2023 compared to 2022

Total ceded written premiums for 2023 was $962.7 million, a decrease of $99.4 million from 2022. Retention ratio increased from 58.0% in 2022 to 60.7% in 2023 as a result of a change in business mix and the decision to restructure a portion of our outwards reinsurance renewals.
