Top Endorsements That Matter in Directors and Officers (D&O) Liability Insurance and When to Request Them

Directors and Officers (D&O) liability insurance protects company leaders from personal loss when they’re sued for alleged wrongful acts in managing a company. Base D&O policies provide core protections, but endorsements, riders and policy extensions are where coverage is tailored to real-world risks. This article, focused on the United States (with examples from New York, San Francisco, Los Angeles, Chicago, Austin and Houston markets), explains the top D&O endorsements, when you should request each, and the approximate cost and negotiation considerations.

Quick primer: why endorsements matter

Base D&O forms are standardized and often contain exclusions or limits that do not match a company’s exposures. Endorsements:

• Fill coverage gaps (e.g., regulatory investigations, EPL claims).
• Expand who/what is covered (e.g., Side A Enhancement, Side C/Entity).
• Extend reporting periods after a sale or shutdown (run‑off/tail).
• Change wording that can mean the difference between acceptance and denial of a claim.

Knowing which endorsement matters and when to insist on specific wording is critical for boards, risk managers and M&A parties.

Top endorsements and when to request them

1. Side A Enhancement (or Side A Difference-in-Conditions)

• What it does: Protects individual directors and officers when the company cannot indemnify them (bankruptcy, insolvency, or indemnification prohibited).
• When to request:
  • Pre-IPO or recently public companies.
  • Companies with thin balance sheets or high bankruptcy risk (e.g., early-stage tech firms in the San Francisco Bay Area).
  • Boards in litigation-prone industries (financial services in NYC).
• Typical cost impact: ~5–25% premium increase (depends on limit purchased and insurer appetite).
• Key negotiation points: Definition of “insured person,” carve-outs for fraud, and whether it stacks above Side B.

2. Employment Practices Liability (EPL) Extension / Employment-Related Claims Rider

• What it does: Extends D&O to cover employment-related claims (discrimination, harassment, wrongful termination) either as a shared limit or separate sub-limit.
• When to request:
  • Rapidly growing companies (Austin, Houston tech and energy firms) with hiring surges.
  • Post‑merger entities with workforce integration risks.
  • Industries with high EPL frequency (hospitality, retail, healthcare).
• Typical cost impact: ~10–40% or standalone EPL premium if insured separately.
• Tip: Consider purchasing separate EPL limits if exposure is high — it often provides broader coverage and higher limits.

3. Regulatory & Investigations Extension

• What it does: Covers costs associated with responding to regulatory inquiries, subpoenas, and investigations (including SEC, DOJ, state attorneys general).
• When to request:
  • Public companies and private companies in regulated industries (banking, healthcare, energy).
  • Companies subject to frequent government oversight (NYC financial firms, California biotech).
• Typical cost impact: ~10–35% depending on scope (civil vs. criminal defense support).
• Source: Market practices and insurer product notes (Aon, Marsh).

4. Securities Claims Extension (for public companies)

• What it does: Broader coverage for securities claims—class actions, shareholder derivative suits, disclosure claims.
• When to request:
  • Publicly traded companies and SPAC targets.
  • Companies planning an IPO or secondary offering.
• Typical cost impact: premiums vary widely; public company placements commonly range from tens of thousands to millions annually depending on company size and limits. Mid-market public companies often see premiums in the $100k–$1M+ range for multi-million-dollar aggregate limits.
• Source: Market trend observations (Aon, Marsh).

5. Run‑off (Tail) Coverage

• What it does: Extends the D&O reporting period after a transaction (M&A), wind-down, or policy cancellation so claims-made coverage still applies to acts prior to expiration.
• When to request:
  • Any merger or acquisition (buyers often require sellers to purchase run-off).
  • Company dissolutions, bankruptcies, or when removing directors.
• Typical cost impact: ~100–300% of an annual premium for extended reporting periods (varies by length; shorter tails cost less). For example, a 2-year tail might be around 150% of the expiring annual premium.
• Negotiation tip: Buyers typically negotiate sellers to purchase run‑off; get multiple insurer quotes because pricing varies.

6. Broad Form or Expanded Insuring Clauses

• What it does: Closes known coverage gaps (e.g., expanding “loss” definitions, removing public‑policy exclusions).
• When to request:
  • After claims or near-miss events where an exclusion almost triggered a denial.
  • Companies with a history of aggressive claims or regulatory scrutiny.
• Typical cost impact: variable — agrees more on wording than price; sometimes free with trade-offs.

7. Side C / Entity Coverage Endorsement

• What it does: Covers the corporate entity for securities claims (company is named as defendant).
• When to request:
  • Private-equity portfolio companies (buyers may require Side C).
  • M&A targets where buyer wants entity-level protection.
• Typical cost impact: 10–50% added premium depending on limits requested.

8. M&A / Change-of-Control Carve‑ins

• What it does: Preserves coverage despite transactions, or provides specific coverage for representations & warranties and post‑closing claims.
• When to request:
  • During buy‑side or sell‑side negotiations.
• Typical cost impact: charged as an incremental premium or flat fee tied to transaction scope.

Market context: D&O pricing and appetite vary by sector and geography—New York financial firms and California tech companies often face higher rates due to regulatory and securities exposure. Consult market reports for current cycle dynamics: Aon, Marsh and NAIC resources provide regular updates (examples: Aon, Marsh market insights).

Practical negotiation tips

• Start with clear underwriting information: revenue, balance sheet, claims history, governance practices, board composition and regulatory interactions.
• Package endorsements: insurers often price combinations (e.g., Side A + run‑off) more favorably than stand‑alone buys.
• Ask for specific carve‑backs rather than broad exclusions when possible.
• Use a broker with D&O experience in your geographic market (NYC, SF Bay Area, Los Angeles, Chicago, Austin, Houston) to shop multiple carriers and secure favorable wording.
• For M&A: build endorsement requirements into purchase agreements and insist on quotes/commitments early.

Conclusion

Endorsements are not optional extras — they are essential tools to align D&O coverage with real exposures. Whether you’re a small private company in Austin planning a growth hire surge (EPL), a public company in New York facing securities exposure, or a PE seller negotiating run‑off costs, knowing which endorsements to request—and when—will materially affect the protection your directors, officers and entity receive.
