Insurance Curator Directors and Officers (D&O) insurance placement has become a strategic boardroom decision. For US-based organizations—especially those in high-litigation states like New York, California (San Francisco / Los Angeles), and Texas (Houston / Dallas)—deciding between multi‑carrier towers and a single‑carrier solution can materially affect capacity, pricing, claims handling, and renewal leverage. This guide, aimed at directors, officers, and in‑house counsel evaluating placements in the USA, explains the tradeoffs and provides tactical considerations for brokers and purchasing teams.
Executive summary
- Multi‑carrier towers assemble capacity from several insurers (often layering carriers by priority/attachment). They provide deeper capacity, spread carrier risk, and can improve market competition.
- Single‑carrier solutions consolidate risk with one insurer providing the full limit (or most of it). They simplify underwriting and claims handling and may produce pricing efficiencies for certain profiles.
- Choice depends on company size, risk profile, board makeup, litigation exposure, transaction activity, and broker relationships.
How multi‑carrier towers work (quick primer)
A typical multi‑carrier tower:
- Uses a lead/primary carrier for the primary $1M–$5M layer.
- Adds one or more excess carriers to build aggregate limits (e.g., $10M, $20M, $50M).
- Often involves different policy forms/wordings and reinsurance placements among carriers.
Benefits and downsides are summarized below.
Side‑by‑side: Pros and Cons
Pros of Multi‑Carrier Towers
- Capacity: Easier to assemble large limits (useful for public companies or M&A‑active firms).
- Market competition: Multiple carriers can mean better terms and pricing through competitive leverage.
- Risk diversity: Reduces single‑carrier concentration risk (carrier financial stress or large aggregate loss).
- Specialist access: You can include specialty players (e.g., Beazley for securities‑related expertise, Chubb for middle‑market stability).
Cons of Multi‑Carrier Towers
- Complex claims handling: Potential for coverage disputes between carriers on allocation and priority.
- Policy inconsistency: Varied policy forms and endorsement language can create gaps or ambiguity.
- Administrative burden: More paperwork, certificates, and coordination at renewal.
- Higher broker placement effort: Requires a broker with deep carrier relationships and negotiation experience.
Pros of Single‑Carrier Solutions
- Simplified claims process: One insurer to manage claims and indemnity decisions.
- Consistent policy language: Fewer gaps and easier interpretation.
- Possible pricing efficiencies: Large, reliable accounts may secure better single‑carrier pricing or sidecar arrangements.
- Stronger partner relationship: Single-carrier relationships can lead to underwriting credit and faster responses.
Cons of Single‑Carrier Solutions
- Capacity limits: Not all carriers can support very large limits alone.
- Concentration risk: Exposure to a carrier’s financial/claims volatility.
- Less market pressure: Fewer competitive anchors can limit price negotiation leverage.
Quick comparative table
| Feature | Multi‑Carrier Tower | Single‑Carrier Solution |
|---|---|---|
| Typical use case | Public companies, M&A, litigation‑prone sectors | Stable private firms, mid‑market insureds seeking simplicity |
| Capacity scalability | High | Limited by carrier appetite |
| Claims simplicity | Moderate to low | High |
| Policy consistency | Variable | High |
| Renewal negotiation leverage | High (if well-placed) | Moderate |
| Administrative complexity | Higher | Lower |
Pricing considerations and realistic ranges (USA market context)
Pricing varies widely based on company size, sector, financial condition, prior claims, and jurisdiction (NY/CA/TX often costlier). Below are approximate 2023–2024 US market ranges gathered from market reports and industry analysis:
- Small private company (revenues <$10M): $1,200–$8,000 per $1M primary D&O limit annually (often through specialty carriers or online MGA platforms).
- Middle‑market company (revenues $50M–$500M): $20,000–$150,000+ for layered programs (primary + excess towers) depending on limits and claims history.
- Public company (small cap to mid‑cap): $150,000–$1M+ for primary & first excess layers; total program costs often run into mid‑six to seven figures for larger caps.

Note: Individual carrier quotes vary. For example, Chubb, AIG, and Travelers are known to provide competitive primary and excess D&O programs to US middle‑market and large clients; specialty players such as Beazley and Liberty Mutual often participate in excess towers for higher‑risk slices. Brokers commonly combine these carriers to reach target limits and pricing.
Tactical guidance for Directors and Procurement Teams
- Assess the risk profile first: If your company faces high securities litigation exposure, regulatory scrutiny, or aggressive M&A, favor towers for capacity and specialist carriers.
- Prioritize clarity in policy language: Require harmonized wording and shared allocation protocols when using towers — this reduces post‑loss fights.
- Use broker competition strategically: Ask your broker to run competing tower and single‑carrier scenarios to test capacity and cost tradeoffs. (See Placement Strategies That Win Capacity: Techniques Brokers Use for Directors and Officers (D&O) Liability Insurance.)
- Demand carrier panel disclosure: Insist on a list of participating carriers, attachment points, and lead carrier responsibilities.
- Consider captive or retrospective solutions only after modeling long‑term cost and volatility.

When towers are practically mandatory
- Large public companies needing $50M+ limits.
- Firms in heavy litigation industries (biotech, fintech, energy).
- Organizations pursuing significant deal activity (PE portfolio companies, serial acquirers).
When a single carrier makes sense
- Lower complexity private companies prioritizing simplicity and fast claims service.
- Organizations that can negotiate exclusivity/volume discounts with a carrier/broker.
- When carrier credit and long‑term relationship value outweigh marginal premium savings.
Closing checklist for directors before sign‑off
- Confirm total program limits meet board tolerance for retention and uninsured exposure.
- Review carrier financial strength (AM Best ratings) and claims teams.
- Ensure broker provides a side‑by‑side quote with term sheets, attachments, and an explanation of allocation and contribution mechanics.
- Require a renewal strategy and timeline; see Timing Your Purchase: When to Market Your Directors and Officers (D&O) Liability Insurance for Best Terms for market timing tips.
Final thought
There is no one‑size‑fits‑all answer. For US companies in New York, San Francisco, or Houston, the decision must balance capacity needs, claims handling preferences, and market dynamics. A seasoned broker with deep relationships across national carriers (AIG, Chubb, Travelers, Beazley, etc.) and an ability to run both tower and single‑carrier scenarios will deliver the best placement outcome.
