Ascot reorganizes into two divisions and hires AIG's Chris Flatt to run consumer lines

Ascot Group reorganized into two divisions effective October 1 and named three executives to lead them, all reporting to group chief executive and president Jonathan Zaffino, making it the most structural move in a week of specialty-carrier appointments that otherwise landed at the segment level. Mark "Sarge" Pepper, who joined Ascot at its 2001 founding to run treaty reinsurance and has been group chief underwriting officer since 2009, becomes president of global underwriting, working with Zaffino on growth strategy, product development and underwriting talent across the UK, US and Bermuda operations. Elizabeth Johnson, at Ascot since 2020 and group chief operating officer since 2024, takes the presidency of specialty insurance and reinsurance, a new division combining Global Specialty, Bermuda Specialty/Leadline Capital Partners and US Specialty under one leader; she previously spent nearly two decades at AIG, including as global head of excess casualty. Chris Flatt joins in early November as president of a newly formed consumer solutions division that will include high-net-worth personal lines, having most recently been AIG's global chief underwriting officer.

Flatt's division changes what Ascot sells, adding capacity in a segment where brokers have struggled to place high-value homes in catastrophe-exposed areas, while putting the specialty units under Johnson gives wholesale and retail partners one appetite to read across Ascot's platforms. Bermuda's record capital is the backdrop: as this publication argued in August, the island's capital has grown more than three times faster than premiums, leaving its largest balance sheets with room to give back terms in the lines they already write. A consumer arm is one place to put capacity without conceding rate to a rival, though no figure has been given for how much Ascot intends to commit, which makes the consumer division's first full year the thing to watch.

Everest Group appointed Nandini Mani as senior vice president and group chief claims officer with immediate effect, succeeding Andrew McBride, who is retiring; she was previously Everest's chief compliance officer and, before that, ran Chubb's overseas general claims organization of more than 2,000 staff. Claims leadership shapes how coverage disputes and large losses are resolved, so the practical question for brokers holding complex placements on Everest paper is whether anything about how disputes get resolved changes with her.

MSIG USA hired Oscar Aguilar as head of excess and surplus property, joining from Liberty Mutual where he was senior vice president and national manager of major accounts property, shared and layered, and with earlier roles at Ironshore and Brit Insurance. Chief executive Peter McKenna said Aguilar's retail and wholesale relationships would help MSIG USA build an E&S property offering brokers could rely on.

The week's specialty appointments share a shape: two of the three came from larger rivals—AIG's global chief underwriting officer and a Liberty Mutual senior vice president—and each landed at the segment level, in claims, E&S property, and consumer lines. Ascot's restructure goes furthest, building a division around a personal-lines market described as hard to place, and all three of its new leaders are in their seats before January renewals, the first date on which the consumer division's appetite is measurable in submissions.
