Insurance Curator Directors & Officers (D&O) liability insurance is rarely a one-size-fits-all product. Standard policies provide baseline protections, but endorsements, riders and policy extensions tailor coverage to the company’s risk profile. In the U.S., where securities suits, regulatory investigations and employment claims concentrate in hubs like New York City, San Francisco, and Chicago, choosing the right endorsements can materially reduce exposure — but they come at a cost. This guide helps U.S.-based companies weigh cost vs benefit for the most common and consequential D&O endorsements.
Why endorsements matter (quick overview)
- Standard D&O policies separate coverage into Sides A, B and C. Endorsements modify scope, limits and who’s covered.
- Endorsements are most relevant when a company faces:
- Public company exposures (securities litigation)
- M&A transaction risk
- Increased regulatory scrutiny (SEC, DOJ, state AGs)
- Employment practice disputes (EPL claims)
- Market conditions and claim frequency influence pricing. Recent market surveys highlight pricing pressure for D&O across sectors, especially for larger public companies and companies targeted by securities suits (see Marsh market commentary) Marsh D&O Market Report.
The core endorsements: what they do and typical U.S. cost ranges
Below is a practical comparison of common endorsements U.S. policyholders evaluate. Figures are U.S. market ranges; actual quotes will vary by industry, jurisdiction (Delaware/NY/CA exposures often drive higher pricing), company financials and claims history.
| Endorsement / Rider | Typical incremental premium (U.S. ranges) | Primary beneficiaries | When it’s usually worth it |
|---|---|---|---|
| Side A Enhancement (including additional limits for non-indemnified directors) | $1,500 – $50,000+ (depends on limit uplift; often 5–40% of base premium) | Individual directors | When directors require standalone protection (startups, bankruptcy risk, M&A transactions) — see How a Side A Enhancement Endorsement Changes Directors and Officers (D&O) Liability Insurance Protection |
| Side C / Entity Coverage expansion | 10–50% of base premium | The company (entity-level loss) | When SEC/stockholder suits or regulatory fines are a material risk (public companies or private companies with IPO plans) |
| Employment Practices Liability (EPL) extension / Side A for employment claims | 10–40% extra (or standalone EPL policy $5,000–$50,000+) | Directors & company | For companies with >50 employees, frequent HR issues, or presence in high-litigation states (CA, NY) — see Key Riders to Consider: Employment Practices, Regulatory Investigations and Securities Extensions for Directors and Officers (D&O) Liability Insurance |
| Securities / IPO carve-in (broad securities coverage) | 15–60% (higher for public companies) | Officers/Directors/Company | Essential for public companies or pre/post-IPO lifecycle in NY/SF markets |
| Regulatory investigations / Fines & Penalties (where insurable) | 10–30% (subject to insurability limits) | Directors & company | When operating in regulated sectors (financial services, healthcare) |
| Run-off / Tail coverage (post-termination) | 150–400% of annual premium for 1–3 year tail; can be quoted as flat fee | Former directors & company | When management leaves or company is acquired/sells assets — see When to Add Run‑off, Side C or Entity Coverage Endorsements to Your Directors and Officers (D&O) Liability Insurance |
| Broad form or deleted wording restrictions (e.g., deletion of “conduct” exclusions) | $2,000–$20,000+ depending on insurer | Directors & company | When policy wording gaps could otherwise lead to contested coverage in high-stakes claims |

Factors that drive endorsement value for U.S. companies
- Company status and jurisdiction
- Public companies (listed in NY, Nasdaq) face higher securities exposure; securities endorsements are often essential.
- Delaware corporate law and shareholder litigation create elevated D&O risk for companies incorporated in Delaware.
- Industry & regulator intensity
- Financial services, healthcare, biotech — elevated regulatory enforcement risk; add regulatory investigation endorsements.
- Size & headcount
- Larger headcount increases EPL frequency and severity — EPL riders or standalone EPLI often justified for companies over 50 employees.
- M&A activity
- Buyers/sellers often demand Side A or run-off protections; M&A-tailoring endorsements may be cost-effective during transactions (see Tailoring Endorsements for M&A Activity).
- Claims history and governance quality
- Weak governance or prior claims increase pricing; better governance programs can reduce premiums and endorsement costs.
Example scenarios (U.S.-focused) — is the endorsement worth it?
- Startup in San Francisco (pre-IPO), 25 employees, VC-backed:
- Consider Side A enhancement and securities carve-in as the company moves toward IPO. Typical add-on cost: 10–30% of base D&O premium. Benefit: preserves directors’ personal assets during indemnity shortfalls.
- Mid-market private company in Chicago, 300 employees:
- EPL extension or standalone EPLI likely worth the premium given employee count and state-level employment litigation. Expected incremental premium: $10k–$40k annually depending on payroll and exposures.
- Small public company listed on Nasdaq, HQ in New York:
- Securities extension, enhanced Side A and broad form endorsements are often essential; incremental premiums can total tens to hundreds of thousands of dollars annually for meaningful limit increases given high securities-litigation exposure (Cornerstone Research data shows persistent securities-class-action activity affecting pricing and defense costs) Cornerstone Research Securities Filings Report.
Negotiation tips to improve cost-effectiveness
- Bundle endorsements with multi-year agreements. Insurers often price competitiveness for 2–3 year deals.
- Consider layered capacity: buy a primary D&O tower with a narrower, cheaper endorsement and place excess limits with another carrier.
- Strengthen governance and compliance programs — insurers penalize weak governance and reward documented improvements with lower premiums.
- Ask for sub-limit vs. full-limit options (e.g., Side A enhancement with a sub-limit for certain regulatory investigations) to reduce cost while retaining meaningful protection.
- Use market competition: large carriers (Chubb, AIG, Travelers, Allianz) price differently by region — get at least 3 competitive bids (especially in New York and California markets).
Red flags and common traps in endorsement wording
- Narrow definitions of “loss” or overly broad “conduct” exclusions can nullify a rider’s practical value. Compare wording across quotes.
- “Carve-outs” for fraud, intentional acts or ERISA violations may leave gaps; confirm retentions and indemnification interplay.
- Run-off offers that require non-renewal of other coverages can have downstream implications for buyers/sellers.

Bottom line: a decision framework
- Map exposures (securities, employment, regulatory, M&A).
- Price quotes for targeted endorsements from multiple carriers (include major U.S. insurers such as Chubb, AIG, Travelers, Allianz) — ask for specific endorsement wordings and premium breakdowns.
- Compare incremental premium vs. potential claim severity (consider defense costs and reputational impact in NY/CA/DE jurisdictions).
- Negotiate wording, limits and retentions — prioritize endorsements that protect directors personally (Side A enhancement) and those that close high-frequency gaps (EPL, regulatory investigations).
- Reassess annually or when corporate events occur (financing, IPO, M&A, bankruptcy).
Selecting endorsements is a balancing act: some will be mandatory (for public companies or during M&A), while others are optional but cost-effective depending on jurisdiction and operations. Use competitive quotes, careful wording review, and a governance-driven risk reduction strategy to get the best cost-to-benefit outcome for your U.S.-based organization.
