Italian professional liability is almost universally claims-made. It seems a technical detail reserved for actuaries, but in reality it determines the structure of the entire underwriting workflow: how to calculate the premium for a decade-long retroactive, how to handle mandatory run-off for doctors, how to reserve IBNR on a portfolio where claims emerge years after the fact. A PAS that mismodels these extensions creates two types of problems: cover gaps (claim emerges but falls neither under old nor new policy) or undue cover (insurer pays for a claim that should be excluded). Both become disputes.
The two triggers: claims-made and loss-occurring
The cover trigger is the rule determining which policy pays a given claim:
- Loss-occurring: the policy in force at the triggering-event date pays. If the medical error is 15 March 2023, regardless of when the claim arrives, the policy in force on 15 March 2023 pays.
- Claims-made: the policy in force at the claim-reporting date pays. If the medical error is 15 March 2023 but the claim arrives on 10 September 2026, the policy in force on 10 September 2026 pays — provided it has retroactive covering 2023.
Loss-occurring is simple to model but discourages insurer switching (you leave an open "tail" every year). Claims-made is more flexible for switching (with retroactive) but more complex to model correctly.
Italian insurers pushed for spreading claims-made for professional liability mainly for two reasons: (1) exposure control: at period-end future exposure is limited by the in-force portfolio + run-off extensions, doesn't depend on facts occurred decades earlier; (2) Solvency II compatibility: capital requirements are clearer, IBNR reserves calculated on shorter reporting patterns.
The retroactive: how to model it without gaps
The retroactive (retroactive date) is the date from which the policy covers triggering events, even if prior to the policy term. Example: claims-made policy term 01/01/2026 - 31/12/2026, retroactive 01/01/2016: covers claims reported in 2026 for events occurred from 01/01/2016 onwards.
The retroactive can be:
- N-year limited: 5, 10, 15 years from inception.
- Specific date: the professional's first PI cover date (continuity).
- Unlimited: covers any prior triggering event, significantly higher premium.
A PAS models the retroactive as absolute date on the policy, not relative duration. Modelling it as "5 years" is an error: if renewal comes in February of the following year, a "rolling" retroactive would create a one-month gap between old and new policy. Correct modelling:
- Policy A (2024-2025): retroactive 01/01/2014.
- Policy B (renewal 2025-2026): retroactive 01/01/2014 (same!).
- Policy C (renewal 2026-2027): retroactive 01/01/2014.
The retroactive date travels with the professional, doesn't shift at every renewal. This is "retroactive continuity" the PAS must guarantee automatically on renewals.
Premium calculation for retroactive
IVASS-approved tariffs provide multiplicative factors on the base premium depending on retroactive depth. Simplified example:
- No-retro policy: base 100%.
- 5-year retroactive: 130-150%.
- 10-year retroactive: 170-210%.
- Unlimited retroactive: 250-350%.
Factors vary by category: surgeons have higher factors than GPs, gynaecologists higher than other specialists, etc. The PAS implements a matrix category × retro depth × geographic area → multiplicative factor.
The run-off: the extension that saves or sinks
The run-off (extended reporting period) extends claims-made cover beyond the end of the insurance relationship, allowing handling of claims for events during the policy term but reported after. Typically triggered in 3 scenarios:
- Retirement: the doctor stops practising, but claims can emerge up to 10 years later (long limitation period for healthcare liability).
- Death: the run-off protects the professional's heirs from claims against the estate.
- Removal from the roll: disciplinary or voluntary cancellation.
L. 24/2017 (Gelli-Bianco) makes 10-year run-off mandatory for healthcare practitioners. For other categories (lawyers, engineers, accountants) run-off is optional but in practice strongly recommended.
Run-off modelling in PAS
The run-off is a standalone policy with specific features:
- Lump-sum premium collected at activation (at activity cessation), calculated as 1.5-3× the ordinary annual premium to cover 10 years.
- Non-cancellable by the insurer: once activated, cannot be terminated until natural expiry.
- Claims developed over 10 years: claims can emerge any time in the 10 years, with decreasing pattern (most within 3-5 years of cessation).
- Retroactive continuing the ordinary policy's: if the doctor had retroactive from 01/01/2014, the run-off keeps the same date.
A concrete example: surgeon
Carlo Rossi, orthopaedic surgeon, practising since 2008. First PI policy in 2008 (insurer X). Switches to insurer Y in 2015 (retroactive recognised from 2008). Retires 31/12/2026.
What insurer Y's PAS must have to correctly handle Carlo Rossi:
- Ordinary policy 2015-2026: claims-made, retroactive 01/01/2008, annually recalculated premium with increasing retroactive factor (as retro "grows").
- Run-off 01/01/2027 - 31/12/2036: activated at retirement, covers claims reported in the 10 post-retirement years for events from 2008 onwards (during ordinary cover).
