Carrier appetite summary
Berkley Corporation operates through multiple subsidiary brands. Underwriting guidance is mostly published at the operating-company level rather than a single WRB corporate page. Key current themes: 1) Workers Compensation – Berkley Industrial Comp (industrial segment) - Preferred business: middle‐market and larger industrial employers with strong safety culture in four core segments: commercial construction (primary focus, limited residential), 4‑wall manufacturing that supports construction and mining, industrial services (heavy equipment hauling, equipment installation/repair, plant maintenance, crane & rigging), and mineral/metallic mining other than coal. ([berkleyindustrial.com](https://www.berkleyindustrial.com/appetite/?utm_source=openai)) - Geographic scope: national workers compensation footprint; availability can vary by jurisdiction but site markets "consistent, reliable coverage nationwide" for these industrial classes. ([berkleyindustrial.com](https://www.berkleyindustrial.com/appetite/?utm_source=openai)) - Submission requirements: ACORD 125, ACORD 130 including narrative of operations, Berkley Industrial Comp supplemental application, current and prior year experience mod worksheets, five years of currently valued loss runs, and a current drivers list for haulers or accounts with significant powered-haulage/auto fleet exposures. Submissions are sent to the Berkley Industrial Comp submissions email; no explicit advance-days requirement for new business, and they advertise fast turnaround. ([berkleyindustrial.com](https://www.berkleyindustrial.com/appetite/?utm_source=openai)) - Underwriting notes: appetite is specifically industrial; risks outside construction/manufacturing/industrial services/mineral & metallic mining will generally fall outside their preferred "box." They emphasize disciplined underwriting and will expect clean, well-documented loss and exposure data to maintain a "high hit ratio." ([berkleyindustrial.com](https://www.berkleyindustrial.com/appetite/?utm_source=openai)) 2) Program Business / Commercial Package, Property & Casualty, Umbrella (Berkley Program Specialists) - Distribution model: writes via selected program administrators with delegated underwriting authority; they target casualty-driven commercial programs, not individual open-broker submissions. Producers must be aligned to, or acting as, a program administrator partner rather than submitting one-off risks. ([berkley-ps.com](https://www.berkley-ps.com/program-appetite/?utm_source=openai)) - Preferred programs: commercial-lines focused books with minimum ~$7M GWP, strong market presence, good documented premium and loss history, clear sustainable underwriting niche, and robust rating/issuing/servicing infrastructure. Appetite increases when administrators provide deep expertise and rich performance data. ([berkley-ps.com](https://www.berkley-ps.com/program-appetite/?utm_source=openai)) - Lines: site highlights separate "Professional Lines" and "Property & Casualty" risk appetite segments for programs, which can encompass commercial property, general liability, and umbrella/excess depending on each approved program. Individual class-level guidelines reside in program-specific documents, so underwriters should consult the applicable program guide before quoting. ([berkley-ps.com](https://www.berkley-ps.com/program-appetite/?utm_source=openai)) - Submission expectations: prospective programs must present premium and loss histories, business plan, target classes, rate/underwriting rules and operational capabilities. Day‑to‑day risk submissions flow through each program administrator per its manual; direct open-market submissions to Berkley Program Specialists are generally outside appetite unless tied to an approved program. ([berkley-ps.com](https://www.berkley-ps.com/program-appetite/?utm_source=openai)) 3) Captives and Alternative Risk – Berkley Risk - Products: workers compensation, general liability and automobile liability for group captives, pools and alternative risk structures. They describe themselves as a full-service insurer providing underwriting, risk control, accounting, reinsurance placement and claims. ([berkleyriskcaptives.com](https://berkleyriskcaptives.com/faq/?utm_source=openai)) - Underwriting approach: Berkley Risk prefers to keep underwriting in‑house rather than granting broad underwriting authority, working with captive partners to define the underwriting "box" for each deal. That box establishes acceptable classes, limits and attachment structure