Cincinnati Financial has experienced strong growth in its Commercial Lines Insurance segment, fueled by a combination of high-single-digit rate increases, steady new business growth, and the strategic integration of predictive analytics tools for underwriting, pricing and claims.
The Commercial Lines Insurance segment offers coverage for commercial casualty and property, commercial auto and workers' compensation. This segment also provides contract and commercial surety bonds, fidelity bonds, management liability, and machinery and equipment insurance products. The segment benefits from an increase in agency renewal written premiums that include higher average pricing and a higher level of insured exposures.
This segment continues to use predictive analytics tools to improve pricing precision and segmentation while leveraging the local relationships with agents. It intends to grow through additional agency appointments, enhancing underwriting expertise, and cross-selling or product expansion that meets the needs of an even larger percentage of agencies' total commercial portfolio. New agency appointments significantly boost the new business premium volume of the commercial lines.