- Claims to handle: for the 10 run-off years, the insurer must maintain IBNR reserves on residual exposures, handle any emerging claims, calculate regress/recovery where applicable.
A claim emerging on 15 June 2030 (during run-off) for an event on 12 March 2018 (during ordinary) is covered: the event is in retroactive, the report is in run-off. A PAS that mismodels does not recognise it and a cover gap arises — challengeable by the claimant.
IBNR on claims-made: why it needs different logic
IBNR (Incurred But Not Reported) on claims-made has different logic than traditional loss-occurring. On loss-occurring, at period-end the policy closes, but claims keep emerging for years: IBNR is projection of how many will emerge, based on historical patterns.
On claims-made, the claim MUST arrive during the policy term (or run-off). So IBNR focuses on:
- Reported but not yet assessed claims (internal reserve).
- Claims in evolution (open cases, ongoing appraisals): IBNER (Incurred But Not Enough Reserved).
- Events occurred, damaged party aware, but not yet formalised (much narrower window than loss-occurring).
The analytics module implements actuarial methods (chain-ladder, Bornhuetter-Ferguson) on development triangles, distinguishing claims-made vs loss-occurring patterns. For Italian PI portfolios, pattern stabilisation is typically obtained after 5-7 observation years.
Three frequent errors in generalist PAS
- Retroactive as "relative duration". Modelling retroactive as "5 years from inception" rather than absolute date. Effect: at every renewal it shifts by 1 year, creating potential cover gaps for events earlier in time.
- Run-off not non-cancellable. Leaving the run-off subject to the same cancellation conditions as the ordinary policy. Effect: in case of insurer financial issues, you risk not honouring the cover. The run-off must be technically "locked" in the system.
- IBNR calculated as loss-occurring. Applying loss-occurring development patterns (10-15 year long) to a claims-made portfolio. Effect: over-reserved, distorted Solvency II capital requirement, underestimated technical profitability.
In summary
Claims-made, retroactive and run-off are three technical pieces of an integrated puzzle. Modelling them correctly in the PAS means ensuring covers compose without gaps and without undue overlaps, premiums reflect actual risk, reserves are calibrated to real line patterns. For a coverholder, MGA or insurer operating on Italian professional liability, it is the single aspect you cannot cut on.
Frequently asked questions
Can I convert a loss-occurring policy to claims-made mid-term?
It is not a clean operational conversion: in practice you close the loss-occurring policy (which keeps covering events occurring during its term, even if reported later) and open a new claims-made policy with possibly aligned retroactive. The PAS must handle the two policies as coexisting: loss-occurring stays 'open in tail' for late reports of in-period events, claims-made starts new. Overlapping the two models on the same policy creates disputes.
How is the premium calculated for retroactive extension beyond 5 years?
IVASS-approved tariffs provide multiplicative factors for retroactive: typically +20-40% premium for 5-year retro vs no-retro policy, +50-80% for 10 years, +100-150% for unlimited. For high-risk categories (surgeons, gynaecologists) factors are higher. The PAS implements these factors as parametric multipliers on the base tariff, with dependence on the principal's professional category.
Does the mandatory 10-year run-off (L. 24/2017) apply retroactively?
The 10-year run-off obligation operates for policies issued after the law's entry into force (8 March 2017 for the law, but minimum-policy-requirements provisions were fully implemented with 2020 implementing decrees). Earlier policies have run-off per their original contract conditions. For doctors buying a new policy today, 10-year run-off is non-negotiable.
How much IBNR to reserve on a claims-made professional liability portfolio?
Heavily depends on category, portfolio age, development patterns. For healthcare PI on a mature portfolio (5+ years of experience), a typical range is 40-70% of earned premium, with loss development pattern stabilising after 5-7 years. For lawyer PI, the range is lower (15-30%) for faster development. For new categories or young portfolios, market benchmark + prudent buffer is needed. Formal IBNR calculation requires actuarial methods (chain-ladder, Bornhuetter-Ferguson) applied to development triangles: the Analytics module of an evolved PAS implements them.
How is a claim emerging after activity cessation but before run-off expiry handled?
Identical to a claim on an active policy, with two distinctions: (1) the guaranteed principal is in 'ceased activity' status — post-payment regress is towards the professional (retired) or heirs (if deceased), with different timing and process; (2) the run-off is typically lump-sum premium already collected, so cover solvency is technically guaranteed by reserves built at issuance. Standard settlement workflow, but with greater attention to documentation (the profession has ceased, evidence on original activity may be dispersed).
For a lawyer changing insurer, how is the retroactive handled?
The tool is recognition by the new insurer of the previous policy's retroactive. The lawyer declares the first PI cover date (e.g. 2015), the new insurer issues a claims-made policy with retroactive starting from the same 2015 date. Premium calculated with standard retroactive factor. Important: must also declare any known facts or pending claims, which must be explicitly excluded from the new policy (the new insurer doesn't inherit handling of already-open claims).
