The questions behind a storm-exposed balance sheet

I treat each state, and increasingly each group of counties, as a separate decision rather than a line in a combined ratio. The evidence includes five-year loss experience adjusted for storm frequency, the share of roofs older than fifteen years, the deductible mix, the modelled contribution to our one-in-100 convective-storm loss and the rate that the state's review process is likely to allow. I also map agency concentration, because an exit can end a relationship that writes our farm business elsewhere. The options are rarely binary. A county can be retained with a roof-age payment schedule, a percentage wind and hail deductible or a pause on new business. Withdrawal comes last, and when we use it I want the notice period, the agents' replacement work and the regulator's questions planned before the first letter is sent.

Our catastrophe programme protects a surplus that a mutual cannot replenish by issuing equity. I model it with the finance team, who place and sign it through our intermediary. My part is to show the board what each structure buys: the retention we can absorb in a bad year without breaching our internal capital floor, the limit needed at the top, and whether aggregate or frequency covers are worth their price. Since 2023 reinsurers have pushed retentions upward and aggregate protection has become scarce. I compare each layer's expected recovery with its cost and with the volatility it removes, then describe the residual risk plainly. A cheaper programme is no saving if it moves unpriced risk onto members' surplus, and an expensive one is not prudence if the money would do more as rate and underwriting action.

A rate change passes through several stages before it improves results: the actuarial indication, the filing, the state's review, the effective date, the renewal of each policy and the earning of premium across the term. Some of our states require approval before a rate is used; others allow use after filing, subject to later review. I build the plan around those timelines rather than around the indicated figure. Our actuaries own the indications and the filings. I work with them on sequencing, for example whether a deductible change or a roof-age schedule will reduce loss costs sooner than a rate increase. I also keep the agents' view in the plan, because a large increase announced without explanation sends the better risks to competitors first and leaves us with the policies we would least choose to keep.

Every Ostervale policy arrives through an independent agency, and most of those agencies also represent several competitors. Our standing with them rests on underwriting consistency, claims service after a storm and a fair commission. In 2022 I led a review of all 1,280 appointments with our head of agency relations. We kept 1,050, judged on three-year loss ratio, retention, farm-line specialism and service record rather than premium volume alone. We also redesigned contingent commission to reward three-year profitability and retention instead of a single year's growth. Some long-standing small-town agencies lost their appointments, and two regional managers argued hard against that outcome. I understand their view. The evidence supported the review, but I now weigh an agency's place in its community explicitly before any appointment is ended.

A mutual's capital routes are few and each one changes something for its members. It can retain earnings, buy reinsurance, issue surplus notes, affiliate with another mutual or, where state law permits, reorganise into a mutual holding company that can later own a stock insurer. Surplus notes add a fixed cost and need regulatory approval before payments are made. An affiliation can bring scale while moving important decisions to another board. A holding company reorganisation opens a path to outside equity, but it requires regulatory approval and member engagement and alters the long-term relationship between members and the company. I prepare these options for the board with outside legal and actuarial advisers. My role is to keep the comparison honest: which problem the capital solves, for how long and who carries the cost.
