Lloyd’s global specialist re/insurer MS Amlin has launched a new sub-syndicate, s1673, to target growth opportunities and provide greater flexibility and capacity for brokers.

ms-amlin-logo-2Named after the year the Mitsui enterprise was founded in Tokyo, MS Amlin explained that s1673 is “inextricably linked” to its Lloyd’s Syndicate 2001, supported by the same capital. From a Lloyd’s perspective, all risks written through s1673 will consolidate under its Syndicate 2001.

s1673 will reportedly support the growth of business written through MS Amlin’s recently formed Portfolio Solutions team, established to capture underwriting opportunities arising from the insurer’s MS&AD global network, as well as from fast-follow relationships and business written under Lloyd’s innovation and transition codes.

The firm added that the sub-syndicate will also allow it to increase its share and relevance to brokers in existing lines written on MS Amlin’s Syndicate 2001, by writing additional lines.

“This ability to take a greater share of risks can be deployed across all classes of business at the discretion of MS Amlin underwriters, giving brokers access to greater capacity to support clients, where risks are aligned with MS Amlin’s underwriting appetite,” MS Amlin said.

Martin Burke, MS Amlin’s Chief Underwriting Officer, commented, “This launch reflects our commitment to trade creatively and explore new commercial routes to sustainable, profitable growth in an evolving market.

“s1673 will help us expand our Portfolio Solutions division, which includes leveraging our parent group’s international network to access new underwriting opportunities and extend our specialty solutions to new clients globally.

“The sub-syndicate will also serve as a home for enhanced capacity opportunities, enabling underwriters to selectively deploy more capacity to high-quality risks written by MS Amlin’s Syndicate 2001.

“For our brokers, this provides greater flexibility and capacity to trade more easily and allows us to support our mutual clients more effectively.

“s1673 allows us to pursue new opportunities, measure their performance clearly, and support brokers more decisively on strongly performing lines.”
