Lyndon Southern Insurance Company, part of the Tiptree-owned Fortegra group, has filed for a rate and rule update to its Inland Marine program in Idaho. The filing, generated on November 18, 2025, is set to take effect upon regulatory approval for both new and renewal business.

The filing requests an overall 6.2% rate increase, even though the current program shows $0 in written premium and no affected policyholders—a notable discrepancy and the clearest red flag in the submission. Still, the broader Fortegra platform reported $995.3 million in net written premiums in 2024, indicating this program represents a dormant or unused segment rather than a core line.

For new business or new ownership lasting under six months, the insurer is adding a requirement that premiums be calculated on a provisional basis and rerated at the six-month mark.
