A household policy covers one building at one address. The questions an underwriter asks about it are limited and change slowly: how it is built, what the local flood history looks like, what has been claimed before.

A multinational political violence policy can cover a business operating from hundreds of sites in dozens of countries. Each site sits in its own political and security environment. Some depend on the same ports, roads or power supplies. Conditions around them shift during the policy year, sometimes quickly. The questions are many, and the answers do not stay still.

That difference is why the research burden described in the first article of this series falls hardest on specialty insurance. The work of understanding the risk has to be done across many places at once, and done again as conditions change.

A site-by-site review is out of date before it is finished

Reviewing a large multinational account by hand means working through it in sequence: one region, then the next. Each location needs its incident history, the local political picture, the conditions at inception and anything that has changed since.

By the time the last region is done, the assessment of the first may be weeks old. If tension rises somewhere already reviewed, the team either proceeds with a picture it knows is dated or goes back and starts again. And when an event touches several countries at once in the middle of a review, the sequence breaks down entirely: the sites affected need answers now, wherever they sit in the queue.

Underwriters and analysts manage this through experience and long hours. The constraint is the method, which asks people to rebuild a picture that could already exist.

Five questions every renewal has to answer

Whatever the class, a specialty renewal comes down to the same five questions. Looking at each one shows where the time goes, and where infrastructure helps.

1. What did we assume at inception? The underwriter needs the picture of each location as it stood when the policy was written. Rebuilding that from archives and old files is slow. CORTEX keeps the history of each location, so the conditions at a given date can be set out directly, with their sources.

2. What has changed since? Where conditions have moved, the underwriter needs to know which way, how far and why. CORTEX can produce the same intelligence picture on a schedule and compare it with the last one, so attention goes to what has materially changed rather than to restating what has not.

3. Which insured locations does an event touch? When something happens, the first task is to relate it to the sites on cover. Where an insurer's locations are provided, CORTEX relates events and their surroundings to those places, including the infrastructure and routes nearby.

4. Where do our exposures concentrate? Accumulation is calculated in the insurer's own exposure systems and models, against its own limits and wordings. CORTEX does not price risk or model loss. What it supplies is the evidence about the places involved, so the people running those calculations know what has been happening around the sites they are adding up.

5. Where could one event touch several lines? A syndicate may write political violence, strikes, riots and civil commotion, kidnap and ransom, and cargo. A single event can reach several of them. Spotting where lines share locations or dependencies starts with knowing the places well, which is the evidence CORTEX holds.

In each case the judgement belongs to the underwriter. What changes is how much of the groundwork is already done when the question is asked.

The record matters as much as the answer

Specialty decisions are increasingly expected to be documented: what was known, when, from which sources, and why the decision followed. Underwriting committees, auditors and market oversight all ask versions of that question.

When the picture is assembled by hand, the record has to be assembled too, usually after the fact. When the evidence sits in a foundation that keeps sources and dates, the record of what was known at the time already exists. That matters well beyond renewal: after an event, at a claims review or in a dispute, the question "what did we know then?" has an answer.

Why specialty first

Other lines of insurance will face the same pressure in time. Specialty faces it first because the conditions come together there: risks spread across many locations, conditions that change during the year, scarce expertise that is stretched hardest during the events that matter most, and rising expectations for evidenced decisions.

The next article in this series looks at how risk intelligence has developed over the past two decades, and where analysts and advisers fit as it changes again.
