Annual Reset and Risk Period
Definition
A cat bond's risk period is the time during which covered events can trigger it, often three or four years split into annual risk periods. An annual reset recalculates the bond's attachment level, exhaustion level and related terms at the start of each annual period using the sponsor's updated exposure data, so that the modeled risk stays within agreed bounds as the sponsor's book changes.
Why it matters
A reset keeps a multi-year bond's risk close to what investors priced as the sponsor's portfolio grows or shrinks, and it moves the attachment point in dollars. Investors should know whether the spread also resets, what bounds limit the modeled expected loss, and who performs the calculation.
Common misconceptions
- •A multi-year bond does not lock the attachment point for its whole term if it resets.
- •A reset is not a renegotiation; it follows a formula and a reset agent's calculation.
- •The risk period and the maturity are not the same; extensions can follow the risk period.
- •The label is only a starting point. Investor outcomes usually depend on the governing documents, cash-flow priority, valuation policy, disclosure quality, and manager discretion surrounding the term, not just the shorthand definition used in marketing materials.
Technical details
Reset mechanics in Purple Re 2023-1 (Article XI)

How investors apply the term
Investors usually apply this term by tying the definition back to the controlling documents and then asking which cash flows, rights, restrictions, or valuation assumptions it changes. A useful review looks at the term alongside fees, leverage, liquidity, reporting frequency, and manager discretion rather than treating it as a standalone concept.
The practical diligence test is simple: identify who benefits if the assumption is wrong, who has control when conditions change, and what evidence the investor receives after closing. Terms that cannot be reconciled to documents, cash movements, and monitoring data should be treated as marketing shorthand until proven otherwise.
Frequently asked questions
- How does a reset work?
- In Slide Insurance's 2023 Purple Re Ltd. agreement, an independent reset agent uses the cedent's updated data and the agreed escrow models to reset 'the Attachment Level, the Exhaustion Level and the Insurance Percentage' each annual risk period. The cedent may also elect a variable reset within limits, provided the layer's modeled one-year expected loss stays between stated minimum and maximum levels.
- Why would a sponsor worry about a reset?
- Because the attachment point can move. Palomar's 2019 S-1 said its Torrey Pines Re bond 'is subject to an annual reset mechanism that determines the attachment point of the coverage,' which 'may fluctuate from year to year which could result in a gap in coverage.'
- How long is the risk period?
- Set in the documents. Purple Re's Series 2023-1 risk period runs to April 17, 2026 unless terminated earlier; Jamaica's 2024 World Bank bond covers 3.67 years and Mexico's 2024 classes four years.
