estimates.

A proportional treaty in which the reinsurer accepts a fixed percentage of every risk within scope, sharing premium and losses in that same proportion.

A proportional treaty in which the insurer retains a fixed amount per risk and cedes the excess above it, allowing retention to vary with risk size.

A non-proportional treaty under which the reinsurer pays losses above an agreed retention up to a limit, for either individual risks or a catastrophe event.

The loss or retention level at which a reinsurance layer begins to respond, above which the reinsurer pays until the layer limit is exhausted.

The historical ratio of reinsured losses to subject premium, used as a starting point for pricing non-proportional reinsurance before loading for expenses, profit and trend.

Total premium written by an insurer before deducting reinsurance ceded, reflecting the full volume of business accepted in a period.

Premium attributable to the portion of cover provided in a period, after deducting reinsurance ceded and adjusting for unearned premium movements.

The portion of written premium relating to cover not yet provided at the reporting date, held as a liability and released as the policy period elapses.

The sum of the loss ratio and expense ratio, where a value below 100% indicates an underwriting profit before investment income.

Incurred losses divided by earned premium for a period, a core measure of underwriting performance that can be distorted by reserve movements.

Underwriting expenses divided by written or earned premium, capturing acquisition costs and administrative overheads attributable to insurance operations.

The amount and type of risk an insurer is willing to accept in pursuit of its objectives, expressed through qualitative statements and quantitative tolerances.

The specific quantitative limits or thresholds that translate risk appetite into operational constraints, such as maximum capital at risk from a single event.

A governance model in which operational management owns risk, a separate risk and compliance function oversees it, and internal audit provides independent assurance.

Independent assessment of whether a model is conceptually sound, appropriately calibrated and fit for its intended use, including back-testing and review of limitations.

The professional standards issued by the IFoA setting out principles of integrity, competence, communication and accountability that members must follow in their work.

Standards issued by the Financial Reporting Council specifying how actuarial work in regulated areas must be documented, communicated and supported by evidence.

The reasoned selection among alternative assumptions or methods, supported by evidence and analysis, and documented so that another actuary could review and challenge it.

A situation where an actuary's other interests or relationships could improperly influence professional advice, requiring disclosure and appropriate management.

Raising a concern, internally or with a regulator, about conduct or practice that may breach professional standards or law, protected under the Actuaries' Code.
