Every answer and its explanation appears here once you have finished the path. Each one then links to the matching glossary entry, where the concept is set out in full with its worked example.
1. A carmaker promises a 65,000 euro vehicle to anyone scoring a hole in one at a promotional day. The insurer charges a 12,000 euro premium. Two players hole out. What is the insurer's technical result on the deal?
A loss of 118,000 euros
Prize indemnity transfers to the insurer the risk that a promotional prize is actually won. The insurer estimates the statistical probability of the win, prices accordingly, then pays the promised sum to the organizer, who hands the prize to the winner. Here two prizes of 65,000 euros make a 130,000 euro cost against 12,000 euros of premium, a loss of 118,000. The arithmetic is instructive because it shows where this line's risk really sits: the premium was built on a probability estimated at sixteen percent for a single win, with two thousand participants of whom roughly three hundred and twenty played to a sufficient standard. The loss does not come from mispricing the chance of a hole in one, it comes from the extreme sensitivity of the outcome to the number of wins: zero, one or two produce three results with nothing in common. This is a very low frequency line with a fixed severity, where the law of large numbers only works across a portfolio of events, never within a single one.
Glossary entry →2. In kidnap and ransom cover, the insurer never deals with a kidnapper and works by reimbursing the insured, never by paying directly. What does that mechanism protect?
The insurer's position under crime financing and sanctions regimes
Kidnap and ransom is the only line where the contract directly alters the risk it covers: disclosing its existence raises the danger and can void the policy, so many protected people do not know they are covered. The reimbursement mechanism follows the same caution but serves a different end: by never paying the kidnapper and confining itself to reimbursing the insured, the insurer stays clear of the regimes that punish the financing of crime and those that forbid transferring funds to a designated person. What the client buys first is immediate access to a team of negotiators, security consultants and lawyers; the reimbursement comes after. Their first task is to establish proof of life, through a question only the abducted person can answer, because a share of demands come from opportunists holding nobody. The line is concentrated in a single marketplace that pools its claims data, which lets it govern a price rather than merely carry a risk.
Glossary entry →3. A world tour insured for 120 million euros of receipts over sixty dates is canceled two weeks before it opens, the artist being hospitalized for heart surgery. Which cover responds?
Non-appearance
Event cancellation insurance protects organizers against financial loss from a cancellation or postponement caused by an unforeseeable external event, and it splits into distinct covers worth naming correctly. Abandonment and cancellation addresses net receipts lost when the event does not take place, adverse weather covers extreme conditions, and non-appearance covers the failure of a headline artist or athlete through illness or death. The last one responds here, since the trigger is the unavailability of the person the whole event is built around. The indemnity is on net receipts, that is, less the variable costs the cancellation saves, which stops the organizer profiting. Covid-19 was this line's systemic loss, with billions of dollars claimed simultaneously around the world: a textbook accumulation on a cover everyone assumed was made of independent events.
Glossary entry →4. An ordinary fire goes out by removing fuel, oxygen or heat. Why does a battery storage loss not follow that logic?
Because one cell's failure triggers its neighbors, and residual energy stays available for days
Thermal runaway does not obey the fire triangle: cooling slows it without stopping it, starving it of air is not enough. The core of the problem is propagation, one cell's initial failure releasing heat that triggers the adjacent cells, which reaches the module, then the unit, then potentially the whole installation. That produces a feature with no equal among industrial risks: a storage loss is not over when it looks extinguished, since the residual energy of cells not yet in runaway stays available for days. The consequence for an insurer reads straight off the business interruption indemnity, whose duration runs not from apparent extinction but from the moment the site can be declared safe. And the conceptual shift goes deeper still: the peril comes from the thing itself rather than from an outside event striking it, the energy it holds being at once what gives it value and what destroys it.
Glossary entry →5. An archive piece is lent to a traveling exhibition. Why does the lender's ordinary policy leave a gap in cover, and where does it fall?
It ceases to operate once the item leaves the named location, so during transit and handling
Nail to nail cover protects a valuable object from the moment it leaves its usual place until it returns, taking in packing, crating, road, air or sea transit, intermediate storage including in customs zones, and the journey back. It exists because an ordinary policy stops operating as soon as the item leaves the named location, opening a gap precisely where risk peaks: most losses happen during handling, not during static display. The weak point of this kind of cover lies less in the length of the journey than in the seam, the moment custody passes from one hand to another, between lender, carrier and host institution. Each party insures its own leg, and the gaps between their terms are closed by a difference in conditions policy, which the lender buys so that the join is not the only uncovered point of the trip.