specific to each captive. ([berkleyriskcaptives.com](https://berkleyriskcaptives.com/faq/?utm_source=openai)) - Appetite: actively looking to add volume in WC, GL and Auto liability. Individual risk and security terms vary by partner financial strength, risk severity and claims development pattern; security often set between 1.25–1.50 times ultimate expected annual loss. ([berkleyriskcaptives.com](https://berkleyriskcaptives.com/faq/?utm_source=openai)) - Broker notes: brokers should be prepared to place business into a captive or alternative risk structure rather than a standard guaranteed-cost policy, and to provide detailed loss information, membership profile and security structure for each opportunity. ([berkleyriskcaptives.com](https://berkleyriskcaptives.com/faq/?utm_source=openai)) 4) Recreational Marine / Boat & Watercraft – Berkley One - Product: personal recreational marine coverage for private-pleasure boats and yachts, including hull, engines and fixtures, with options for agreed value. Coverage extends to theft, collision, fire, storm damage and related perils, plus medical payments for insureds and guests. ([berkleyone.com](https://www.berkleyone.com/offerings/watercraft_insurance/?utm_source=openai)) - Target risks: individually owned recreational vessels used for personal pleasure; the marketing focus is on higher-value craft where agreed value and enhanced coverages are relevant. They offer coverage for non-owned vessels when insured occasionally operates another person’s boat, newly acquired watercraft (automatic short-term coverage, currently 15 days), named-storm haul-out, bottom inspection after striking submerged objects, towing and emergency assistance, and environmental clean‑up for fuel/oil leakage following a covered loss. ([berkleyone.com](https://www.berkleyone.com/offerings/watercraft_insurance/?utm_source=openai)) - Preferred business indicators: clean loss history, completion of formal boater education, and use of modern safety equipment, all of which may qualify for premium savings. Underwriters will expect clear operator experience and safety profile; risks without these characteristics are less competitive or may be declined. ([berkleyone.com](https://www.berkleyone.com/offerings/watercraft_insurance/?utm_source=openai)) - Likely restricted/declined risks (inferred): the site markets recreational personal use; commercial use, charter, or live‑aboard exposures and very high-performance vessels are not described and are typically handled by other marine units or declined, so producers should pre‑screen for non‑pleasure or high‑hazard marine exposures before submitting. 5) General producer / broker notes across Berkley entities - Structure: W. R. Berkley functions as a holding company for numerous specialized underwriting companies. Each brand (e.g., Berkley Industrial Comp, Berkley Program Specialists, Berkley One, Berkley Offshore, Berkley Fire & Marine) publishes its own appetite and submission rules. Producers must match the risk to the correct operating company and use that entity’s forms and portals. - Underwriting discipline: corporate materials emphasize strong risk‑appetite management and capital-at-risk limits, with each business setting a clear underwriting box aligned to its specialty. Underwriters typically require complete, high‑quality submissions (applications, narratives, loss runs and supporting data) and are selective about classes that fall outside core niches. ([responsibilityreports.com](https://www.responsibilityreports.com/HostedData/ResponsibilityReportArchive/w/NYSE_WRB_2023.pdf?utm_source=openai)) Operationally, for Workers Comp, Commercial Package/Umbrella/Property and Boat/Watercraft with Berkley, brokers should: - Route industrial WC to Berkley Industrial Comp using its ACORD/supplemental/loss‑run package and email submission workflow. - Place commercial package, property and umbrella business through an approved Berkley program administrator where a relevant program exists, using the program’s rules rather than open-marketing directly to Berkley Program Specialists. - Submit personal boat/watercraft under Berkley One’s recreational marine offering, ensuring the risk is strictly personal-pleasure use with adequate operator experience and safety features, and be prepared to document vessel value and any prior losses. - For captives or alternative WC/GL/Auto structures, coordinate with Berkley Risk, recognizing that deals are bespoke and require detailed loss and financial information and acceptance of captive participation/security terms.
