The real cycle is plan, run, reconcile, explain and submit, repeated under deadline. The modelling is rarely what slows it down. The weeks disappear into versions, hand-offs and rebuilding the story of how a number came to be.
Underwriting sends plan assumptions, then revisions, then “one more scenario”. Each request queues behind the next model run, and each answer lands in another spreadsheet. With STEER, every assumption is versioned with an owner. Indicative answers keep the discussion moving, and governed runs confirm what actually goes into the plan.
Run records, reconciliations, review notes and approvals are captured as the work happens. The evidence behind an SCR submission (or, for a Lloyd’s syndicate, the capital return) is assembled as you go, not reconstructed in the final fortnight.
“Why is this run different from last quarter’s?” Every run records exactly what changed: inputs, assumptions and model version. Compare any two identified runs by class, risk type and risk driver, and see where the capital moved without rebuilding the analysis by hand.
The movement analysis lives next to the figure it explains. When Cyber growth adds less capital than expected, the explanation (extra stop-loss recoveries, a shift in diversification) is attached to the result, ready for the committee.
STEER works around your approved Internal Model rather than replacing it. Every run, comparison and sign-off is kept, so the pack Lloyd's expects is built during the work, not after it.
Requirements summarised from Lloyd's Model Change Guidance (February 2024, June 2025) and Capital Guidance (April 2025).
The model doesn’t change. What changes is how much of the cycle goes on analysis rather than administration. These are the measures STEER is built to move.
The time from plan assumptions received to a signed-off capital result.
The number of plan alternatives evaluated per cycle, indicative and governed.
Validation and audit points raised on evidence, documentation or traceability.
The CUO office turns capital into underwriting decisions: how much to write, where and at what price. That only works when underwriting and capital are reading the same numbers, from the same run, at the same time.
Capital is only useful once it becomes limits the business can act on: premium caps, aggregate limits and line sizes. STEER ties each limit to the capital view behind it, so a change in appetite and a change in capital can be traced to each other.
Which lines earn their capital? STEER shows return on allocated capital alongside marginal capital, the extra capital the next pound of premium would need. Because of diversification, a line can look expensive on its own and efficient within the portfolio, or the reverse. STEER shows both views side by side, from the same governed run.
When the book drifts from plan through rate movements, mix shifts or a large loss, test the response straight away with an indicative view. Then confirm it with a governed run before committing to it.
One story, consistent with the capital team’s numbers, because both teams read the same record. The board sees one version of the plan, not two competing decks.
When underwriting and capital read the same record, the conversation moves from “whose numbers are right?” to “which plan is best?”. These are the measures STEER is built to move.
The time from a business question being asked to a recorded, evidenced decision.
Limits exceeded before anyone saw them coming.
The gap between planned and actual mix, and the capital it consumes.