Glossary entry →6. A buyer discovers, after closing, a tax liability the seller had not disclosed. What does a representations and warranties policy taken out at the time of the deal change?
It indemnifies the buyer, instead of sending them to litigation against the seller
Representations and warranties insurance, known as RWI or W&I, covers loss arising from the inaccuracy of the representations and warranties a seller gives in a merger or acquisition. It transfers to an insurer the risk that a warranty proves false after closing, whether a hidden dispute, an undisclosed tax liability or a compliance failure. Its most important effect lies less in the indemnity itself than in what it makes possible in the negotiation: by reducing the need for escrow, it allows the seller a clean exit, which has made it a standard instrument in private equity, where returning sale proceeds to a fund's investors does not sit well with sums locked up for years. It belongs to transactional risk underwriting, a distinct craft that requires reading the sale agreement and the underlying due diligence with a lawyer's eye: what the insurer prices is the quality of verification work already done by others, far more than the asset.
Glossary entry →7. A company is insolvent and its creditors are suing its directors. The company can no longer indemnify them. Which part of the directors and officers policy responds?
Side A, which covers the directors directly
A directors and officers policy is structured by the nature of the insured being protected, and knowing the three parts tells you which one will matter on the day it counts. Side B reimburses the company when it indemnifies its directors, which is the ordinary case. Side C, the entity cover, protects the company itself for its own liability, usually securities litigation. Side A covers the directors directly where the company cannot indemnify them, whether because it is insolvent or because the law forbids it. That is the case here, and it is why Side A is the most valuable protection for a personally exposed director: the other two parts assume a company able to pay, which is exactly what is missing in the situations where a director is most exposed. For that reason dedicated Side A policies exist, bought above the ordinary program.
Glossary entry →8. The Deepwater Horizon disaster of 2010 showed the scale of a peril specific to exploration and production. What does well control cover pay for?
Regaining control of the well, firefighting, pollution cleanup and redrilling
Well control insurance covers the costs of regaining control of an oil or gas well that has gone out of control, a situation known as a blowout, together with firefighting, pollution cleanup and redrilling. The distinction from the rest of an operator's program is what matters: damage to the platform sits with property cover, lost production with business interruption, third party and environmental exposure with liability covers, and well control pays for what fits none of the three, namely the operation of shutting the well itself. Deepwater Horizon in 2010 showed how large such an event can be, combining loss of life, a large scale oil spill and enormous liabilities, each falling under a different cover. Underwriting demands sharp technical knowledge of drilling operations and of the operator's quality, because the probability of a blowout depends less on geology than on the procedures actually followed.
Glossary entry →9. After an oil spill caused by a ship, who pays for the cleanup and the third party claims, and on what principle?
The owner's P&I club, a shipowners' mutual that pools very large losses
Protection and indemnity clubs are shipowners' mutuals covering the liabilities arising from operating vessels: injury to crew and passengers, marine pollution, damage to port installations, liability for cargo carried, wreck removal costs. These liabilities are distinct from damage to the ship itself, which belongs to hull cover, and confusing the two is the commonest error in marine insurance. The mutual structure is not a historical relic, it answers a precise problem: these liabilities can reach amounts no single insurer would carry, above all in an oil spill. Member owners therefore reinsure each other, then within an international group that pools the very largest losses above a threshold, which allows limits with no equivalent on the ordinary market. Cover is thus obtained by pooling rather than by transfer, and the member is at once insured and a carrier of everyone else's risk.
Glossary entry →10. A company can no longer repatriate profits from a country that has just frozen transfers. How does this political risk cover differ from a currency hedge?
It addresses the administrative blocking of flows, not movements in the rate
Currency inconvertibility and non-transfer cover the inability of an investor or company to convert local currency into hard currency or to repatriate funds out of the host country, because of state-imposed restrictions: exchange controls, frozen transfers, a shortage of foreign currency. The distinction from ordinary currency risk is sharp and worth holding: currency risk is about the price at which a conversion happens, this is about whether it can happen at all. A currency hedge is useless when the transaction is prohibited, since it fixes a rate for a trade that will not take place. This cover belongs to the political risk family alongside expropriation and political violence, and is bought by international investors, project finance banks and export credit agencies. Underwriting it means assessing a country's external solidity, its level of reserves and its history of control measures, which is sovereign analysis far more than corporate analysis.
